Anti-Aging Vit C Serum is total and complete hydration for the face, neck, and de’colletage. It has a high content of Vit C micro powder content so you will possibly feel a tingle until you get used to it. I recommend using it in conjunction with the Microdermabrasion Paste for better results. You will definitely feel a tingle if used this way. The paste removes the top layer of your skin so that the serum can get into the cells to do what it was created to do….hydrate the skin, smooth the fine lines and wrinkles, along with balancing the skin tone decreasing sun spots with the unwanted signs of aging. This serum will increase blood flow to the surface of the skin for rapid cell turnover. It can be used twice a day if your skin is extremely thirsty, dry, or dehydrated. I personally use it at night before I go to bed but when I travel to dryer states such as Texas, I require it in the morning and at night. I also have a T Zone so I do not apply it in that area where I am already oily. Believing she is beautiful is important. Taking care of your skin at any age is a must.
