In Your 40s
Your tennis game may be better than ever, but your skin is losing its "bounce." Blame hormones and the beginning of collagen degradation. Loading up on peptide-rich creams is essential — as is using hydrating cleansers. You may even want to take the plunge with Botox or injectable fillers. Makeup artists suggest shifting into neutrals (as bright colors call attention to wrinkles) and plumping up lips and brows with nonsurgical tricks.
Luxurious treatment creams: Splurge on vitamin-rich moisturizers.
MC recommends: Dove Pro-Age Neck and Chest Serum, $9.19; Clinique All About Eyes Rich, $27.50; L'Oréal Advanced Revita lift Lotion, $16.59.
Creamy cleanser: It's important to remove grime, of course, but opt for a hydrating cleanser to avoid stripping oils.
MC recommends: Dermalogica Essential Cleansing Solution, $28.50.
Hydrating facial blend: Creamy blushes and foundations soften lines and plump skin.
MC recommends: Sonia Kashuk Crème Blush Duo, $8.99; CoverGirl Advanced Radiance Foundation (it contains Olay lotion), $9.99.
Brow pencil and mascara: Both brows and lashes lose fullness after 40. Fatten them up with a chunky brow pencil and volumizing mascara.
MC recommends: Eliza's Eyes Brow Pencil, $20; CoverGirl VolumeExact Mascara, $6.99.
Lip plumper: Gravity is no friend to upper lips — they literally begin to invert in your 40s! Add definition with a nude pencil, then fill out the silhouette with a plumping gloss.
