It can be used as often as needed; it depends on your skin type and personal preference. Those with normal skin can use this mask once per week or every other week as a "special treat" for their skin. Those with dry skin may want to use this mask more frequently, up to 23 times per week (including an overnight treatment one time per week).
Someone with very dry, dehydrated skin should use this mask (or a very emollient moisturizer) once per day, morning or evening, until his or her dryness has improved. As a general rule, pay close attention to how your skin is behaving on a daily basis, and use Skin Recovery Hydrating Treatment Mask accordingly.
