This nighttime treatment formulation combines 0.5% pure retinol paired with antioxidants and a host of beneficial ingredients to hydrate and soothe, while minimizing the appearance of fine lines and wrinkles.

Directions:
In the evening, apply a pea-sized amount after cleansing and toning. Begin by limiting use to twice a week, gradually increasing application frequency to every other night, and then advancing to each evening or as tolerated. Follow with the appropriate PCA SKIN moisturizer. Mild irritation may initially be experienced and is not a sign of a negative complication. This product is indicated for use in the evening only. Daily broad spectrum sun protection is critical while using this product.
