I have had a bunch of them in my time,all the lasering stuff is over rated and overly expensive. cheapest is obv doing it yourself,but leaves a slight portion of it remaining
Buy wart remover,cost me 70 baht when purchased months ago,two or three applications and the thing drops off,leaving no trace
2500 baht for ONE tag??!! Do you mean it was actually IN your eyeball? Maybe they charge by time/session so if you have 50 tags, you get a wholesale deal. I think using pros is better for this kind of thing. Scarring is possible and I would imagine professionals know the better ways to avoid this.
