37 results about "Stratum basale" patented technology

The stratum basale (basal layer, sometimes referred to as stratum germinativum) is the deepest layer of the five layers of the epidermis, the outer covering of skin in mammals. The stratum basale is a single layer of columnar or cuboidal cells. The cells are attached to each other and to the overlying stratum spinosum cells by desmosomes and hemidesmosomes. The nucleus is large, ovoid and occupies most of the cell. Some basal cells can act like stem cells with ability to divide and produced new cells, whereas others serve to anchor the epidermis glabrous skin (hairless), and hyper-proliferative epidermis (from a skin disease).

Skin lightening composition

InactiveUS20160243015A1Reduced activityAbsence of hyperpigmentationCosmetic preparationsToilet preparationsIrritationSkin color
Desired skin colour is a major unmet consumer need around the world and especially in Asia. Consumers particularly desire even skin colour, absence of age spots (solar lentigines), absence of hyperpigmentation and lighter overall skin tone. One solution is to use biological actives that reduce the activity of melanocyte cells in skin. These cells, present in the basal layer of the epidermis, make the dark coloured pigment melanin and export it, in small export vesicles called melanosomes, to the neighbouring keratinocytes. It is well described in the literature that compounds which reduce melanin synthesis when topically applied to the skin will reduce skin darkness over time and can generate a more even skin tone. Tyrosinase is a very popular target for the regulation of melanocyte pigment production. However effective inhibitors of tyrosinase are bedevilled by safety issues causing, for example, melanocyte cell death, permanent depigmentation, irritation and allergic reactions. Often effective inhibitors kill melanocytes (for example hydroquinone) or cause sensitisation reactions. There is therefore a great need for safe and effective inhibitors of skin pigment production that work through an alternative safe mechanism. The inventors have observed that selected compounds of the same generic structure: or a salt thereof; wherein R1, R2, R3, R4 and R5 may be independently selected from the group consisting of —H, -halide, and methyl, ethyl, propyl, iso-propyl, butyl, and t-butyl moieties, inhibit melanin production in Melanoderms™.
