Why the Dermatology First Package Is Considered the Core of RIMAN Skincare

Quick Answer: The Incellderm Dermatology First Package (Booster + Serum) is widely considered the core of RIMAN skincare because it focuses on hydration layering, barrier support, and preparing the skin for the rest of the routine. Rather than acting as a standalone treatment, it functions as a foundational step that helps improve how the skin retains moisture and absorbs subsequent products.

1. What Is the Dermatology First Package?

The Dermatology First Package is a two-product system within the Incellderm line, consisting of the Dermatology Booster EX and the Dermatology Serum EX. Unlike traditional routines where products are applied independently, these two are designed to work together in a specific sequence. If you want a step-by-step breakdown of the application, see our guide on How to Use Incellderm Booster Correctly.

2. Why Is the Dermatology First Package Considered the Core Step?

Within the broader RIMAN skincare philosophy, the First Package is often described as the “core step” for three main reasons:

• Hydration Base: It builds multiple layers of hydration, often associated with the “glass skin” appearance.
• Absorption Preparation: The Booster is used to soften and hydrate the skin surface, improving how the Serum and subsequent products are absorbed.
• Routine Consistency: It introduces a structured application method that is easy to follow morning and evening.

3. How the “Boo-Se-Boo” Method Works

A defining characteristic of the First Package is the application method commonly referred to as Booster → Serum → Booster (Boo-Se-Boo).

This layered approach differs from traditional routines where a serum is applied once. For a deeper comparison of these techniques, read our analysis on Boo-Se-Boo vs Traditional Skincare Routine.

4. Key Ingredient Approach (2026 Portfolio Context)

Based on the 2026 RIMAN product portfolio, the First Package combines botanical extracts with modern skincare technologies, including BYoungPool-3 Complex (Centella Asiatica), NMN, and Peptide Complexes.

5. What Results Are Typically Reported?

While individual experiences vary, users often report smoother skin texture, improved hydration throughout the day, and a more balanced, healthy-looking radiance.

6. How It Fits Into a Full RIMAN Routine

In the standard routine structure, the First Package is positioned between cleansing (Active Clean-Up Powder) and targeted treatments (Active Cream EX).

7. Who It May Be Suitable For

The Dermatology First Package is generally formulated to be compatible with most skin types, including sensitive and maturing skin. If you're unsure whether this specific step is necessary for your skin type, see Do You Really Need the Dermatology First Package?.

As of 2026, RIMAN has expanded across the US, Asia, and European markets like Ireland and Spain. While regional availability varies, the core routine—including the First Package—remains consistent.

9. Conclusion

Rather than functioning as a standalone product, the Dermatology First Package is positioned as a foundational step. It establishes a hydrated, balanced base that supports the effectiveness of the entire routine.
