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.
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.

Purpose
BASIC_SCIENCE

Brightness & Color
Using the SPECTRO PHOTOMETER NF555 (Japan Electric Color Industry Co., Ltd.), measure the brightness and color at the intersection points of vertical lines below both outer canthi and horizontal lines from the alae nasi. The L\*a\*b\* method is used to measure L\* value (brightness), a\* value, and b\* value (color). Higher values indicate brighter or more intense colors.
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.
Melanin
Using the Mexameter® MX 18 (Courage+Khazaka electronic GmbH), measure melanin at the same facial points as above to assess the content of melanin.
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.
Erythema
Using the Mexameter® MX 18 (Courage+Khazaka electronic GmbH), measure erythema at the same facial points as above to assess the content of erythema.
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.
Gloss (Shine)
Using the Glossymeter GL200MP (Courage+Khazaka electronic GmbH), measure the gloss at the specified facial points. This device measures true gloss unaffected by skin surface texture or color.
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.
Elasticity
Using the Cutometer® MPA580 (Courage+Khazaka electronic GmbH), measure elasticity at the designated facial points. Skin elasticity is evaluated through R2 (total elasticity), R5 (net elasticity), and R7 (elasticity upon retraction) ratios.
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.
Spots
Using VISIA® Evolution (Canfield Scientific Inc.), measure spots on both sides of the face at the defined locations. Assess the number of spots.
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.

Skin Condition
Conduct three surveys before the trial begins, and at 4 and 8 weeks into the trial, covering 11 items: "moisture," "dryness," "softness," "gloss," "smoothness," "skin allergy condition," "texture," "makeup adherence," "tightness," "wrinkles," "transparency," "tightness after washing," "brightness," and overall skin satisfaction. Participants rate these aspects on a 9-point scale ranging from "very poor" to "very good."
Time frame: Before the trial begins, at 4 weeks, and at 8 weeks.
