Description

Description

Title of the invention: Ultra portable method and device for anti-wrinkle and anti-puffiness and / or concealer treatment of the eye contour by photomodulation, micro-currents, iontophoresis and reverse iontophoresis [0001] The present invention relates an anti-aging cosmetic treatment device (wrinkles, redness) and anti-puffiness and / or concealer of the skin on the area around the eye by photomodulation, micro-currents, iontophoresis and / or reverse iontophoresis as well as 'a method implementing such a device.

Maintaining a youthful appearance is nowadays a constant concern. Over time, and in particular chronological and / or photo-induced aging, the skin undergoes numerous modifications and degradations which result, at the tissue level, in 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 down or dysregulation of various cellular metabolisms, such as those involved in the balance of the barrier function or involved in melanogenesis. At the cellular level, aging is thus reflected by an alteration in the physiology or metabolism of the main cell types such as the fibroblasts of the dermis, keratinocytes of the epidermis, and also melanocytes.

[0003] Skin aging results from two distinct and independent processes which involve intrinsic or extrinsic factors. Intrinsic or chrono-biological aging corresponds to normal or physiological aging linked to age.

Intrinsic aging results in particular in a slowing down of the renewal of the cells of the epidermis and the appearance of fine wrinkles or fine lines. In the dermis, the biosynthesis of macromolecules such as collagen decreases with age, changing the mechanical properties of the dermis, resulting in sagging skin, one of the clinical signs of aging.

Extrinsic aging corresponds to aging generally caused by the environment and more particularly corresponds to photoaging due to exposure to the sun. Photo-induced skin aging, that is to say caused by exposure to the sun, is also called photoaging or heliodermia. Photo-aging is the result, in the dermis, of the breakdown of collagen fibers, notably resulting in clinical alterations such as thick wrinkles and the formation of soft, tanned skin. The aging of the skin is therefore accelerated by chronic exposure to UVs.

There are thus a large number of so-called “anti-aging” cosmetic treatments intended to prevent and / or treat aging, in particular photoaging and their signs, in particular to prevent the appearance of wrinkles and to reduce so visible wrinkles already present, but also reduce or eliminate age spots (aging). These cosmetic treatments include, for example, the regular application of so-called anti-wrinkle lotions or creams, “peels” intended to remove one or more surface layers of the skin, the injection of collagen or other agent. skin filling, dermabrasion, botulinum toxin injection or even surgical methods such as "lifting".

Recently, methods of treating the skin with light have appeared. [0008] 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 heliodermia by non-ablative means, that is to say without removing the surface layers of the skin and therefore without annoying side effects. Dr. Mac Daniel was the first to show that using cold light sources such as LEDs (emitting 0.01 to 2 Joules / cm2) could regulate the activity of fibroblasts and induce the formation of procollagen (collagen type I) . At the same time, a significant reduction in type 1 metalloproteinases (MMPI or collagenase) was observed. This concept was confirmed by the team of Dr. Wheland of NASA.

Intense pulsed light (Intense Pulse Light or IPL, also called flash lamp) is 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 regions of the ultraviolet, visible and infrared light spectrum, that is to say from 350 nm to about 1200 nm. Unlike lasers, flash lamps are therefore polychromatic. This broad spectrum of the lamp makes it possible to act simultaneously on different types of skin problem. Indeed, it has been determined that a given wavelength range can have a particular beneficial effect on the skin. It is then necessary to use filters allowing the selection of the desired wavelength according to the treatment envisaged. This peculiarity of flash lamps explains that their handling should be reserved for experienced practitioners.

Yet another drawback of flash lamps, as well as lasers, is the relatively large size of these devices.

As an alternative to the use of lasers or flash lamps, 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 which, when passed through 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 an absence of resistance present in the other bulbs. LEDs fall into the LLLT (Low Level Laser Therapy) category. They have the advantage of being inexpensive compared to lasers or flash lamps and, because of their lower light intensity, do not present a danger of burns or other injuries to the skin if the exposure is not correctly performed.

The light emitting diodes emit light in a spectrum which extends from visible to infrared. Some are said to be monochromatic but emit light whose wavelength is included in a narrow 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 which 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 connective tissue fibroblasts This protein ensures the cohesion of connective tissue The appearance of wrinkles is due, in large part, to the deterioration of connective tissue and to the decrease with age synthesis of collagen by fibroblasts.

It is now known that exposing the skin to light can stimulate the synthesis of collagen 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 flux makes it possible to inactivate collagenase, an enzyme which degrades collagen.

But if the choice of a range of wavelengths is important for a treatment given by light, it is also important to select the appropriate light intensity and the duration of exposure of the area to be treated which will allow , in combination, to obtain a satisfactory result.

The Applicant had already been able to demonstrate in patent FR2917299 that a cosmetic treatment of the skin with a device allowing the delivery of a light source emitting light in a spectrum of wavelengths between 590 and 598 nm, for a light intensity between 8000 and 12000 millicandelas (mcd), a frequency of the light pulses of approximately 2.5 Hz and a duration of each light pulse of approximately 1 ms allowed an action of prevention and reduction of wrinkles.

Today the Applicant continues to innovate in this field of cosmetic treatment of the skin by having designed a device specific to the area around the eye, making it possible to select:

-Either an anti-wrinkle program allowing the prevention and reduction of wrinkles by stimulation of the synthesis of collagen by fibroblasts, but also the reduction of redness of the skin. This cosmetic treatment includes photomodulation associated with a micro-current and iontophoresis treatment;

- Or an anti-puffiness and / or concealer program allowing the prevention and reduction of bags under the eyes. This cosmetic treatment includes photomodulation associated with a treatment by micro-current and reverse iontophoresis.
