Tohtori-Irkin
Irkin Mushroom Secret
Advanced skin support inspired by fungal bioscience
The Tohtori Irkin™ collection is powered by IRPENE™, a rare bioactive complex derived from Irpex lacteus (Irkin mushroom). This medicinal fungus naturally produces protective compounds to survive in harsh environments—properties now studied for their skin-barrier, soothing, and antibacterial benefits.
Today, backed by over 10+ years of clinical study and embraced by Korean skincare professionals, its extract is carefully refined for modern skin needs. Combined with multi-layer hyaluronic acid, growth-factor care, and precisely selected actives, these formulas help replenish moisture, soften the look of fine lines, and calm acne-prone skin—supporting a smoother, clearer, and more resilient complexion over time.

What Clinical Findings Reveal
Irpene™ contains polymer components known for their role in cell-barrier protection. This means the ingredient is designed to support and maintain the skin’s natural defense structure.
With its inherent anti-inflammatory qualities, Irpene™ works like a calming touch from nature, helping your skin feel less irritated and more at ease.
Star Ingredient: IRPENE™
A high-concentration 94% IRPENE™, a bioactive complex derived from the Irkin mushroom (Irpex lacteus). This unusually high level allows the ingredient to deliver its protective properties more directly and effectively to the skin.
Combined with multi-layer hyaluronic acids and renewal-supporting actives, this concentrated formulation helps improve hydration, smoothness, and overall skin stability—making each step in the 3-product Tohtori Irkin™ collection more effective with fewer layers.
