How to use — the BooSeBoo method

1. Booster (first application): After cleansing, spray the Booster over the entire face and pat gently until absorbed. This first layer floods the skin with Giant BYoungPool™ hydration and primes it for the serum.
2. Serum: Place droplets of the Serum on your forehead and cheeks and massage gently into skin until absorbed.
3. Booster (second application): Once the serum has absorbed, spray the Booster a second time for enhanced skin hydration and to lock in the serum's active benefits — this is the "BooSeBoo" layering technique unique to the RIMAN ICD system.
4. Follow with the RIMAN ICD Dermatology Cream to seal in complete hydration.

Why we love it

At the center of the RIMAN ICD Dermatology First Package is an ingredient that no other brand can replicate: Giant BYoungPool™. This is not a standard Centella Asiatica extract — it is RIMAN's own proprietary cultivar, developed through years of research at the world's first Smart Farm dedicated to Centella on Jeju Island, and protected by 20-year Plant Variety Protection rights in both Korea and the United States. Giant BYoungPool™ features larger leaves and higher concentrations of active compounds than conventional Centella, delivering enhanced soothing, moisture, antioxidant, and skin-rejuvenating efficacy at levels that standard centella extracts cannot match. At 88% concentration in the Booster and 81% in the Serum, it is the dominant ingredient in both formulas — not a supporting player. The "BooSeBoo" application method (Booster → Serum → Booster) is not just a routine quirk: the second booster application creates a moisture-sealing layer over the serum's active delivery, compounding the hydration effect and locking the Serum's Fillerstin™, NMN, and Ergothioneine benefits in contact with the skin. Recognized with the iF DESIGN AWARD 2026, this set represents RIMAN's flagship commitment to ingredient-centered, science-driven Korean skincare. At BestSkincareUSA.com, it's the core of every RIMAN ICD routine we recommend.

Key ingredients deeper dive

• Giant BYoungPool™ Leaf Water (88% Booster / 81% Serum) — RIMAN's patented next-generation Centella Asiatica — RIMAN's exclusive cultivar of Centella Asiatica, developed at the world's first Smart Farm for Centella on Jeju Island and protected by 20-year Plant Variety Protection (PVP) rights in both Korea and the United States. Giant BYoungPool™ features larger leaves and significantly higher concentrations of the active cica compounds (madecassoside, asiaticoside, asiatic acid) than standard Centella Asiatica. At 88% and 81% concentration in the Booster and Serum respectively, it provides unmatched soothing, moisture delivery, antioxidant protection, and skin-rejuvenating benefits — forming the foundation of the entire RIMAN ICD Dermatology First Package system.
• Lava BYoungPool Water™ — Jeju volcanic energy water base — RIMAN's proprietary Jeju Lava Energy Water, ISO-certified and Halal-certified, serves as the base for both formulas. Sourced from Jeju Island's volcanic basalt natural filtration system, it delivers mineral-rich, naturally purified water that enhances the bioavailability and efficacy of every active ingredient in the RIMAN ICD Dermatology First Package.
• Fillerstin™ (Serum) — microbiome-focused anti-aging extract — A microbiome-centered active ingredient that helps reduce the appearance of aging by supporting the skin's bacterial balance. A healthy microbiome is increasingly recognized as essential to skin barrier function, resilience, and the prevention of premature aging — Fillerstin™ addresses visible signs of aging at the microbiological level, working alongside NMN for a multi-pathway anti-aging approach in the Serum.
• NMN (Nicotinamide Mononucleotide) — NAD+ precursor for fine lines, wrinkles, and hyperpigmentation — A derivative of niacinamide and the direct precursor to NAD+ (the cellular coenzyme that declines with age), NMN provides powerful antioxidant care and helps improve the appearance of fine lines, wrinkles, and hyperpigmentation. By supporting the skin's NAD+ levels, NMN helps restore the cellular energy and repair capacity that diminishes over time — making it one of the most scientifically meaningful anti-aging actives across all Korean skincare brands.
• Ergothioneine + Carnosine — premium antioxidant protection and redness reduction — Ergothioneine is considered a more powerful antioxidant than CoQ10, protecting the skin's endogenous antioxidant systems while directly reducing the appearance of discoloration and redness. Carnosine is a naturally occurring dipeptide that complements ergothioneine's activity, providing additional antioxidant and anti-glycation benefits that help keep the skin resilient and clear-looking in the RIMAN ICD Dermatology First Package Serum formula.
• Plant-based extracts and proprietary complexes — nutrients for firmness and elasticity — Various nutrients from plant-derived compounds provide broad-spectrum support for firm skin and elasticity — working alongside the Giant BYoungPool™ base and the concentrated actives to deliver the lifting, tightening, and nourishing benefits that define the RIMAN ICD Dermatology First Package's comprehensive skin-conditioning effect.

Who it's for

The RIMAN ICD Dermatology First Package is designed for all skin types — particularly those dealing with dehydration, dullness, uneven tone, fine lines, wrinkles, sagging, or loss of firmness and elasticity. It's the essential hydration and treatment core of the RIMAN ICD daily routine, making it ideal for anyone building or upgrading a Korean face routine around clinically validated, ingredient-led skincare. The BooSeBoo application method makes it especially effective for those who want a structured, results-driven hydration ritual rather than a single-step treatment. German Derma tested and validated for sensitive skin.

Pro tips and pairings

For the most effective results from the BooSeBoo method, apply the first Booster layer to skin that is still slightly damp from rinsing — the moisture helps the Giant BYoungPool™ penetrate immediately. The second Booster application after the Serum is non-negotiable: it creates the moisture-sealing layer that compounds the entire set's hydration effect and locks the Serum's actives in contact with the skin. Follow with the RIMAN ICD Dermatology Cream to seal in the complete hydration system, and finish your morning routine with the RIMAN ICD Moisture Layer Sunscreen to protect throughout the day. Together these four products — the Booster, Serum, Cream, and Sunscreen — form the complete core of the RIMAN ICD morning ritual.
