FAQ
This mask is designed for weekly use. Using it more frequently may lead to over-exfoliation or irritation.
While it contains beneficial ingredients like Vitamin C and Niacinamide, the Lactic Acid can be potent. If you have very sensitive skin or are new to AHAs, it's recommended to patch test first or use it cautiously.
It's best to avoid using other strong exfoliants on the same day you use this mask to prevent over-exfoliation and potential irritation.
