Skin is the largest and the most visible part of our body. Performing many functions, starting from sense to protection, it suffers all the environmental chaos, the use of harsh products and many other external and internal torments. Any problem, in whichever part of the body, will affect the skin for sure. Age is another factor that affects the skin.
Whatever may be the reason or the problem, skin shows it all, especially on the face. Skin conditions include blemishes, acne, wrinkles etc. The list is never ending. Ageing brings dark circles, sagging skin, wrinkles etc. Anti- aging products, medications, etc. all promise to redress these skin problems. But most of these promises remain unfulfilled! That is when people turn to laser treatments!
What Is Laser Treatment For Skin?
Lasers are sources of high intensity light. It accurately focuses on small spots with high energy.
The laser beam can gently vaporize and/or ablate the skin tissues to treat wrinkles, scars and blemishes, seal blood vessels or cut skin tissue. Broad spectrum of the Intense Pulsed Light (IPL) has the ability to specifically treat blood vessels and pigmentation. The technique directs short, concentrated pulsating beams of light at irregular skin, precisely removing the skin layer by layer.
Skin Conditions That Laser Can Treat:
Laser therapy is used to treat varied skin conditions and ailments, including:
- Unwanted hair
- Unwanted tattoos
- Acne scars
- Aging skin problems, such as age spots, fine lines and wrinkles on the face
- Birthmarks
- Spider veins
- Droopy, dry, sagging eyelid skin and dark circles
- Improve crow’s feet around the eyes
- Pucker marks and frown lines
- Brown spots and uneven skin color
- Scars
- Uneven skin tone and texture
- Smokers’ line
- Vascular lesions
- Skin tightening
With the new improved and advancing technologies, many other skin problems and diseases too can be treated using Laser therapy.

Types Of Lasers:
There are several types of lasers used in skin laser therapy. The wavelength peaks of the laser light, pulse duration and how the target skin tissue absorbs this, determine the clinical applications of the laser types. The broad two categories are:
Ablative Lasers:
In this procedure, an intense wavelength of light is ejected into the skin, which removes the outer layers of aged or sun damaged skin. Laser stimulates the underlying skin, resulting in collagen formation and an improvement in wrinkles. After laser resurfacing, an ointment and dressing is applied to the skin. Once the skin heals after the treatment, new skin forms that is smoother and tighter. Ablative Lasers are of two types:
1. Carbon Dioxide Laser (Co2):
It was first introduced during the late ’60s and is still being used for skin rejuvenation. Due to its side effects, it has largely been replaced with fractional mode lasers, which has fewer side effects and heals faster. It is not apt for darker skin tones.
Skin Conditions: It is used in case of skin cancer, acne scars, deep set wrinkles, birthmarks, other scarring warts, moles, skin tags, saggy skin (encourages collagen production for skin tightening), corns on feet, and sun damage.
Side Effects: It takes long time to heal huge risks of pigmentation, pain, itching and burning sensation, skin redness and scarring.
2. Erbium Yttrium-Aluminum-Garnet (Er:YAG):
It helps remove surface-level and moderately deep lines and wrinkles on the face, hands, neck or chest with minimal burning of surrounding tissues. With lesser side effects, it heals faster than CO2 Laser treatment.
Skin Conditions: It is used to cure pigmentation problems, acne scars, sun damage, fine lines, small to moderate wrinkles, and moles.Side Effects: It may cause redness, swelling, and bruising, which may last for 1-2 weeks.
Non-Ablative Laser:
Unlike ablative technologies that heat and remove the top skin tissue, non-ablative (or non-wounding) laser work beneath the surface skin layer. It stimulates collagen growth and tightens the underlying skin to improve the skin tone. It also removes fine lines and mild to moderate skin damage.
Non-Ablative Laser-based treatments are of the following types:
1. 808nm Diode Laser:
The effective penetration depth of 808nm diode laser can reach the target tissue Dermal papilla. The appropriate pulse duration of the target is sufficient heat damage and the surrounding tissue is barely affected. Provide sufficient energy output to damage the target tissue and normal tissue is almost unaffected. Skin protection measures to guarantee enough target tissue damage. To ensure the safety of the treatment. Under the mode of low energy density, the hair follicles were heated to 75℃ and the hair follicle and growth stem cells were deprived of the growth activity by the sliding maintenance of the treatment hand and the hair follicles(10hz state).
