Lasers are very well employed in hardening of surfaces without wearing out or tearing a surface. This hardening provides a coating that is waterproof and strong.
- Removal of Strech Marks
In the beauty industry, stretch marks are a big bother to ladies and their removal in painstaking. Using laser technology, the process of getting rid of stretch marks is easy and consumes minimal time.
