Ablative laser resurfacing uses light energy to eliminate the upper reaches of the skin and can lead to unwelcome consequences such as redness, itching, and swelling. There are risks associated with the procedure, which may include bleeding, infection, changes in skin color, and scarring. Non-ablative laser resurfacing, which does not remove the outer layers of the skin, can also cause side effects, including skin color changes, mild swelling, and redness. Individuals with an autoimmune disease, a tendency to form scars, or a history of cold sores, as well as those with a darker skin tone, are pregnant, or are breastfeeding, might not be the best candidates for laser skin resurfacing. However, there are other effective treatment options that you can discuss with Dr. Thompson.
