Excellent Niacinamide Serum
This is a lovely Niacinamide Serum. I purchased it because I love Dr. Althea Skincare especially the 345 collection. This product is fabulous for hyperpigmentation, texture irregularities, post acne marks, balance sebum levels and minimizes pores. This is a 15% concentration of niacinamide. It works perfectly for my combination mature skin. However, if this is your first time trying niacinamide, I recommend doing a patch test. Niacinamide pairs beautifully with most ingredients including Tretinoin, Vitamin C, AHA/BHA, Peptides, etc. I have noticed my skin looks and feels better. My tone is more even and radiant.
