Niacinamide 10% + Zinc 1% Serum for Face - Pore Reducer + USA Skin Care (30ml)

I love this skincare product😍😍

Lo mejor de lo mejor para el cuidado de tu cara. Este producto es excelente, fue crucial para eliminar y mejorar el acné en mi cara.

Me gustó mucho y la cara. Se le ve los cambios, se los recomiendo

I've used this product for a couple of years now. It's very good and does a great job keeping my skin clear and, I feel like it makes it brighter also. I'm not sure I've seen much help with dark spots, but that's not why I use it. I'm not positive but I believe it does contain some hyaluronic acid as well. In any case, I like it a lot but do have to cycle it and not use it every day because it is occasionally a bit irritating. I assume this is because the niacinamide concentration is higher than necessary to obtain clinical results, but I'm not a doctor. I just know it stings a little sometimes, especially when my skin is sensitized.

Perfect

At least $4-5 cheaper that bigger beauty retails store . I absolutely love this product just wish I had started using it sooner . Make sure to wear moisturizer with sunscreen after application, my skin didn’t very sensitive but it could potentially cause redness if in the skin too long with out sunscreen .will be buying again!

This helps my skin so much!!

Apart from the dropper not working, I could not tell any difference from using this product. So, neither recommend or discourage anyone from using this product
