When and how often should I use Retinol?Updated 2 months ago

Here are our top Retinol recommendations:

• Only apply Retinol products during your evening routine.
• Weekly Retinol use should increase with age. In your 20s: apply Retinol twice a week. In your 30s: apply Retinol three times a week. And so on for each additional decade. 
• Only use one product containing Retinol on any given day. 
• Always wear SPF during the day when using products containing Retinol.
• Monitor any skin sensitivity and adjust product use accordingly.
