膠原美肌?

護膚品公司聲稱膠原蛋白飲料有助肌膚保持彈滑。
Cosmetic company states that collagen drink can keep our skin elastic and smooth.
然而，膠原蛋白會在胃部分解為不同的氨基酸。
However, collagen is broken down into different amino acids in stomach.
問題在於膠原蛋白是由什麼不同的氨基酸組成?
The question is that what kinds of amino acids does collagen compose of ?
其實，肉類(如魚肉)已含有優質的蛋白質，豐富的氨基酸。
In fact, meat like fish has rich protein and plenty of amino acids already.
那麼喝膠原蛋白飲料、吃肉類和食燕窩有何分別?
What is the difference in taking collagen, meat or bird net?
如果膠原蛋白飲料有神奇功效，還有人買燕窩嗎?
Will anyone buy bird net if collagen drink has magic function?
最後順帶一提，你相信膠原蛋白(這樣一個大份子)可塗在臉上然後穿透入肌膚嗎?
Lastly, do you believe that collagen can penetrate the dead skin and make skin better?
