RoC Multi Correxion Revive + Glow Daily Serum is a dermatologist-developed vitamin C serum for face that boosts luminosity and helps improve elasticity for visibly more radiant, firmer-looking skin. Each 1 oz / 30 mL bottle features a patent-pending 10% Active Vitamin C blend with Nonapeptide (a firming peptide), plus antioxidants and advanced hydrators to help defend skin from oxidative stress caused by daily pollution. The lightweight, fast-absorbing texture layers comfortably under moisturizer and makeup to help refresh the look of dullness and uneven tone, without a greasy feel. In a clinical study, results were seen quickly: in minutes, 94% had improved luminosity & elasticity; in 1 week, 97% had visibly improved skin texture; and in 4 weeks, 100% had visibly brighter, tighter skin. The formula is dermatologist-tested, clinically proven, non-comedogenic, paraben-free, and formulated without lactose. RoC is PETA-approved and cruelty free. Vitamin C can feel tingly when you’re new to it, especially if your skin is very sensitive. For best comfort, patch test first and start once daily or every other day, avoiding the eye area and broken or recently exfoliated skin. If you experience severe burning, swelling, or persistent redness, rinse off and discontinue use. Use AM and/or PM after cleansing: smooth 4–6 drops over face and neck in upward strokes, then follow with moisturizer. Always apply a broad-spectrum sunscreen SPF 15+ during the day while using this serum. With consistent AM+PM use, this bottle is designed to last about 1–2 months. For even brighter skin and 24HR hydration, pair with RoC Multi Correxion Revive + Glow Gel Cream.
