Say goodbye to

The temperature is gradually warming up, and the problem of hair removal last year has been dug out again. Are the girls eager to show their legs?
As a "hairy monster" who has experienced countless painful hair removal experiences, I feel that it is necessary to talk about my "opinions" on hair removal.
Compared to the residual dark spots left by the razor, the damage to the body caused by long-term use of depilatory cream, and beeswax, I think is a very good choice.

This article focuses on laser hair removal, other hair removal methods will be discussed in detail later.



What is the principle of laser hair removal?
The key to the principle of laser hair removal is to use light of a fixed wavelength to pass through the skin surface to reach the hair follicles. The light energy is absorbed and converted into heat energy, which damages the hair follicle tissue, thus making the hair lose its ability to regenerate.
In layman's terms, the use of melanocytes in the hair follicles to absorb light of specific wavelengths selectively destroys the hair follicles without damaging the skin. Moreover, because black hair absorbs energy, hair follicles with higher melanin content The better the hair removal effect, the radon hair with insufficient melanin (shallow and short hair) is not so good.

Why does laser hair removal take several times to be effective?
The growth state of hair is in growth phase, telogen phase, and degenerative phase respectively, but one laser hair removal is only effective for hair follicles in growth phase (high melanin content ). The reason why the melanin content of the hair follicles in the catagen and telogen phases is less is that after these hairs are transferred to the growth phase (about 2-4 months), the laser can work according to each person's hair growth cycle, and the laser is usually in 4-4 months. 6 times will have an effect.

Who is not suitable for laser hair removal?
Dark skin, tattoos or scars cannot be epilated. Otherwise, the skin will be damaged. Improper handling can lead to blisters and scarring. Why refer to the basic principles of laser hair removal. At the same time, pregnant women are not suitable for laser hair removal. Pain can stimulate contractions and risk miscarriage.


Can home laser hair removal be permanently removed?
The energy of home hair removal devices is too small to achieve permanent hair removal. It just slows down hair growth.


How toPicking the right hair removal device for you?
Laser type: Pulse light IPL or laser
Light Wavelength:
1. The fixed single wavelength of the laser hair removal instrument is 810 nanometers, so those who choose the laser hair removal instrument don't need to look at it.
2. Pulsed light outputs composite light with various light wavelengths. However, short-wavelength pulsed light is risky for the safety of the eyes. The light wavelength of 470-540nm is transmitted to the back of the eyeball and absorbed by the macular melanin in the fundus, which will increase the temperature in the macula and cause permanent eye damage. .
Energy density: Within the suitable range of light wavelength, the higher the specific energy, the higher the hair removal effect, but relative will also be more painful.
Light output area: The light output area mainly determines the portability, the larger the area, the wider the range of each delivery.
Number of swipes: The number of swipes is also the service life of the hair removal device, which is also related to the energy level. Generally, the higher the energy, the lower the number of sockets.
Scope of application: If you have a baby who has lost lip hair or bikini hair, please pay special attention to the scope of application of the instrument.

Extra Features: If you have the budget, check out extra features like goggles and ice cooling.


Notes:

Be sure to shave your body hair before epilation. The pigment absorbs the energy of light. If the hair is not cleaned, the hair outside the skin will absorb a lot of energy. You can smell some of the hair being burned, and the skin will also cause a burning sensation, and the pain will be more obvious. Similarly, laser hair removal is not allowed on parts with tattoos or scars, otherwise it will damage the skin. Laser hair removal does not need to be exposed to the sun before. If you have some skin problems such as urticaria, skin allergies, or skin wounds, it is recommended to wait until the skin is stable and healthy. Sun protection is a must after shaving! !
