Why choose diode laser hair removal? 2 Things you must know

As a classic hair removal method, the shaving knife occupies half of the market, but whether it is shaving knife or depilatory cream, it can only remove the exposed hair.

In a few days, the hair will grow back quietly, become thicker, harder, and prickly. The traditional hair removal methods can never get rid of the deep nest of hair .

Therefore, frequent hair removal is required, even two or three times a week. But frequent shaving can increase the risk of ingrown hairs, causing them to grow crookedly or curl inwards, get stuck into the skin, and even cause folliculitis in severe cases. Therefore, if you want to remove hair more safely and permanently, you still have to rely on energy that can reach the hair follicles, such as light.

The results of the survey found that when choosing a hair removal method, more than 80% of hair removers pay attention to safety, durability or hair removal effect. And laser hair removal can meet these three points at the same time.

At present, the most recommended is medical beauty laser hair removal. Compared with the short-term effect of the razor, the unbearable pain of beeswax hair removal, and the strong irritation of hair removal cream, laser hair removal have both efficiency and effect.

In fact, this is also related to its working principle. After reading the following, you will know why it is the hair removal method with the best experience, the best effect, and the longest duration among all current hair removal methods.

1.Working principle

Laser hair removal is actually based on the principle of selective photothermal dynamics. After reasonable adjustment of laser wavelength, energy, and pulse width, the laser can pass through the surface of the skin to reach the root hair follicles of the hair.

Because the light energy can be absorbed and converted into heat energy that destroys the hair follicle tissue, the hair loses its ability to regenerate, and the surrounding tissue is not damaged, pain is not particularly obvious.

Because our hair follicles and hairs are rich in melanin, the darker the melanin is, the more laser heat it can absorb. At this time, the temperature will rise sharply, and the hair will be removed.

This is like basking in the sun in winter, people in black clothes are hotter than those in white clothes.

Meanwhile, melanin absorbs more heat, and the risk of heat damage and pain sensation to the skin will be higher, and the pain felt by the skin may be stronger;

On the contrary, with light skin, the energy received is less, and the pain is relatively lower. The pain of laser hair removal is different for everyone, but generally speaking, it is within the tolerable range.

So, in a nutshell, if the hair is darker and thicker, the effect of laser hair removal is better.

And if the hair color is lighter, or if it is white hair, the effect of the laser will be reduced, or even unable to work, because white hair does not contain melanin.

Laser hair removal is currently the only hair removal method that can almost permanently sever hair, because it can directly hit the old nest of hair follicles.

However, our hair has a growth cycle, which is generally divided into 3 phases. Different hair follicles will be in the growth phase, catagen phase, and rest phase respectively, and cycle repeatedly in these 3 phases.

So you will find that the hair can never be completely removed, even if it is plucked by the root, it will still grow back.

The advantage of laser hair removal over traditional hair removal is that laser hair removal works directly on hair follicles, and the more times laser hair removal is done, the more obvious the effect will be.

With the number of treatments, the hair will become finer and softer, the color will become lighter, and even to the point where it will no longer grow.

Therefore, in order to deal with the hair follicles in different periods, we generally need to do laser hair removal every 1 to 2 months, at least 4 to 6 times before we achieve a more ideal hair removal effect.

2.Advantages of laser hair removal

Now, some people may have doubts, will such frequent hair removal be harmful to the body? Will it affect sweat glands? In fact, this is a misunderstanding, and it is not the case.

First of all, laser hair removal will not harm the body.

Hair removal only affects the hair, and targets melanin, it will not affect the surrounding tissues, let alone the deep tissues.

It's just that before receiving laser hair removal, you may have to bear a certain risk of pain, which is different for everyone.

There is also a slight tingling sensation during the hair removal process, a mild burning sensation after the operation, and mild erythema and follicular papules may also appear on the skin, but these generally disappear within a few hours.

Secondly, many people worry about whether frequent hair removal will affect perspiration. In fact, hair follicles and sweat glands are two independent tissues that do not interfere with each other. Hair grows from hair follicles, while sweat glands are next to hair follicles. The two are not one thing.

Hair removal only acts on the hair in the hair follicles, and does not damage the sweat glands, nor does it affect the sweating of the sweat glands.

Therefore, even if the hair follicles are damaged, people will still perspire normally.
