I’m Turning 40, and I Don’t Want to Age Naturally

Peach & Lily Retinal For All Renewing Serum ($55)

After multiple attempts to incorporate retinol into my routine, I finally found one last year that doesn't irritate my super-sensitive skin. This patent-pending formula pairs 0.1 percent encapsulated retinal — the most potent retinoid available without a prescription — with soothing ingredients for clinical-level results without the irritation. Since using it three nights a week (spaced throughout the week), I've noticed a major improvement in my skin's texture and brightness.
