Long time fan of this amazing Vitamin C
I started using this product around 2018 and I think that making it a staple in my routine has been one of the best decisions I have made in my skincare journey. I have tried (out of mere curiosity) other Vitamin C serums, and I actually noticed my skin moving in the wrong direction (dull, melasma, discoloration), after returning to this I saw the brilliance return. This product does not break me out and has a very slight citrusy smell that is delightful and fades quickly. Also, it LASTS. Typically one bottle of this can last me over 6 months. Highly recommend!
