I have been using this product for many years since there is NO other collagen gel for the skin on the market.
Twinlab used to carry a fabulous elastin collagen gel but they discontinued it).
Many products 'say' they contain collagen, but actually very little. I use it before my moisturizer
and sometimes when I wake up w/ swollen eyelids.
Really doesn't need red colouring though ! In Mexico you can go into a pharmacy and buy liquid pure collagen .
Robert's may be the best we can get in the U.S.
