Definitions

  • the present disclosure generally relates to a cosmetic package for applying a product including a cosmetic, care or pharmaceutical product, onto keratinous substrate such as skin, lips, eyelashes, under eyes, eyebrows, eyelids, cheeks, nails or any other part of the body. More particularly, the present disclosure relates to a cosmetic package comprising an application member that offers a thermal effect on the skin of a user upon application.
  • Some cosmetic, care or pharmaceutical compositions may include therapeutic substances, such as topical anesthetics, analgesics, fragrances, menthol, or other substances that provide a soothing or stimulating sensation when applied onto the skin of a user.
  • heat transfer treatments e.g., application of heat and/or cold
  • heat transfer treatments are also known to provide a soothing or stimulating sensation when applied onto the skin of a user. These heat transfer treatments are done separately after applying the cosmetic composition onto the skin.
  • Metal applicators are used to transfer heat or cold sensation when a cosmetic composition is applied onto the skin. This is the case in particular for eye contour products for which manufacturers of cosmetic products consider that providing a cold effect on the skin when applying the composition allows to reduce wrinkles, remove under-eye bags, attenuate signs of fatigue, firm up or tighten the skin and/or make a person look momentarily younger. Such benefits are linked to the effect of momentary constriction of blood vessels, resulting in decreased blood flow when the skin comes into contact with the composition providing a cold sensation upon application.
  • an applicator member which is capable of not only transferring hot or cold sensation at the time of application of the composition to the skin but also capable of uniformly spreading the composition on the skin.
