Abstract:
A method for forming an opening in a region of the stratum corneum of a patient comprising the steps of:(a) providing a source of light having a wavelength of from about 930 nm to about 1040 nm; and(b) exposing said region of the stratum corneum of said patient to said source of light for a period of time sufficient to form an opening in the stratum corneum, wherein exposure of said region of the stratum corneum to said source of light is ceased when an amount of interstitial fluid occupies said opening in the stratum corneum, said amount of interstitial fluid having a surface that causes light from said source of light to scatter, said scattered light having a scatter intensity, said amount of interstitial fluid being sufficient to cause said scatter intensity of light reflected from said surface of said interstitial fluid occupying said opening in the stratum corneum to differ from the scatter intensity of light reflected from a region of the stratum corneum that is substantially free of interstitial fluid.
