Timing is everything, depending on the settings and passes, your therapist will guide you as to the healing times. Generally I like to wait 3-6 days, depending on the products and your skin sensitivities. Though C and B is meant for a full face even application, good operators will lay extra laser areas where it is need, meaning treatments are always individualised. Hence we always guide patients as to their healing time and product use. Bland washes are advised for the first few days. Dr Davin Lim. The Fiori Institute of Skin and Body. Brisbane, Australia.
