Laser hair removal affects skin pigmentation for a long time, which can last forever. Indeed, laser hair removal works by targeting hair follicles via concentrated light energy. This energy penetrates heat with precision into follicles, which leads to their destruction and hence prevents their regrowth. Though this painless laser hair removal treatment is safe and effective, it can cause pigmentation. However, it does not last longer.
Considering how it works, let’s explain it. The laser targets melanin, which is the pigment providing colour to hair and skin. In some cases, the very same laser leads to hyperpigmentation (or skin darkening) or hypopigmentation (lightening skin tone) where it is treated. Source (webmd.com)
But these changes occur in those who have darker skin tones or who expose themselves to the sun before and after the laser hair removal treatment. The noteworthy point is that pigmentation shifts or changes are temporary. It balances over time as the skin continues to regenerate its cells. This risk can be significantly reduced by using the compatible laser type as per your skin tone. Also, pre- and post-treatment care can also make a huge difference.
Permanent pigmentation is rarely seen. It is usually associated with improper laser settings or unqualified practitioners. A certified dermatologist or licensed laser technician can ensure safe treatment. He or she has practical knowledge of removing hair to deliver smooth and lasting results without impacting it permanently.
