VT Cosmetics S4 MOISTURE AMPOULE

The S4 Moisture Ampoule is a hydration- and barrier-focused ampoule from VT Cosmetics, built around niacinamide and panthenol as its primary actives, supported by ceramide NP, centella asiatica extract, and squalane. VT markets it as a customizable, daily-use step from its Cica Exosome Solution concept, intended to intensively soothe and moisturize sensitive or compromised skin.

Key Benefits

• Hydrates and helps strengthen the look of the skin barrier
• Soothes sensitive or stressed skin
• Supports smoother, calmer-looking skin texture with daily use
• Lightweight enough for layering under other treatments or moisturizer

When to Use

• Morning and/or evening, as a hydrating step after cleansing and toning, before heavier creams
• Suitable for daily use, including on sensitive or barrier-compromised skin
• Can be used alongside (not necessarily in place of) other Reedle Shot ampoules, positioned by VT as a hydration-support step

How to Use

• Apply an appropriate amount to cleansed skin
• Gently massage along the skin's texture until absorbed
• Follow with moisturizer to seal in hydration

Key Ingredients

• Niacinamide: Multitasking Vitamin B3 that supports barrier function and skin tone
• Panthenol (Pro-Vitamin B5): Hydrating and soothing humectant
• Ceramide NP: Helps lock in moisture and support the skin's barrier
• Centella Asiatica Extract: Calming botanical extract used to support skin repair
• Squalane: Lightweight emollient that helps reinforce the moisture barrier

Precautions

• Generally well tolerated, but patch test if you have known sensitivities to any listed ingredient
• Discontinue use if irritation, redness, or breakouts occur
• Unverified naming detail: VT Cosmetics has not published an official explanation of what the "S4" designation stands for; product listings do not define it, and it should be treated as a branded internal product code rather than a confirmed ingredient or concentration reference until the brand clarifies it
