It doesn't take a fancy formula to adequately moisturize your face. A simple daily facial moisturizer plumps up otherwise dry skin cells to help erase fine lines and smooth your skin's overall texture. Dermatologists have also found that certain vitamins and antioxidants may stimulate collagen production in order to maintain elasticity in the skin and promote skin cell repair.
Among nonprescription additives, the vitamin A compound retinol has shown the most promise for temporary wrinkle reduction. Synthetic hydroxy acids are commonly found in moisturizers as well; they're meant to exfoliate dead skin cells and trigger new skin cell growth [source: Mayo Clinic]. Soy compounds may even out skin tone and build collagen fibers that give skin its smooth texture. Vitamin C is also thought encourage collagen production, although it doesn't interact well with vitamin A (which retinol is derived from).
