No matter your skin type, it is vital to include a moisturizer in your daily skin care routine. Due to a lack of natural protective oils, dry skin requires additional hydration to prevent it becoming tight, irritated, and flaky. In contrast, the removal of excess sebum from oily skin can strip it of its natural protection or lead to over-production of sebum. Using a moisturizer redresses this balance and protects oily skin. Normal or combination skin also requires additional protection to shield it from environmental aggressors and fight the effects of aging. iS Clinical Moisturizers not only hydrate and protect the skin, they also stimulate collagen production, boosting the skin’s natural elasticity.
