Definitions

  • the present invention relates to the field of cosmetic products, more particularly intended for the prevention and/or treatment of cutaneous blackheads.
  • It also relates to a cosmetic method, in particular a non-therapeutic method, comprising the application, to the skin to be treated, of a composition containing at least one active principle in accordance with the invention.
  • Cutaneous blackheads in particular on the face, concern all skin typologies. Due to their black, indeed even brown, color, they are highly visible, all the more so on lightly pigmented skin, and, as such, are generally regarded as unattractive and thus undesirable.
  • a cutaneous blackhead results from the process of comedogenesis which affects pilosebaceous units of sebaceous follicle type, which are distributed predominantly on the face.
  • comedogenesis causes distension of the hair canal, sebum retention and excessive comification of the pilosebaceous duct.
  • Hypercornification results in sebum retention and in the accumulation of cell debris.
  • Keratin and keratotic plugs are clusters of corneocytes, in particular clusters of proteins. They are colourless, while blackheads are, as their name suggests, black or dark brown. As such, while keratin plugs may be present in blackheads, they are not responsible for the black or brown colour of the comedones.
  • JP 2018/021084 which relates to a liquid cosmetic cleansing composition in the form of an emulsion for extracting the proteins which adhere to the skin.
  • Solutions are also already available for treating blackheads. These solutions generally target accumulation of cell debris and sebum retention by an action of desquamation of the surface of the open comedo.
  • Some of these solutions consist of physical methods based on the use, for example, of comedo suction device, of comedo extractor or of self-adhesive patches to be removed. For obvious reasons, these methods have an aggressive nature with regard to the skin, are not painless and are capable of generating unattractive skin irritation or red marks.
  • the present invention results more particularly from the characterization by the inventors of novel active principles which are particularly effective with regard to blackheads and which advantageously prove to be devoid of the abovementioned disadvantages.
  • the present invention relates to the cosmetic use of at least one Ci 8 fatty acid or alcohol chosen from isostearic acid, oleyl alcohol and their mixtures for dissolving all or part of the constituent lipids of cutaneous comedones and/or blackheads.
  • the cosmetic use of at least one Cis fatty acid or alcohol chosen from isostearic acid, oleyl alcohol and their mixtures proves to be very particularly effective in preventing the appearance of cutaneous blackheads and/or removing cutaneous comedones and blackheads.
  • isostearic acid and/or oleyl alcohol is/are employed in combination with at least one fatty acid chosen from oleic, linolenic, linoleic, behenic, arachidonic and stearic acid and in particular with at least oleic acid.
  • isostearic acid and oleyl alcohol prove to be capable of dissolving lipid substances constituting cutaneous comedones and blackheads and thus are shown to be particularly effective in preventing the appearance of blackheads and/or removing these blackheads.
  • the present invention relates to a cosmetic method for dissolving all or part of the constituent lipids of cutaneous comedones and/or blackheads, comprising the application, to the skin to be treated, of at least one Cis fatty acid or alcohol chosen from isostearic acid, oleyl alcohol and their mixtures.
  • the cosmetic method in accordance with the invention is of use in preventing the appearance of cutaneous blackheads and/or removing cutaneous comedones and blackheads.
  • the cosmetic uses and methods considered according to the invention are nontherapeutic.
  • the uses and methods considered herein for dissolving all or part of the constituent lipids of cutaneous comedones and/or blackheads are exclusively cosmetic.
