e.l.f. Blemish Control Face Primer is a makeup primer formulated specifically for acne-prone and blemish-prone skin. It's infused with salicylic acid, tea tree oil, and vitamin E to help clarify skin and calm the look of breakouts while it preps skin for makeup application. The lightweight formula sets to a sheer matte finish, smoothing and gripping makeup so it lasts longer, while still delivering soothing and hydrating benefits so skin doesn't feel stripped. It's a good pick for oily or blemish-prone skin types wanting a primer that does double duty as a light treatment step. Apply a small amount to clean skin, blend evenly, and let it set for about 30 seconds before applying foundation. Vegan and cruelty-free.
