Faced with an onslaught of Laser:

* the skin is heated less and takes longer to cool;

* the bulb absorbs more laser radiation, heated, and it takes longer to cool.

This effect can be quantified through the concept of TRT (Thermal Relaxation Time, or thermal relaxation time), at which time the tissue in question has removed half of the heat energy produced by the laser impact. This time is for the epidermis in general, 8 to 10 milliseconds, and the pilo sebaceous follicle, from 20 to 60 milliseconds.

If we apply an impact of sufficient energy, with a single shot can destroy the bulb, but also heats the epidermis, the amount of melanin present.

The purpose of hair removal is to have a laser unit powerful enough, with an impact, getting the destruction of the follicle, affecting skin to a minimum.

But if only one impact of laser hair removal can be achieved, we can use a number of impacts applied to a range well studied. With the first impact, the skin is warmed slightly and dissipates heat quickly, the bulb is heated more and takes longer to dissipate heat.

If we apply another impact at a time when the skin is almost all the heat dissipated (due to its greater rate of heat loss) and the bulb has only its temperature fell only slightly, we will make the bulb further enhance its skin temperature while increased only minimally.

Thus, by acting successively shot to shot (three, four, five) with the appropriate interval, we get the bulb reaches the desired temperature for destruction with minimal involvement of the skin.
Laser hair removal practice

The hair has different thicknesses depending on the area, and then we vary the energy necessary for destruction. In addition, hair has a wide range of color.

Ideally, laser hair removal would be pitch black outside, but we found gray hair, brown, blond, etc.. And matter the color of the skin, as expressed by the different skin types.

For laser hair removal is also very important to the depth of the follicle, which varies according to anatomical sites and personal characteristics.

This is of interest because the laser effectively only reaches a certain depth, depending on their nature and power.

Finally, it is important to take into account the stage of growth that is hair. The laser acts positively in the anagen phase, whereas the bulbs located in telogen or catagen phase will be very little affected by laser radiation.

The hair is composed of: root, stem, bulb, sebaceous glands, pilo erector muscle, dermal papilla and the bulge that contains the cells on which we act. We can divide the life of the hair in three stages:

1. Anagen phase: the growth phase
2. Catagen phase: the phase distribution of follicle
3. Telogen phase: it is the resting phase

For laser hair removal define what our goal. If we want a permanent hair removal or long-term, we must act on the hair follicle destroying the bulb, or more specifically, cells that give rise to hair.

To do this we will build on the fact that this whole area has a lot of melanin, while the skin has less melanin. Therefore, the laser is absorbed very selectively by melanin, and in very few of the other components of the skin.

The laser must penetrate enough to act effectively. Not all lasers used in hair removal have the same penetration, depends, as we have said, the nature of the radiation they produce. The important thing for us is that when the laser hits the target (melanin) its energy is absorbed and converted into heat.

As in any local application of heat to the body, immediately there is this heat dissipation by different organizational structures, and therefore, a cooling until it reaches body temperature.

The purpose of the Laser hair removal is achieved in the target area the temperature needed to destroy cells pilo sebaceous follicle matrix. This temperature is around 70 ~ 80 degrees.

The problem is getting time this temperature by the laser.
Effects of heat in the body point

If a specific part of body heat is applied, the effects vary with the temperature achieved.

*to 45 º vasodilation occurs

*to 50 ° enzyme affects cell metabolism, although the cells are kept;

*around 60 º is disruption of cell membrane proteins are denatured and the cell dies.

*to 70 degrees is a total distortion of collagen and

*to 80 ° is coagulation necrosis

*if they reach 100 degrees, as in the electric scalpel, not only is necrosis, but cell vaporization.

Therefore, to get the hair need to reach a temperature of about 70 ~ 80 º to the bulb pilo sebaceous. To do this we must remember an important concept as set out above, that of dissipating heat.

Complaints to the beauty centers for skin lesions is often accompanied by financial claims, which can reach several thousand euros, to pay for the center caused the injury. The amount depends on the degree and extent of burns.

