Warning: Retinol 1.0 is only intended for those who already have experience with Retinol 0.5. Retinol 1.0 is a very high strength retinol product, and should only be used in the evening. To avoid irritating the skin, use a lipid-rich moisturiser such as Triple Lipid Restore 2:4:2 Anti Ageing Moisturiser after application of the 1.0 retinol to seal in moisture. SkinCeuticals recommends you consult a skincare professional before starting use of a product with this high a concentration of retinol. Retinol increases skin cell turnover and this process makes the skin extra sensitive to the effects of the sun. It’s essential to use a broad spectrum, high SPF sunscreen such as Skinceuticals Ultra Facial Defense SPF50 when using this retinol product.
In the evening, apply a pea size amount to clean dry skin, avoiding the eye area. Allow product to absorb before applying other skincare products. Limit initial use to once or twice a week, gradually increasing frequency to every other night, then every night as tolerated. It is recommended for new users to start with a Retinol 0.3 to establish skin tolerance. Retinol may increase photosensitivity. Always use a high-protection, broad spectrum sunscreen when using this product. As a precaution, retinol face creams 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.
