Vita C-25 Dual Care Set

A two-step brightening ritual powered by warmth and cooling

This dual-care set pairs a high-potency ampoule containing 20% pure vitamin C and 5% vitamin C derivative with a soothing panthenol cream. When you apply the ampoule, stabilized vitamin C generates a gentle warming sensation that helps open pores and enhance ingredient absorption. Follow with the panthenol cream, which delivers a cooling effect to close pores and seal in a moisture barrier. To minimize oxidation of light- and oxygen-sensitive vitamin C, the ampoule is packaged in four separate 2.1 g bottles, each sized for approximately 3 drops per use.

Clinical brightening results after 4 weeks of use

A human application test confirmed the following improvements.

• Up to 38.5% reduction in deep hyperpigmentation area (after 1 week)
• Up to 35.3% reduction in surface hyperpigmentation area (after 1 week)
• Up to 12.3% improvement in under-eye pigmentation (after 1 week)
• Up to 9.9% improvement in overall skin tone (after 4 weeks)

Dermatologist-tested. Suitable for sensitive skin.

A synergistic formula built on vitamin C and panthenol

The ampoule combines ascorbic acid, pure vitamin C that inhibits melanin production, with ethyl ascorbyl ether, a vitamin C derivative that penetrates deeply with minimal irritation. The cream features 25,000 ppm panthenol to strengthen and soothe the skin barrier, plus hyaluronic acid for hydration, niacinamide for tone-evening, and adenosine for wrinkle care. Together, they target brightening while supporting overall skin health. Ideal for those noticing dark spots and hyperpigmentation, or anyone seeking high-concentration vitamin C without the irritation. Use 3 to 4 times per week in the evening after cleansing. Apply the ampoule first, let it absorb, then finish with the cream.

After toner, before cream — in the essence step

Use Vita C-25 Ampoule right after cleansing and toning. The key is to apply the ampoule on freshly toned skin, before anything else. High-concentration vitamin C absorbs best when it makes direct contact with your skin, so skip any other layers between toner and ampoule. Once the ampoule has fully absorbed, follow with Aqua SH Panthenol Cream to lock in the active ingredients with a moisture barrier.

Evening routine only, 3–4 times per week

Due to the high concentration of vitamin C, we recommend using this ampoule in the evening. Start with 3–4 times per week and adjust based on how your skin responds. If you do use it during the day, applying sunscreen thoroughly is essential.

2–3 drops is enough — allow 1 minute to absorb

Two to three drops is all you need to cover your entire face. Warm the ampoule between your palms, then gently press and smooth it over your skin. Give it about a minute to absorb. A subtle warming sensation is normal — it's a sign the vitamin C is activating. Follow with a moderate amount of Panthenol Cream, massaging it in until absorbed. You'll feel a cooling effect as your skin calms.

Routine combinations by skin concern

• Targeting dark spots and hyperpigmentation: Use Vita C-25 Ampoule in the evening followed by Panthenol Cream. In the morning, continue tone-evening with a niacinamide serum
• Dry and sensitive skin: Layer an extra veil of hydrating toner before the ampoule to stabilize your skin and minimize irritation
• Dull under-eye area: Gently tap a small amount of ampoule onto pigmented areas under the eyes to help improve the appearance of dark circles

Before you use, please note

• Avoid use on days when your skin is irritated, such as right after exfoliation, peeling treatments, or professional procedures
• A yellow tint to the ampoule is normal, but if it turns brown, it has oxidized and should not be used
• Use quickly after opening and store in a cool place away from direct sunlight
• If redness or discomfort persists during use, discontinue and consult a dermatologist
