I am planning to use vitamin C serum in conjunction with my present skincare routine, which includes niacinamide and TRX acid for hyperpigmentation. I see the Goodal and Numbuzin serums at Korean skincare stores and hear that they are pretty good.
Is this true and are there any other good recommendations? Thank you!
Would love to see if it is effective
it does bit can be riskly if you have to go sun so be careful.
