Will laser hair removal treatments cause skin damage after a while? e.g., open pores, lines, dryness, fat loss, sagging?

Laser hair removal targets pigment and has not been shown to cause lines, wrinkles, or enlarged pores. Laser devices are frequently used to help address those concerns in the skin. However, complications can occur if you are treated by someone who is not well-trained or uses an incorrect device, so it is much more about finding an expert to treat you.  I hope this helps.
