The Challenge

Tired of serums that promise hydration but leave your skin thirsty?

Most hyaluronic acid serums use only one molecular weight — large molecules that sit on the skin's surface without truly penetrating. The result: temporary softness that disappears within hours.

Your skin has multiple layers, each requiring different-sized molecules to absorb hydration effectively. Single-weight HA can never reach the deeper dermis — where lasting moisture really lives.

The Science

From Surface to Deep Layers:
Complete Hydration

Spring Subun Ampoule combines 5 molecular weights of hyaluronic acid in one formula — each precisely calibrated to target a different depth of your skin.

Ultra-Low MW HA Nano

Penetrates the deepest dermal layer to boost long-term collagen synthesis and structural hydration. ~5 kDa.

Low MW Hydrolyzed HA Deep

Reaches the epidermis-dermis junction, plumping fine lines from within. 50–150 kDa.

Medium MW HA Mid

Works in the living epidermis to retain moisture and strengthen the skin barrier. 300–500 kDa.

High MW HA Upper

Creates a flexible moisture-film in the stratum corneum for all-day softness. 800 kDa–1 MDa.

Acetyl Glucosamine HA Surface

Seals the skin surface with an instant dewy glow and locks all hydration in. >1 MDa.

Frequently Asked Questions

Where can I buy BIOCESS Spring Subun Ampoule?

Spring Subun Ampoule is now available on Amazon US. You can purchase directly at amazon.com/dp/B0H327LYWT. Orders are eligible for Amazon Prime fast shipping.

What makes 5 types of hyaluronic acid better than one?

Single-weight hyaluronic acid can only reach one layer of skin. Our 5-molecular-weight system works simultaneously at every depth — from the deepest dermis to the outermost surface — creating truly comprehensive, lasting hydration that single-weight products simply cannot achieve. Think of it like watering not just the top of the soil, but all the way to the roots.

Is Spring Subun Ampoule suitable for sensitive skin?

Yes. The formula is designed to be gentle and non-irritating. It is free from parabens, artificial colorants, and known irritants. The inclusion of allantoin and centella asiatica further helps calm sensitive or reactive skin. As with any new product, we recommend a patch test before full application.

How much product is in one bottle? How long does it last?

Each bottle contains 80ml (2.7 fl. oz.) — significantly more than the industry standard 30ml serums. With recommended twice-daily use (3–4 drops per application), one bottle lasts approximately 2–3 months, making it exceptional value compared to similarly priced serums.

How do I incorporate it into my routine?

Apply 3–4 drops onto cleansed, slightly damp skin before your moisturizer. Use morning and evening for best results. The slightly damp skin technique is key — hyaluronic acid works by binding to water, so having moisture present helps it absorb and perform optimally. Learn more on our Product page.

Is this product from Korea? What is K-Beauty?

Yes — BIOCESS is a Korean beauty brand based in Seoul, South Korea. K-Beauty (Korean Beauty) is globally recognized for its science-driven approach to skincare, innovative formulations, and multi-step hydration philosophy. South Korea invests significantly more in cosmetic R&D than global averages, resulting in breakthrough ingredients and technologies like our 5-layer HA system. Learn more on our Science page.
