In Your 40s
The wrinkle-fighting retinoids you may be using now can dry out your skin. If you're not getting enough hydration from a combo anti-aging and moisturizing formula, says L.A. dermatologist Ava Shamban, add in a hyaluronic-acid serum after cleansing and exfoliating but before anti-aging products. If your skin is still dry, use another moisturizer with antioxidants after the serum.
