Hyaluronic Acid Radiance Serum 30ml

Hyaluronic Acid Serum Infused in Galactomyces for 24 Hours

This hydration serum replaces purified water entirely with 100% galactomyces ferment filtrate as its aqueous base. High-molecular-weight hyaluronic acid powder is slowly dissolved into the galactomyces solution over 24 hours, creating a rich essence texture that delivers an instant surge of moisture to the skin. The oil-free formula absorbs quickly with a fresh, non-sticky finish.

Minimalist Formula Focused on Two Key Ingredients

Rather than listing dozens of actives, we concentrated on two premium ingredients.

• High-Molecular-Weight Hyaluronic Acid Powder: Attracts moisture up to hundreds of times its own weight, forming a hydrating film on the skin's surface to lock in moisture and prevent water loss
• Galactomyces Ferment Filtrate: A fermented ingredient inspired by the hands of traditional brewery artisans, it helps gently exfoliate dead skin cells and boost moisture retention for a clearer, more resilient complexion

For Dull, Dehydrated Skin

Recommended for those whose skin tone has become dull or texture rough due to dryness. Galactomyces supports skin cell turnover to restore luminosity, while hyaluronic acid floods the skin with deep, lasting hydration. A serum crafted with the care and purity of Jirisan's pristine nature, signature to Dooryuheon.

After toner, before cream — in the serum step

Apply this serum right after toning, when your skin is prepped and receptive. Formulated with galactomyces ferment filtrate and high-molecular hyaluronic acid, it delivers a dual benefit: deep hydration plus visible texture refinement. Follow with your cream to lock everything in and keep moisture levels steady throughout the day.

Morning and evening, both work beautifully

Thanks to its oil-free formula, it layers seamlessly under makeup in the morning with zero stickiness. At night, it replenishes moisture lost during the day and helps tired skin recover. With consistent daily use, you'll notice your skin texture looking smoother and more refined.

2–3 drops from the dropper, press gently to absorb

Dispense 2–3 drops into your palm and warm the serum slightly with your body heat. Smooth it evenly across your face, then press your palms gently over your skin to help it sink in faster. The texture is a rich essence, so a little goes a long way.

Pairing suggestions based on your skin concerns

• For very dry skin: Layer this serum over a deeply hydrating toner, then seal it all in with a moisture cream
• For dull, uneven texture: Use this serum consistently to take advantage of galactomyces' tone-evening benefits, and add a gentle exfoliator 1–2 times a week for best results
• For oily skin: You can skip or lighten up on cream, or use serum alone on your T-zone

Storage and usage notes

Use within 6 months of opening, and store in a cool place away from direct sunlight. Keep the dropper from touching your skin to maintain hygiene. If you experience redness or itching during use, discontinue and consult a dermatologist.
