Daily Barrier Restoration Through Rice-Derived Complexes
Sourced from Icheon—Korea’s most acclaimed rice-producing region—the Rice Core Complex is built around enzyme-treated rice bran extract and purified rice amino acids. Designed to mimic the skin’s own lipid-water balance, this system supports barrier recovery for skin fatigued by environmental stress and chronic inflammation.

All three products share a common ingredient architecture while diverging in their functional focus. The Mist Toner activates early-stage hydration and barrier priming, the Serum targets clarity and melanin equilibrium, and the Cream reinforces lamellar lipid organization to complete the skin’s recovery loop.

Texture Segmentation with Active Alignment
Three Systems, One Origin

Mist Toner (Hydration + Microbiome Repair)
A weightless dispersion designed for rapid hydration and skin priming. Includes fig, green tea, oat kernel extract, and postbiotic ferment filtrates to stabilize microflora and ease inflammation. Optimized for layering and absorption.

White Serum (Radiance + Rehydration)
A gel-type emulsion powered by niacinamide and rice amino acids. Sodium hyaluronate and glycerin form moisture channels, while a polysaccharide-stabilized structure ensures smooth delivery. Brightens uneven tone and visibly improves texture.

White Cream (Lipid Mimicry + Occlusion)
Recreates lamellar lipid film with rice-derived phytolipids, butylene glycol, and ceramides. Adds sealing protection through plant wax esters and water-binding polymers. Designed to be the final moisture-locking layer.

Ingredient Strategy: Rice Core Complex
From Royal Tribute to Functional Skincare

Rice Bran Extract (5,000ppb)
• Delivers antioxidant protection and film-forming benefits
• Contains natural phytosphingosine and trace minerals

Rice Amino Acids (100ppb)
• Enzyme-extracted to retain 8 essential amino acids
• Supports NMF activation and hydration retention

Rice-Supporting Botanical Matrix
• Centella, artichoke, fig, oat kernel, and fermented lysates
• Helps regulate inflammation and reinforce skin’s microbial barrier

RESEARCHER’S COMMENTARY
“Icheon rice is not merely a natural extract—it’s a composite matrix that integrates high-molecular, low-molecular, and fermented components into a structurally efficient delivery system. The rice amino acids and glycerin build hydration pathways, while rice bran extract forms a breathable phyto-barrier. This isn’t just moisturizing—it’s designing a self-regulating skin barrier, backed by material science.”

Icheon Rice Core Mist Toner
Daily Skin Booster in Mist Form

Overview
Designed as a mist-type skin booster, this product simplifies the daily routine by combining toner functionality with advanced hydration support. The micro-droplet spray format allows for even distribution and immediate absorption, making it suitable for both first-step hydration and layering throughout the day.

Purpose & Application
The formula is structured around a rice-based botanical complex (Oryza Sativa Bran Extract + Rice Amino Acids), acting as a core agent to restore skin’s moisture-oil balance and strengthen the barrier. The use of mist format eliminates the need for cotton pads or hand-patting, streamlining skincare without compromising efficacy.

Functional Focus & Synergistic Formulation
• Barrier repair & hydration: Ceramide NP, Polyquaternium-51, Beta-Glucan, and Sodium Hyaluronate synergistically reinforce the skin’s intercellular lipids and support moisture retention.
• Anti-inflammatory & antioxidant protection: Centella Asiatica, Green Tea (Camellia Sinensis), and Artichoke Leaf Extract reduce visible redness and oxidative stress while promoting overall skin clarity.
• Rice complex integration: The Icheon rice ingredients are enzyme-treated to enhance amino acid bioavailability. In combination with Hydrogenated Lecithin and Caprylic/Capric Triglyceride, they help emulsify micro-oils for deeper skin penetration.
• Fermented microbiome support: Lactococcus Ferment Lysate improves skin texture and contributes to long-term barrier health.
• Penetration enhancers: Hydroxypropyl Cyclodextrin and Triethylhexanoin aid delivery of active ingredients into the epidermal layer.

Results
Through a light yet functional base, the Mist Toner acts as a priming layer that hydrates, calms, and restores the skin environment. Regular use prepares the skin to better receive subsequent steps such as serums or creams, while also allowing for standalone use throughout the day to rehydrate and rebalance.

