Geek & Gorgeous - btunde review for 101 APAD 20% Azelaic Acid Derivative Serum

Everything is good about it! Sooo good for removing my bumps, the redness, acnes. My skin is less oily since I use it. After first usage I saw it is more smooth and there are less acnes on it. I use it 3-4x a week in the evenings, I like its texture, it's basically water-like and very easy to apply on the whole skin - I also use the The Ordinary's Azelaic suspension for spot treatment only, it is hard to apply to the whole face. Try to combine with niacinamide, that will be a game changer if you have acne problems!
