How Acne Scar Laser Treatment Works

While scarring isn't usually the result of acne, picking, itching, and squeezing pimples may result in irreversible damage. The good news is that one treatment that helps lessen the appearance of acne scars is laser therapy. 

Ablative Laser Therapy

Abrasive (sometimes called resurfacing) and non-ablative lasers are the two main types of lasers utilized on depression-related acne.

The most widely utilized and possibly dangerous lasers are relative lasers. The outer layers of skin are actually destroyed by these kinds of lasers. They remove scar tissue by burning it, which causes the skin collagen to contract. This thereby lessens the visibility of the scar. Until the skin completely heals, this therapy leaves the afflicted region very red, sensitive, and painful. Furthermore, it may need many months to a year for the injured region to fully heal, therefore it's critical to tend to it and take precautions against infection. Dressings, antibiotic ointment, and soaks are used for this. There are no wrinkles or acne scars on the skin that does regenerate. The most common lasers used in laser resurfacing are the erbium YAG and ultrapulsed carbon dioxide lasers.

Non-Ablative Laser Therapy

On the other hand, nonablativNon-Ablative Laser Therapye lasers do not harm the skin's outer layer. Rather, they reduce acne scars by promoting collagen formation. The nonablative laser therapy for acne scars has to be repeated, but the ablative laser treatment just needs to be done once. One of the newest lasers for this therapy that the FDA has authorized is called Smoothbeam. This works by heating the sebaceous gland in order to decrease sebum, which may cause acne. Heat-treated collagen tightens the dermis and reduces the visibility of scars.

Pulsed Dye Laser (PDL) for Raised Scars

A new kind of laser is needed for raised acne scars, also known as keloids and hypertrophic scars: the pulsed dye laser (PDL). A PDL treatment may help flatten a raised scar, lessen its color, and lessen itching and discomfort. A focused laser beam is used in the PDL procedure to target skin blood vessels. The surrounding skin is unharmed while the blood artery is destroyed by the light's conversion to heat. Because the laser employs yellow light, which doesn't cause long-term skin damage, it is very safe. PDL procedures often only take a few minutes, and anesthetic is not needed. Enhancing the look of keloids or hypertrophic scars may need many visits. Bruising is the most frequent adverse effect of this kind of therapy, but it is not severe. But this normally goes away in three to ten days. There may also be brief alterations in pigmentation, although these usually pass within a few weeks. Apply Sunblock to the afflicted region at least one month before to receiving PDL laser treatment. In fact, tanned skin obstructs the laser's light and raises the possibility of adverse consequences.  With this laser, scarring is quite uncommon.
