  • Patent number: 9918944
    Abstract: A method of forming a membrane on a patch of skin using a gel, for the purpose of protecting the skin area or administering pharmacologically active substances to or through the skin area. The main ingredients of the gel are an alkyl acrylate crosspolymer such as Carbopol Ultrez 20 and a water soluble polymer such as polyvinylpyrrolidone (PVP). The gel may also contain other ingredients such as water, ethanol, antioxidants, lubricants, and neutralizers. The gel has the properties of being colorless and clear, low skin and nose irritability, easy to administer, fast membrane forming time, and removable by washing with water.

  • Publication number: 20080183250
    Abstract: Compositions, kits and methods are provided for restoring skin barrier function to skin of a subject after a medical or a cosmetic procedure. In general, a composition containing divalent cations such as calcium ions and/or magnesium ions in a physiologically acceptable medium can be used to treat, inhibit or prevent inflammation of skin post medical, demertological, or cosmetic procedure such as chemical peeling, laser skin resurfacing, microdermabrasion, plasma energy treatment, radiofrequency treatment, hair or vein removal or lightening, skin treatment using light energy or photofacial, thereby treating, inhibiting or preventing post-inflammatory hyperpigmentation of the skin or other skin disorders.

  • Patent number: 7300649
    Abstract: Compositions, kits and methods are provided for restoring skin barrier function to skin exposed to environmental elements and/or in a pathological condition. In general, divalent cations such as calcium ions and/or magnesium ions are included in a physiologically acceptable medium. In some embodiments, divalent cations are balanced with monovalent cations such as sodium and potassium ions at appropriate ratios in order to maintain the homeostasis of skin barrier. The compositions, kits and methods can be used as cosmetics, cosmeceuticals or pharmaceuticals for improving skin condition, and preventing or treating dermatological diseases and skin disorders.

  • Publication number: 20040266685
    Abstract: The invention relates to methods of treating diseases related to vasodilation, generally comprising administering to an individual an effective amount of a pharmaceutically active relaxin. Relaxin functions to increase both vasodilation and angiogenesis in males as well as females, and is therefore useful in treating a wide variety of diseases relating to vasoconstriction.
