RIMAN can be confusing the first time you see the whole collection. There is a $30 cleanser. A two-product Dermatology First Package. A Starter Ritual. An Experience Kit. A complete Expert Ritual. A Radiansome Premium Set. An Advanced Ritual above that.
And the very reasonable thought is: which one am I actually supposed to buy?
Here is the short answer. You don't start by choosing the biggest set. You start by deciding two things — your main skin concern, and how much routine you will actually use. Everything else follows from that.

First — Understand the Two Main RIMAN Paths
Almost everything in the facial skincare range sits on one of two paths: Expert or Radiansome. They are not a cheap option and an expensive option. They are two different routine philosophies.
Path 1 — Expert
The Expert line is built around hydration and layered moisture, and it is where RIMAN's Boo-Se-Boo method lives. Its core is the RIMAN ICD Dermatology First Package — a Dermatology Booster and Dermatology Serum — usually finished with the RIMAN ICD Dermatology Cream.
Expert is often the more intuitive starting point if you'd describe your skin as dry, tired-looking or mature-feeling, or if you simply want to try RIMAN for the first time. It is not automatically right for everyone — if pigmentation is your main worry, the other path fits better.
Path 2 — Radiansome 100
Radiansome is the tone-focused, more premium path: radiance, and the appearance of uneven tone and dark spots. The line runs Radiansome 100 Microfluidizer Toner, Essence and Cream, with the Radiansome 100 Microfluidizer Concentrate as a targeted add-on for the eye area and neck.
Radiansome suits someone who says uneven-looking tone is their priority, or who already understands layered skincare and wants something more targeted. To be clear about what cosmetics can do: these products address the appearance of tone and dark spots. They do not cure pigmentation or treat any medical condition.
| If Your Priority Is… | Start By Exploring |
|---|---|
| Dryness and hydration | Expert |
| Mature skin plus moisture | Expert |
| A simple introduction to RIMAN | Expert |
| Boo-Se-Boo | Expert |
| Uneven-looking tone | Radiansome |
| Dark-spot appearance | Radiansome |
| A radiance-focused premium routine | Radiansome |
| Not sure yet | Experience Kit or the skin quiz |
These are guides, not rigid rules. Plenty of people have dry skin and dark spots. Pick the one that bothers you most and start there.
How Much RIMAN Do You Want?
This is the question that actually decides what you buy. There are four honest commitment levels.
Level 1 — I only want one or two products
Perfectly reasonable. You do not need a ritual.
Dry or mature-feeling skin: the RIMAN ICD Dermatology Cream ($68.38) is the richer finishing moisturiser and the simplest single entry point.
A layered treatment step: the RIMAN ICD Dermatology First Package ($102.56) is the Dermatology Booster EX (130 ml) and Dermatology Serum EX (45 ml) — the core of Boo-Se-Boo without a cleanser or cream. The cream is not included, and the product page says so plainly.
Quick hydration and glow: the RIMAN ICD Two Phase Oil Mist ($40.40) is a lightweight refresh step for a dewy-looking finish.
Lightweight hydration and comfort: the RIMAN ICD Calming Balance Gel ($40.40, 100 ml) is a leave-on gel that sits between your mist and your treatment layers. Worth saying clearly, because the names cause real confusion: this is not a cleanser. The RIMAN ICD Balancing Gel Cleanser ($30.04) is the one you rinse off.
Daily protection: the RIMAN ICD Moisture Layer Sunscreen ($37.30, 50 ml) is labelled broad spectrum SPF 50+ PA+++. Sunscreen belongs in your morning regardless of which path you choose, and it matters most for exactly the concerns people buy RIMAN for.
One catalogue note: there is no standalone Dermatology Booster or Dermatology Serum sold separately. That pair only comes inside the First Package or a set containing it.
Level 2 — I want a simple core routine
The BooSeBoo Essential Bundle ($170.94) adds the full-size Dermatology Cream (50 ml) to the First Package, giving you Boo → Se → Boo → Cream. Ideal if you already own a cleanser and a sunscreen and only want the RIMAN treatment core.
