An oil-free salicylic acid face serum that reduces the formation of adult acne and improves visible signs of aging.
Blemish + Age Defense is a targeted, oil-free approach for aging skin prone to acne breakouts. This first-to-market acid blend combines 2% dioic acid with an optimal alpha- and beta-hydroxy acid formulation to reduce the formation of acne and clogged pores, while improving the appearance of fine lines, wrinkles, and uneven skin tone.
THE SCIENCE
How Adult Acne Forms
Acne in the adult years is often a result of hormonal changes, stress, or extrinsic factors. Adult acne forms when sebaceous glands become enlarged and increase sebum production, blocking pores and the cell renewal process. As a result, blemishes, excessive oiliness, and hyperpigmentation occur.
