Start slow: If you’re new to retinol, use this serum 2-3 times per week and gradually increase as your skin builds tolerance.
Use at night: Retinol can increase your skin’s sensitivity to the sun, so apply this serum in the evening and follow up with a broad-spectrum sunscreen during the day.
Hydrate: Make sure to follow with a moisturizer to lock in all the hydration and help combat any dryness that retinol might cause
