Factors affecting the effect of laser hair removal
The quality of laser hair removal is related to the thickness of the hair and the required laser pulse time and hair removal effect. The thicker the hair, the longer the laser action time. Compared with traditional laser hair removal, laser hair removal eliminates skin pigmentation and skin In case of inflammation, the contact cooling laser head, the sapphire window will be close to the skin during the treatment, so that the local epidermal temperature can be cooled to 5 degrees, which protects the normal skin and improves the curative effect.
Laser hair removal is best for people with light skin tones and dark hair, and is intended to remove “dark pigment”. What I need to remind everyone here is that after laser hair removal, some hairs may regenerate, but relatively speaking, they will be thinner and softer, which is not easy to be noticed or discovered.
Everyone’s physique is different, and the hair thickness and growth ability are also different, and the effect of hair removal is also different. Therefore, different individuals adopt the same hair removal method. Some sensitive people may be able to remove all hair at one time while other people who are not sensitive may have to take it off many times to achieve some effect.
The skin color and hair color are different, and there will be some differences in the treatment. Because the selectivity of laser treatment is very strong, it is determined according to the pigment in the skin. The hair removal reaction is different. On the same individual, the hair removal effect of different parts is also different, because the pigment of different parts is also different.
In terms of equipment, different treatment equipment has certain differences in effect. The light source of the laser has a great influence on the effect of laser hair removal. That is to say, the treatment effect of some instruments with relatively large laser light source intensity will be lower Better than those with less powerful light sources.
In fact, when the light beam is irradiated on the skin, consumers may feel a slight pinprick, and then may feel a slight burning of the skin. The degree of discomfort or pain will vary with different types of equipment, thickness and thickness of hair, and body parts. Generally speaking, the greater the energy released by operating the device and the thicker and thicker the hair, the greater the pain that may be caused.
Appropriate freezing procedures can reduce discomfort of the laser hair removal process, but even with the same type of laser, different brands may use different freezing methods, such as applying freezing gel to the skin before hair removal; some optical instruments will be equipped with freezing contact surfaces (cooled tip), which is used to press on the skin before irradiation to reduce the temperature of the skin surface through conduction; some devices are also equipped with a device for spraying cryogenic sprays, which will spray out the gas before releasing the beam each time. After volatilization, it will achieve the cooling effect. Depending on the coping method, the degree of discomfort caused will also vary.