Powerful upgrade are more secure, fast, painless, efficient, it’s your preferred hair removal device.The laser selectively acts on the melanin in the hair follicle, which destroys the germinal region in the hair warm.
Natural hair shedding, to achieve the purpose of hair removal.
Stimulate collagen regeneration, reduce the pores, make the skin tight smooth at the same time.
2. Nd: Yag Laser:
Neodymium-doped Yttrium Aluminum Garnet is a crystal that is used as a laser medium for solid-state lasers. These emit a wavelength of high energy light, which when focused on a certain skin condition, creates heat and destroys the diseased cells.
Skin Conditions: It is helpful in treating vascular lesions, pigmented lesions, skin pigmentation problems, spider veins, tattoo removal and hair removal.
Side Effects: It has a low success rate. In case of vascular lesions, there is a high chance of recurrence. There can be pain during the treatment. Redness, swelling and itching may last up to several days after the treatment.
3. Alexandrite Laser:
This laser emits wavelength of high energy light that is converted to heat energy. This damages the specific target area. This laser uses the process of photothermolysis, which means using light (photo) to heat (thermo) a selected area for destruction (lysis). Alexandrite lasers cause very precise tissue destruction of the lesion and leave tissue in the surrounding area undamaged.
Skin Conditions: It is used to treat brown spots due to sun damage, birthmarks, pigmentation, and pigmented lesions. It is useful for hair removal, tattoo removal and leg veins.
Side Effects: Pain during treatment is common. Redness, swelling and itching may last for a few days. It may also cause changes in pigmentation.
4. Cryolipolysis Slimming Weight Loss Fat Freezing:
Cryolipolysis is a proven procedure to reduce fatty cells by using the Integrated Technology of cryo,vacuum and IR(infrared light). Its principle relies on controlled cooling for non-invasive local reduction of fat deposits to reshape body contours. The exposure of cooling is set so that it causes cells death of subcutaneous fat tissue without apparent damage to the overlying skin. The system is a non-invasive cryo-cooling treatment and the combined treatment of Cryo and Vacuum performs effective remove localized fat and promote fat metabolism.

Light-Based Treatments:
The light-based treatments are also used to cure skin problems. Though they are not exactly laser treatments, but are similar to it in terms of purpose, procedures and results.
Some of the Light based treatments are:
- Intensed Pulsed Light
- Pearl by Cutera
- Photo Facial
- Portrait
- Pulsed Dye Lasers
- Radiofrequency
- Ultrasound Imaging
Results And Recovery:
The results of laser and light-based treatments vary, depending on the technology and treatment. When properly performed, laser and light-based treatments can visibly improve the skin conditions and problems. And they also rejuvenate the skin.
Recovery too, varies, depending on the type of procedure employed. Mild treatments, such as those with low-powered lasers typically have very fast recovery times, generally a few days to one week. This type of treatment does not result in heavy peeling, oozing or crusting of the skin. Aggressive laser treatments require a longer recovery period. Typically, the skin will go through various stages of redness, oozing, crusting and peeling for one week. After that, the skin may remain pink for up to another two weeks.
Is It Safe?
Laser is a surgical procedure and all surgical procedures carry some risk. Ablative laser and light-based treatments can result in infections, cold sores, milia (small white elevated cysts of superficial skin), darkening of the skin (particularly if exposed to the sun after surgery) or cysts.
Non-ablative techniques can cause temporary hyper pigmentation (skin darkening), blisters, and damage to the eyes from laser exposure.
With advancing technology, there are new types of lasers being introduced for various skin problems and skin types. And with so many different types of laser skin treatments available, it is difficult to zero in on the one that will work for you. So it is very important to consult an experienced dermatologist to finalize the treatment plan, tailor-made for you!
