The Collection
Four botanicals. One ritual.
Every stick pack delivers 10,000mg of Japanese marine collagen peptides with Vitamin C, Hyaluronic Acid, and Ceramides.
The Science
Not all collagen is created equal.
Three things separate effective collagen from everything else: source, dose, and bioavailability. We optimized all three.
Type I & III
Japanese Marine Source
Wild-caught marine collagen from Japanese waters, supplied by Nitta Gelatin. Smaller peptides mean 3x faster absorption than bovine alternatives.
10,000mg
Clinical Dose
The dose backed by research. Most brands use 2,000-5,000mg. We use the amount that clinical studies show actually moves the needle for skin, hair, and nails.
93%
Maximum Absorption
Low molecular weight (3,000 Daltons) for 93% bioavailability. Enhanced with Vitamin C for collagen synthesis and Ceramides for skin barrier support.

Our Story
Born from Japanese beauty wisdom.
KIRA means radiance in Japanese. It was born from a simple frustration: every collagen brand on the market was either underdosed, poorly sourced, or tasted terrible. Japan has been using marine collagen for over two decades — yet Western brands were ignoring everything Japanese beauty scientists had learned.
We partnered with Japanese collagen producers to source the highest-grade marine collagen peptides available — Type I & III, low molecular weight, 93% bioavailability. Then we formulated it with botanicals that honor Japanese beauty traditions: yuzu, sakura, ceremonial matcha. The result is a daily ritual that transforms your skin from within.
Radiance is not something you apply. It is something you cultivate.
