Review (5/5): My skin and hair love this stuff.
I had my doubts but I have to say that a month of Yana had my skin glowing. Also - when I went to salon for a haircut - my stylist asked what I had been “taking” as she said my hair was quite a bit thicker. (And she’s been doing my hair for a long time). I had tried other collagen supplements previously and they made me break out...but Yana has given me no adverse effects.
