Acne scar laser treatment uses a high-energy light beam to burn away layers of damaged skin tissue. By inhibiting the growth of bacteria and shrinking sebaceous oil glands, acne lesions can be successfully treated. Laser treatment can be very effective for certain types of acne scars and can significantly improve the appearance of the skin but it isn't a magical cure that eradicates acne scars overnight.



There are two main types of lasers used in acne scar laser treatment, namely ablative (resurfacing) and non-ablative lasers. Ablative lasers burn away scar tissue by heating and removing the top skin tissue which stimulate the skin to tighten up, thereby rendering scars less visible.

This type of laser treatment is used to treat keloids or raised scars by flattening and reducing itchiness by preventing redness of skin. However, ablative laser resurfacing injures skin during treatment and skin may remain red for several months.

During the healing period, care has to be taken not to infect the wound. The procedure usually requires multiple treatments and results will only become apparent over a year after the last laser treatment. The patient has to endure several months of discomfort with sensitive skin and cover the red appearance with skin foundation.

Non-ablative laser treatment stimulates changes in the skin without injuring the epidermis. This kind of laser treatment works for less severe acne scarring. It works by heating the sebaceous gland to reduce sebum production and stimulates collagen to fill depressed areas. Non-ablative laser treatment is popular as it has few side effects and recovery is fast.

Laser treatment for acne scars can have varying success in results. Always consult your dermatologist who will conduct a full medical analysis based on your medical history, the condition and location of scars among other factors before deciding a suitable type of acne scar treatment.

Since acne scar laser treatment often requires multiple sessions of treatment, the cost can be quite high, running into several thousand dollars for the entire treatment period. Results also vary with each individual not only because the nature or severity of the acne scars differs for each person, but also that different people react differently to the treatment. Some who are lucky have skin that heals well while others may see little improvement or worse skin condition after treatment.

Expectations of perfect skin after laser treatment are unrealistic. Skin is very unlikely to heal to the point of original flawless skin. At best, acne scars are minimised and lightened to give an improved appearance. Perhaps the best remedy is to seek medical attention early before acne problems take root. This will reduce chances of permanent acne scarring which even acne scar laser treatment may not be able to get rid of satisfactorily.
