生物素+膠原蛋白美容滴劑 柑橘綜合風味，2液量盎司（59毫升）液體

The dropper makes it effortless to add to my morning water, and the citrus fusion flavor actually masks the collagen taste pretty well. I’ve been using it for three weeks and my nails feel noticeably stronger, which is exactly what I hoped for.

The dropper makes it easy to measure out exactly what I need, and the citrus fusion flavor is surprisingly pleasant—no weird aftertaste like some liquid supplements. A little goes a long way, so this small bottle should last me a while.

I've been adding these drops to my morning water for about three weeks now, and the 2 fl oz bottle still has plenty left — a little goes a long way. The citrus fusion taste is subtle enough that it doesn't ruin my coffee afterward, which is a win.
