Laser hair removal, at home?

The only appliance of depilation with pulsed light totally safe and effective for domestic use’. This is one of the many messages issued by different brands to announce this type of devices and allow laser hair removal can be done without leaving home. What do dermatologists think about it?

Faced with the increase of these equipment and the forecast of new competitors in the next month, it was inevitable to address this issue at the 37th National Congress of Dermatology and Venereology.After analyzing the existing studies, the experts agree to point out some shortcomings . “They are work done three months, more than four and a half months, and at least should analyze efficiency and safety for half a year,” says Esther Cuerda, a dermatologist at the Clinica Planas in Barcelona.

They usually show a hair reduction of 50%, they do not register complications and, finally, they conclude the efficacy and the safety for their domestic use. According to José Luis López Estebaranz, head of Dermatology at the Alcorcón Hospital in Madrid, “these works are sponsored and must be read in quotation marks”.

Despite the criticisms expressed by the lack of more complete studies, “these devices work for temporary depilation,” says Dr. Cord. In addition, pulsed light devices for the treatment of some skin diseases (such as vitiligo) may be useful . “They achieve greater compliance, reduce cost and avoid travel.”

For the dermatologist at the laser hair removal in phoenix, the conclusion is clear: “Although each product should be evaluated separately, long-term studies are lacking, these devices can only be used with some skin types, they should not be applied to the face or neck , The sessions are more frequent than we would like and there is a risk: that the hair becomes thinner and it is more difficult to eliminate it.

The ideal to counteract this kind of risk, the experts who have participated in these days, would be to pay more attention to this sector . “There is a legal vacuum regarding this type of cosmetic products without prescription. Given that there is some risk, it would be interesting to regulate it so that the person who uses it is in some way properly informed and trained. It is very important that they know how to handle these devices. ”

Is mesotherapy useful?

Other topics have been discussed during this congress. Thus, for example, many dermatologists defend mesotherapy (intradermal injection of hyaluronic acid and vitamins) as a technique that promotes collagen and helps to “improve tone, elasticity, reduces roughness and sagging, and gives greater luminosity to the skin “Says Natalia Segui, dermatologist at the Dermatologic Valles Clinic (Barcelona).

The problem is that “there are only observational studies and very few. There are no controlled clinical trials in facial mesotherapy and the absence of evidence does not confirm the effectiveness”, criticizes Elia Roó, coordinator of the Unit of Aesthetic Dermatology Sur Hospital (Madrid), Who takes the opportunity to denounce what he shares with many of his colleagues. “All these products approved by the US drug agency (FDA) require clinical trials before, while in Europe they are not necessary to approve them.”

Regardless of this observation, the experience of dermatologists shows that the side effects are few and mild, for example, pain or edema following injection.

On the other hand, dermatologists have not forgotten to discuss one more question: Is it legal to dispense cosmetics in private clinics? There is no doubt. “It is legal whenever it is carried out as a business other than for tax purposes,” says Agustín Alomar, Hospital San Pau de Barcelona.

A Apparently, more and more specialists opt for this route in their private consultations and the results are positive. Manuel Asín Llorca, of the Aesthetic Dermatological Center of Alicante, confirms: “We offer a more patient service, we improve the price, we avoid displacements to acquire the indicated products, start to use them first and it is profitable.” Whether it is ethical or not depends on the personal opinion of each specialist.
