For beauty salons, when choosing laser hair removal equipment, how to judge the authenticity of the machine? This depends not only on the brand, but also on the operating results of the instrument to determine whether it is really useful? It can be judged from the following aspects.
1. Wavelength
The wavelength band of hair removal machines used in beauty salons is mostly between 694 and 1200m, which can be well absorbed by the melanin in the pores and hair shafts, while ensuring that it penetrates deep into the pores. At present, semiconductor lasers (wavelength 800-810nm), long pulse lasers (wavelength 1064nm) and various strong pulsed lights (wavelength between 570~1200mm) are widely used in beauty salons. The wavelength of the long pulse laser is 1064nm. The melanin in the epidermis competes to absorb less laser energy and therefore has less negative reactions. It is more suitable for people with dark skin.
2. Pulse width
The ideal pulse width range for laser hair removal is 10~100ms or even longer. The long pulse width can slowly heat and destroy the pores and the protruding parts containing the pores. At the same time, it can avoid damage to the epidermis due to the sudden rise in temperature after absorbing light energy. For For people with dark skin, the pulse width can even be as long as hundreds of milliseconds. There is no significant difference in the laser hair removal effects of various pulse widths, but the laser with a 20ms pulse width has less negative reactions.
3. Energy density
On the premise that customers can accept it and there are no obvious negative reactions, increasing energy density can improve operating results. The suitable operating point for laser hair removal is when the customer will feel the pain of being stung, mild erythema will appear on the local skin soon after the operation, and small papules or wheals will appear at the pore openings. If there is no pain or local skin reaction during operation, it often indicates that the energy density is too low.
4. Refrigeration device
Laser hair removal equipment with a refrigeration device can protect the epidermis very well, allowing the hair removal equipment to operate with higher energy density.
5. Number of operations
Hair removal operations require multiple times to achieve the desired effect, and the number of hair removal operations is positively correlated with the hair removal effect.
6. Operation interval
At present, most customers believe that the operation interval should be adjusted according to the hair growth cycle of different parts. If the hair in the hair removal area has a short resting period, the operation interval can be shortened, otherwise the operation interval needs to be lengthened.
7. Customer’s skin type, hair condition and location
The lighter the client’s skin color and the darker and thicker the hair, the better the hair removal effect. The long-pulse 1064nm laser can reduce the occurrence of adverse reactions by reducing the absorption of melanin in the epidermis. It is suitable for dark-skinned customers. For light-colored or white hair, photoelectric combination technology is often used for hair removal.
The effect of laser hair removal is also different in different parts of the body. It is generally believed that the effect of hair removal on the armpits, hairline and limbs is better. Among them, the effect of hair removal on the tuck is good, while the effect on the upper lip, chest and abdomen is poor. It is especially difficult for women to have hair on the upper lip. , because the pores here are small and contain less pigment.
Therefore, it is better to choose an epilator equipped with light spots of various sizes, or an epilator equipped with replaceable light spots. For example, our diode laser hair removal machines can all choose a 6mm small treatment head, which is very effective for hair removal on lips, fingers, auricles and other parts.
