I don't have enough physics knowledge to understand the possible difference between laser for hair removal, laser for scar removal and laser for tattoo removal.
I don't understand what is the essential difference between the three types of laser treatments, if at all there is one.
If there isn't such essential difference and although different marketing, all such machines have essentially the same laser:
- Doing laser treatment to remove hair from bad hair transplant on top of a scar might cause both hair removal and scar flattening
- Doing laser treatment to remove a tattoo on a scar (done to conceal scar) would cause both tattoo removal and scar removal; but I am not sure if all these laser methods are the same essentially.
What is the essential difference between laser for hair/scar/tattoo removal?
