should be treated by medicines. Garlic is irritant for skin,so it shold be avoided. However, you do not worry ,the black spots may go away by it self wthout treatment. Wait for two months. If the black spots do not fade, then kojic acid
and vitamin C
containing cream should be applied. And take oral vitamin C ,glutathion, and nicotinic acid for long time.. I hope you will get good result. And follow proper treatment for acne. Do not remain in stress and anxiety
. Avoid milk, ghee and excessive oily food to prevent acne..
