Ingredient glossary
Ingredients
Every Lumiade formula is built from a short, purposeful list — ferments, peptides, and barrier care chosen for slow aging, not quick fixes. Here is what each ingredient does, in plain language, and where it lives in the ritual.

Radiance · Hydration
Rice Ferment
A centuries-old Korean beauty staple. Fermentation breaks rice into skin-loving amino acids and sugars that leave skin looking rested, luminous, and softly hydrated.
Found in Yun First Essence · Gyeol Rice Gel-Cream
Hydration
Hyaluronic acid
A moisture magnet that can hold many times its weight in water. It cushions skin with lightweight hydration, so fine dry lines look smoothed and makeup sits more evenly.
Found in Yun First Essence · Yun Glow Serum · Haru Barrier Cream · Gyeol Rice Gel-Cream
Tone · Texture
Niacinamide
A hard-working form of vitamin B3 loved for its gentle, everyday nature. With steady use it helps refine the look of uneven tone, enlarged-looking pores, and rough texture.
Found in Yun First Essence · Yun Glow Serum · Gyeol Peptide Ampoule · Haru Shield Sunscreen SPF 50+
Comfort
Panthenol
Pro-vitamin B5, the great soother. It helps skin feel calm and comfortable, softening the tight, dry feeling that can come with weather, actives, or simply busy weeks.
Found in Yun First Essence · Haru Barrier Cream · Gyeol Peptide Ampoule · Haru Shield Sunscreen SPF 50+
Radiance
Vitamin C derivative
A stabilized form of vitamin C, chosen for its gentleness over the pure acid. It brightens the look of dullness and helps skin appear more even and lit-from-within.
Found in Yun Glow Serum
Firmness
Peptides
Short chains of amino acids — the language skin’s own proteins are written in. In daily care they support the look of firmness, bounce, and smoother expression lines.
Found in Yun Glow Serum · Gyeol Peptide Ampoule
Barrier support
Ceramides
The mortar between skin’s own cells. Replenishing them helps skin feel resilient and comfortable, and helps hydration stay put instead of evaporating away.
Found in Haru Barrier Cream · Gyeol Rice Gel-Cream
Softening
Squalane
A weightless, plant-derived echo of skin’s own natural oils. It leaves a soft, supple, never-greasy finish that mature and combination skin both enjoy.
Found in Haru Barrier Cream
Smoothing
Adenosine
A quiet achiever in Korean age-care routines. It helps skin look smoother and more rested, softening the appearance of fine lines over time.
Found in Gyeol Peptide Ampoule
Hydration
Glycerin
One of skincare’s most trusted humectants. It draws water into the surface of the skin, keeping it feeling plump, dewy, and comfortable through the day.
Found in Gyeol Rice Gel-Cream
Calming
Centella asiatica
The “tiger grass” of K-beauty legend, treasured for its calming reputation. It helps skin under daily stress — sun, city, seasons — feel settled and comfortable.
Found in Haru Shield Sunscreen SPF 50+
