The principle of Diode laser hair removal

1. What is the principle of Diode laser hair removal?

The wavelength of the Diode laser hair removal system is 808nm, which can penetrate the epidermis to the hair follicle. According to the principle of selective photothermal, the energy of the laser is preferentially absorbed by the melanin in the hair, effectively destroying the hair follicle and hair shaft, and then making the hair lose its regeneration ability. ;

Since the photothermal effect is confined to the hair follicle, the thermal energy can be prevented from causing damage to the surrounding tissue and no scarring will be formed. At the same time, during the treatment process, the system has sapphire contact cooling technology, which can effectively cool and protect the skin to achieve painless, fast and permanent hair removal.

2. Why do you need multiple hair removal treatments?

The growth process of hair follicles is divided into growth phase, telogen phase and catagen phase. Only the hair in the growth period can be destroyed by the laser because it contains more melanin. Therefore, laser hair removal treatment cannot be successful once, and repeated treatment is necessary.

Generally, 4 to 6 times can achieve permanent hair removal. The treatment interval is 3-6 weeks (not more than 2 months). The best time for re-treatment is when the hair grows 2 to 3 mm,

3.Where are the hair follicles located on the skin? 

Hair follicles are mainly in the dermis

4.Why does damage to the hair follicles make the hair loss its ability to regenerate?

Simply put, the hair follicle provides the necessary environment for hair growth. If the hair follicle is destroyed, the hair will not reappear!
