The Retinol Serum is an overnight product. It can be used every two nights in the evening routine or three times a week (alternating with a moisture-focused routine). The frequency of use can be increased as the skin becomes accustomed to this concentrated formula.

For sensitive skin, the serum should not be used in the same routine as products based on acids or enzymes until compatibility with the skin is assured.
