Correct Usage and Precautions (Very Important):

1. Evening Use Only: Retinol should be used at night only, and never applied during the day.

2. Wash your face thoroughly with a gentle cleanser, then apply toner and wait until your skin is completely dry (applying retinol to damp skin may increase irritation).

3. Apply a very small amount (pea-sized) to your fingertips, and gently spread it over your entire face and neck, avoiding the eye and lip areas completely.

4. Wait a few minutes for it to absorb into the skin, then follow with a rich and nourishing moisturizing cream (such as ceramide cream) to soothe the skin and lock in moisture.

Gradual Use and Protection Tips:

• Gradual Use: For the first two weeks, use it only two to three times a week until your skin gets used to it, then you can gradually increase the frequency to daily, depending on your skin's tolerance.

• Sunscreen Commitment: On the morning after use, it is absolutely essential to apply a high-protection sunscreen ($SPF50+$), as retinol increases skin sensitivity to light and sun.
