Is laser permanent hair removal effective?

Many of our friends have thick body hair. In the summer, they will obviously find that the hair on their legs and all over the body is thicker. Therefore, they always want to effectively remove it through various methods. However, many hair removal methods are severely painful and difficult to maintain for a long time. Laser hair removal is a method that can permanently remove local hair. The following editor will introduce the effect of laser permanent hair removal.

Laser hair removal is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength energy pulse width, the laser can penetrate the skin surface to reach the hair follicles at the root of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thereby making the hair lose its ability to regenerate. At the same time, it may damage surrounding tissues and cause mild tingling. Laser hair removal is a safe, fast and long-lasting hair removal technology.

Clinical trial results of laser hair removal: After 3 to 5 treatments, more than 95% of the cases had 80% of the hair fall off, and the hair became less, thinner, lighter in color, and grew slower. If only 1-2 treatments are performed over time, all cases have demonstrated a 30% to 50% hair reduction. In most clinical cases, an average energy density of only 10~20J/cm2 is sufficient for efficient hair removal, thus avoiding possible medical risks such as burns.

Influencing factors

1. Different laser hair removal devices have different effects

In terms of equipment, different treatment devices have certain differences in effects. The laser light source has a great influence on the effect of laser hair removal. That is to say, some instruments with relatively high laser light source intensity will have better treatment effects than those with low light source intensity.

2. Physical differences also affect the effect of laser hair removal

Everyone's physique is different, and the density and growth ability of hair are different, so 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 the hair in one go, while other insensitive people may have to remove the hair many times to achieve some effect.

3. Differences in skin and hair color lead to different laser hair removal effects

The treatment will be different for different skin and hair colors.

The selectivity is very strong, it is determined according to the pigmentation of the skin, that is to say, the hair follicles in different parts of the body react differently to laser hair removal. In the same individual, the hair removal effects in different parts of the body are also different, because the pigmentation in different parts of the body is also different.

When removing hair, it is best to choose a more appropriate hair removal method according to different parts of the body. Local hair removal can be done through laser methods. After using laser hair removal, it is best to pay attention to effective care, try to reduce various inflammations caused by hair follicle infection, and also pay attention to sun protection.
