It is a highly effective mattifying sunscreen, specially formulated for acne-prone skin. Protects against UV rays, while reinforcing the skin’s defenses against harmful UVA rays on a cellular level. The Glutamic acid contained in this non-oily formula regulates sebum production and removes shine due to the mattifying powders. Because acne-prone skin needs more than a simple sunscreen, A-Derma developed an innovative sun care filter, the Barriestolide®, derived from the Rhealba® Oat Plantlet Oil, strengths the skin’s defense barrier. With only 4 filters, this product is perfect for highly sensitive acne-prone skin types.
