Cosmetologists use a laser to reduce a scar's appearance and minimize pain and itching. Laser treatment can also prevent scars from forming after surgery.
The laser helps stimulate new, healthy skin growth. Although laser treatment cannot completely remove scars, it can make them less noticeable and uncomfortable.
People can get laser therapy on many types of scar, including surgical scars, acne scars, and scars from injuries. It is also safe to use on the face.
Laser treatment penetrates the outer layers of skin to stimulate new, healthy skin cell growth. The laser removes older, damaged layers of skin so that new, healthy skin can grow in its place.
Laser treatments are, in essence, creating a new scar in place of an old one. However, the new skin should grow more uniformly.
The formation of scar tissue is a natural bodily response to injury. Scars are not harmful and do not require removal for medical reasons. However, if they are painful, limiting, or affect a person psychologically, a range of methods can reduce their appearance and discomfort.
Doctors can choose from a variety of lasers that use different wavelengths of light and affect the skin in various ways. Some lasers are ablative, meaning that they remove the top layer of skin, while others are nonablative, retaining the skin's surface while affecting the layers underneath.
Some lasers may be unsuitable for certain skin tones because they may cause the skin to grow back discolored.
Examples of laser types that doctors use in scar treatment include:
A doctor should thoroughly evaluate a scar before recommending a laser for treatment use. They should explain the potential benefits unique to a particular laser as well as its possible side effects.
Laser treatment can help with many common types of scar, including acne scars and injury scars. Doctors tend to recommend it for superficial scars. Deep scars or scars that restrict a person's movement will typically respond better to more intensive treatment. A doctor may recommend laser treatment for the following types of scar:
Before a person undergoes laser treatment, a doctor will examine the scar and mark the skin with a pen to identify the area for treatment. The following is an example of how the treatment process may work:
The treated area may remain red for several hours after the procedure. There may also be mild swelling and stinging that might feel similar to a sunburn. After the procedure, doctors often recommend applying moisturizing lotion to the area at least twice daily and refraining from applying makeup until the redness has gone away.
