Every great Korean skincare ritual has a heart — the step where hydration stops being a chore and starts becoming a glow. In the Incellderm world, that heart is the RIMAN ICD Dermatology First Package: the iconic Dermatology Booster EX and Dermatology Serum EX, sold together as the duo behind RIMAN's famous "Boo-Se-Boo" layering technique. At $102.56 (with pay-in-4 available at about $25.64), it is the most-loved way to bring the Expert ritual's signature steps home.
In this guide, we unpack exactly what is in the package, how the Boo-Se-Boo method works, which skin goals it supports, and how to build a complete morning and evening routine around it.
What Is the RIMAN ICD Dermatology First Package?
The Dermatology First Package pairs two full-size Expert-line essentials that are designed to work in tandem:
- ICD Dermatology Booster EX (130ml / 4.39 fl. oz.) — a moisturizing booster mist that delicately layers hydration for a dewy, healthy-looking complexion.
- ICD Dermatology Serum EX (45ml / 1.52 fl. oz.) — a hydrating glow serum that helps skin look luminous, smooth, and radiant.
Both formulas are built on a remarkable base: BYoungPool (Centella Asiatica) leaf water makes up 88% of the Booster and 81% of the Serum — the soothing, moisture-loving botanical K-beauty devotees know and trust — joined by NMN (a niacinamide derivative that helps soften the look of fine lines and uneven-looking tone), hyaluronic acid, ceramide NP, panthenol, and peptide and berry-extract complexes. The line is German derma-tested, made with all-natural ingredients, cruelty free, and sustainably made.
And the results speak in numbers: in testing shown on the product page, conducted by the P&K Dermatology Clinical Research Center (39 adult women aged 33–65), the duo showed a 99.7% improvement in skin radiance.
Curious already? You can shop the RIMAN ICD Dermatology First Package any time — but first, let us show you how it works.
What's Included in the RIMAN ICD Dermatology First Package
| Included Product | Product Type | Routine Step | What It Helps With | How to Use |
|---|---|---|---|---|
| ICD Dermatology Booster EX (130ml) | Moisturizing booster mist | Steps 5 & 7 of the Expert ritual (used twice) | Layers immediate and lasting-feeling hydration; helps skin look dewy, healthy, and prepped so the serum absorbs beautifully | Spray onto the face and wait a few moments to absorb — once before the serum, and once more after |
| ICD Dermatology Serum EX (45ml) | Hydrating glow serum | Step 6 of the Expert ritual | Helps boost the look of radiance, supports an even-, smoother-looking tone, and helps soften the look of fine lines | Place droplets on the forehead and cheeks, then massage gently into skin between your two booster layers |
Note from the product page: the ritual finishes with the ICD Dermatology Cream, which is not included in this package — see the pairing suggestion below.
The Boo-Se-Boo Technique: Why This Duo Is Used in Three Steps
"Boo-Se-Boo" is RIMAN's signature layering method — Booster, Serum, Booster:
- Booster first: a fine mist preps skin and opens the door for what follows.
- Serum second: the glow treatment goes on while skin is optimally receptive.
- Booster again: a second mist helps seal the serum in for enhanced-feeling hydration.
It takes less than a minute, and it is the difference between putting on products and performing a ritual. K-beauty has always known that how you layer matters as much as what you layer — Boo-Se-Boo simply makes the right order effortless.
How to Use the RIMAN ICD Dermatology First Package
Morning Routine
After cleansing and your usual toner or balancing step, spray the Dermatology Booster EX and let it absorb for a few moments. Massage in droplets of the Dermatology Serum EX, then mist the Booster once more. Follow with your moisturizer — and your skin walks out the door looking dewy and rested.
Evening Routine
After your evening cleanse, repeat the same Boo-Se-Boo sequence: booster, serum, booster. Finish with the ICD Dermatology Cream (sold separately) massaged in as your final sealing step — the pairing the ritual was designed around.
Beginner Tip
Patience is the secret ingredient: give the first booster layer a few moments to absorb before applying the serum. Rushing the layers is the most common reason routines underdeliver — the ritual rewards the pause.
Daytime Sunscreen Reminder
Always finish your morning routine with a broad-spectrum SPF as the true last step. The hydrating ICD Moisture Layer Sunscreen (SPF 50+) layers beautifully over the Boo-Se-Boo steps and keeps your glow protected.
Who Is This Package Best For?
Customers Trying RIMAN ICD Skincare for the First Time
The Booster and Serum are the products Incellderm fans talk about most — starting here means starting with the line's heart, in full sizes, at the friendliest price of the Expert sets.
Customers Wanting the Core of a Korean Skincare Routine
This duo covers the treat-and-boost center of the ritual (steps 5–7). Add your own cleanser and cream — or grow into a complete set later — and the routine builds itself around this anchor.
Customers Looking for Glowing-Looking Skin
Radiance is this package's signature: a hydrating glow serum wrapped in two layers of booster mist, with a 99.7% skin-radiance improvement result shown on the product page.
Customers with Dry-Feeling or Dull-Looking Skin
With centella leaf water as the very base of both formulas plus hyaluronic acid, panthenol, and ceramide NP, the duo delivers immediate and lasting-feeling hydration that helps tired-looking skin appear plump and luminous.

Why the Dermatology First Package Works Well as a Skincare Ritual
- It keeps you consistent. A set you enjoy using twice a day is a ritual you actually keep — and consistency is where visible results live.
- The correct order is built in. Booster, serum, booster: the sequence is the product. There is no wondering what goes first.
- No pairing guesswork. Both formulas share the same centella-first philosophy and are designed to layer together without pilling or conflict.
- It builds toward a complete routine. The duo slots directly into the Expert ritual after your Calming Balance Gel step and hands off perfectly to the Dermatology Cream — so your routine can grow one piece at a time.
- You experience the line as intended. Skincare systems are formulated as systems; using the Booster and Serum together lets you feel what Incellderm designed, not a mix-and-match approximation.
