If the acne marks left on the face are mainly hyperpigmentation, you can use topical medications to lighten the hyperpigmentation, such as 0.1% retinoic acid cream, hydroquinone cream cream, levitra Vitamin C, tranexamic acid, or arbutin. It is also possible to achieve good results in removing blemishes through medical aesthetics, including microneedling, hydrafacial injections, fruit acid peels, and salicylic acid resurfacing. If the red marks are left behind, the best choice is IPL photorejuvenation to treat them, the effect is better. If you are left with sunken acne pits, you can choose CO2 fractional laser to treat them. All treatments are long term process, it is impossible to have good effect in short term, so patients need to cooperate well.