The RIMAN ICD Starter Ritual Set is also $170.94 and, as currently listed, contains the same three full-size products at the same three sizes — Booster 130 ml, Serum 45 ml, Cream 50 ml. If you are weighing them against each other, there is nothing on either page that makes one a better buy. Choose whichever listing you prefer, and don't buy both.
The RIMAN ICD Mini Ritual Set ($200.98) adds the Snow Enzyme Cleanser EX (120 g), so you get cleanser → Boo-Se-Boo → cream. Despite the name, these are full-size products — "mini" refers to the number of steps, not the bottle sizes.
| Set | What It Gives You | Best For |
|---|---|---|
| BooSeBoo Essential Bundle | Booster + Serum + Cream, full size | You already have a cleanser and SPF |
| Starter Ritual Set | The same three products, same price | Either one — not both |
| Mini Ritual Set | Cleanser + Boo-Se-Boo + Cream, all full size | A simple cleanser-to-moisturiser routine |
Level 3 — I want to try the ritual first
The RIMAN ICD Expert Ritual Experience Kit ($123.28) is a seven-piece set of mini sizes: Moisture Cleansing Oil, Balancing Gel Cleanser, Two Phase Oil Mist, Calming Balance Gel, Dermatology Booster, Dermatology Serum and Dermatology Cream. It's the genuine try-before-you-commit option, and it's the one to pick if you want to learn the textures and the sequence before spending on full sizes.
There is also a RIMAN ICD Radiansome Experience Kit at the same $123.28 — five travel sizes covering the Radiansome routine plus the cleansing duo. It is currently sold out, so check current availability rather than planning around it. If you want to start Radiansome today, the Premium Set or a single product is the route.
Experience Kits make sense if you're saying "I want to understand the textures first" or "I'm not ready for a $300–$400 ritual." They are not a universal starting point — if you already know you like the line, full sizes are better value per millilitre.
Level 4 — I want the full experience
On the Expert side, the RIMAN ICD Expert Ritual Set ($393.68) is nine full-size products: Snow Enzyme Cleanser, Moisture Cleansing Oil, Cleansing Powder Wash, Calming Balance Gel, Two Phase Oil Mist, Dermatology Booster, Dermatology Serum, Dermatology Cream and Moisture Layer Sunscreen. It's the only full ritual here that includes sunscreen.
You'll also see the RIMAN ICD Signature Ritual Set at the same $393.68. As currently listed it contains the same nine products at the same nine sizes. Treat them as one decision, not two.
On the Radiansome side, the RIMAN ICD Radiansome 100 Advanced Ritual Set ($415.44) is six full-size products: the three cleansers plus the Radiansome Toner, Essence and Cream. Note it does not include sunscreen — you'd add the Moisture Layer Sunscreen separately.
The Radiansome 100 Microfluidizer Premium Set ($310.80) is the core treatment trio only — Toner 100 ml, Essence 50 ml, Cream 50 ml — not a cleanser-to-finish ritual. If you already have cleansers you like, this is the more sensible Radiansome entry.
| Option | Best For | Routine Commitment |
|---|---|---|
| Individual product | One specific need | Lowest |
| BooSeBoo / Starter / Mini | A simple core routine | Low to moderate |
| Expert Ritual Experience Kit | Trying before committing | Moderate |
| Radiansome Premium Set | Focused Radiansome treatment | Moderate |
| Expert Ritual Set | The complete Expert system | High |
| Radiansome Advanced Ritual Set | The complete Radiansome system | High |
Choose RIMAN by Skin Concern
Dry or dehydrated-feeling skin. Focus on hydration and a proper moisturiser rather than stacking treatments. The Dermatology First Package, Dermatology Cream, Two Phase Oil Mist and Calming Balance Gel all sit here, and the Expert ritual brings them together.
Mature skin, fine lines and firmness. The same Expert core applies. Keep expectations cosmetic: these products support smoother-looking, firmer-looking, better-hydrated skin and can help with the appearance of fine lines. They do not rebuild collagen or reverse ageing, and no topical cosmetic does.
Uneven-looking tone and dark spots. This is Radiansome's lane. The Toner, Essence and Cream work on overall tone; the Concentrate is the targeted option, designed for the eye area and neck after your essence and before cream. RIMAN reports its own clinical testing on these — brand-reported studies, typically around 30 women over four weeks, which is worth knowing and worth weighing differently from independent evidence.
