Frequently Asked Questions
Can I mix retinol and vitamin C?
Best used at different times of day. Vitamin C in the morning, retinol at night. Using together can cause irritation and reduce efficacy.
Can I use multiple acids together?
Avoid layering strong acids (AHA + BHA + vitamin C) in the same routine. Space them out or alternate days to prevent barrier damage.
