"Clinical studies show 2 to 5% is best, and more can cause irritation. [...] The Melasyl is a genuinely interesting molecule, but it's fragranced and there are really only two tyrosinase inhibitors in here, and we want a stack. It's the best fragranced option on the list and good for mild to moderate pigmentation if it were fragrance-free, but the way it is right now I can't really recommend it, and it costs £45."

"In contrast to the Mela B5 serum, this one has fragrance, which can be irritating, and remember, if anything causes irritation that's not good for the hyperpigmentation issue. It has resorcinol in it that can improve hyperpigmentation, niacinamide, and [...] ferulic acid, an antioxidant that may help improve hyperpigmentation [...] by reducing oxidative stress in the skin. It also has LHA, a modified form of salicylic acid, that helps precisely exfoliate the skin."
