Why use in the evening?

Retinol makes the skin more sensitive to UV radiation. For this reason, it is best applied in the evening, followed by a moisturizer. During the day, it is essential to use a broad-spectrum SPF, such as our High Protection Tinted Sunscreen, to protect the skin from sun damage and maintain the benefits of retinol.