In many centers, where medical personnel and lack of adequate training to prevent injuries and treat them if they occur, can not cope with the complications in treatment. In the absence of solutions, patients should see their regular doctor to find a remedy.

Burns can cause intense pain in the affected area. A dermatologist is the right person to recommend an appropriate treatment for the problem. In some cases, the center has caused the injuries offered to bear the costs of negligence, but in other cases not. Often it is in these times when the victims reported the establishment.

In spite of following the treatment by a dermatologist, it may happen that remain irreversible scarring. Sometimes the marks can be removed using skin lightening creams, but this does not work in all cases. The consequences of a bad hair removal can be definitive, because it is so important to have security guarantees as a first condition.

Doctors are warning that there is still no public awareness of the consequences of sun overexposure, and subjected to extensive skin tanning sessions regardless of health. Professionals indicate that a list of factors harmful to the good condition of the skin, such as the snuff, the sun, stress and pollution, the most damaging is the sun.

Despite the many prevention campaigns have been launched to inform the public, have considerably increased cases of skin cancer. Fortunately, this disease can be cured if diagnosed early, but the best option is to save attacks on our skin.

The only element that seems persuasive success is the aesthetics. Many people have realized that too much sun ages and damages the appearance of your skin, so take care more. Medical consultations are also about this aspect, apart from pathological risks.

The advice for this season are:

- Take into account skin phototype itself and its resilience to sunlight.
- Bask in the daylight hours when the shadow is projected on the floor is longer than your height.
- The sun stimulates vitamin D, but with 20 minutes of exposure to the week in 10 square inches of skin is sufficient.
- Conduct a simple hygiene, showers and baths without excessive.

As always, the market offers several options to choose from, you can now choose to have laser hair removal at home for a small fee by a pulsed light device that can be used by anyone, but for which there is no evidence of its effectiveness or its security. The reality is that to use a device of this kind, one must know in full operation, it is best to be well trained and be an industry professional, training is required.

Keep in mind the skin type that exists in different areas to treat, may be more or less sensitive, with different pigmentation and even need more or fewer sessions, there may be risks of burns if the device is controlled entirely and its intensity. We must consider the type of hair and its parallel and see if it can be subjected to a treatment or not, this must be someone supervising qualified specialist in the field of laser hair removal.

It is therefore the creation of a new technology that dermatologists and other specialists renege on their dangerousness to be sold to all who request it without training or prior training by the free choice of hue and pigment use in respect skin and hair, and by its low efficiency in the results. For now, we recommend laser hair removal clinics under medical supervision, at least until proven 100% effective and especially the safety of home appliances.

However, hair varies across cultures. For example, some types of hair called the area, as in the case of English in Brazil.

In some geographical areas are not given important to have hair, like fur mustache in France, where it is not picking their armpits. Even in other areas, such as the Japanese have valued more pubic hair than the average.

Consequently throughout history have developed several methods and a variety of hair removal, although a good choice will depend primarily on the needs of individual women and the important factors such as characteristics of the skin, hair type and the area to treat.

It is then very useful to know the advantages and disadvantages of hair removal techniques so that we can get the best results depending on the specific needs of each moment. So we obtar with hair removal techniques such as permanent or temporary solution. In recent years we have been experiencing a boom in laser hair used is becoming more common both women and men.

Meanwhile, there are also blades that maintain the same time as shaving a thin lotion, the skin at the same time and thus preventing it comes to skin irritations. Often they used additional shaving foam, so that the blade glides over the skin better. But after only one or two days, to feel again stubble, so it is then shave again. Without water, but otherwise does the same dry shaving, but also in their holds: After two days must be reworked

I had already thought a laser therapy, however, these costs alone for such back € 250-300. That’s a lot of money, but you can buy a lot of hair removal cream or razor. So I went in search of other methods of hair removal on the body and came first to a device, which was to remove the hair with light flashes. Furthermore, I wanted to inquire further, and came on it, that we have in our company, even such a similar product for themselves soon, that Remington IPL5000 i-Light. Through this unit, I informed myself again on the Internet, the Remington-field and also with my colleagues in our company. Equipment was purchased.

