With its ability to exfoliate the skin, leaving it smoother and brighter, glycolic acid is a staple in many skincare routines, but it can benefit your natural nails, too. In between BIAB appointments, I’ve often applied a glycolic acid toner to my nails and cuticles using a cotton swab, then followed with a glug of cuticle oil. The result? Fewer flakes and a stronger, smoother canvas for nail polish. If you’d rather not DIY, try the Dr. Dana Nail Renewal System, $30, a once-weekly, 3-step nail system that boasts glycolic acid, a nail primer, and a hydrating gel-oil to reveal healthy, hydrated, and shiny nails, fast. “It’s perfect for brittle, peeling, weak nails, post-gel damage, or if you simply want a gorgeous, healthy-looking shine without having to go to the salon,” says Dr. Dana.
