Cosmetic facial skin care device in the form of a mask

The present invention relates to a cosmetic facial skin care device in the form of a mask by photomodulation and electrostimulation as well as a cosmetic process for the care of the facial skin by photomodulation and electrostimulation implemented by the device according to the invention, allowing, according to the program used, to increase the cellular turnover of the skin and / or the effectiveness of the cosmetic skin care and / or the radiance and homogeneity of the skin complexion and / or the endorphin secretion of the skin. the skin and / or the firmness of the skin, and / or makes it possible to prevent the appearance of wrinkles and / or the appearance of the spots and / or the appearance of the signs of fatigue of the skin and / or makes it possible to reduce the wrinkles and / or rosy skin tone and / or reduce the presence of stain and / or regulate the sebum level of the skin and / or reduce redness of the skin and / or skin imperfections and / or have a detoxified effect ant of the skin and / or an anti-pollution effect of the skin.

The field of the invention relates in particular to the care of the facial skin by photomodulation and electrostimulation.

The maintenance of a beautiful skin, especially of youthful appearance and without imperfections is nowadays a constant concern. Over time, and particularly chronological and / or photoinduced aging, the skin undergoes numerous modifications and degradations that are reflected, at the tissue level, by a disorganization of the architecture of the epidermis, of the dermal junction. epidermal, dermis, as well as blood irrigation and innervation systems, and a slowing or disruption of various cellular metabolisms, such as those involved in the balance of the barrier function or involved in melanogenesis. At the cellular level, aging thus results in an alteration of the physiology or metabolism of the main cell types such as dermal fibroblasts, epidermal keratinocytes, and also melanocytes.

Skin aging results from two separate and independent processes that involve intrinsic or extrinsic factors. Intrinsic or chrono-biological aging corresponds to age-related normal or physiological aging.

The intrinsic aging results in a slowing down of the renewal of the cells of the epidermis and the appearance of fine lines or wrinkles. At the level of the dermis, the biosynthesis of macromolecules such as collagen decreases with age, changing the mechanical properties of the dermis, hence slackening of the skin, one of the clinical signs of aging. Especially at the level of the face, this intrinsic aging is marked by the appearance of wrinkles like the nasolabial folds, located between the wings of the nose and the corners of the mouth, the wrinkles of the crow's feet at the outer corner of the eyes, the vertical wrinkles between the eyebrows said wrinkles of the lion, and the horizontal wrinkles of the forehead.

Extrinsic aging corresponds to aging caused in general by the environment and corresponds more particularly to the photo-aging due to exposure to the sun, and to smoking. Photo-induced skin aging, that is to say, caused following exposure to the sun is still called photo-aging or heliodermia. Photo-aging is the result, at the level of the dermis, of the degradation of the collagen fibers resulting in particular in clinical alterations such as thick wrinkles and the formation of a soft and tanned skin. The aging of the skin is accelerated by chronic UV exposure. Especially in the face, this extrinsic aging also results in the appearance of brown spots.

There are cosmetic treatments to reduce imperfections and the effects of aging resulting in an appearance of wrinkles on the face. Among these cosmetic treatments include, for example, anti-acne care to promote desquamation and / or limit microbial growth, anti-aging care in the form of creams containing active ingredients such as antioxidants , such as polyphenols, vitamin C, or flavonoids, enhancing the production of collagen and elastin, such as resveratrol, vitamin A, algae, or copper, assets promoting cell regeneration, such as essential oils of immortelle and lemon balm, or amino acids, moisturizing actives, such as hyaluronic acid. These creams, however, can cause significant irritation in the form of tingling, heating, redness or itching. There is also treatment to reduce the presence of tasks, taking the form of creams containing active agents such as lightening or depigmenting agents such as antityrosinase or depigmenting agents to reduce the production of melanin, taking mainly the form of Arbutin, L-niacid, kojic acid, glabridin, vitamin C, or rucionl, or antioxidants to repair sun damage such as vitamins C and E or polyphenols.

There are also a large number of cosmetic treatments for reducing imperfections and the effects of aging, for example "peels" intended to remove one or more superficial layers of the skin, the injection of collagen or other skin filling agent, the dermabrasion, injection of botulinum toxin or surgical methods such as "facelift". Recently, methods of treating the skin with light have appeared.

Such methods use, for example, a laser or a source of intense pulsed light.

