What You Need to Know About Diode Hair Removal

1.What is the principle of permanent hair removal?

The principle of modern hair removal technology is to kill the hair follicle cells under the skin through heat, so as to achieve permanent hair removal effect. The skin is composed of the epidermis, dermis and subcutaneous tissue, and the hair follicles are located in the subcutaneous tissue area under the dermis, which means that efficient and comfortable hair removal requires high requirements on the wavelength of the laser and the cooling system.

At present, the most popular hair removal technology on the market is diode hair removal, which stands out among all technologies with its excellent heat dissipation system, good wavelength control and mature cost control.

2.What is diode laser hair removal?

A laser is a monochromatic focused beam, which means it has only one wavelength and color. Different wavelengths of light have different penetration capabilities to the skin. The 808nm diode laser can perfectly act on the hair follicles, so it will not damage other skin tissues during treatment.

Semiconductor laser, the wavelength can be selected from 755nm/808nm/1064nm, for light-colored, yellow and black skin, it has ideal tissue penetration and selective absorption. The treatment spot is large, and the front end of the laser handpiece is equipped with a contact cooling system. The treatment is safe, fast and convenient. It is currently the most clinically used laser hair removal device.

3.What is IPL Hair Removal?

IPL is intense pulsed light, it's not a laser, it uses a xenon flash lamp, which emits diffuse light. That means it's made up of many different wavelengths, or colors, and can't be focused like a laser. IPL has a wavelength of 500 to 1200 nm. But it also uses light energy to slow and reduce body and facial hair growth.

Part of its energy will be absorbed by the skin, and the thermal sensation of the skin will be stronger, so the efficiency of hair removal will be lower. But because of this, it can be used to treat many skin diseases, for example, it can be used to remove freckles, remove red blood, and tighten the skin.

4.Which is better for hair removal treatment?

Both laser hair removal and IPL work by converting light energy into heat to heat the hair follicles, thereby reducing hair growth. The biggest difference is that the diode laser is a highly concentrated beam with very concentrated energy, which can "explode" the hair follicles at a fixed point, so there will be no "hit and miss" situation. This precise wavelength makes it a more efficient treatment than IPL, so fewer sessions are needed and the treatment experience is more comfortable in the long run.

5.How is hair removal done?

a. Remove makeup, clean the treated area, and shave hair

b. Apply cooling gel, set treatment parameters according to skin type, treatment area and hair condition

c. The handle is perpendicular to the skin, press down on the skin slightly with a certain force, slide at a constant speed, and add gel continuously during the treatment

d. Treatment time varies by body part, approximately 15 to 30 minutes. Due to the hair growth cycle, the whole laser hair removal process is 3-5 times.

6.Precautions after hair removal

a. Avoid sun exposure for 1 week after treatment, always use SFP 50+ sunscreen if the treated area is exposed to UV rays.

b. Avoid going to places with high temperature, such as steam room, sauna, jacuzzi, swimming pool, and use warm water with lower temperature when taking a bath.

c. Do not perform other laser treatments within 2 weeks before and after treatment.

d. If you experience any side effects such as hyperpigmentation and reddened skin, call your doctor for treatment instructions.

e. Laser hair removal cannot be completed 100% at one time, in order to achieve the best effect of diode laser hair removal, please complete the complete treatment
