Lasers firstly used to cure skin conditions some 40 years ago, since then there has been great advancement in laser technology and greater leaps in its use for treating many health conditions. Its wide use in medical science lies in its ability to effect only specific points leaving the surrounding area untouched.
WHAT IS LASER?
Laser stands for Light Amplification by the Stimulated Emission of Radiation, they emit focused pulsating beams of light. Its use is based on its ability to direct a microscopic beam of light of certain wavelength on a very short area. Leaving the surrounding area unaffected which makes it useful to target as area as small as the cell of the skin.
Lasers are using in different ways, they may be used to reach deeper layer of skin. Without affecting the surface or they may be used to take off the surface of skin. It is gaining popularity owing to its multi-pronged viability. Broadly lasers are classified into two categories.
Based on the mode of their working and they are Ablative and Non-ablative lasers.
Now even fractional lasers(advanced technology) in both these categories of lasers are available. The difference between classic and fractional lasers is classic works on the entire area while fractional is controlled to work in pre-determined columns to aid the healing process.
In medical field, they were first used some 40 years ago and since then they have been subject of much research and advancement.
ABLATIVE LASERS VS NON-ABLATIVE LASERS
Ablative lasers use a wavelength of light that removes the outer or sometimes even the inner layer of sun damaged or aged skin Like CO2 Laser, Erbium YAG Laser.
Non-ablative lasers leave the surface of the skin intact while reaching deeper into the skin and heating the appropriate cells in order to stimulate them to produce desired results and includes Intense Pulsed Light (IPL) Devices.
Ablative lasers work best in decreasing wrinkles, skin discoloration, sun damaged skin, acne or chickenpox scars, age spots and are more effective than non-ablative lasers.

Non-ablative lasers are non-invasive and good for open pore reduction, mild scars, mild wrinkles and age spots.
Downtime in Ablative lasers is significant as much time is taken in healing the skin, while in non-ablative lasers is much lesser. Side effects of ablative laser treatment are more severe and take longer to go away while that of non-ablative lasers lesser in severity and take a short time to recover.
In the coming paras, we will talk about various skin conditions and the type of laser used by dermatologists to treat them. We first start with the most harmless of conditions and that is unwanted hair growth.
Laser Hair removal
Laser Hair removal procedure is gaining popularity for permanent hair removal in Delhi. In this method, unwanted hair on any part of the body are removed using targeted pulses of laser. Laser beams of appropriate wavelength that are able to penetrate the skin deep enough to destroy hair follicles are used.
They work on the principle that lasers can cause selective heating of melanin in the hair follicle until it overheats and becomes defunct leaving the surrounding area unaffected.
With the damage to hair follicles, hair start shedding and no new hair growth is possible . Due to all this heating up, your skin might feel warm for sometime after the procedure .
Initially, use of laser hair removal in Delhi was limited to people with fair skin and dark hair since Lasers attacked the dark matter and in case of dark skinned people, lasers would heat up the melanin in the skin in addition to melanin in follicle.
But now with advancement of technology, it is possible to remove hair from dark skin, although with lesser degree of accuracy and success, however, laser technique cannot be used on hair having no pigment (melanin) like light blonde hair.
Will I need multiple sessions of laser therapy to remove hair permanently?
Yes, you will need multiple sessions in order to achieve optimal results. The span of growth and falling out of hair is divided into three phases
- Anagen Phase- This is the growth phase in which hair grows out of surface and achieves thickness and length and lasts about 3 years
- Catagen Phase: This is transition phase between growth and loss and lasts about 2 weeks
- Telogen Phase: This phase is dying phase and takes about 3 months for hair to fall off.
At any point in time, only a certain portion of hair are in anagen phase and it is hair in anagen phase that are attacked by laser because during the anagen phase the follicle are closest to the surface and consequently laser beam is able to reach the follicle, so multiple sessions spaced out according to patients rate of growth are needed to completely remove the hair.
Also number of sessions depends upon the speed of growth of hair. The faster the hair grow, more the number of sessions needed.
I have excessive growth, can this treatment help me?
Yes, this treatment can help people with all types of growth
Why am I regrowing hair after having undergone laser hair removal?
The results obtained by laser hair removal though very good , are, unfortunately not permanent. Age and hormone can outplay the technique resulting in growth of hair. You can always get additional sessions to have the new hair removed.
Why are different lasers used on different people?
