1. Dissolve vinegar and salt in water, and the ratio is about 9: 3:1. Wet the towel with the mixed solution and rub it on your face once in the morning and once in the evening (if you want to wipe it once or twice, it's no problem). Good effect, quick effect, skin whitening, acne disappearing. Rub it every 2~3 days. 3. Mix water and honey, then add pearl powder, so that after using it several times, your face will be white and tender! 4. The simplest, cheapest and most convenient whitening method (personal experience) Make bananas into a paste (it must be bananas, not bananas), then pour in whole milk and add a little water. The ratio of these things is about 2: 5: 1, then apply them to your face, then pat your face gently, and finally do nothing. Wash it off after 20 minutes ... what did you find! ! ! Is it a waste of time?
