Nava Md is a great company. The tretinoin cream I got seems great too. It feels very smooth n goes on nicely. U only need a small amount to cover ur whole face. Unfortunately for me, I've only been able to use it a few times bc I think I had a bad reaction to it. Some more sensitive parts of my face turned red, and sting if I put anything on it, even just a moisturizer. Also, my skin has started peeling around my eyes, on my forehead and on my nose.