Dull or tired-looking skin. Dullness is usually a hydration and radiance problem, not a pigmentation one — don't treat the two as the same thing. The Two Phase Oil Mist and Dermatology First Package address the first; the Radiansome Essence the second.
Daily UV protection. The Moisture Layer Sunscreen belongs in every morning routine on either path, and especially if dark spots or visible ageing are your concern. Without it, a tone-focused routine is working against fresh sun exposure every day.
Cleansing — Which RIMAN Cleanser Do You Actually Need?
There are four, and you do not need all four.
- Moisture Cleansing Oil ($37.30) — first cleanse, for makeup and sunscreen.
- Balancing Gel Cleanser ($30.04) — daily second cleanse.
- Snow Enzyme Cleanser EX ($30.04) — the alternative daily second cleanse.
- Cleansing Powder Wash ($37.30, 90 g) — an enzyme exfoliating wash used two to three times a week, in place of your usual second cleanse. Not an every-night product.
A sensible routine is one oil cleanse when you've worn makeup or sunscreen, one daily water-based cleanse, and the powder wash a couple of nights a week instead of that second cleanse. If you want to sample the approach, the RIMAN ICD Cleansing Experience Kit ($37.30) pairs travel sizes of the oil, the gel cleanser and the powder wash.
Choose the cleansing method that fits your routine — not all of them at once.
What Is Boo-Se-Boo?
It's RIMAN's own layering method, and it's central to the Expert line:
- Boo — mist the Dermatology Booster
- Se — apply the Dermatology Serum
- Boo — mist the Dermatology Booster again
The First Package directions add a detail worth following: after the first mist, wait a few minutes to let it absorb before the serum. Then finish with cream.
Two honest caveats. Boo-Se-Boo is RIMAN's specific method — not a universal Korean skincare practice, not a dermatologist-required sequence, and not something you need to apply to other brands' products. And the booster doesn't "open pores" or push the serum deeper. It's layered hydration and treatment, which is a perfectly good reason to do it. Our full Boo-Se-Boo guide goes further.
What If You Don't Want a Long Routine?
Then don't buy one. The simplest Expert entry is the Dermatology Cream on its own, or the Dermatology First Package if you want the treatment step. The BooSeBoo Essential Bundle is the core. The Mini Ritual Set gets you cleanser to cream in four products.
And if you'd rather have everything planned for you, that's what the Expert Ritual Set and Radiansome Advanced Ritual Set are for. Just be clear about what you're buying: more products are not automatically better results. The value of a ritual set is structure, compatibility and convenience.
Expert vs. Radiansome — Quick Decision Guide
Choose Expert first if: hydration is the priority, dryness is the main concern, you want Boo-Se-Boo, you prefer the classic RIMAN ritual, or you're new to the brand.
Consider Radiansome if: uneven-looking tone is the priority, dark-spot appearance is a major concern, you want a premium tone-focused routine, or you already understand layered skincare.
Neither is a rule. If you're torn, the Experience Kit comparison covers the two side by side.
If You're Over 40, 50 or 60, Where Should You Start?
Age alone doesn't choose the product. The concern does.
- Is dryness the biggest problem? Expert — the Dermatology Cream or First Package.
- Is dullness the biggest problem? A hydration-plus-radiance approach rather than a pigmentation one.
- Are dark spots the biggest problem? Radiansome, plus daily sunscreen.
- Do you want a complete system? A full ritual set.
- Are you new to all of it? The Expert Ritual Experience Kit or a simplified set.
Mature skin does not need the most products. It needs products matched to the main concern. Our mature-skin bestsellers guide goes deeper.
Build a RIMAN Routine in Three Levels
- Simple: cleanser → one treatment → moisturiser → sunscreen.
- Layered: double cleanse as needed → hydration → Boo-Se-Boo → moisturiser → sunscreen in the morning.
- Complete ritual: use one of the current ritual sets exactly as directed.
