You can take the VC of Yangshengtang orally and use Olay whitening mask for external use. The effect of that mask is really good However, internal tuning is very important. These are protracted and long-term battles. Like you, I also recommend Guyuan ointment for regulating endocrine. The effect is immediate and the supplement is very comprehensive! My friend's skin changed immediately after eating it for three months! Great, I'm eating it now, too, because I haven't eaten it for two weeks, so I can't tell you the effect yet! I'll tell you when I have an effect!
