SkinCeuticals - Tolly review for H.A. (Hyaluronic Acid) Intensifier Serum

SKINCEUTICALS H.A. INTENSIFIER CORRECT 4ML. Multi-Functional Serum to help amplify skin's Hyaluronic acid levels. I received this product as a free sample from SkinCeuticals. The serum is a small bottle of 4ml and is very effective on my skin. I use it for both my am and pm routine and I always feel the hydrating component on my skin for the whole day. It smoothens my face, and it does not irritate my skin.
