Hello, the principle of photon hair removal is to irradiate the normal epidermis through selective photodegradation of patented intense pulsed light source, penetrate the skin and reach the root of hair follicle. Melanin in the hair shaft and hair follicle is absorbed and converted into heat energy, thus raising the temperature of hair follicle. Lido Plastic Surgery introduced that when the temperature rises to a high enough level, the hair follicle structure is irreversibly damaged. Through a natural physiological process, the damaged hair and hair follicle are removed, while other surrounding tissues are not damaged, thus achieving painless hair removal.

The advantages of photon hair removal are: 1. The pain is relatively small. 2. Hair removal is thorough. 3. It won't hurt the epidermis. 4. It's very fast. 5. The pigmentation after depilation is very close to our skin.

However, there are some cases where photon hair removal is not applicable: 1. Local or systemic inflammation, photosensitivity, people who are using aspirin or antioxidants, and people who are mentally unhealthy. 2. It is recommended not to accept photon hair removal treatment in the following situations: black birthmark, diabetes, psoriasis, eczema or dermatitis, skin cancer.

The main hazards are: 1. Laser can only treat one kind of skin, but has limited effect on another kind of skin, and all hair removal lasers belong to Class IV lasers, which are very dangerous to human eyes and soft tissues. 2. There will be slight redness and edema at the treatment site.
