Currently, you can find different types of laser for hair removal. Laser hair removal is the most effective method of hair removal and, due to its results and the fact that it is virtually painless, it has become one of the most popular forms of hair removal. Many beauty centers offer laser hair removal services, for example, 3D Lipo London Laser hair removal .
Laser hair removal is based on the application of light. The transmission of light can be performed by two types of devices: a laser or another device that emits a pulse of previously filtered light. In addition, a conductive gel is applied to the skin that penetrates the hair follicle. The laser passes over the skin and its heat is absorbed by the introduced liquid. In this way, the follicle is burned. Throughout this post, we will explain five popular types of laser hair removal.
Ruby laser
Ruby laser hair removal is the oldest type of laser hair removal. It emits 694 Nm and the light is red. In addition, a cooling gel is applied to the area where the depilation will take place. Currently, it is rarely used and is only suitable for light skin with dark hair.
Soprano laser
The Soprano laser performs very fast low-energy shots, achieving progressive heating of the subdermal layer of the skin to no more than 35ºC. The laser accumulates most of the target’s temperature, up to 45-50ºC, reaching the ideal temperature to remove the follicle without overheating the epidermis. This technique supports dark skin and thick hair, including tanned skin. However, it is not as effective for fair skin and fine or blonde hair.
Alexandrite laser
This laser emits 755 Nm and is effective for removing thick hair, both dark and light. However, it is not best suited for dark skin, which has been exposed to the sun recently, or for facial hair removal. In fact, it is recommended that a specialist assess whether this type of laser can be used, taking into account the color of the skin and hair. Usually, several skin phototypes can be treated. In addition, gas, gel, or cold air is used to cool the skin and may require shaving.
Diode laser
Diode laser hair removal appears as an alternative to Alexandrite. Its wavelength is longer, allowing it to penetrate deeper into the skin, managing to treat thick and deep hair. In addition, due to its operation, it allows refreshing the skin more, making it possible to treat darker skin, even tanned. Diode laser hair removal works through the Selective Photothermolysis system. It consists of laser light acting directly on the hair follicle, penetrating the dermis. This gradually reduces the appearance of hair, as with each session the follicle weakens until it stops producing hair. Normally, dirty elimination is achieved through annual maintenance sessions. Among the main advantages of diode laser hair removal are:
Treatment for anyone, and can be performed at any age.
Long-lasting and effective hair removal.
Reduction of folliculitis.
Facilitates hygiene.
Nd Yag laser
This laser emits 1064 Nm and is ideal for all skin types, including tanned ones. However, its effectiveness is lower. In fact, for better results, more power is needed, making it the most uncomfortable system when compared to other laser hair removal treatments. It is only recommended for very thick and deep hair, not being versatile for other skin types.
