The Ordinary - skincareNerdie review for 100% L-Ascorbic Acid Powder

- Measurement is very complicated: definitely not for busy/lazy people. You need the right dose and also you have to mix it with the right serum. I used feuric acid with it. - I didn't see any major improvements, I had higher expectations from this product. Maybe not for me - You need to use the whole thing in 6months? Waste of product - In summary, it was a no for me..
