Hoshisu Vitamin C Serum 20 ml – Triple Vitamin C + Vitamin B6, Lightweight Brightening Essence

Hoshisu Vitamin C Serum is a lightweight, fast-absorbing essence that blends three forms of Vitamin C with Vitamin B6 to help brighten and hydrate skin without greasy residue.

Made in Japan and repackaged with clear North American labeling, this 20 ml drop-type tube delivers an easy-to-apply concentrated serum designed to support an even-looking complexion and a refreshed sheen. The formula combines multiple Vitamin C derivatives, Vitamin B6, and botanical extracts to target dullness while providing soothing moisture and a comfortable finish suitable for daily skincare routines.

How does this serum help skin tone and radiance?

The serum uses three complementary Vitamin C derivatives to address surface dullness and promote a more luminous appearance. These forms are selected for stability and skin compatibility so you get brightening benefits with minimal irritation risk when used as directed.

• Three Vitamin C derivatives for broader coverage of antioxidant activity.
• Vitamin B6 supports skin comfort and helps maintain an even appearance.
• Alpinia extract adds a soothing botanical element to reduce the look of stress.
• Fast-absorbing base avoids a greasy finish, leaving skin balanced.

Is the texture suitable for layering in my routine?

The lightweight serum is formulated to sink in quickly and works well under moisturizers and sunscreens. Because it absorbs without leaving a heavy film, it fits into morning or evening routines and pairs easily with toners, creams, or oils.

• Thin, essence-like texture for seamless layering.
• Drop-type tube dispenses controlled amounts for targeted application.
• Leaves minimal residue so subsequent products can perform normally.
• Can be used before heavier treatments or under SPF in daytime routines.

What should I know about safety and everyday use?

Hoshisu Vitamin C Serum is for external use; always patch test before full application and stop use if irritation occurs. Follow the directions on the package and introduce the product gradually if your skin is sensitive to active ingredients.

• Apply after cleansing and toning, then spread gently with fingertips.
• Use sunscreen during the day when incorporating Vitamin C into a morning routine.
• If irritation develops, discontinue use and consult a dermatologist as needed.
• Store according to label instructions to preserve ingredient stability.
