azelaic acid works best if u have a bit of melanin in ur system

[FiendFiend]

i was pasty white asf, i hopped on mt2, and i realised my azelaic acid started working out of no where to clear acne marks, i think azelaic acid doesnt wanna whiten ur skin if u got no melanin and are super white as it is. but when theres some melanin in the equation it starts working.
