Apply HANSKIN Vitamin A Glow Retinol Cream in the evening on clean, dry skin, after your cleanser and toner. Start 2 to 3 times a week to let your skin get used to retinol, then increase the frequency if your skin tolerates it well. Use an amount equivalent to a small pea for the entire face, avoiding the eye and mouth areas. In the morning, always apply a sunscreen with at least SPF 30, which is essential when using retinol treatments.
