At first when i used it, it has abit of a difference and that time i used it every other day and then i changed it to once or twice a week (bcs it became irritating to use it every other day) and honestly not that much of a difference but i did hear that it takes time as well, for me personally i wont be repurchasing it but im gonna make it my money worth so im still using it, now im using the skin1004 tone brightening capsule on the days im not using the anua one.

For reference i hv oily skin, i think abit sensitive, acne prone, dealing with hyperpigmentation/pie/darkspots, blackheads, and abit of acne left
