Body hair is a real nuisance for men and women, and therefore removal techniques are increasingly high. Before choosing the best treatment for your case, you need to understand the differences between each technology.
In addition to the traditional depilation with hot wax and blade, other more technological methods have gained space, such as laser depilation and intense pulsed light.
Laser hair removal acts on the destruction of the hair follicle, in a punctual way (monochromatic), making the application a little more painful. It has better results on white skin, with dark and thick hair, but its structure does not eliminate blond and white hair.
The performance of intense pulsed light is based on the delivery of energy to the melanin present in the hair shaft, which, by selectively absorbing the light, heats up and has its germinal structures destroyed. For this reason, you’ll feel less pain and its scope is greater, and is also indicated for people who have thin, blond and red hair.
But have you ever heard of any depilation device that is capable of removing white hair? If your answer is yes, today you will understand why this proposal is one of the biggest myths in aesthetics.
Depilation has been with humanity for a long time, the first record of this activity was in Ancient Egypt, at that time the hair was removed with a mixture of honey, clay and sandalwood.
Since then, depilation techniques have been evolving and being improved until reaching definitive depilation, the great craze in the beauty market today.
However, when we talk about permanent hair removal, why is no device effective in removing white hair?
Read to the end and find out why.
Permanent depilation is performed using light, which is why the technologies on the market are Intense Pulsed Light (IPL), Laser and LED. For this reason, in some materials, you will find the denomination: photoepilation, that is, photo (light) + depilation.
Light is a source of energy and it is this energy that is triggered by the depilation device, but how does it reach the hair root?
There are some structures in the human body that have “color”, such as red blood cells and melanin, they are called chromophores.
Melanin is responsible for the pigment of the skin and hair, in addition to being responsible for carrying the energy from the depilation device to the hair bulb so that it can affect and damage the nutrition of this structure.
That is why it is very common for professionals to say that the result in patients with low phototype (light skin) and dark hair is much better, as the energy is concentrated on the hair and not on the skin.
It is also for this reason that people with higher prototypes are more sensitive to permanent hair removal, as the energy acts both on the skin and on the hair and without melanin, the energy cannot get to where it needs to go to damage this nourishing structure.
With the pulsed light treatment, the light beam is fired in a more widespread way and reaches the hair more superficially. Not being able to eliminate them for good, but weakening them.
Laser hair removal works with the firing of a laser light beam capable of attacking the hair and by reaching its root, it manages to “kill” the structures responsible for growth.
The wavelength can vary according to each type of laser, which will directly impact the efficiency, comfort and safety of each one.
Also during application, the energy emitted by the device is attracted by the pigmentation (melanin) of the hair follicle, which leads to the weakening and destruction of its root.
The Intense Pulsed Light device is very versatile and can be applied in the most diverse protocols, according to individual needs. It is indicated for the face and body regions, such as armpits, groin, legs, chest and hands, with different purposes.
According to each person's characteristics, the light will act directly on the skin's pigments, improving texture and appearance, promoting a rejuvenated appearance. It is a treatment that does not interfere with routine, indicated for the four seasons of the year. Its results appear gradually, over the sessions, without causing any damage.
Treatment of Blemishes and Melasma
The best known use of Pulsed Light is in the treatment of skin signs like sunspots, melasma, freckles and rosacea, as its flashes work directly on skin pigmentation. This is a technology that promotes skin whitening, improving blood oxygenation at the treatment site.
Its flashes identify the melanin pigments, heating the place where they were applied. In this way, tissue coagulation occurs and stimulates the production of collagen and elastin fibers, which minimize dark spots on the skin by lightening unwanted signs.
Dilated pores and acne scars can also be treated with Pulsed Light, as it promotes cell renewal. Another point is the contraction of blood vessels below the epidermis, which attenuate open pores and reduce skin oiliness.
Pulsed Light for Signs of Aging
In addition to improving blemishes, Pulsed Light acts on other signs of aging. It promotes facial support, minimizing fine wrinkles and preventing their appearance, as well as mitigating the presence of facial vessels, expression marks and photoaging.
The light shots, when reaching the tissues, heat the region, stimulate coagulation and activate chemical reactions in the body. With this, the skin increases collagen production, renewing the area.
What you need to know is that white hair is different, it lacks melanin.
Without melanin what happens? The energy from the hair removal device cannot be transported to the hair bulb so that the nutrition structure is affected.
Therefore, no depilation device on the aesthetics market is capable of eliminating white hair.
