Niacinamide

Very nice product, have been using this for a few months and feel the texture in my skin improve. Small bottle, but it will last a very long time. I usually only use it in the evening after my hydrating serum and before my moisturizer. Costs below 10 euros, so definitely a hit.

Super fine serum, and the price is great! If the inkey list used other bottles, I would be sold 100%. But the content is amazing!

One word: great! I use this product twice a day for hyperpigmentation and acne scars. Does not sting and feels very nice on the skin. Also absorbs quickly and therefore doesn't feel sticky either. Overall super fine product. Important is to use consistently before you see real results. 1 disadvantage is the packaging, the cap from which the serum comes out gets dirty quickly. So often have to clean it properly...
