The fractional laser works both on epidermal and dermal layers.
Fractional lasers are an emerging technology which are safe and effective to use in several cosmetic indications. It is a minimally-invasive treatment that uses laser rays in a pixilated fashion to treat the targeted area on skin. The fractional laser works both on epidermal and dermal layers. Commonly used fractional lasers are CO2 laser and Er:YAG laser. CO2 laser is gold standard for post-traumatic, surgical scars and acne scar treatment. Also used for stretch mark treatment.
The laser beam causes columns of thermal injury over the skin, which initiates re-epithelialization and new collagen synthesis. The laser rays are targeted into the affected area leaving the unaffected surrounding area intact.
Skin rejuvenation: Fractional lasers are effective in stimulating collagen production, reduce the appearance of fine lines, wrinkles, and age spots.
Scar reduction: Fractional lasers are mainly used to treat various types of scars, including acne scars, surgical scars, and traumatic scars. By promoting collagen remodeling, leading to smoother and less noticeable scars over time.
Hyperpigmentation: Fractional Lasers help in reducing excess melanin, for hyperpigmentation issues such as melasma, sun spots, and freckles.
Stretch mark improvement: Fractional lasers stimulate collagen production and remodel the skin in areas affected by stretch marks. With multiple sessions, the appearance of stretch marks can be minimized.
Skin Resurfacing: Fractional lasers provide controlled and precise resurfacing of the skin, removing damaged outer layers and promoting the growth of new, healthier skin cells.
Minimal downtime: Fractional lasers offer the advantage of minimal downtime. Compared to ablative lasers recovery rate is much faster i.e., less downtime, and reduced post-procedure swelling and redness.
Customizable Treatment: Fractional lasers can be adjusted to different settings and depths, allowing dermatologists to cater the treatment based on the patient’s specific skin condition and desired outcomes.
Safe for various skin types: Fractional lasers can be used on a wide range of skin types, including darker skin tones
Long-lasting results: With the stimulation of collagen production, the results of fractional laser treatments can be long-lasting.
A qualified dermatologist can do fractional laser treatment. Firstly, a topical anesthetic cream is applied to the treatment area to numb the skin. Later the laser handpiece is held on the affected area, and depending on the area to be treated, condition etc., the required settings are used. Minimal burning sensation, redness, and swelling are present post-procedure which subsides within a few hours to few days. Post-procedure emollients and sunscreen are applied. There is scab formation post-procedure which lasts for 5-7 days. Advised to continue moisturizer and sunscreen daily and avoid sun exposure.
Some of the side effects include redness, swelling, scab formation, post-inflammatory pigmentation etc.
A minimum of 6 sessions with a gap of 4-6 weeks is required to achieve a desired result.
Fractional lasers are the emerging technology to treat scars and signs of aging where a laser beam is delivered in pixilated form.
Fractional lasers work by causing thermal injury to the affected area, hence initiating the new collagen synthesis and re- Epithelialization
Depending on the indication for the laser treatment, one may require 4-6 sessions, 4-6 weeks apart.
It is very effective in treating acne scars when combined with other modalities of treatment depending on the type and severity of acne scars.
Minimal side effects like swelling, persisting redness, hyperpigmentation etc may be noted.
Precautions include diligent use of sunscreen, avoidance of excess tanning, use the priming agents prescribed by your dermatologist regularly, stop the active creams 2-3 days prior to the scheduled appointment, inform your treating doctor about upcoming events or occasions so your treatment can be spaced out accordingly as this treatment as downtime.
Yes, even after stopping the treatment improvement continues.
Depending on the condition and severity, the number of sessions required differs.
Fractional lasers are suitable even for darker skin tones compared to ablative lasers.
