From removing tattoos to eliminate wrinkles: use of the laser past hair removal

When someone says that the laser will be done, it is automatically thought that a session of elimination of body hair is subjected. And it is true, the laser (acronym for amplified radiation stimulated emission light) is a technique that is used to dismantle undo hair, but “this therapeutic technique has many other lesser known applications, such as eliminating stains, wrinkles, tattoos or scars, in the craft, in -meshitehuel, in -site, in -site, in -site, in -site -site, in -the -of -the -Site of Trueloologist, in -the -of -the -Site of Trueloologist, in the culptoologo -site of troueloologist, in -the -of -the -Site -of -the -Siteholeologist homeologists, in the culptoologist, in the culptoologoologoologist.

Laser is of course a very generic word that combines tools of a very diverse nature. So the person used to rejuvenate the face and remove a tattoo is not the same. For example, the use of one or the other depends on the wavelength, that is, the ‘color’ of its light and the depth to which it penetrates the skin, which is expressed in nanometer (Nm). For example, in the elimination of tattoos, lasers are used between 500 Nm and 1,000 Nm and in the facial rejuvenation up to 10,600 Nm.

Moreover, the lasers work on goals (called chromophors), they are those who absorb their energy. In the case of the human body they are hemoglobin, melanin and water. We assess the different use of this technology.

The vascular lasers work through the skin and transform into heat when absorbed by the hemoglobin of the wounded blood vessels. That is why “varicose veins, vascular spiders or angiomas are candidates treated with vascular lasers, such as the VBEAM or the Yag Neodymium,” says Truchuelo. “The pathologies that study with redness, such as rosacea or inflammatory acne, because they are lasers with affinity for the red color,” he adds.

The skin stains, such as those from the exposure of age or sun, as well as tattoos, are eliminated with a different type of laser, that of Picosegundos, which has “affinity for dark colors, such as brown and blacks,” Truchuelo explains.

What this laser does is cross the skin to a deep level and spray the tattoo pigment or spots in small particles that are later eliminated by the body (by sweat, urine …).

There are other lasers whose Chromofoor (Diana) is the water in the skin. Such as the CO2 laser, which broadcasts an infrared light that is absorbed by cell water. This is immediately heated and evaporated, eliminating acne scars, wrinkles, warts, sunscreen or keratosis. “That is why they are also called lasers of facial rejuvenation because they cause a voltage effect on the skin,” says the dermatologist.

The biggest advantage is its effectiveness, because after a single session there is a significant improvement in the surface and skin laxity. The main disadvantage is the time needed for recovery, although it is lower than that of surgical treatment.

Another option is intensely pressed light that is not a conventional laser, but is included in these techniques because it works in the same way. “Perhaps it is less effective than laser, but can achieve global skin improvement, unite the tone, improve collagen stimulation and have anti -Rosacea acne effects,” adds Truchuelo.

The pressed light is also used for hair removal, although the most common lasers for this purpose are Alejandrita, Diode and Neodimio Yag. “Everyone eliminates her, but not everyone serves any kind of hair or skin,” says Susana Corrales, a dermoetsthetic nurse.

The Alexandrite laser is more effective for dark and thin hair and light or small dark skins; Diode is indicated for dark skin and hair thicker and thicker, although it can also be used in clear skin that have thick hair; Neodimio Yag is for very thick and deep hair; And the pressed light serves many types of hair, but its action is more limited. “Cano -hair is contraindicated to being removed with laser because it does not detect it,” Corrales adds.

Because the laser is a very powerful energy source that can cause inflammation, irritation, sensation of pain, burns or infections, it is important to have certain precautions when using them. Among them, “employment, during their application, of highly approved protection glasses and not sunbathing the last month and the month after the session,” the specialists warn.

Moreover, the contraindicated during pregnancy and breastfeeding, some cases of diabetes, epilepsy, immunosity disorders, light sensitivity, if photo sensitizing medicines are taken or if you have active herpes or malignant lesions in the skin.
