THE SCIENCE

Why Kira works.

Clinical-grade marine collagen, sourced from Japanese waters. Here's what sets us apart.

10,000mg

Clinical Dose

Every sachet delivers a full clinical dose — not the 2,000-5,000mg most brands hide behind.

93%

Absorption Rate

Hydrolyzed into small peptides for maximum bioavailability. Your body actually uses what you take.

Type I & III

Skin-Specific Collagen

The two collagen types that make up 90% of your skin. Sourced from wild-caught Japanese marine fish.

14 Days

Visible Results

Most women notice improved hydration within a week. Firmness and glow follow within two weeks.

Born from radiance. Perfected by nature.

There is a word in Japanese that has no direct translation: 輝き kagayaki. It means more than brightness or beauty. It describes that quiet, unmistakable glow that comes from within. The kind that cannot be faked, only cultivated.

KIRA was born from a deeply personal search. Our founder spent years living between Tokyo and London, watching how Japanese women approached beauty differently — not as a surface correction, but as a daily ritual of nourishment. In Japan, collagen is not a trend. It is a cornerstone — woven into meals, evening rituals, and the quiet discipline of caring for your body over a lifetime. She wanted to bring that philosophy home.

But every collagen brand she tried fell short. Doses too low to be effective. Ingredients she couldn't trace. Flavours that felt like punishment. So she went directly to the source — partnering with a marine peptide facility on the coast of Japan, where wild-caught fish collagen is cold-extracted and hydrolyzed into bioavailable peptides small enough for your body to actually absorb.

The result is KIRA: 10,000mg of clinical-grade marine collagen in every sachet. No fillers. No compromise. Just the honest, meticulous craftsmanship that Japan is known for — delivered in flavours you genuinely look forward to. Mango. Passion fruit. Or pure and unflavoured, for those who prefer simplicity.

KIRA is not about anti-ageing. It is about honouring the skin you are in — and giving it what it needs to radiate from within.

美しさは内側から輝く

Beauty radiates from within

自然の恵み

Japanese Heritage

Rooted in centuries of Japanese beauty wisdom — where radiance was never rushed, but cultivated with patience and reverence.

Clinical Precision

10,000mg of hydrolyzed marine collagen per sachet. Not a token dose — a clinically validated one, backed by peptide science.

Ocean Purity

Wild-caught from the pristine waters surrounding Japan. Sustainably sourced, cold-extracted, and traceable to origin.

REAL RESULTS

What they're saying.

Two weeks in and my makeup artist asked what I changed. It's just Kira. Every single morning.

I've tried high-end collagen brands twice the price. Nothing has worked this fast or tasted this good.

The unflavoured dissolves completely — I add it to my morning water and forget it's there. My skin doesn't forget though.

COMMON QUESTIONS

Everything you need to know.

Three things: dose, source, and bioavailability. Every sachet delivers 10,000mg of hydrolyzed marine collagen from Japan — with 93% absorption. Most competitors use 2,000-5,000mg of bovine collagen with far lower bioavailability.

Mix one sachet into 200ml of cold water, stir, and drink. Takes about 10 seconds. For best results, take every morning on an empty stomach.

Most women notice improved skin hydration within 7-10 days. Visible improvements in firmness, texture, and fine lines typically appear within 14-21 days of daily use.

Type I and Type III hydrolyzed marine collagen peptides — the two types that make up 90% of your skin. Sustainably wild-caught from Japanese waters.

Zero added sugar. Under 20 calories per sachet. The Mango and Passion Fruit flavors get their taste from natural fruit extracts — not sweeteners.

Cold water gives you the best taste and fastest dissolve. But it works great in smoothies, juice, or iced coffee too. Just avoid hot liquids — heat can reduce collagen effectiveness.
