“This serum is absolutely gorgeous! It's beautifully silky, glides over, then just melts into the skin. This is the best hyaluronic serum I have used. It plumps and hydrates the skin, and gives a lovely glow. I use this under the C Serum and the two products together are magnificent. This combination is great to use in the morning and gives the skin a gorgeous healthy glow without makeup. The pink hue of this serum is so unique and makes it more joyful to use. I will continue to purchase this serum and highly recommend using Hyalavive underneath the Effica C Serum. I was pleasantly surprised with the glow this combination gave my skin.”