Researcher’s Commentary
The formulation emphasizes trans-epidermal efficiency without relying on heavy occlusive agents. Instead, the synergy between humectants (glycerin, propanediol), emollients (ceramides, triglycerides), and ferment-based microbiome agents offers a bioadaptive hydration model. The fine mist delivery not only supports usability but ensures a low-irritation profile ideal for reactive or sensitive skin types. The Icheon rice derivative (5,000ppb) combined with essential rice amino acids (100ppb) contributes to maintaining structural barrier lipids while stabilizing the stratum corneum under environmental stress.

Overview
A hydrogel-based eye patch combining Bakuchiol, Retinol, and low-molecular-weight peptides, designed for daily targeted anti-aging care. This product leverages hydrogel bead encapsulation technology to maximize the delivery of active ingredients while ensuring low irritation and high adherence for sensitive areas.

Purpose & Application
This patch was designed to provide dual care:
(1) Anti-wrinkle performance through Bakuchiol (10ppm), Retinol, Acetyl Hexapeptide-8, and Adenosine—ingredients known to stimulate collagen synthesis and improve dermal density.
(2) Brightening and antioxidant support from Niacinamide, Vitamin C (Ascorbic Acid), and Tocopheryl Acetate, targeting pigmentation and dull tone around the eyes.
(3) Moisture retention and barrier repair via Allantoin, Beta-glucan, Hydrogenated Lecithin, and Guar/Carrageenan/Glucomannan-based hydrogel matrix.

Results
• Clinically tested for low irritation (2023.05.12)
• Improved skin elasticity and hydration around the eye area after 2 weeks (based on internal panel study)
• Enhanced dermal penetration and user comfort by 40% compared to non-bead hydrogel patches
• Skin brightness, elasticity, and wrinkle depth all showed measurable improvements

Researcher’s Commentary
This formula applies a dual-layered anti-aging model—combining botanical retinoid (Bakuchiol) and stabilized Retinol with low-irritant carriers to ensure tolerability in the sensitive periorbital region. The hydrogel matrix, based on 8 botanical mucilages, facilitates both occlusion and transdermal penetration without disrupting the skin barrier. The inclusion of Acetyl Hexapeptide-8 complements retinoid activity by inhibiting repetitive muscle movement that leads to wrinkle formation. The formulation also avoids 9 potentially sensitizing ingredients (parabens, BHT, mineral oil, etc.), making it suitable for repeated use.

Overview
A clinically validated emulsion-type serum that volumizes hydration. Hydro Volume Lift Serum is a moisture-lifting formula designed to restore the skin’s internal water-holding capacity. By combining fermented polysaccharides, truffle extract, and multi-peptides, the serum targets visible dehydration-induced collapse in skin volume. Its lightweight milky texture spreads smoothly and absorbs quickly, leaving behind a supple and dewy finish.

Purpose & Application
Bio-fermented water retention meets peptide-firming technology
• Black Truffle Extract (Tuber Melanosporum): A rare mushroom extract rich in minerals and sugars, enhances water retention and antioxidative protection.
• Aureobasidium Pullulans Ferment: A natural biofilm former that acts as a hydration seal to reduce transepidermal water loss (TEWL).
• Hyaluronic Acid & Panthenol: Restores deep hydration and replenishes moisture reservoirs for lasting plumpness.
• Multi-functional peptide blend (e.g., Acetyl Hexapeptide-8, Octapeptide-4, Caffeoyl Tripeptide-1): Stimulates collagen, improves elasticity, and delivers firming benefits without stickiness.

Results
• Human application test (n=33, avg. age 48.4) confirmed a 0.00 irritation index
• 100% of subjects rated the serum as non-irritating
• Most common skin types among subjects: dry (55%) and combination (30%)
• Texture: light emulsion with rapid absorption, no residue

Researcher’s Commentary
Unlike conventional serums, Hydro Volume Lift is structured to convert moisture into structural skin volume. The synergy between skin-identical lipids (jojoba oil, ceramide NP), fermented polysaccharides, and low-molecular peptides creates a three-dimensional hydration framework. This design supports not only surface moisturization but also internal cohesion of the epidermis, offering a visibly denser, firmer skin appearance with every use.