The effectiveness of this technique is determined by wavelength of light produced by laser . Different skin types and hair colours will need different wavelength to produce results. Different kinds of lasers that are widely used are:
Ruby Laser: This was the very first laser used for removal of hair that was used only for people with fair skin. As it could burn people with dark or tanned skin since it attacked the melanin pigment.
Alexandrite Laser: This laser has the distinction of being called fastest laser till date. With large spot are (10mm) that can remove hair from entire back in 30 minutes. Used for people with fair to olive skin.
Diode Laser: This laser is primarily used on dark skin. It has deeper penetration range but small spot size with significantly increases the procedure time.
Erbium YAG Laser: This laser can be used on all skin types. It has large spot size and high repetition rate which makes it very fast. But it cannot be used to remove fine or thin hair.
Not much. When the laser is directed on your skin, you feel a prick sensation like snapping of rubber, other than that. Its pretty painless and think of the benefits of not having to shave.Wax the hair for the rest of your life unless age/hormones decide to play field.
What do I need to do before getting laser hair removal?
You will be advised to
- Not expose the area to be treated to sun.
- No waxing that area atleast 2 weeks prior to the treatment
- Not to use tanning creams, bleach i.e. do not darken the skin or lighten the hair
- Area must be clean shaven, for ease of access of laser beam to follicles
- No chemical or laser procedure should be done on the area for atleast 2 weeks prior to the laser hair removal
Post laser treatment care
- You can apply aloe gel to remove redness and irritation caused by the treatment
- You will be advised not to exercise for 2 days after the treatment, so all the sweat body produces does not aggravate irritation or redness caused due to treatment
- Do not expose the treated area to sun and wear broad spectrum sunscreen with SPF 30 or higher during and after the procedure.
- Do not puncture the blisters that may appear, use ointment on it instead
- Avoid putting on make up after procedure as it may cause irritation.
- Avoid additional laser treatment for atleast 2 weeks after the procedure.
- In case of continued redness, irritation, swelling, pigmentation or blistering, contact your skin specialist.
In this minimally-invasive treatment, concentrated beam of laser is passed through dye of a colour, the selection of which depends upon the color of the mark. It uses yellow colour light that targets blood vessels in the skin, which are destroyed due to over heating and resulting in lightening of mark.
It is a short procedure and success depends upon the fineness and colour of the spot. Coarse, thickened and dark spots may be difficult to cure. Multiple sessions are usually needed of this short procedure.
The pulsed dye laser is very effective at treating generalized redness, such as from rosacea, age spot and broken blood vessels among other skin conditions elaborated below.
Before using pulsed dye laser, patient will be advised to use sunscreen for a month to limit tan as sun tanning blocks the laser from reaching the affected blood vessels and may heat up other blood vessels, thereby destroying them. Most common side effect of this procedure is bruising and pigmentary changes which lasts for about a week.
After care includes application of moisturiser to keep the skin soft and accelerate healing. No make up for a few days and in case crusts are formed, do not pick them.
Most common problems treated using Pulsed-Dye Laser are:-
Also called Nevus Flammeus. It starts off as a pink mark at birth that darkens as the kid grows. It varies in size and can be found on any part of the body.
Unless found near eye or forehead which might be a associated with Sturge-Weber syndrome or Glaucoma, port-wine stains are essentially benign. Although port-wine stains are small and barely noticeable, they may grow in size and darken in colour with age and when found on face and neck, they can be upsetting for the kid.
Fortunately people have noticed lightening of the mark using laser called PULSED-DYE LASER.
It is also a kind of birthmark and is caused due to abnormal build-up of blood vessels. They start off as red mark on the skin and may turn purple and in some cases may advance upward as protrusion of extra blood vessels from the skin as time passes
They are commonly found on skin but may also grown on liver, kidneys, colon, lungs, brain cavity. It is non-cancerous and does not need treatment in every case unless the marks have grown hideous or they develop lesions or sores. Pulsed-dye laser is effective is used by cosmetic plastic surgeons or dermatologists.
Wrinkles are a natural side effect of aging and environmental vagaries. For a youthful skin, collagen, elastin and GAG all must be available in skin in ample quantity.
But in 20s, production of collagen starts decreasing. As a result skin gets thinner, drier and less elastic and less able to protect itself from damages by pollution, medications, cosmetics and sun with age which lead to formation of wrinkles. Smoking also accelerates the formation of wrinkles.
Fine lines or wrinkles can also be formed in some people at young age due to repeated smiling, frowning, squinting. Smiling, squinting, frowning involves contraction of muscles which leaves an impression on skin. When such impressions get accumulated over time, they leave fine lines or wrinkles around that area.
