Hello, please help share research. that the members refer to as well

I'm just wondering here. is that the recommended rate is to be a % suitable for the skin Or something good for absorbing the skin like this? Like Madecassoside should use 0.2-2%. But I recommend 1% means that this 1% is good for the skin or will it work the best or is there another reason?
