i buy GNC ones..
2 boxes lasts for one month each box 91 bucks..
collagen content hihger than fancls..
but many pple take fancl cos e effect is faster..however once u
stop skin ocndition gets worse than b4...
some pple cant take collagen e.g high blood pressure,
consitpation, pop more pimples...so it may not be suitable for
all..
