What it is: Perfecting Neck & Décolleté, $75What it does: Improves firmness of the neck area, reduces fine lines and wrinkles while also nixing redness and hyperpigmentation.Why it works: Now that summer’s over, it’s time for some serious skin rehab. If you weren’t religiously appling sunscreen daily (don’t tell us, we don’t want to know), chances are you did a bit of damage. And while our faces might seem like the most important parts of our bodies, the thin skin on your neck needs some TLC, too. After all, turkey neck is one of those signs of aging you’d like to stave off as long as humanly possible, right?The peptide combinations (palmitoyl tripeptide-38 and 5) in this formula boost protein and collagen formation in the skin, which strengthens it and increases elasticity to prevent sagging and wrinkling. Another key ingredient, calcium hydroxymethionine, has shown to seriously improve the delicate skin on the neck and chest. “It is particularly suited to treat this skin due to its ability to dramatically increase keratinocyte [skin cells in the outermost layer of skin] proliferation and collagen stimulation, and improve the elasticity of the skin while reducing the appearance of crêpe paper-type skin,” notes Jennifer Linder, M.D., board-certified dermatologist and chief scientific officer at PCA Skin.Niacinamide helps correct color, minimizing hyperpigmentation and reducing redness. And a small amount of everyone’s favorite anti-ager, retinol, also helps clear the skin and even out skintone.Why you care: Fifty-nine percent of YouBeauty readers either don’t wear sunscreen daily or wear it but only on their face. This cream will help strengthen and repair the damage done to this sensitive spot without irritating it. (Note: This should not replace a daily sunscreen. You should still be slathering it on every day if you’re serious about preventing old lady cleavage.)MORE: A Controversial Injectable That Cures Double Chin
