Why does the home hair growth instrument use 5mW laser energy? What about the peninsula?

At present, 5mW is the most favorable laser intensity to activate the root of hair follicle. Exceeding this intensity may cause irreversible damage to hair follicles, while laser intensity less than 5mW can not achieve the effect of activating hair follicles. This 5mW was first put forward by HairPro Laser Hair Growth Instrument on Peninsula, and it was also the first hair growth enterprise to apply for medical device registration certificate with this energy, and the first hair growth enterprise to obtain the second-class medical device registration certificate. Not only is the technology high, but their products are also very intelligent and intimate. It can grow hair directly when put on, and it can be taken off after 30 minutes. It is a complete fool's operation, which greatly satisfies many lazy cancer patients.
