Definitions
- alkylamidothiazoles in cosmetic or dermatological preparations for the care of tattooed human skin and in particular for increasing the brilliance of tattoos on dark human skin
- the present invention relates to the use of alkylamidothiazoles in cosmetic or dermatological preparations for the care of tattooed human skin and in particular for increasing the brilliance of tattoos on dark human skin.
- a tattoo is an image or text that is applied to the skin with ink or other colored pigments.
- the color is usually pricked under the top layer of skin with the help of a tattoo machine through one or more needles, depending on the desired effect, and the image or text is drawn in the process.
- the process of tattooing is basically a puncturing of the skin, in which a dye is introduced into the skin at the same time as the skin is pierced.
- the color pigments are introduced into the middle layer of the skin, the dermis, and are deposited there, e.g. in / around the fibroblasts.
- a tattoo is usually easily recognizable on poorly pigmented skin. However, the more pigmented the skin, the more difficult it will be to recognize the contours of the tattoo. Multi-colored tattoos are often used, which, the darker the pigmentation of the corresponding skin area, are often only faintly perceptible. It was necessary to remedy this situation.

They can also serve as sunscreens.
- the melanocytes were cultured for a further 2 weeks (without changing the medium, so that the secreted melanin accumulated). After the two weeks, 10 ml of the respective supernatant in which the melanocytes secreted melanin were placed in each well of a 6-hole plate. A motif with different colored rectangles was printed out on a “Color Laser Transparency Film” (3M; CG3700). This motif was photographed through the plastic bowls filled with the protrusions on a light table (Kaiser Photo Technique, eVision ini.tial: hf) (Canon EOS-1 Mark IV with Canon Compact-Macro Lens EF 50 mm; ISO 100, f 9.0, 1/80, WB fluorescent).
- 3M Color Laser Transparency Film
- the images were analyzed with the aid of the “imagej” software and the RGB channels of the respective areas were evaluated.
- the RGB values were converted into Lab values (http://colormine.org/convert/rgb-to-lab).
- the comparison of the corresponding ⁇ E values between the images (thiamidol vs. untreated) shows that the color differences are always greater when the supernatant of the thiamidol-treated melanocytes is recorded than when the untreated melanocytes are recorded.
- nocytes Figures 1 and 2).
