Melanin is a chromophore that exists in the human epidermal layer of skin responsible for protection from harmful UV radiation. When melanocytes are stimulated by solar radiation, melanin is produced. [7] Melanin is one of the major absorbers of light in some biological tissue (although its contribution is smaller than other components).
The peptides inside mimic the those within the skin to keep the eye area plump and smooth. In true Skinceuticals fashion, it also offers a host of other benefits, like fighting dark circles and ...
Cell-penetrating peptide facilitated translocation is a topic of great debate. Evidence has been presented that translocation could use several different pathways for uptake. In addition, the mechanism of translocation can be dependent on whether the peptide is free or attached to cargo.
The melanocyte-stimulating hormones, known collectively as MSH, also known as melanotropins or intermedins, are a family of peptide hormones and neuropeptides consisting of α-melanocyte-stimulating hormone (α-MSH), β-melanocyte-stimulating hormone (β-MSH), and γ-melanocyte-stimulating hormone (γ-MSH) that are produced by cells in the pars intermedia of the anterior lobe of the pituitary ...
Creatine peptides promote the release of hormones that influence one's exercise performance, muscle recovery and body composition, which is why some athletes are drawn to the amino acids.
There are a handful of skincare ingredients that you’ll find on the labels of many of your go-to products, including retinol , vitamin...
[6]) and sexual behavior, while α-MSH secreted from the intermediate lobe of the pituitary regulates the movement of melanin produced from melanocytes in skin. ACTH is a peptide hormone that regulates the secretion of mainly glucocorticoids from the cells of the zona fasciculata of the adrenal cortex.
Human skin is a very impermeable membrane that protects the body from ingress of harmful substances and prevents water loss from underlying organs. However, this seriously limits the use of skin as a site for drug administration. One of the approaches to facilitate transdermal drug delivery is the use of penetration enhancers. Many different ...
