Definitions

  • the present invention relates to a cosmetic kit and method. More particularly it relates to a kit comprising a metal coated pad for use as a skin exfoliant.
  • Normal healthy skin is composed of many layers of cells which comprise the epidermis. These cells are generated in distinct germinal layers - the stratum basale and the stratum spinosum. Layers of epidermal cells form continuously throughout life, and as these successive layers pass towards the outer surface of the skin over a period of many days, they undergo a maturation process during which they generate within their cellular substance the protein keratin. This substance has a tough, horny consistency and is impervious to water. Eventually these cells become filled with keratin and die, to form the tough outermost mechanical barrier of the skin - the stratum corneum. The individual cells filled with keratin are now referred to a squames. It is this horny layer that varies in thickness from one region of the body to the next according to the level of wear and tear the skin is subjected to.
  • Sheading of dead keratinised skin cells is a natural process called desquamation.
  • Some disease processes and inflammatory conditions, and irritations to the skin caused by mechanical, chemical and thermal stimuli and sunlight, and even normal repair and healing, can cause a proliferation of the epidermal cells and result in an excessive thickening of the stratum corneum - a process referred to as hyperkeratosis.
  • This thickening of the horny outer layer can make the skin feel uncomfortable and appear of poor colour.
  • the skin also produces natural secretions such as sweat and fatty substances that help prevent bacterial and fungal infections.
  • One such secretion, sebum - an oily secretion helps to waterproof both the skin and hair.
  • An excessive build up of this substance can lead to the formation of comedones - commonly referred to as "Black heads", which can mar the appearance of the skin, and can be troublesome to remove, leading to localised areas of inflammation - so called spots and pimples.
  • Excess keratinised squames can be removed from the surface of the skin by rubbing the stratum corneum with an abrasive material. This process of removing the keratinised layer from the surface of the skin is known as exfoliation.
  • Many materials and substances are available in cosmetic preparations for the removal of these keratinised squames, by way of exfoliation.
  • Pumice stone is one such abrasive material that has been used traditionally as an exfoliant.
  • Other exfoliant preparations comprise fine abrasive particles such as ground nut kernal, silicates and microscopic dense plastic particles in liquid suspension. Vegetable matter and textiles with abrasive textures have also been used for this purpose.
  • Exfoliation helps to remove this surface layer of keratinised cells that is perpetually colonised by bacteria and fungi. This process is commonly performed as part of routine skin cleansing and helps to minimise the build up of an excessively thick keratinised layer, and can provide the skin with a smooth and blemish free appearance.
  • Exfoliant abrasives are often delivered in an aqueous suspension or within a paraffin or natural wax based emulsion. These preparations are formulated by manufacturers to minimise skin irritation and allergic skin reactions.
  • a pad having a coating of metal particles in particular a pad of material woven from nylon fibres having a coating of silver particles, is particularly advantageous for use as an exfoliant.
  • the present invention provides a kit for use in a method of exfoliating skin, which comprises a pad having a coating of particles of a metal selected from silver, gold and platinum, packaging material and instructions for use of the pad as an exfoliant.
  • the present invention provides the cosmetic use of a pad having a coating of particles of a metal selected from silver, gold and platinum as a skin exfoliant.
  • the present invention provides a method for exfoliating an area of the skin of a subject, which comprises rubbing the area of skin with a pad having a coating of particles of a metal selected from silver, gold and platinum. It has been observed that facial skin that has been exfoliated using the metal coated pad has a smooth texture, an even colouration and an increased tonus. Skin on which the pad has been used daily or intermittently for a period of several months appears healthy. The improvement in the condition of facial skin in adolescents was observed to be particularly good. By simply rinsing a pad with water under a tap after each use, it was found that the pad could be used without loss of efficacy and without developing any odour for more than four months.
  • the metal particles coating the pad may self-disinfect the pad, and also deposit on the skin. It is known that particles of certain metals possess antibacterial and antifungal action.
  • the metal may be elemental silver, gold or platinum, or an alloy of silver, gold and/or platinum. In one embodiment of the invention, the metal is silver.
  • the skin may conveniently be rubbed with the pad in the presence of a lubricant.
  • a preferred lubricant is water.
  • the pad is washed with water after use, and is then reused. It has been found that pads treated in this way may be used repeatedly, for example daily, for periods of up to four months or longer, without loss of effectiveness and without developing any odour.
  • the subject to which the method is applied may be any subject requiring exfoliation, for example a human or a non-human animal, such as a companion animal.
  • the subject may be a human child (aged for example up to 10 years), adolescent (aged, for example, from 10 to 20 years) or adult, male or female. Particularly good results have been obtained where the human subject was an adolescent.
  • the area of skin may be any area of skin on the subject. It is preferably the face, for example the cheeks or the nose. - A -
  • the pad may conveniently be rubbed on the area of skin for from about 0.5 to about 2 minutes.
  • the method may be repeated, for example once or twice daily, such as for up to one week, one month, two months, three months, four months or longer.

  • the metal (such as silver) particles have been formed by vapour deposition, such as under vacuum by Ion Beam Assisted Deposition - IBAD or Ion Beam Implantation or by electrolytic deposition. These processes produce an even distribution of tightly adherent nano-crystals of the metal.
  • Suitable methods of forming the metal particles by vapour deposition are well known in the art, for example in the manufacture of metal (such as silver) coated materials for use as wound dressings.
