I have always been black, and I will try it myself when I get it.
You must read the instructions before you get something: (I got it from Yu)
effective constituent
L- cysteine 240 mg, ascorbic acid (vitamin C)300 mg, pyridoxine tartrate (vitamin B6)6 mg and calcium pantothenate 24 mg.
The main preparation is vitamin C, which consists of 240 mg of L- cysteine.
use
Take two capsules orally before or after meals, three times a day.
From the composition and description, there are no side effects. VC can resist oxidation and reduce pigmentation. To put it bluntly, it is to inhibit your blackening, promote metabolism and accelerate whitening. The darker the person, the better the effect.
And it is specially marked that pregnant women, lactating women and the elderly can use it badly!
Vitamin C can inhibit melanin production, promote skin metabolism and relieve pigmentation caused by spots and freckles.
Ok, I'll write a post-use evaluation after I go back and try it!
