Cosmeceuticals represent a marriage between cosmetics and pharmaceuticals. There are numerous cosmeceutically active products which can be broadly classified into the following categories: antioxidants, oligopeptides, growth factors and pigment lightning agents. Much attention has been focused on the tripeptides such as Gly-His-Lys (GHK) and Gly-Gly-His (GGH) and their copper complexes, which have a high activity and good skin tolerance. Recent data suggested their physiological role in process of wound healing, tissue repair and skin inflammation. The mechanism of anti-inflammatory properties of these peptides is not clear. The aim of the study was evaluation of influence of two peptides GGH. GHK and their copper complexes and saccharomyces/copper ferment (Oligolides Copper) on secretion of pro-inflammatory IL-6 in normal human dermal fibroblasts NHDF cell line. IL-6 was evaluated using the ELISA kit. GGH, GHK, CuCl2 and their copper complexes decreased TNF-alpha-dependent IL-6 secretion in fibroblasts. IL-6 is crucial for normal wound healing, skin inflammation and UVB-induced erythema. Because of the anti-inflammatory properties, the copper-peptides could be used on the skin surface instead of corticosteroids or non-steroidal anti-inflammatory drugs, which have more side effects. Our observations provide some new information about the role of these tripeptides in skin inflammation.
In general, lichen planus is not a harmful or fatal disease. It usually goes away by itself in time, but can persist for a long time, running into years, and this varies from patient to patient. The presence of skin lesions is not constant and may wax and wane over time. Oral lesions tend to last longer than those of the skin. Furthermore, even after going away completely, lichen planus may recur. As it heals, lichen planus often leaves a dark brown discoloration of the skin. Like the bumps themselves, these stains may eventually fade with time without treatment. When oral mucosa is affected by lichen planus, there is a slightly increased risk of developing oral cancer. If oral lichen planus is present, you should avoid the use of alcohol and tobacco products, which also increase the risk. Regular visits to the dermatologist or dentist — at least twice a year — for an oral cancer screening is recommended.
