    Love it

    Big fan of this serum, its noticeable when I haven't used it, my skin doesn't feel as fresh or clear. Must have in a routine. It's slightly thicker than other products, however I'd still use it right after HA to really soak up the benefits

    Niacinamide Serum

    This niacinamide Serum is very effective for my post acne oily skin. It absorbs fast on the dump skin and also is a good combination with other products. I use it more than 2 years.
