Product Advantage
Mitochondrial-Targeted Antioxidant
Ergothioneine is transported into mitochondria via OCTN1, directly scavenging ROS where cellular damage begins. It protects DNA, proteins, and lipids from oxidation more effectively than common antioxidants like glutathione.
Keywords: ergothioneine antioxidant, mitochondrial ROS scavenger
Patented Bio-Fermentation & High Purity
Our exclusive fermentation process yields 99% pure, non-GMO ergothioneine without organic solvents. It is COSMOS‑compatible, sustainable, and free from animal or plant residues.
Keywords: bio-fermented ergothioneine, high purity ergothioneine
Exceptional Thermal & pH Stability
Ergothioneine remains stable at high temperatures (up to 100°C) and across pH 2–12. It does not degrade during hot processing or long-term storage, ensuring consistent performance in creams, serums, and sunscreens.
Keywords: stable antioxidant for skincare, heat resistant antioxidant
Multi‑Functional Anti‑Aging & Brightening
Clinical studies show ergothioneine reduces UV‑induced photoaging, suppresses inflammation (IL‑6, TNF‑α), and inhibits melanin synthesis. It visibly improves skin tone, firmness, and radiance.
Keywords: anti-aging peptide, skin brightening antioxidant
Water‑Soluble & Formulation Friendly
Easily dissolved in water at low temperatures, ergothioneine integrates into any water‑based system without heating. It is non‑irritating (0% reaction in patch test) and compatible with most cosmetic ingredients.
Keywords: water soluble antioxidant, clean beauty ingredient

Product Uses
Anti‑Aging Serums
At 0.05%-5%, ergothioneine penetrates deeply to protect mitochondria from oxidative stress. It reduces fine lines, improves elasticity, and restores radiance. Ideal for daily use under moisturizer.
Brightening & Spot Correction Creams
Ergothioneine inhibits melanin synthesis and reduces UV‑induced pigmentation. At 0.02–0.1%, it visibly lightens dark spots and evens skin tone without irritation.
Sunscreens & After‑Sun Lotions
Its photostability and anti‑inflammatory action protect against UV damage. Added at 0.02–0.1%, it reduces redness, prevents photoaging, and supports DNA repair after sun exposure.
Eye Creams for Dark Circles & Puffiness
Delicate eye area benefits from ergothioneine’s ability to reduce oxidative stress and inflammation. At 0.02–0.1%, it diminishes dark circles and under‑eye puffiness.
Repair Night Creams & Sleeping Masks
Overnight, ergothioneine works at the cellular level to neutralize accumulated free radicals. It boosts collagen preservation and strengthens the skin barrier, leaving skin firmer by morning.
Soothing Gels & Post‑Procedure Care
With strong anti‑inflammatory properties, ergothioneine calms irritated skin. At 0.02–0.1%, it accelerates barrier recovery after peels or laser treatments, reducing redness and discomfort.
