Welcome to HealthcareMagic forum,
We often come across such patients who gets these marks following waxing.These marks are very stubborn and take very long to go in-spit of the treatment .There are times when we see a ingrown hair underneath ,but at times there is folliculitis
(infection of root of hair) leading to black bump and mark.
If at all you see underneath in grown hair then the only remedy is to extract the hair out.This would be a time taking procedure ,in-stead you can go in for laser
hair reduction.Lasers give excellent result in ingrown hair.
If it is just the folliculitis then you can apply any cream containing mild steroid
and antibacterial agent.
Finally the best solution would be a laser.
