Serum is a skincare product that delivers powerful ingredients directly into the skin. It is made up of smaller molecules that can penetrate deeply into the skin and deliver a very high concentration of active ingredients. If you are starting to feel the aches that comes with age then it is probably time to consider the implications when it comes to skin care as well. The facial serum is no “polyjuice potion” but it is great at targeting a specific concern. Like wrinkles(not the aches unfortunately).
