  • Patent number: 11590331
    Abstract: In the preferred embodiment of the present invention, a patch of dissolving microneedles loaded with active ingredients to be applied to skin for treating skin conditions is provided. As seen in FIG. 1, the dissolving microneedle patch (10) comprises a substrate (12) and a plurality of microneedles (14) which extends from the substrate. The dissolving microneedle patch (10) is made of a matrix material and at least one active ingredient such as a corticosteroid, namely triamcinolone (TAC). The matrix material is made of bio-compatible materials such as hyaluronic acid (HA), polyvinylpyrrolidone (PVP), or mixture of them, which dissolve rapidly when they are in contact with the inner skin. The active ingredient is loaded onto individual patches with the desirable dosage ranging from 0.01 mg-1.0 mg.

  • Publication number: 20230059938
    Abstract: There is provided a pharmaceutical formulation comprising an anticholinergic agent and a ternary solvent comprising 5% to 15% v/v glycol, 60% to 70% v/v alcohol and 5% to 20% v/v water. There is also provided a method of preparing the pharmaceutical formulation as disclosed herein, comprising the step of mixing the anticholinergic agent to a mixture containing alcohol, glycol, water, humectant and pH buffering agent at room temperature. There is also provided a method of inhibiting non-pathological body malodour in a mammal. There is also provided a method of treating apocrine secretion causing odour and reduction of microbial overgrowth in a mammalian subject, and uses of a pharmaceutical formulation.

  • Patent number: 10856799
    Abstract: The present disclosure generally relates to an automated method and system for generating a three-dimensional (3D) representation of a skin structure of a subject. The method comprises: acquiring a plurality of two-dimensional (2D) cross-sectional images of the skin structure, specifically, using optical coherence tomography (OCT) technique; computing a cost for each 2D cross-sectional image based on a cost function, the cost function comprising an edge-based parameter and a non-edge-based parameter; constructing a 3D graph from the 2D cross-sectional images; and determining a minimum-cost closed set from the 3D graph based on the computed costs for the 2D cross-sectional images, wherein the 3D representation of the skin structure is generated from the minimum-cost closed set.
