Cell Renewal Efficiency Test (Proliferation)
Many cosmetic products are produced for skin aging, which is a complex biological process caused by internal and external factors. Cosmetic products offered for sale with claims such as anti-aging and cell renewal go through different test processes for proof. Decreased skin barrier levels, also known as Langerhan cells, are a major cause of aging. For this reason, the main purpose of anti-aging cosmetic products is to reproduce Langerhan cells.
Autophagy is the process of cleaning the damaged cells of the body in order to obtain new and healthier cells. Formulas that trigger autophagy are also produced in cosmetic products produced with the claim of cell renewal.
According to EU Commission 655/2013, the claims stated on the label must be supported by test reports. In cosmetic products, studies are carried out on volunteers with the Cell Renewal Efficiency Test (Proliferation). Depending on the test results, "Cell Renewal Effect" can be claimed in cosmetic products.
