Do I put retinol on before or after moisturizer?Updated a year ago
You should apply retinol before your moisturizer. Once you've applied retinol, wait about 30 minutes for it to fully absorb into your skin. Then, you can moisturize!
That said, you can also intentionally dilute the retinol to minimize chances of irritation. This is called “sandwiching,” where you apply moisturizer both before and after. This slows the rate of penetration, but remember that it’ll also reduce efficacy.
