Mature skin often needs a different approach than it did years ago — a little more hydration, a little more consistency, a little more intention. And there is one area that gets left out of this evolution more than any other: the neck and décolletage. Many of us apply a careful, multi-step routine to the face and then simply stop at the jawline, even as this area shows the same dryness, fine-line appearance, and crepey-feeling texture as the rest of mature skin. This guide walks through a simple two-step RIMAN ICD path — starting with the ICD Dermatology line and stepping up to Radiansome™100 when you are ready — and shows you how to carry that same care down to your neck and décolletage, using real products from KBeauty-USA.com.
Quick Answer: What RIMAN Routine Should Mature Skin Start With?
A simple way to begin is with the Signature RIMAN Ritual ICD Set as your foundation, then step up to the Radiansome™100 line when you want a more advanced, radiance-focused routine. Whichever path you choose, extend your moisturizer or cream down to the neck and décolletage instead of stopping at the jawline — same product, just don't stop at the jaw.
Why Mature Skin Needs a More Intentional Routine
- Mature skin may look drier or less smooth over time
- The neck may show crepey-looking texture earlier because it is often overlooked in a daily routine
- A consistent routine can support hydration, comfort, and smoother-looking skin
- Richer moisture and gentle layering can help skin feel more cared for
- Daytime sunscreen matters for the face, neck, and décolletage alike
Step One: Start with the ICD Dermatology Line
The Signature RIMAN Ritual ICD Set ($393.68) is a strong foundation for mature skin — a nine-piece routine built on RIMAN's classic Incellderm formulas, covering everything from first cleanse to final protection. Every piece is included in the set itself, and each is also available as its own product on KBeauty-USA.com:
| Included Product | Size | Product Link |
|---|---|---|
| ICD Moisture Cleansing Oil | 145ml | Shop |
| Incellderm Snow Enzyme Cleanser | 120g | Shop |
| ICD Cleansing Powder Wash | 90g | Shop |
| ICD Two Phase Oil Mist | 50ml | Shop |
| ICD Calming Balance Gel | 100ml | Shop |
| Dermatology First Package (Booster + Serum) | 130ml + 45ml | Shop |
| ICD Dermatology Cream | 50ml | Shop |
| ICD Moisture Layer Sunscreen | 50ml | Shop |
This set is a good starting point for anyone who is new to RIMAN ICD skincare, wants a complete routine rather than assembling one product at a time, and is looking to build consistency before considering a more premium routine. Every formula draws on RIMAN's heritage centella (Giant BYoungPool) and Jeju Lava Energy Water, designed to support cleansing, calming, hydration, and a smoother-looking texture — a comfortable, dependable place to begin.
Step Two: Step Up to Radiansome™100
Radiansome™100 is positioned as a premium RIMAN ICD line focused on a refined skincare experience, radiance, and mature-skin goals — a natural next step once your foundation routine feels comfortable and consistent. The line centers on three core steps:
Radiansome™100 Microfluidizer Essential Toner
A 100ml toner that opens the Radiansome™100 sequence, designed to help prep skin with a lightweight, comfortable layer of hydration before the treatment steps that follow. It is included in the RIMAN ICD Radiansome™100 Advanced Ritual Set.
Radiansome™100 Microfluidizer Ampoule
A concentrated, dropper-format treatment step — applied with one drop to each cheek and the forehead, then gently massaged in. This is the more treatment-style step of the routine, designed to support a more radiant-looking, refined complexion. Note: KBeauty-USA.com lists this product as the "Ampoule" rather than "Essence" — we are using the site's own confirmed name here for accuracy.

ICD Radiansome™100 Microfluidizer Cream
The final, sealing step of the Radiansome™100 routine, and arguably the most important one for mature skin and neck care alike — this is the step to carry generously down to the neck and décolletage, not just the face. At the time of writing, we were not able to confirm a standalone product page for this cream on KBeauty-USA.com — it is currently available as part of the RIMAN ICD Radiansome™100 Advanced Ritual Set or the Radiansome Advanced Morning Routine Set. If a standalone listing becomes available, we will update this guide with a direct link.

Based on the launch information provided, RIMAN ICD Radiansome™100 Microfluidizer Concentrate is expected soon and may become a targeted addition to the Radiansome™100 routine. Soon Available · September 1st. As with the rest of the Radiansome™100 line, we will share verified pricing, size, and ingredient details once the product is fully live on KBeauty-USA.com — we do not want to guess at specifics ahead of launch.
Why the Neck and Décolletage Should Be Part of Your Routine
Many of us apply a careful, multi-step routine to the face and then simply stop at the jawline. But the neck and décolletage can look dry, thin, or crepey-feeling too — often earlier than the face, precisely because this area gets left out of the daily routine. The fix is refreshingly simple: the same moisturizer or cream you just applied to your face can be carried gently down the neck and across the décolletage. Use upward or sweeping motions rather than tugging, and remember that daytime sunscreen belongs on the neck and décolletage just as much as the face. Same product, just don't stop at the jawline.
