If I'm concerned about lines, when should I start an anti-wrinkle regimen?
"A retinol is great to start, at about the age of 25," says Dr. Russak. Retinol will help accelerate cell turnover. For best results, consider adding vitamin C, an antioxidant that fights free radicals, so it helps your retinol do a better job. "Not only will such a regimen prevent excessive sun damage, but it will provide chronic hydration and evening of the epidermal skin layer," says Dr. Jegasothy. (Also, be mindful of these skin products that can secretly damage your face.)
When should I use a full body scrub?
In the same way your face needs help shedding dead skin cells to make space for new ones, so too does the skin on the rest of your body. Instead of just exfoliating your face, be sure to also treat your arms, legs, chest, belly, and beyond. "Full body exfoliation is great from the mid-20s on, simply because it eliminates dead skin buildup," Dr. Jegasothy says.
Just don't do a head-to-toe scrub too often. Dr. Russak says that "skin will take up to 20 to 40 days to renew itself once you're past your teenage years." So, there's no need to exfoliate your body more than once a week.
