Advanced Renewal Serum

A nighttime Vitamin A serum with retinaldehyde and niacinamide that supports cellular renewal and helps improve visible signs of aging, uneven tone and texture. 1 fl oz / 30 ml.
Best for: All skin types when appropriate · Breakout-prone skin · Texture and tone concerns
Key ingredients: Retinal (Retinaldehyde), a stable Vitamin A technology supporting cellular renewal, smoother texture and a more even-looking tone. 5% Niacinamide to support barrier function, lipid synthesis, even-looking pigmentation and calmer skin. L-Carnitine to support cellular energy processes and skin turnover while helping limit water loss. Phenylethyl Resorcinol, an antioxidant and tyrosinase-inhibiting brightener. Bisabolol, a soothing ingredient that helps reduce visible irritation.
How to use: PM only. Acclimate gradually — dry skin, begin 1–2 nights weekly for a couple of weeks then increase as tolerated; normal/combination, begin 2–3 nights weekly; oily skin that is not dehydrated, begin 3–4 nights weekly. Follow with moisturizer. Daily morning SPF is required.
Do not rush retinoid acclimation. Increase frequency based on tolerance and barrier condition.
