  • Methods for treating skin lines and wrinkles and improving skin quality
    Publication number: 20100068232
    Abstract: Methods and compositions for improving skin quality are disclosed. The methods include applying a solution of about 20-30% pre-wetting agent, such as hyaluronic acid, and/or Botulinum toxin to a skin surface with concurrent particle-free dermabrasion treatment, such as particle-free microdermabrasion treatment. These methods lead to significant improvement in the treatment of skin aging. Compositions for improving skin quality are also disclosed. These compositions comprise a pre-wetting agent and a Botulinum toxin agent.

  • Method of amplifying a beneficial selective skin response to light energy
    Patent number: 7033349
    Abstract: A method of altering the appearance of a region of skin is disclosed. The method includes applying a sensitizing wavelength of light the region, and applying a treatment wavelength of light to the skin, wherein the treatment wavelength is a shorter wavelength than the sensitizing wavelength. The application of the sensitizing wavelength of light and the treatment wavelength of light results in a change in a physical property of the skin.
