Kiyomi Skin launches 5-ALA radiance booster serum

Kiyomi Skin has introduced a new 5-ALA Radiance Booster Serum built around its highest concentration of 5-ALA yet, plus exosomes and hydrating actives. The launch targets growing demand for skin-longevity products and expands the German brand’s skincare lineup in Europe and the U.S.

Why it matters: - Kiyomi Skin is betting that consumers want more than anti-aging claims and are instead looking for skin-longevity products. - The new serum is the brand’s most advanced targeted treatment yet, with its highest concentration of 5-ALA to date. - The formula pairs 5-ALA with exosomes and hydration-focused ingredients to support radiance, barrier function and long-term skin vitality.

What happened: - Kiyomi Skin launched its 5-ALA Radiance Booster Serum on September 2, 2026. - The brand positioned the lightweight serum as a new addition to its 5-ALA-powered skincare lineup. - Kiyomi Skin said the launch reflects growing interest in cellular energy, regenerative skincare and skin longevity.

The details: - The serum centers on 5-Aminolevulinic Acid, or 5-ALA, which Kiyomi Skin uses across its top-selling formulations. - The product combines 5-ALA with next-generation exosomes. - The ingredient list includes niacinamide, sodium hyaluronate, ceramides, squalane and green tea extract. - Kiyomi Skin says the formula is designed to support hydration, barrier function and healthier-looking skin. - CEO Daniel Struve said the goal was to create a high-performance formula that combines proven 5-ALA benefits with next-generation skincare technologies. - Kiyomi Skin describes 5-ALA as an amino acid that supports skin health at a cellular level and helps promote a more radiant complexion. - The company says 5-ALA supports mitochondria’s energy production, which in turn boosts collagen and elastin production. - Kiyomi Skin cited a controlled double-blind study showing 5-ALA increased skin moisture and reduced wrinkles and wrinkle depth. - The brand was founded in 2021. - Kiyomi Skin is a German brand that markets 5-ALA products in Europe and the U.S. - The company says its broader mission is to honor the intersection of beauty and wellness.

Between the lines: - The launch follows a broader industry shift toward treatments that promise visible results and longer-term skin health. - Kiyomi Skin is using 5-ALA as a differentiator in a crowded skincare market, then layering in exosomes and familiar actives to broaden appeal. - The company is trying to bridge J-Beauty positioning with Western demand for clinical-style, ingredient-led skincare.

What's next: - Kiyomi Skin says consumers can learn more through the brand’s online boutique or Amazon. - The company also invited inquiries about speaking with formulation expert Rainer Kröpke through Trent & Company. - Kiyomi Skin is likely to use the serum launch to deepen its footprint in European and U.S. skincare channels.

The bottom line: - Kiyomi Skin’s new serum is a clear move to turn 5-ALA into a premium skin-longevity story, not just a niche ingredient claim.
