Cristina Carlino, founder of Philosophy skin care, used to compare using the Philosophy Turbo Booster C Powder to yoga and the Philosophy Help He retinol treatment to cardio. I’ve always loved this comparison. I’ve adopted it and expanded it to help my clients understand how to balance their routines with just enough work and rest for your skin.
Retinoids (retinol serums, prescription Retin-A) and AHA peels are like a strength training routine. You can’t work the same muscles every day. You have to take rest days to allow time for muscles to rebuild. You’ll weaken the skin if you use a retinoid every day, just like you’d weaken your bicep and cause yourself an injury if you worked it out every day. You have to have rest days so you can build back stronger and better.
I generally advocate limited usage of AHAs and retinoids for this reason. I like to take time off from these ingredients now and then, or use them just a few times a week. This way, you allow your skin to rebuild on the off days, thus strengthening your skin.
I love ingredients like vitamin C to repair and restore, but you can use anything designed to be anti-inflammatory on your days off. Just as you might take a restorative yoga class after a tough workout or get a massage after a long run, try something designed to reduce redness or calm irritation.
This method of rotating products can make your skin care routine feel complicated, but it doesn’t have to be. You can still use a simple three-step routine; just swap your products on designated nights. Stick with a schedule so that you don’t have to think about it. It takes a while to build the habit, but with a little practice, you’ll have it. And your skin will thank you for it later!