The Master Decision Table
| If You're Saying… | Start Here |
|---|---|
| "I just want one product for dry skin." | Dermatology Cream |
| "I want the core Expert treatment." | Dermatology First Package |
| "I want Booster + Serum + Cream." | BooSeBoo Essential Bundle |
| "I want a simple cleanser-to-cream routine." | Mini Ritual Set |
| "I want to try RIMAN first." | Expert Ritual Experience Kit |
| "I want help with uneven-looking tone." | The Radiansome line |
| "I want the core Radiansome products." | Radiansome Premium Set |
| "I want the complete Expert ritual." | Expert Ritual Set |
| "I want the complete Radiansome ritual." | Radiansome Advanced Ritual Set |
| "I need daily SPF." | Moisture Layer Sunscreen |
What Not to Buy Together
The sets overlap on purpose, which makes it easy to double up by accident.
- An Experience Kit plus the matching full ritual — only if you want the minis for travel. Otherwise you're buying the same routine twice.
- The First Package plus the BooSeBoo Essential Bundle — the Bundle already contains the First Package.
- The BooSeBoo Essential Bundle plus the Starter Ritual Set — as listed, these are the same three products at the same price.
- The Expert Ritual Set plus the Signature Ritual Set — same nine products, same price.
- The Radiansome Premium Set plus individual Toner, Essence and Cream — unless you're deliberately restocking one of them.

Radiansome-curious? Start with a single product or the Premium Set, then step up to the Advanced Ritual Set if you want the cleansers included too.

Frequently Asked Questions
What is RIMAN skincare?
RIMAN is a Korean skincare brand whose ICD (Incellderm) range covers cleansers, boosters, serums, moisturisers, sunscreen and targeted treatments, organised mainly into the Expert and Radiansome 100 lines.
Where should I start with RIMAN?
With two questions: what's your main skin concern, and how much routine will you actually use? Dryness points to Expert, uneven-looking tone to Radiansome. Then pick a commitment level from one product up to a full ritual.
What's the difference between Expert and Radiansome?
Expert is hydration and layered moisture, built around Boo-Se-Boo. Radiansome is tone-focused and more premium, built around the Microfluidizer toner, essence and cream. They're different philosophies, not just different price points.
Which RIMAN products are good for dry skin?
The Dermatology Cream as a finishing moisturiser, the Dermatology First Package for the treatment step, and the Two Phase Oil Mist or Calming Balance Gel for lighter hydration.
Which RIMAN products are best for mature skin?
It depends on the concern rather than the age. Dryness points to the Expert core; dark spots to Radiansome; dullness to hydration plus radiance. Matching the product to the concern matters more than buying more products.
Which RIMAN products target uneven-looking tone?
The Radiansome 100 line — Toner, Essence and Cream for overall tone, and the Concentrate for targeted use on the eye area and neck.
What is Boo-Se-Boo?
RIMAN's layering method: Booster, then Serum, then Booster again, finished with cream. It's specific to RIMAN rather than a universal Korean skincare rule.
What's the difference between the First Package and the BooSeBoo Bundle?
The First Package is the Booster and Serum only. The BooSeBoo Essential Bundle is that same pair plus the full-size Dermatology Cream.
Should I start with an Experience Kit?
Only if you want to test textures and the routine before committing. If you already know the line suits you, full sizes are better value. The Expert Ritual Experience Kit is in stock; the Radiansome version is currently sold out.
Which RIMAN ritual set is best for beginners?
The Mini Ritual Set if you want cleanser to cream in four full-size products, or the BooSeBoo Essential Bundle if you already own a cleanser and sunscreen.
Do I need the full RIMAN ritual?
No. A ritual set buys you structure and convenience, not better results by virtue of quantity. A cleanser, one treatment, a moisturiser and sunscreen is a complete routine.
Does RIMAN have a sunscreen?
Yes — the Moisture Layer Sunscreen, labelled broad spectrum SPF 50+ PA+++. It's included in the Expert Ritual Set but not in the Radiansome Advanced Ritual Set, so check before assuming.
Can I mix RIMAN with other skincare brands?
Yes. Nothing requires a single-brand routine. Introduce one new product at a time so you can tell what's working, and follow each product's own directions for order of use.
Is KBeauty-USA the official RIMAN corporate website?
No. KBeauty-USA.com is an independent RIMAN Planner website, not RIMAN corporate. We sell authentic RIMAN products as an authorised independent Planner.
