Sheet masks may be used as often as you wish during the day or week, although many experts recommend wearing them three times a week or once a day for added care. You can also use washcloth-style masks to cleanse your face thoroughly without applying makeup. When you wear a sheet mask, you are absorbing nutrients from the product into your skin. Because sheet masks contain many ingredients known for their benefits to skin health, they are ideal for treating damaged skin or skin that needs extra attention. Some examples of ingredients found in sheet masks include: fruit acids to exfoliate, herbs for their anti-inflammatory and antioxidant properties, minerals such as iron and zinc for their ability to support collagen production, and vitamins A, C, and E for their role in protecting against free radical damage. The most common forms of cosmetic treatments for aging skin include moisturizers, sunblocks, serums, and facials. While all of these products can offer significant benefits when used consistently and appropriately, they can also cause harm if used incorrectly or too frequently. It is important to understand the differences between these treatments so you can choose the option that best meets your needs.
