There may be some irritation, redness, and crusting may form on the treated areas. You can use makeup to cover any imperfections while the skin is healing after the first 4 hours.
Avoid direct sunlight immediately after the treatment. You can, however, go about your daily activities immediately as long as you are wearing 30+ SPF with reallocation every 2 hours. Do not exercise for 24 hours.
Generally, the treatment is immediate, and you only need one treatment. However, occasionally two sessions may be needed.
