Isntree Hyper Vitamin C 23 Serum 20mL

Isntree Hyper Vitamin C 23 Serum is a concentrated facial treatment containing 23% ascorbic acid, the pure form of vitamin C. It is designed for dullness, uneven-looking tone and the appearance of dark spots. Tocopherol, or vitamin E, complements the formula’s antioxidant-focused approach, while a vitamin C derivative is also present in the ingredient list.

Betaine, hydroxyethyl urea, birch juice and panthenol add hydrating and skin-conditioning support to the lightweight base. Apply a small amount after toner and before moisturizer. Because of the high vitamin C concentration, start once every three to four days, watch how your skin responds and protect the formula from heat and direct sunlight.

23% pure vitamin C with hydrating support

Hyper Vitamin C 23 uses a high concentration of ascorbic acid in a lightweight serum rather than a rich cream. The supporting ingredients are selected to pair brightening-focused care with moisture and skin comfort. Its compact dropper bottle allows a measured application, and careful storage helps protect this vitamin C formula between uses.

• 23% ascorbic acid: Pure vitamin C is the second listed ingredient at 23%, giving this serum its concentrated brightening identity and making cautious introduction essential.
• Vitamin E pairing: Tocopherol adds vitamin E to the formula, complementing its antioxidant-focused skincare approach alongside ascorbic acid and ethyl ascorbyl ether.
• Birch juice and panthenol: Betula platyphylla japonica juice and panthenol provide hydrating and conditioning support, helping balance the active focus with skin comfort.
• Moisture-binding base: Betaine, polyglycerin-3 and hydroxyethyl urea help hold moisture in a light serum texture, rather than relying on a heavy layer of oils.
• Controlled dropper application: The supplied dropper makes it easy to dispense a few drops. Close it securely after each use and protect the bottle from light and heat.

Focused radiance care for uneven-looking skin

This serum is intended for people looking for a dedicated vitamin C step, particularly when dullness and uneven-looking tone are their main concerns. Its moisture-supporting ingredients add comfort to the lightweight texture, but a high concentration can still feel strong. Start slowly and let your skin’s response guide ongoing use.

• Brighter-looking complexion: Ascorbic acid supports a more radiant appearance and helps improve the look of dullness as part of a consistent skincare routine.
• More even-looking tone: The formula targets the appearance of dark spots and discoloration, helping the complexion look more uniform over time rather than providing instant coverage.
• Hydration alongside actives: Humectants, birch juice and panthenol add moisture and conditioning care, so the serum addresses skin feel as well as visible radiance.
• Lightweight layering: The fluid texture fits beneath moisturizer, giving a focused vitamin C step without requiring a thick treatment layer or replacing your sunscreen.
