  • Publication number: 20120271219
    Abstract: A method for regulating the condition of mammalian skin by the steps of applying a first personal care composition to an area of skin where regulation is desired. The first personal care composition contains a gel composition. In another step energy is delivered to the dermis to heat collagen in the dermis such that the heated collagen in the dermis heats the epidermis and stratum corneum until the stratum corneum reaches an external temperature of from about 37° C. to about 48° C. The energy delivery to the dermis is then controlled to maintain the temperature of the stratum corneum in the range of from about 37° C. to about 48° C.

  • Publication number: 20120270743
    Abstract: A gene panel comprising genes regulated in mammalian skin in response to generation of a radio frequency current in a tissue volume of the mammalian skin sufficient to heat the tissue volume to a treatment temperature, wherein at least one gene is selected from Table 1 or Table 2 and at least one gene is selected from Table 3. Further there is a method for providing a benefit to mammalian skin, the benefit comprising inducing collagen formation and/or dermal remodeling in a dermal layer of the mammalian skin in the absence of a skin-damaging inflammatory cytokine response, the method comprising generating a radio frequency current in a tissue volume of the mammalian skin for a treatment cycle sufficient to heat the tissue volume to a treatment temperature while avoiding an upregulation in expression of genes listed in Table 3.

  • Publication number: 20030170846
    Abstract: The present invention relates to enzyme variants having decreased immunogenicity relative to their corresponding wild-type enzymes. More particularly, the present invention relates to enzyme variants having a modified amino acid sequence of a wild-type amino acid sequence, wherein the modified amino acid sequence comprises a substitution of one or more amino acid positions with at least one D-amino acid. The invention further relates to mutant genes encoding such enzyme variants and cleaning and personal care compositions comprising such enzyme variants.

  • Publication number: 20030157088
    Abstract: Leave-on personal care compositions comprising a stabilized enzyme, at least 30% water, less than 5% of an earth alkali metal salt, and an enzyme inhibitor having an inhibition constant (Kl) from 10 nanomolar (nM) to 25,000 nM. Also, a method of providing a skin care benefits, e.g. skin feel and/or skin appearance, preferably skin moisturization, skin softness, and/or skin smoothness, comprising topically applying a safe and effective amount of the inventive compositions described herein to skin in need of such a skin care benefit. Further, a method of providing a consumer with a leave-on enzyme-containing personal care product, wherein the enzyme is inhibited and inactive on shelf, but is active on skin without the need for a separate re-activation step, preferably wherein the leave-on enzyme-containing personal care product comprises a one of the inventive compositions described herein.
