Human skin color neural, or viral causes. The incidence worldwide is less than 1%. Individuals affected by vitiligo sometimes suffer psychological discomfort because of their appearance. Increased melanin production, also known as hyperpigmentation, can be a few different phenomena: Aside from sun exposure and hormones, hyperpigmentation can be caused by skin damage, such as remnants of blemishes, wounds or rashes. This is especially true for those with darker skin tones. The most typical cause of darkened areas of skin, brown spots or areas of discoloration is unprotected sun exposure. Once incorrectly referred to as liver spots, these pigment problems are not connected with
Alumina effect pigment applied to the pigment particles to adjust them to solvent-based and water-based coating systems. The pigments can be used in combination with many conventional pigments as well as with other effect pigments. Nearly unlimited styling possibilities are the result of these combinations. Alumina effect pigment An alumina effect pigment is a pearlescent pigment based on alumina (aluminium oxide). In the first step of the production process, AlO (Aluminium oxide) flakes with a very smooth surface are formed. The flakes are produced using a crystal growth process. They are formed in the corundum structure (α-AlO). The desired flake shape is achieved
