Laser whitening underarms is one of the most effective treatments for hyperpigmentation in that area, regardless of the cause. 

The first-line treatments for dark underarms are usually creams, serums and other topical treatments.

When these fail, many people turn to laser treatment. 

How Lasers Whiten Underarms

The laser energy breaks down the melanin (darker pigment), which is subsequently taken away by your body’s healing response.

Laser treatments work on the principles of selective photo-thermolysis.
