Retinol 0.5

Apply a pea size amount in the evening to clean dry skin, avoiding the eye area.
Absorb product into skin before applying other skincare products.
Limit initial use to once or twice per week. Begin gradually increasing frequency to every other night, then every night as tolerated. Establish consistent skin tolerance before advancing to a higher concentration. Retinol may increase photosensitivity. Always use a high-protection, broad spectrum sunscreen when using this product.

As a precaution, products with retinol for skin should not be used by pregnant women or women who intend to become pregnant in the near future. Though there are no reports of topical retinol having any negative effect on fetal development, always consult a physician for your personalized needs.
