The DR’s Pick: Skinmedica TNS Essential SerumEssential Serum from SkinMedica is one of the more powerful, effective skin care products available on the market today. Period. There is no other single product that reverses the signs of aging skin as effectively. The high concentration of growth factors in the serum promote visible improvements in roughness, fine lines, coarse wrinkles, and elasticity after only three month of use. It hydrates the skin, protects it from UV radiation (sun) and free radical damage, and minimizes age spots. After evaluating the science and results behind Essential Serum, I firmly believe it should be a required part of every patients skin care program. The results speak for themselves.
