Hyaluronic Acid 0.3% is for you if you are looking for hydration, and for that hydration to be deep and last. It contains hyaluronic acid molecules of different sizes, which is why the hydration is so powerful and your skin feels "plump." Like all the products in the range Pai Labs it is a concentrate that gives extra intensity to the routine.
How to combine it? It can be used as a single serum, together with another or mixed with the moisturizer. We like to combine it with C-2 Believe, the moisturizer with vitamin C for sensitive skin, and with Resurrection Girl, the hydrating and refreshing mask. Cleanse your face, apply the mask, this serum and C-2 Believe, in that order.