There is no avoiding wrinkles if you want to grow old but they certainly can be delayed by taking extreme care of skin and now, thanks to laser technology can even be reversed.
CO2 FRACTIONAL LASER RESURFACING.
This technique removes the outermost layer of skin tissue by vaporising it in columns leaving the skin surrounding the columns intact to aid in healing. It is the best available method to treat many skin conditions. The downtime is 7-14 days which the new skin takes to heal.
This time depends upon the depth of penetration of the laser , density of the area that was treated and how aggressive the procedure was. There is feeling resembling that of sun burn that may continue for a day or two.
Your surgeon/dermatologist will apply local anesthetic to numb the pain during the procedure and prescribe pain medication to manage the pain and antibiotic to prevent any infection after the procedure.
You will also be advised to remain indoors for a couple of weeks to let the skin heal properly without the damaging effect of sun and pollution.
Does this CO2 Fractional Resurfacing only help to reduce wrinkles?
No, it can be used to undo host of other skin conditions like freckles, liver spots, lentigines, scarring, fine lines, sagging, textural irregularities, uneven coloration, skin laxity, dull tone, heal a thinned collagen layer.
Is wrinkle treatment permanent?
Wrinkles are formed due to working of facial muscles. To have a permanent effect, facial muscles will need to be damaged so there won’t be any contraction and consequently no grooves will be formed and hence no wrinkles. But with non-functional facial muscles you wouldn’t be able to laugh, eat, squint etc. So no doctor in their right mind will cater to your wishes of permanent treatment of wrinkles.
LASER SKIN RESURFACING
Laser skin resurfacing involves removing layers of skin to bring out healthier, rejuvenated and glowing skin.
Resurfacing cures facial wrinkles, blemishes, acne scars, wrinkles under eye or on forehead, damaged skin from facelift, enlarged oil glands on nose, loss of skin colour.
Ablative lasers are mainly used in skin resurfacing. Strict precautions are needed to be taken before, during and after the procedure to achieve optimal results.
After care is of utmost importance in these procedure as new skin is very tender and will need extreme care and caution to heal. A risk of infection and wounds is always there when ablative lasers are used.
Redness, swelling etc reduces with time and in 2-3 weeks a new , rejuvenated and glowing skin is formed.
I have dark skin, is laser treatment not for me?
It is true that certain lasers pose a greater danger of hyper-pigmentation/cell damage on darker skin but due to advancement of technology, now safe options are also available.
Your doctor will guide you to the type of laser best suited according to the skin.
Is laser treatment painful?
Ablative laser (also called wounding lasers as they involve removing of layer of skin) do cause some pain. Pain depends upon the depth, area and aggressiveness of treatment, as also patient’s capacity for pain tolerance. Usually where the doctors anticipate pain, they give local anesthetic injections to make pain manageable.
Non-ablative lasers do not cause much pain as they do not remove layers of skin but only passes through them.
Acne is caused when pores in skin get clogged by
- Excessive oil produced by skin’s oil glands
- Dead skin cells
- Ingrown hairs
Acne may also be caused by hormonal changes that cause obstruction of sebaceous glands in the skin. Acne is of two types-: non-inflammatory and inflammatory.
NON-INFLAMMATORY ACNE is the acne which has no swelling or redness associated with it and includes Whiteheads and Blackheads.
These also called Closed comedones, are caused by clogging and closure of pores by skin oil secretions, debris and dead skin cells. They appear as small, closed white bumps on skin. They usually are found on face, neck, shoulder, chest and back and are painless but they may cause social anxiety.
Whiteheads may be caused by a variety of reasons that includes genetics, dietary habits, puberty, stress. Whiteheads do not generally need any treatment but in a severe case, your dermatologist will prescribe a cleansing routine depending upon your skin type and severity of breakout and medicines to fight and prevent whiteheads.
It also called Open comedones are caused by clogging of hair follicles by dead skin. A hair follicle contains a hair and sebaceous glad that secretes sebum needed to keep the skin soft. Sometimes dead skin enters the follicle, mixes with the oil and plugs the pore.
Unlike whitehead, skin around the plugged pore opens and sebum oil is oxidized to give a black coloured appearance to the acne, hence gaining the name Blackhead. Excessive production of oil (sebum) in follicles is the main cause for this acne.
Hormonal changes, sweating and some medications can cause the sebaceous gland to secrete more oil. Dermatologists advise against scrubbing or squeezing blackheads. Luckily over-the counter remedies like pore strips are available for light breakout. In severe case, however, you must consult your skin specialist.
