thank you.
I go on and off of it so its really hard to tell. I have ordered some collagen powder from Tibetan Yaks - no joke (trying to avoid chicken production for obvious reasons).

I never need to put creams on my skin at 47. I build it from underneath with fats and proteins like collagen. My wife who is still scared of fat and guilty about animal products, pours it on every night and her skin is still itchy and dry with lots of allergies. Though to be fair, she did get a lot of sun exposure when she was younger.

Have you tried?
