About

This trial employed a non-randomized, double-blind, placebo-controlled design to evaluate the effects of DR. ERGO® Capsules (each containing 30mg of ergothioneine) on the skin condition of women aged 35 to 59 after continuous daily intake for 8 weeks. The trial assessed skin condition across multiple dimensions, including brightness, color tone, melanin, erythema, gloss, elasticity, and spots, using various instruments and questionnaire surveys. Additionally, safety was monitored through daily log records and safety evaluations.

Full description

Ergothioneine (EGT), a naturally occurring amino acid-like antioxidant, was first discovered in Clavieps purpurea in 1909. It is widely found in mushrooms, legumes, and certain animal tissues. Studies have shown that ergothioneine protects skin cells by scavenging free radicals and reducing oxidative stress, thereby delaying skin aging. Additionally, it can inhibit melanin production, improve uneven skin tone, enhance the skin barrier function, and boost skin elasticity and radiance. In recent years, with growing attention to nutricosmetics, ergothioneine has gained significant interest for its potential anti-aging and skin-enhancing benefits.

The trial employed a non-randomized, double-blind, placebo-controlled design, adhering to the principles of the Helsinki Declaration and relevant Japanese ethical guidelines, and received approval from an ethics review committee. The primary objective of the study was to evaluate the effects of daily consumption of one DR. ERGO® capsule (each containing 30mg of ergothioneine) on the skin condition of women aged 35 to 59 over an 8-week period.

The trial design included strict inclusion and exclusion criteria to ensure consistency in the health status and testing conditions of the participants. During the trial, participants were required to maintain their normal lifestyle habits and avoid using any medications or cosmetics that might affect their skin condition. The study assessed skin condition across multiple dimensions-including brightness, color tone, melanin levels, erythema, gloss, elasticity, spots, and wrinkles-using various instruments and questionnaires. Additionally, safety was monitored through diary logs and safety assessments.
