I tried it with my mother's VE, and the acne scar subsided a lot in only 3 days.
You can also let him try. I use the natural VE of Yangshengtang. One bottle 160 60 yuan.
Take a stick, squeeze it out and apply it to the acne scar, and gently massage until the skin is slightly hot. Once in the morning and once in the evening, it absorbs oil as soon as it is applied.
Within half a month, there will be amazing results.
