How does laser remove melanin do?

Melanin may be the pigment that gives hair color. You'd expect melanin to absorb the energy of the green laser pointer and then blend the heat into the hair follicles. The heat actually kills the hair follicles, which can't be regrown. In addition, people with dark skin have more melanin, which is necessary to ensure the process is still carried out efficiently. To help with this, cold compresses are often used to guide the area to cool down. The laser will not be aimed at cold regions that are important to the results. 445nm, single photon energy is very high, so as power, short distance combustion is best, but the longer the distance the burning power decreases, but as the output increases, the longer distance combustion effect gradually catches up with the low green power. The HTPOW Blue 20000mW laser Pointer is a high power laser pointer designed to look like a Gatling gun. The 20,000 MW burning laser is powerful enough to light a cigarette or paper, and it's also an astronomical laser pointer that will help you study astronomy. Once you have it, you will find it very useful in your daily life!
