    • A method for measuring skin absorbability of a substance, which includes measuring the amount of the substance which is penetrated into hair follicles; and using the resultant data as an index representing the amount of the substance which is absorbed through skin pores, to thereby determine the amount of the substance absorbed through skin pores and a method for measuring skin absorbability of a substance, which includes bringing the substance into contact with a first surface of a thin film that mimics the skin surface layer, a second surface of the film being brought into contact with artificial sebum; and evaluating the sebum transferability of the substance by using the degree of transfer of the substance to the artificial sebum as an index, are disclosed. A kit for performing the measurement method of the present invention is also disclosed.

    • A device and method is disclosed for permanent or semi-permanent removal of hair through the activation of microparticles introduced into hair follicles. Microparticles are incorporated into a composition that is topically applied to the skin. These microparticles containing or consisting of chromophores or chemically activated molecules are of a variety of shapes and sizes. Microparticles are within a size range of 1 micron to 70 microns, and preferably between 10 and 50 microns. Microparticles of this size and variety of shapes enter hair follicles on all areas of the skin without entering other areas of the skin, such as the stratum corneum or sweat gland channels. Treatment of the skin with electromagnetic radiation, ultrasonic radiation or chemical means activates the chromophore or chemically activated compounds, thus destroying the hair follicle without damaging other areas of the skin. In another embodiment, microparticles further contain nanoparticles released further into the hair follicle by use of a solvent or other method, allowing chromophores or chemically activated molecules to penetrate deeper into the follicle and avoid structures such as the sebaceous gland.
    • 公开了通过引入毛囊的微粒的活化来永久或半永久性去除毛发的装置和方法。 将微粒掺入局部施用于皮肤的组合物中。 含有或由发色团或化学活化分子组成的这些微粒具有各种形状和尺寸。 微粒的尺寸范围为1微米至70微米,优选为10至50微米。 这种尺寸和各种形状的微粒在皮肤的所有区域都进入毛囊,而不会进入皮肤的其他区域,例如角质层或汗腺通道。 用电磁辐射,超声辐射或化学方法治疗皮肤会激活发色团或化学活化的化合物,从而破坏毛囊而不损害皮肤的其他部位。 在另一个实施方案中,微粒还包含通过使用溶剂或其它方法进一步释放到毛囊中的纳米颗粒,使得发色团或化学活化分子能够更深地渗入毛囊并避免诸如皮脂腺的结构。

    • In a method for non-therapeutic or therapeutic photodynamic treatment of a skin target area, a photosensitizer fluid incorporating a photosensitizing agent or a precursor for a photosensitizing agent is delivered to the target area, the photosensitizing agent having at least one absorption wavelength in a wavelength range higher than 400 nm. The target area is then exposed to light energy in a range of wavelengths comprising at least one absorption wavelength of the photosensitizing agent, the light energy being supplied to the target area in the form of at least one light pulse producing in the target area an accumulated energy density sufficient for photodynamic activation of the photosensitizing agent. The photosensitizing agent or precursor is incorporated in the photosensitizer fluid with a concentration in the range from 0.1 to 2.0 % preferably from 05 to 1.0 %, and the photosensitizer fluid is delivered to the target area in the form of a number of repeated spray doses during an overall delivery time ranging from 0.25 to 8 hours. The method can be applied to cosmetic treatments for skin rejuvenation, reduction of wrinkles, treatment of telangiectasia or removal of hair as wells a medical treatment of dermatologic diseases such as acne vulgaris, acne scars, rosacea, psorieasis, actinic keratoses, basal cell carcinoma, Bowen's disease or eczema.
    • 在用于非治疗或治疗光动力治疗皮肤靶区的方法中,将含有光敏剂或光敏剂的前体的光敏剂流体输送到目标区域,所述光敏剂具有至少一种波长的吸收波长 范围高于400 nm。 然后将目标区域暴露于包括光敏剂的至少一个吸收波长的波长范围内的光能,光能以在目标区域中产生的至少一个光脉冲的形式被提供给目标区域,累积 能量密度足以使光敏剂的光动力激活。 将光敏剂或前体掺入光敏剂流体中,浓度范围为0.1至2.0%,优选为05至1.0%,并且将光敏剂流体以多次重复喷雾剂量的形式递送至目标区域 整体交货时间为0.25至8小时。 该方法可应用于皮肤复原,减少皱纹,治疗毛细血管扩张或去除毛发的美容治疗,例如寻常痤疮,痤疮疤痕,红斑痤疮,银屑病,光化性角化病,基底细胞癌等皮肤科疾病的治疗, 鲍文氏病或湿疹。
