I switched over to Kinohimitsu's Collagen Diamond after recommendations and also I find my usual collagen drink (from my beauty salon) a tad too expensive. The drink is not too sweet and has a pleasant taste. I haven't seen any difference, sorry - maybe I am drinking collagen drink most of the time. But my mother-in-law is raving about the product. She once scrapped the skin off on her forearm when the lift door closed on her, and the broken skin recovers slowly, probably due to her age and also she doesn't use body lotions and oils. After drinking daily for a week, she was pleased with the growth of her skin. And I just bought 6 months' supply for standby. Thanks for a great product - I will make it my regular beauty regime.
