Hello, Swelling and sometimes blanching, is expected immediately post-treatment and generally resolves within 24-48 hours. It may last up to 3-5 days in some clients. Following a more aggressive treatment it may be helpful to use some occlusive ointment on the skin after treatment during the healing process to help minimize trans-epidermal water loss which may result in significant desquamation or crusting. To help remove debris and bronzing of skin that can appear 1 to 4 days after treatment, soak treated areas for 5 – 15 minutes with gauze or wash cloth wet with water, then gently remove debris. Do not pick at or scrub the treated areas. Gentle cleansing and use of non-irritating cosmetic are permitted after treatment, it is suggested that retinoids be discontinued 1-2 weeks prior to the initial treatment and throughout the course of treatment.In our practice we apply products that have growth factors that further helps healing and promotes collagen production. Good Luck.
