Definitions

  • One aspect of the invention relates to a topical composition, comprising at least one ergothioneine, an analog or derivative thereof, or a dermatologically acceptable salt thereof, for preventing or treating skin aging, particularly, premature aging.
  • Another aspect of the invention relates to a method for treating skin aging, comprising topical application of the composition of the invention. This topical composition has been reported to rarely produce skin irritation.
  • Skin is the main barrier that segregate our body from the outer environment and protects us against environmental stressors. However, like other human organs, skin is also subject to the aging process. Skin aging is a complex biological phenomenon, influenced by both intrinsic factors (e.g., genetics, cellular metabolism, hormone environment) and extrinsic factors (e.g., chemicals, toxins, pollutants, ultraviolet (UV) , and ionizing radiation) , and affecting different constituents of the skin.
  • intrinsic factors e.g., genetics, cellular metabolism, hormone environment
  • extrinsic factors e.g., chemicals, toxins, pollutants, ultraviolet (UV) , and ionizing radiation
  • Intrinsic aging is an inevitable, genetically determined process that affects unexposed and exposed skin and is characterized by dryness, laxity, fine wrinkles, and skin atrophy, while extrinsic aging is engendered by external environment factors such as air pollution, smoking, poor nutrition, and sun exposure, resulting in coarse wrinkles, loss of elasticity, laxity, and rough ⁇ textured appearance (Cell Transplant. 2018 May; 27 (5) : 729–738) . While many external factors could contribute to skin aging, ultraviolet (UV) radiation from sunlight is the primary factor of extrinsic skin aging, also referred to as premature skin aging or photoaging. UV irradiation can induce non ⁇ genomic signal transduction.
  • UV ultraviolet
  • ROS reactive oxygen species
  • Photoaging can be controlled to an extent as it is a result of external factors. Photoaging affects the sun ⁇ exposed areas and is characterized clinically by fine and coarse wrinkling, roughness, dryness, laxity, and pigmentary changes. There is also an increase in development of benign and malignant neoplasms on photoaged skin (Journal of the American Academy of Dermatology, Volume 49, Issue 4, October 2003, Pages 690 ⁇ 697) . The anti ⁇ aging strategies to combat skin aging signs and dysfunction have been developed over the last decades. As people’s cosmetic requirements increase, more research efforts are conducted to help relieving skin aging or preventing of extrinsic aging from occurring.
  • Ergothioneine is a naturally occurring, sulfur ⁇ containing amino acid, and is presumed to function as a natural antioxidant. It is mainly found in mushrooms, but also in king crab, and animals that have grazed on grasses containing ergothioneine. Since humans or other vertebrates are unable to synthesize ergothioneine, it can only be acquired by diet. Studies in animals and humans have found no toxicity or adverse effects to be associated with ergothioneine administration, even at high doses. Recently, ergothioneine (Tetrahedron, Paris, France) has attained European Food Safety Authority approval as a Novel Food in the European Union and is generally recognized as a safe supplement and food ingredient by the Food and Drug Administration in the US (GRAS notice No. 734) (FEBS Letters 592 (2016) 3357–3366) .
  • Applicants of the present invention have investigated the safety and efficacy of a composition comprising ergothioneine on alleviating skin aging, and provided a topical composition comprising at least one ergothioneine, an analog or derivative thereof, or a dermatologically acceptable salt thereof, which can counteract or delay skin aging signs in a safe and effective way.
