As the saying goes, haste makes waste, and nothing can be immediate. The metabolic cycle of human skin is 28 days, and the physiological cycle of girls is 28 days, so no matter what products are used on the skin, it will take 28 days to see the effect. If someone has used it before, I suggest you find out the original solution they have used and make plans when you feel safe. If it is congenital freckles, I advise you not to throw it away. Only laser can remove freckles, and he will come back after a while, and the effect is obvious the day after tomorrow.
