L Ergothioneine Skin Care

Ergothioneine, pronounced as er-go-thigh-o-neen, is an amino acid with antioxidant properties that is naturally present in the body. It is particularly abundant in cells that are susceptible to damage from free radicals, and L ergothioneine skin care play a role in safeguarding their mitochondria, which are involved in energy production. Since our bodies are unable to produce ergothioneine, it must be obtained through dietary sources. Fortunately, mushrooms are among the most plentiful natural sources of ergothioneine, so mushroom enthusiasts are in luck.

 

Although there is limited research on the use of ergothioneine in skincare, studies have indicated that L ergothioneine skin care has the potential to not only prevent oxidative damage but also assist in DNA repair in cells that have been exposed to UV light. In a comparative study with idebenone (Coenzyme Q10), ergothioneine demonstrated faster and more effective antioxidant activity in safeguarding against reactive oxygen species (ROS) following UVA ray exposure.

 

 

Antioxidant Properties of L-Ergothioneine

Under normal circumstances, free radicals are essential within the body. However, excessive free radicals can disrupt the body's physiological functions, leading to oxidative stress. This results in an imbalance where the repair system is unable to efficiently clear the excess free radicals. The manifestation of this imbalance can lead to various diseases, while on the skin, it may cause aging symptoms such as dullness, fine lines, and sagging. Therefore, in specific situations, it is necessary to supplement the body with exogenous antioxidants to assist in the removal of excess free radicals.

 

L-ergothioneine, as a rare natural chiral amino acid, is an important physiological active substance in the body. Its antioxidant properties can be observed in six main aspects:

 

■ Elimination of reactive oxygen species

■ Elimination of reactive nitrogen species

■ Activation of antioxidant enzymes and inhibition of superoxide dismutase

■ Chelation of divalent metal ions

■ Ultraviolet light filtering

■ Cellular physiological protectant

 

Applications of L ergothioneine skin care

L-Ergothioneine has shown promising applications in various fields, including cosmetics, functional foods, pharmaceuticals, therapeutics, and biomedical research.

 

Cosmetics: It can be used in skincare products for radiation protection, skin whitening, wrinkle reduction, and anti-aging effects. Companies such as Estée Lauder, Shin-care, OXIS, and others have introduced products containing L-ergothioneine to the market.

 

Food industry: L-Ergothioneine can be used as a food additive, food preservative, dietary supplement, and health food ingredient. Products containing pure L-ergothioneine have received certification from the U.S. FDA.

 

Pharmaceuticals and therapeutics: L-Ergothioneine has potential applications in the treatment of cataracts and as an organ preservation agent.

 

Please note that the information provided here reflects the potential applications of L-ergothioneine up until my last knowledge update in September 2021. There may have been further advancements or developments in its applications since then.

 

 

Key Benefits of L-Ergothioneine in Cosmetics:

Skin Whitening:

L-Ergothioneine, being a natural antioxidant, offers high cellular protection without toxicity and is resistant to oxidation in water. This allows its concentration in certain tissues to reach up to 7 mmol/L and stimulate the body's natural antioxidant defense system. Research has shown that adding L-Ergothioneine to cosmetics at concentrations of 0.01% to 0.03% can inhibit pigment formation and deposition, leading to skin whitening.

 

Anti-Aging:

L-Ergothioneine is highly effective in antioxidant activity, which helps delay the aging process. L'Oréal has applied for a patent titled "Use of ergothioneine and/or its derivatives as an anti-glycation agent," suggesting that L-Ergothioneine and its derivatives have the ability to reduce or even prevent protein glycation. This helps prevent age-related loss of skin elasticity, modify and improve facial contours, and prevent or improve the appearance of cellulite.

 

Sun Protection:

L-Ergothioneine has an absorption wavelength similar to DNA within the ultraviolet absorption range. With a molar extinction coefficient of 1.4 * 104 M-1 cm-1 and a λmax of 257, it can minimize the formation of reactive oxygen species and protect cells from radiation damage. Therefore, L-Ergothioneine can serve as a physiological filter for UV rays. Multiple studies have demonstrated that L-Ergothioneine can prevent skin damage caused by UV radiation, making it an effective sunscreen ingredient.

 

Anti-Inflammatory and Anti-Acne:

Inflammation is the body's response to skin infections, and excessive UV exposure and stress are triggers for skin inflammation. Studies have shown that L-Ergothioneine has anti-inflammatory effects in skin cells, and when used in combination with vitamin C, it produces more significant results. Elizabeth Arden conducted experiments on the reparative effects of L-Ergothioneine on UV-induced skin inflammation, demonstrating its ability to alleviate UV-induced skin inflammation and photodamage.

 

Synergistic Effects:

L ergothioneine skin care can regulate intracellular redox reactions and participate in cellular energy regulation. It acts as a physiological protectant, with well-established biological and pharmacological characteristics, ensuring safety and stability. Therefore, incorporating L-Ergothioneine into a product not only helps maintain the stability of other ingredients but also promotes the absorption of active ingredients by cells. It exhibits excellent synergistic effects, enhancing the efficacy of other ingredients and achieving a 1+1>2 effect. For example, using L-Ergothioneine in an antioxidant product not only provides potent antioxidant activity itself but also synergizes with other antioxidants, enhancing their effectiveness.
