    Great serum

    Bought for my 13 year old son as part of his skincare routine as he suffers from acne, especially on his forehead. He uses it morning and night and helps brighten and fade acne scars.

    Works Really well

    Minimises pores and keeps them clean. Absorbs nicely!

    Niacinamide Serum

    Thick consistency, feels a bit too tacky and I’m unsure if the the product is helping just on its own. However this along with the vitamin c have definitely improved my skin concerns: dark spots, dullness!
