Comparing Vitamin C Derivatives 🍊 Best Brightening Vitamin C Serums for Sensitive Skin
"I really enjoyed the other discoloration uh product as well as their pot and C serum they're both lovely but currently the price of their pot and C serum is upwards of $100 or actually more than that so I just don't think you need to spend a 100 bucks on anything"

Peter Thomas Roth New! Potent-C™ Niacinamide Discoloration Treatment Review, How to Use, Dupes
"For what this product promises, intensive brightening treatment to help improve the look of discoloration, dark spots, and post-acne marks, I would agree that it does help with everything it promises. It also offers some nice hydration and works well over ascorbic acid serums. [...] That being said, this one struggles to really fade my melasma much. [...] I find most brightening ingredients really don't touch it because it's just such a stubborn, strong form of hyperpigmentation. [...] If you have newer forms of hyperpigmentation, sunspots, or post-acne hyperpigmentation, this may help with that, but for very stubborn, long-lasting hyperpigmentation, it just maybe helped a little bit but it's never going away totally. [...] This is friendly for most skin types: sensitive skin, dry skin, oily skin."
