Cos de BAHA Niacinamide 20 Serum 30ml Very effective serum for brightening and controlling oil. I noticed my pores looked smaller and my skin tone became more even after a couple of weeks. The texture is light and layers well with other skincare products. Excellent value for the price!
Still waiting Good product and good skin …………………….. love highly recommended
I know you can get a lot of Niacin in other products but great to get it as a stand alone product in 20% form
I’ve been using the Niacinamide 20% Serum consistently, and I’m very pleased with the results. It has helped improve the overall appearance of my skin, making it look brighter and more even-toned. I’ve also noticed that my pores appear smaller and my skin produces less excess oil throughout the day.
Amazing product I really love this over this range - recommended
