How we score →Yay
5 experts · Moderate agreementWhat the gurus are saying
Tranexamic acid and arbutin do the brightening work here, and the experts describe a gentle, well-balanced formula that suits sensitive skin. It sits on the pricier side, but the ingredients are kept at effective levels rather than crowded in. One bottle turned dark and spoiled early, and a dark color is generally a warning sign, so those with sensitive skin may want to start with it.
