Aftercare instructions are available and you should strictly follow these. Usually, this involves icing and the use of a bland moisturiser. The skin should be kept lightly moist for at least 2 days. Some patients experience peeling and scabbing. Make-up should be avoided until the skin is healed, this is usually up to 5 days.