It derives its name from redness, swelling associated with it. Milder inflammatory acne includes papules and pustules, severe categories include cysts and nodules. Cysts and nodules are difficult to manage without proper treatment and usually leave blemishes.
These small bumps contain dead cells, sebum, bacteria and are formed when bacteria causes irritation of hair follicle and are red or pink in colour. They donot contain pus and are surrounded by skin inflammation. Unless there is a huge breakout, they are easy to cure with dietary changes and medicines as suggested by your skin specialist.
These are formed when bacteria cause inflammation of hair follicles and contain pus, are tender to touch and may be painful too. They appear as white solid elevation with red surrounding. Squeezing them is not advisable as pus and clogged bacterias etc oozed out on skin due to squeezing may cause irritation and leave scars.
Your dermatologist will first prescribe you treatment for killing bacterias so sebum and dead skin cells can rise to the rise and come out and then suggest you a diet and medications to deal with the remaining contents.
Cysts: Cysts are formed when inflammation of follicle results in its rapture and infection goes deep in the skin. This is a severe form of acne and can appear unsightly and painful to touch. Cysts must never be picked and a dermatologist should immediately be consult to stop its growth and prevent further cysts. Another downside of cysts are they leave stubborn scars if left untreated.
Nodules are hard acne lesions formed deep with in the skin and are found on large areas like chest and back and are very painful.
Unlike other form of acne, they may persist for months and harden into solid mass within the skin and may be difficult to treat. This is the severest form of acne and is capable of leaving deep scars which the dermatologists may have a hard time erasing.
Acne can be treated by medical therapy as well as laser therapy and what medicines or laser will suit you best can only be known by a skin specialist. Acne scars also paint a same story, scars may range from small to big, light to dark.
They will also require expert care if you want to get rid of them and out of technologies now available in the market laser is the best. Laser treatment can also be used to treat acne in addition to topical medicines. Laser therapy works in various ways depending upon the need of the scarring. It can remove the outermost layer of the skin.
How can laser help reduce acne?
- It excites porphyrins present in bacteria that in turn breaks the bacterial wall thereby killing bacteria with the heat produced.
- Lasers are also known to limit the production of sebum and lower the sebum oil, lesser probability there is of acne.
- Lasers have anti-inflammatory characteristics.
Why do acne leave scars and discolouration?
When acne occurs, skin produces collagen to heal the acne, and the excess collagen left can form scars. Also inflammatory acne produces melanin in excess which can lead to post-inflammatory hyper pigmentation (PIH) which cause skin discoloration.
Which lasers are used to treat acne scars? How are scars removed using laser?
CO2 Fractional Laser and Erbium YAG Laser.
Lasers are now being used to treat psoriasis (recurring problem appearing as thick, red patches with silvery scales). UV rays through the laser are fired only to the affected area and in 8-20 weeks depending upon the severity of psoriasis. Patients have noticed thinning of red patches and decrease in scales.
LATEST ADVANCEMENT IN FIELD OF LASER TREATMENTS
Psoriasis is known to respond to UV rays but in traditional methods whole of the body of the patient is exposed to UV rays. So a big advantage of this method is its localized effect on the affected area.
Why do I need different types of laser treatments for different conditions?
Good question. The science behind needing different lasers for different skin conditions is based on wavelength. Light has different wavelengths, like yellow will have a wavelength different from red and so on. Sunlight has all wavelengths in it since it is combination of all lights. Now certain things absorb certain wavelength only and will remain unaffected by rest of the wavelength.
That is to say, brown spot like absorb light of one wavelength and reflect back light of all other wavelength. This selective absorption is what makes laser therapy so effective. Since it only fires its energy only on the target area leaving the surrounding area unaffected. Laser can target an area as small as a stem cell.
Can I have mole removed by laser therapy?
Though moles can be removed by laser therapy but it is not recommend. Moles are excessive growth of skin which is usually non cancerous .But in a rare case they may be a symptom of cancer.
And removing mole using laser will destroy its cells. Making it impossible to test the cells for possible cancerous growth in body.
Warts occur when Human Papillovirus (HPV) enters the skin through openings or break out in skin caused by cuts. HPV causes skin of the infected area to grow rapidly and form a bump which is called a wart. Warts are generally benign but are contagious.
They can spread from one body part to another if you pick or touch the wart. And touch another body part without washing your hands. Or they can spread from one person to another through contact with any object.
That has touched warts on infected person like towels, razor.
