The effect of laser removing chloasma is still quite good after about 3-5 times, and the specific number of operations depends on the actual situation. If chloasma is older, the spots are more serious, or the spots are larger, it will take many times to remove chloasma by laser, which will have a good effect. If the skin is good and the spots are shallow, generally 2-3 times of laser to remove chloasma will have a good effect.
