This is how the powder looks before and after... usually I just put it into a cup of room-temperature water (I don't use warm water because I don't know if the heat will render the ingredients inactive) and it takes a lot of stirring to make it dissolve, which is a pain. It tastes nice and sweet with a berry taste, but the first few times I could taste the aftertaste of marine collagen which could not be covered by the berry flavoring. After about a week though, the taste grew on me and I find it pretty palatable.
I've been taking one satchet almost every night before bedtime (almost, because sometimes I'm too tired and just want to go to bed), and after 1 week I notice I wake up with brighter, smoother skin which is generally calmer (smaller pore size, zits are less inflamed). I suffer from poor blood circulation which causes skin discolouration, but this supplement seems to have evened out my skintone so that I wake up with more radiant skin. I can't say anything about improvements to fine lines and wrinkles though, because I'm not in that age category. :P
As for the frequency of consumption, I think it's fine taking it once daily, because it's expensive to take it more frequently (S$74.50 for 30 satchets is pretty expensive to me, it's like US$55 a month) and I've heard horror stories of other people overdosing on collagen supplements leading to adverse health effects.
