I have been using Skin Ceuticals Vitamin B Hydrating -Gel for years. I was first introduced to it by a well known dermatologist in New York City. It moisturizes my skin, keeping it moist and supple throughout the day. When I apply it I feel like I'm giving my skin a drink of water. Over the years I have been a consumer of many skin care products, sampling many different brands and items. However, I have always continued to use Skin Ceutical Vitamin B Hydrating Gel because of the way it makes my skin feel and look.
