Stop retinoids 3 to 5 days before treatment to prevent redness or peeling. Also avoid exfoliating acids (AHAs, BHAs) and consider pausing Vitamin C a day or two prior.

Makeup and thick creams can block light absorption and increase irritation risk. Keep your skin bare for the best results.

• Exfoliating makes your skin more sensitive before the session: Exfoliating right before blue light therapy isn’t a good idea because it can weaken your skin’s natural barrier and make it more sensitive to the treatment.
