Embodiment Construction

[0177] device

[0178] For example, the method according to the invention is carried out by means of a device for applying light to the skin comprising at least one light source capable of emitting quasi-monochromatic light of artificial origin at a first wavelength D (eg figure 1 shown), and one or more exit windows for the emitted light.

[0179] like figure 2 As shown, the device can also be configured to emit a second quasi-monochromatic light of artificial origin having a wavelength between 700 nm and 1000 nm, preferably between 800 nm and 900 nm (e.g. about 870 nm). The wavelength peak R. The light is red light or infrared light. The light source of red light or infrared light may be the same as or different from the light source supporting the above-mentioned first light. The device may include a single light source configured to emit two different quasi-monochromatic lights. As a variant, the device can comprise two different light sources, each of which emits...

Abstract

The present invention relates to a method for the cosmetic (non-therapeutic) treatment of oily skin, said method comprising the steps of: a) exposing said oily skin to a first quasi-monochromatic light of artificial origin, the dominant wavelength of which is a peak between 300nm and 700nm, better between 400nm and 600nm, even better between 560nm and 620nm, especially about 590nm, and b) applying the cosmetic composition to said oily skin, the Composition comprising at least 1% by weight of hollow particles, and preferably 2% to 6% by weight, of hollow particles which are hydrophobic silica aerosols, relative to the total weight of said composition Glue particles.

Description

technical field [0001] The present invention relates to the cosmetic (ie, non-therapeutic) treatment of oily skin. Background technique [0002] The skin is rich in sebaceous glands and is constantly renewed. The production of sebum is a normal phenomenon that is useful to the skin and hair. Sebum is normally a substance used to moisturize the epidermis. Sebum is a natural product of the sebaceous glands that are appendages of the pilosebaceous unit. Sebum is essentially a more or less complex mixture of oils. Sebum protects the skin as well as the scalp and gives shine to the hair by lubricating the cuticle. [0003] Unfortunately, excessive secretion of sebum, or seborrhea, can lead to aesthetic disturbances. Thus, excessive secretion of sebum can lead to oily skin with a shiny or shiny appearance, and can also contribute to an oily dandruff condition of the scalp or the appearance of oily dandruff. Excessive sebum production is also accompanied by increased pore siz...
