Its okay. I haven't noticed any difference, but so far no negative effects, no breakout or peeling.

(R.S.G) Vitamin C
I just started using this serum not too long ago, definitely not for 3 weeks so I cannot comment on the claims that it diminishes your hyperpigmentation. But I wanted to comment on the formulation. The formulation is on the thicker side which is ok. It's important for me to put on vitamin C serum for the antioxidant aspect and I think it's doing a good job in that aspect. Smell is ok. Personally I don't smell much from it. This product is good so far. If there is a way to update I will to inform on how my hyperpigmentation is doing.

(R.S.G) Good product
Good product. I've only used it for a few weeks. Doesn't irritate my skin but also hasn't shown any brightening effects. Def need more time to show results
