There can be some local irritation to the skin after laser treatment and the effect of skin resurfacing work begins to take effect. Some redness, swelling, and bruising are common. Depending on the type of laser treatment, you may also have some skin color changes, which are typically temporary. You may have some itching as the skin heals, which can easily be treated with medications. Antibiotics and antiviral medication can help prevent infection for patients for whom this has been an issue in the past. Proper aftercare, including sun protection and following the healthcare provider’s instructions, can help minimize these risks and promote effective healing.
