Review (5/5): My secret weapon
I just bought it, again. My last bottle lasted six years, the one before... I can't remember.
I can say: I am 69, but my skin is nearly wrinkle free. My mother's skin was like a prune... And all because of this Donell AHA.
I use it only after a shower... except when I have to get on camera: then I even apply it to dry skin, and it makes me look ten years younger... or if not younger, then NOT TIRED... which is, in my case, quite an accomplishment, working 16 hour days in front of the computer.
