cupiegrand: What's your feeling about aqua-collagen-gel? Is it good? And how about the other products in the testing set?
The Aqua-collagen-gel is pretty normal and neutral... don't know it's effectiveness yet. But one good thing is the simplization of steps... you can apply the gel right after washing.. isn't it simple and save time?! The cleansing gel and washing foam is okay.... normal and neutral. I even didn't see the effectiveness of Twin White Stick.. probably need sometime before it works.... hope it really works.
