How to remove the Ance Scar From Face?

Main things: Don't pick at it and drink plenty of water.

Other things you can do...
skin lightning cream
honey (raw honey works the best)
baking soda paste (mix baking soda with water)
lemon juice
ice cube (even better is you just freeze green tea instead)

Any of those listed above work just by applying to the affected area. Some, you may have to leave on longer than others. For me, I just messed around with what felt comfortable.

I think fractional RF and CO2 fractional laser have a good treatment result for acne, you can go to a professional clinics or hospitals.