The concept of photorejuvenation developed a few years ago aims to improve the heliodermia by non-ablative means, that is without removing the superficial layers of the skin and therefore without annoying side effects. Dr. Mac Daniel first showed that by using cold light sources such as LEDs (emitting from 0.01 to 2 Joules / cm2) one could regulate the fibroblast activity and induce the formation of procollagen (collagen type I) . At the same time, there was a significant reduction in Metalloproteinases type 1 (MMPI or collagenase). This concept has been confirmed by NASA's Dr. Wheland team.

Intense Pulse Light (IPL) is also a technology widely used in aesthetic care. It complements the action of lasers in the treatment of signs of aging such as photo-depigmentation and wrinkles. Flash lamps are high-intensity discharge lamps filled with a rare gas, xenon, for example. They work by converting stored electrical energy into intense bursts of radiant energy. The light emitted covers the ultraviolet, visible and infrared light spectrum regions, i.e. from about 350 nm to about 1200 nm. Unlike lasers, flash lamps are therefore polychromatic. This broad spectrum of the lamp allows to act simultaneously on different types of skin problem. Indeed, it has been determined that a given range of wavelengths can have a particular beneficial effect on the skin. It is then necessary to use filters allowing selection of the desired wavelength depending on the treatment envisaged. This particularity of flash lamps explains that their manipulation must be reserved for experienced practitioners.

Another disadvantage of flash lamps, as well as lasers, is the relatively large size of these devices.

In addition to the use of lasers or flashlamps, a technology has developed around the use of light-emitting diodes (LEDs) for the cosmetic and therapeutic treatment of the skin. Light-emitting diodes are electronic components that, when traversed by an electric current, emit low-frequency light. It emits a light that is considered cold because it does not produce heat. This characteristic is due to a lack of resistance present in other bulbs. LEDs fall into the category of LLLTs (Low Level Laser Therapy). They have the advantage of being inexpensive compared to lasers or flash lamps and, because of their lower light intensity, do not present any danger of burns or other injuries to the skin if the exposure is not correctly done.

Light-emitting diodes emit light in a spectrum that extends from visible to infrared. Some are said to be monochromatic but emit light whose wavelength is within a small spectrum corresponding to a given color of light. Others, such as white diodes, are polychromatic. It is therefore possible to use light-emitting diodes for the cosmetic treatment of the skin and to select them according to the result that it is desired to obtain.

One of the targets in the cosmetic treatment of wrinkles, as well as in the prevention of the appearance of wrinkles, is collagen. Collagen is a fibrous protein secreted by the fibroblasts of the connective tissue This protein ensures the cohesion of the connective tissue The appearance of the wrinkles is due, to a large extent, to the deterioration of the connective tissue and to the decrease with the age of the collagen synthesis by fibroblasts.

It is now known that exposing the skin to light can stimulate collagen synthesis or even prevent the deterioration of collagen present in the connective tissue. This is the case, for example, of light which corresponds substantially to the yellow light of the visible spectrum of light. One possible explanation is that at this wavelength range, the light flow can inactivate collagenase, an enzyme that degrades collagen.

But if the choice of a range of wavelengths is important for a treatment given by the light, it is also important to select the adequate light intensity and the duration of exposure of the area to be treated which will, in combination , to obtain a satisfactory result. Nevertheless none of the previously described solutions can treat the entire face (and not zone by zone, such as bridle, forehead, lip contour, resulting in a very long treatment time for the entire face ...) in a single application and offer a single very effective device to perform alone at home, without the intervention of a professional such as a cosmetic doctor, several types of skin care, both for to reduce the imperfections caused by acne, the tasks, the effects of aging, the effects of the sun, stress, pollution or fatigue on the skin.

Today the Applicant continues to innovate in this field of cosmetic skin care by having designed a cosmetic skin care device for the entire face in one application, in the form of a mask combining photomodulation and electrostimulation acting synergistically. for an optimal result, and a cosmetic process for the care of the skin of the face implemented by the device according to the invention, combining photomodulation and electrostimulation steps to increase the cellular renewal of the skin and / or the effectiveness cosmetic skin care and / or radiance and homogeneity of skin tone and / or endorphin secretion of the skin and / or firmness of the skin, and / or to prevent the appearance of wrinkles and / or the appearance of spots and / or the appearance of signs of fatigue of the skin and / or to reduce wrinkles and / or rosy skin tone and / or reduce the risk of and / or to regulate the sebum content of the skin and / or to reduce redness of the skin and / or skin imperfections and / or to have a detoxifying effect on the skin and / or an antipollution effect of the skin. the skin, said method being able to be carried out alone at home.
