Why Brown Skin Responds Differently to Brightening Ingredients
Brown skin produces melanin more readily than lighter skin tones, which is its protection against UV damage. That same responsiveness is also why post-inflammatory hyperpigmentation, the dark mark left behind after a pimple, a cut, or even a wax, tends to be deeper, more stubborn, and slower to fade. Ingredients that interrupt melanin production at the wrong stage, or that cause irritation in the process, can trigger more pigmentation rather than less. This is the first thing worth understanding before choosing between kojic acid and alpha arbutin: both work by slowing down the enzyme tyrosinase, which drives melanin synthesis, but they do so differently, and the difference matters for darker skin tones.
