摘要:
Systems and methods for revitalizing aging skin using electromagnetic energy that is delivered using a plurality of needles that are capable of penetrating the skin to desired depths. A particular aspect is the capability to spare zones of tissue from thermal exposure. This sparing of tissue allows new tissue to be regenerated while the heat treatment can shrink the collagen and tighten the underlying structures. Additionally, the system is capable of delivering therapeutically beneficial substances either through the penetrating needles or through channels that have been created by the penetration of the needles.
摘要:
Methods and devices for treatment of skin are disclosed. These methods and devices use electromagnetic radiation to create networks or patterns of treatment zones. The networks or patterns of treatment zones comprise at least four treatment zones, at least two of the treatment zones in the network or pattern are slanted at angles in the skin, and the treatment zones extend at least as deep as the dermal-epidermal junction of the skin. Producing intersecting treatment zones and/or overlapping treatment patterns can increase the effectiveness of the treatments. The devices comprise a hand piece operably coupled to a delivery element, wherein delivery of electromagnetic radiation through the device to a portion of skin produces a network or pattern of treatment zones. The use of these methods and devices results in tightening of the skin and/or improvement in the cosmetic appearance of wrinkles in the portion of skin treated.
摘要:
Disclosed are peptides that inhibit the enzymatic activity of tyrosinase, as well as formulations and methods for their use in the reduction of skin pigmentation, and methods of administering the inhibitory pep tides in a topical formulation. Preferred octapeptide sequences are internally rich in tryptophan and/or tyrosine or arginine. The present invention is further directed to kits and compositions containing the present peptides, and methods of treatment of conditions involving expression of tyrosinase, in which the present peptides are administered topically for the treatment of conditions involving melanocyte activity in the skin.
摘要:
Subjects treated with nonablative fractional photothermolysis (FP) have an intact stratum corneum, but can have microscopic lesions and vacuole formation within the epidermis. The vacuoles thus formed can trap dermal material and extrude it through the epidermis. Thus, FP can be used for the treatment of recalcitrant melasma, solar elastosis, and tattoos.

摘要:
Methods and compositions are provided for the differentiation and characterization of mammalian fibroblast from mesenchymal stem cells. The methods of the invention provide a means to obtain mesenchymal stem cell-derived fibroblast populations, e.g., seeded on a scaffold, which may be used in wound healing.
