The Ordinary Amino Acids Reviews by the Deciem Addicts
I love The Ordinary Amino Acids. I bought this one a few weeks ago. I’m 36 male with combo skin. This is super, super moisturizing and very efficient. I only need 4 drops for my whole face and neck (but I have a beard, so u might need more).
One of my favourite products 🙂
I wanted to love The Ordinary Amino Acids, but I get hives and reddened skin.
Amino Acids is greatly used as an add-on in your normal routine when you need an extra boost of hydration.
I like Amino Acids. I am using tretinoin, and it is part of my hydration routine.
Love it!
Amino Acids deserves the love that the Hyaluronic serum gets.
