Summary
Comparing 3 Japanese first-step serums designed to prepare skin after cleansing. My #1 pick is matsukiyo Booster Serum (absorption enhancement), #2 is SOFINA iP Base Care Serum (skin activation), and #3 is matsukiyo Vitamin C Mist (convenient antioxidant care). Each serves different purposes to condition skin and enhance the effectiveness of subsequent skincare products.
Introduction
Have you ever applied toner or serum after cleansing, only to feel like it’s just sitting on your skin’s surface? This frustration is particularly common in Southeast Asia’s humid environment, where skincare products often struggle to penetrate effectively.
Japanese skincare introduces the concept of “first-step serums” – products used immediately after cleansing to prepare skin for optimal absorption of subsequent treatments. This category represents Japan’s meticulous approach to skincare layering, rarely seen in Western beauty routines.
As a beauty enthusiast, I became interested in this category when I felt my regular skincare routine could be more effective. Today, I’ll compare 3 popular Japanese products, each with distinct characteristics and purposes.
What Are First-Step Serums?
Basic Functions
First-step serums prepare freshly cleansed skin to become more “receptive” to subsequent products. Specifically, they:
- Enhance Absorption: Improve skin’s moisture pathways to help products penetrate better
- Condition Skin: Soften tired or hardened skin texture
- Provide Base Nutrition: Supply foundational ingredients that support further treatments
Importance in Southeast Asian Climates
In hot, humid environments, moisture can accumulate on the skin surface, making skincare products harder to absorb. Additionally, factors like air conditioning, temperature fluctuations, and air pollution can destabilize skin condition. In such environments, the “preparation” step becomes particularly crucial.
Quick Comparison Table

| #1 | matsukiyo Booster Serum | Absorption enhancement | Niacinamide, Ceramides | ★★★★★ | Immediately after cleansing |
| #2 | SOFINA iP Base Care Serum | Skin activation | Carbonated foam, Korean Ginseng | ★★★★☆ | Morning/tired skin |
| #3 | matsukiyo Vitamin C Mist | Antioxidant protection | Vitamin C, Niacinamide | ★★★☆☆ | Anytime for convenience |
Product Reviews
#1: matsukiyo Booster Serum
Why #1? Focuses on the fundamental function of absorption enhancement and works for various skin types.
Product Features
This matsukiyo private brand product features a simple formulation with niacinamide and ceramides. Niacinamide is known for supporting skin barrier function and addressing pore appearance, while ceramides are essential for moisture retention, especially in dry environments.
The combination of these two ingredients helps establish basic skin condition while supporting the penetration of subsequent products.
Texture & Feel
Water-like, lightweight texture that absorbs quickly into skin. No stickiness, allowing smooth layering of following toners and serums without heaviness. Fragrance-free and colorant-free formulation suitable for sensitive skin.
User Reviews
Common feedback includes “toner penetrates better” and “skin feels softer.” Some note “effects are subtle” or “no immediate results.” Most users notice benefits with consistent use.
My Assessment
A straightforward product that concentrates on the core function of “absorption enhancement” that defines first-step serums. Affordable pricing makes it accessible for first-time users in this category.

#2: SOFINA iP Base Care Serum
Why #2? Unique carbonated foam technology provides a special experience for activating tired skin.
Product Features
This Kao SOFINA iP product dispenses as carbonated foam, creating a unique serum experience. The carbonation stimulates circulation to energize skin, while Korean ginseng extract incorporates traditional skin-activating ingredients.
Texture & Feel
Pumps out as mousse-like foam with a tingling carbonation sensation when applied. As you massage it in, the foam disappears and skin feels slightly warm. The stimulation helps wake up sluggish skin.
User Reviews
Users appreciate “skin feels awakened in the morning” and “improves complexion.” Some find it “too stimulating” or “dislike carbonation.” Results vary by individual, with tired skin showing the most dramatic improvement.
My Assessment
The unique carbonated foam technology is interesting and particularly effective for morning skin activation. However, since it doesn’t suit everyone, it ranks second.

#3: matsukiyo Vitamin C Mist
Why #3? Convenience is appealing, but it lacks the specialized focus of the other two products as a first-step serum.
Product Features
Large 200ml mist format containing vitamin C and niacinamide. Features antioxidant vitamin C to protect skin from environmental stress while offering convenient application.
Texture & Feel
Fine mist covers entire face with wide coverage. Watery texture absorbs immediately into skin. Light enough to use over makeup for midday touch-ups.
User Reviews
Users praise “easy to continue using” and “helpful for midday dryness.” Some note “mild effects” or “mist too fine.” Convenience factor receives high marks.
My Assessment
Convenience and large volume are attractive for daily use. However, it lacks the specialized focus of the other two products as a first-step serum, placing it third.
Real Voices
26-year-old, combination skin: “Since starting matsukiyo Booster Serum, my usual toner absorbs much better. I especially notice improvement in dry areas.”
32-year-old, easily fatigued skin: “SOFINA iP carbonated foam has become my morning ritual. The tingling sensation wakes me up and improves my complexion.”
