Shirok, Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Yuta Iizuka) announces the launch of a liquid foundation and pressed powder under its fermented anti-aging*1 brand "FAS" on August 26, 2026 (Wed), marking the debut of the brand's first base makeup series, "FAS The Plump Series." "FAS" is a fermented anti-aging*1 brand that elevates Japan’s traditional fermentation techniques with modern science, creating products centered on "Black Rice Ferment Filtrate*6" containing up to 738 ingredients. This autumn, commemorating the brand's third anniversary, FAS takes a new step toward becoming a comprehensive beauty brand beyond skincare, launching base makeup that achieves an unprecedented balance between multi-dimensional makeup benefits and high skincare performance. The first two products in this milestone series are the "FAS The Plump Serum Foundation," a mature skin serum foundation that delivers plump, firm-looking skin with one application, and the "FAS The Plump Pressed Powder," a moisturizing powder with an ultra-thin veil that controls shine and prevents dryness. ■ Development Background A survey conducted by "FAS" revealed that while average sleep time after nighttime skincare is about 7 hours*7, the duration from applying foundation in the morning to removing makeup is an average of 12 hours*8—significantly longer than sleep time. Additionally, feedback from loyal customers indicated that while they seek high skincare efficacy in base makeup, they often find serum foundations lacking in coverage and prone to wear-off. To address this, FAS aimed not merely to add beauty ingredients to foundation, but to create a new type of base makeup that enhances skin health while beautifully enhancing mature skin. This led to the development of both a novel cosmetic base and a new fermented-origin beauty ingredient. After two full years of planning, the brand launches this ambitious new series. ■ The Plump Series: Two Key Ingredients — Japan-First*9 "Memory Oil Gel*5" & World