Permanent hair removal is one of the great aesthetic solutions in recent decades. Increasingly affordable, with no side effects, provides final results to all those people who want to dismiss facial and body hair forever.

Are all? Until recently, laser perfect subjects were those with very light skin and dark hair. The reason is that the beam of light looks dark hair with melanin, in contrast to fair skin, blond hair when it fails to find, as if the skin is very dark, with which it is not capable.

However, technology increasingly closer to permanent hair removal darker skin types.If you are dark in nature, must resort to the IPL, or intense pulsed light. This is a mixed light whose behavior is similar to a light bulb: travels in all directions. IPL teams are less precise but more versatile, so they are ideal for darker skin.

Our recommendation is to go to a permanent hair removal center where you can examine a dermatologist to examine your case. There are alternative solutions for tanned skin and the application of a bleaching agent, but must be under the supervision of a physician. At home Increasingly popular platforms hair removal at home, stop allowing the hair in a painless and effective. Unlike the professional laser, the results are not definitive, but are a negligible solution: remove the hair for about 3 months, do not hurt and are considerably more affordable.

laser brown From Remington just launched i-Light, a unisex epilator IPL. Removes hair professionally for 12 weeks, ie 3 months without worrying about the hair. Works with a pulse of light whose energy is absorbed by the melanin in the hair follicle, disabling its growth temporarily.
It consists of a base and a lamp that shoots beams of light every two seconds, allowing undergo treatment throughout the entire body in just 50 minutes. A limited number of shots, but on reaching the 150 machine contact us and we can buy a spare lamp, which costs less than 30 euros.

Its technology is effective against hair but nothing aggressive to the skin, so that does not raise the temperature does not require the use of any gel refreshing after using this product. It does not work on stains, tattoos and moles, so that we can implement in areas that have these irregularities. The price of i-Light with 1,500 shots with 3 spare lamps, a DVD and a bag to store it is 299.90 euros.laser brown From March 1 Lume is available from Philips, a complete home .

Its technology is also intense pulsed light, soft skin and effective against hair, plus it is more effective in skin and hair types of the laser. It has a gauge to adjust the intensity according to skin type, but is not suitable for very very dark skin. Ideal, yes, in addition to a treatment of professional laser hair removal. The price of Lume, with 40,000 shots, is 499 euros.

2. Depilatory cream
When applied to hair, the chemicals in the cream causes hair above the skin surface to disintegrate. The good thing about such cream is the hair stubble do not appear as thick as when I shave. But I hated the smell of the cream.

3. Waxing
This basically is mass-pulling of all the hair that get stuck on a wax strip. I found the wax to be rather messy and waxing was painful because I have to pull fast and hard. The wax is difficult to wash off and I don’t like the smell. Also, I would need to let the hair grow out by at least 1cm otherwise there wouldn’t be enough length to allow the hair to stick on to the wax strip. The effects only last for a few days before hair starts to grow out again – not enough to justify the amount of work and pain.

4. Epilator
An epilator is a small device plucks out hair (like a multiple tweezers) at high speed. It was painful initially. As painful as waxing but without the bad smell and waxy messy. After a period of using the epilator, it got less painful – I think because the hair roots are weaker or I just got used to the pain.

Epilators can pluck out very short hair. Hair is plucked out together with the roots so regrowth is slow and there are no stubbles. I only need to use it once every 2 or 3 days. Even if I forget, it won’t look like a disaster.

The only drawback is the initial price you have to pay for them. Epilators are not cheap but I think it’s a good investment for personal grooming. I bought my epilator (brand: Epilady) for SG$80 more than 10 years ago and it’s still working fine. That means I paid only $8 a year for hair removal.

5. Laser hair removal
I still was not fully satisfied with having to use the epilator. Laser hair removal promised to remove all my underarm hair once and for all. The laser was supposed to “burn and kill” the hair from the roots. The dark hair would absorb the heat from the laser to burn the hair follicle which causes hair growth. I signed up for 5 sessions with a doctor (I can’t remember the exact price – must have been at least a few hundred dollars). A number of sessions would be needed because not all the hair would be present at any particular point in time (some may have just dropped off).
