No.1 Pantothenic B5 Active Soothing Serum

Pantothenic Acid meets Hyaluronic Acid in a 7-Second Hydration & Soothing Serum

A hydration and soothing serum designed for skin prone to excess sebum and breakouts. Micro pantothenic acid absorbs deep into the skin, while 4 types of hyaluronic acid deliver moisture to every layer. The lightweight, fresh texture absorbs quickly without any greasy residue, keeping skin hydrated for hours. Beta-glucan helps strengthen the compromised skin barrier, and 4% niacinamide targets post-breakout marks.

Soothing Efficacy Confirmed by Clinical Testing

A clinical study conducted after 4 weeks of use showed meaningful results.

• 62.22% improvement in newly formed 1mm breakouts
• 37.41% improvement in skin oil levels
• 23.72% improvement in visible sebum in pores

User satisfaction surveys also recorded over 99.9% for hydrating feel, fast absorption, and soothing effect on sensitive skin.

Recommended for Oily, Breakout-Prone Skin

12 soothing booster ingredients work in synergy to help control sebum and calm the skin. Nature-derived soothing ingredients such as Houttuynia Cordata Root Extract, Centella Asiatica Leaf Extract, and Green Tea Extract, along with Dipotassium Glycyrrhizate and Beta-Sitosterol, gently comfort skin sensitized by external stressors. Especially suitable for combination skin that's oily on the surface but dry underneath, and oily skin troubled by frequent breakouts.

Use after toner, before cream

This is a serum you apply after cleansing and toning, but before your moisturizer. After prepping your skin with a Step 1 toner or pad, layer this serum on top so the pantothenic acid and hyaluronic acid can absorb more effectively. Finish with a cream to complete your hydrating, soothing routine.

Suitable for morning and evening use

Thanks to its lightweight, water-based texture, it won't interfere with makeup in the morning, and in the evening it helps calm skin stressed by the day. If your skin tends to be oily or breakout-prone, use it consistently every day.

Apply 2–3 drops and gently spread across the face

Dispense 2–3 drops with the dropper and dot them onto both cheeks, forehead, and chin, then gently spread with your fingertips. The formula absorbs in just 7 seconds, so there's no need to pat or rub—it sinks in on its own. For targeted care, feel free to apply an extra layer directly onto breakout areas.

Recommended combinations by skin concern

• Excess oil & breakouts: Pair Step 1 toner → this serum → Step 1 cream for a full-line routine that delivers up to 1958% synergy
• Dehydrated skin: With four types of hyaluronic acid, layering it under a rich moisturizer helps relieve that tight, parched feeling
• Dark spots & marks: The 4% niacinamide content also contributes to a more even-toned complexion

Storage and usage tips

Store in a cool place away from direct sunlight, and avoid letting the dropper touch your skin directly. If redness or irritation occurs during use, discontinue and consult a dermatologist.
