I have thoroughly tried four more serums from The Ordinary, and these are all under the $10 mark. Two are definite favorites from The Ordinary line, and two were somewhat disappointing. I love the low price point, which allows me to try lots of new active ingredients for the first time and see how they work for my skin, and I also really enjoy that the Ordinary’s products often have very no-nonsense ingredients. This time around I will be reviewing the Alpha Lipoic Acid 5%, Granactive Retinoid 2% in Squalane, Niacinamide 10% + Zinc 1%, and Resveratrol 3% + Ferulic Acid 3%.
