What the gurus are saying

This serum tackles hyperpigmentation through multiple pathways, glycolic acid and lipo hydroxy acid exfoliate while tranexamic acid and kojic acid target melanin directly, and gurus praise the results on dark spots and skin evenness. The one thing to keep in mind: it can irritate sensitive skin, so those new to actives may want to patch-test first and ease in slowly. At forty dollars a bottle, a little goes a long way, just a few drops cover the face.

"This is one that I use myself and recommend to patients. It's [...] geared towards those that struggle with hyperpigmentation and [...] post acne marks, [...] as well as melasma. [...] This has been clinically proven to help reduce dark spots and post acne marks and also [...] helps to improve skin clarity and evenness. [...] It contains niacinamide and a patented ingredient called melasil that helps to target the melanin pathway, which is unique to La Roche-Posay, and then lipo hydroxy acid which is a more gentle acid that helps to exfoliate, remove dullness and uneven skin tone, along with thermal spring water. This is a lightweight serum that absorbs pretty quickly."

"La Roche-Posay has reformulated their Mela B5 pigment control product and it's quite good. It's got glycolic acid which can help exfoliate the skin and improve the rate of clearance of hyperpigmentation, it has tranexamic acid and kojic acid, and both of those are great for hyperpigmentation. It also has lipohydroxy acid, a modified form of salicylic acid, that exfoliates the skin a bit more precisely. This product may be irritating, and if it causes you too much irritation it's not worth pushing forward with it just for the sake of using it. It's not inexpensive at forty dollars, that's pretty pricey, but you don't need a lot of it, just a few drops spread on the skin well to create a thin film."
