It depends on the type of mask. If it’s a hydrating mask, such as our Illuminating Pearl Mask, daily application is encouraged. If it’s a moisturizing mask, like our Coconut Honey Mask, we recommend 2-3 times a week. If it’s a clay-based or detoxifying mask and you have especially dry or sensitive skin, we recommend once a week. And, if you’re using the Resurfacing Facial Exfoliant, 1-2 times a week, especially since this treatment can replace your exfoliator.
