سيروم ألترا بيور هاي بوتينسي 5% حمض نياسيناميد

Unremarkable but not terrible

My dermatologist recommended I use niacinamide to help reduce redness, and I've been using The Ordinary's 10% formulation for years which works pretty well. I decided to give Kiehl's version a try because I read online that 5% is actually a better formulation since too much niacinamide is bad for the skin and it's included in many products (including my lotion). This product is OK. It's a much more runny and stickier formulation than The Ordinary's. The instructions say to use 4-5 drops; honest, I think 3 is more than enough unless you have 5-10 minutes in the morning to wait for this to absorb. After 2 months, I haven't noticed a real difference to my skin. After I finish up this bottle, I'm going back to The Ordinary seeing as it does the same thing for a much lower price.
