Abstract
The invention relates to a patch for application to the skin. The patch comprises: a reflecting layer that reflects the infrared radiation released by the human body, and between said reflecting layer and said face for application to the skin: a matrix made of a material having self-adhesive properties and comprising at least an acrylic or vinyl polymer whose adhesive properties increase with temperature over the range 20° C. to 40° C.; and in said matrix at least one active substance having an effect on the skin.
Claims19
A patch having a face for application to the skin, the patch comprising:
- a reflecting layer that reflects infrared radiation released by the human body towards the skin, and between said reflecting layer and said face for application to the skin:
- a matrix made of a material having self-adhesive properties and comprising at least an acrylic or vinyl polymer whose adhesive properties increase with temperature over the range 20° C. to 40° C.;
- and
- in said matrix at least one active substance having an effect on the skin.
A patch having a face for application to the skin, the patch comprising:
- a reflecting layer that reflects infrared radiation released by the human body towards the skin, and between said reflecting layer and said face for application to the skin:
- a matrix made of a material having self-adhesive properties and comprising at least an acrylic or vinyl polymer whose adhesive properties increase with temperature over the range 20° C. to 40° C.;
- and
- in said matrix at least one active substance having an effect on the skin;
- said matrix and said reflecting layer being permanently attached.
A patch having a face for application to the skin, the patch comprising:
- a reflecting layer that reflects infrared radiation released by the human body towards the skin, and between said reflecting layer and said face for application to the skin:
- a matrix made of a material having self-adhesive properties and comprising at least an acrylic or vinyl polymer whose adhesive properties increase with temperature over the range 20° C. to 40° C.;
- and
- in said matrix at least one active substance having an effect on the skin;
- said matrix comprising a permeable structure in the vicinity of said face for application to the skin.
A patch having a face for application to the skin, the patch comprising:
- a reflecting layer that reflects infrared radiation released by the human body towards the skin, and between said reflecting layer and said face for application to the skin:
- a matrix made of a material having self-adhesive properties and comprising at least an acrylic or vinyl polymer whose adhesive properties increase with temperature over the range 20° C. to 40° C.;
- in said matrix at least one active substance having an effect on the skin;
- and
- said reflecting layer consisting of a gold coating.
A patch having a face for application to the skin, the patch comprising:
- a reflecting layer that reflects infrared radiation released by the human body towards the skin, and between the reflecting layer and said face for application to the skin:
- a matrix made of material having self-adhesive properties and comprising at least an acrylic or a vinyl polymer whose adhesive properties increase with temperature over the range 20° C. to 40° C.;
- in said matrix at least one active substance having an effect on the skin;
- and
- said reflecting layer consisting of a silver coating.
A patch having a face for application to the skin, the patch comprising:
- a reflecting layer that reflects infrared radiation released by the human body towards the skin, and between said reflecting layer and said face for application to the skin:
- a matrix made of a material having self-adhesive properties and comprising at least an acrylic or vinyl polymer whose adhesive properties increase with temperature over the range of 20° C. to 40° C.;
- in said matrix at least one active substance having an effect on the skin;
- and
- said reflecting layer consisting of an aluminum coating.
