The ultimate radiance booster—concentrated with 23% Pure Vitamin C to target stubborn hyperpigmentation, brighten dark spots, and diminish fine lines in a fast-absorbing formula.
Product Description
The Isntree Hyper Vitamin C 23 Serum is a high-performance antioxidant treatment designed to revitalize dull and uneven skin. Featuring a potent 23% concentration of Pure Vitamin C (Ascorbic Acid), it actively suppresses melanin production to fade post-acne marks, sun spots, and age spots while boosting collagen synthesis for firmer skin.
To ensure stability and maximize efficacy, this serum is enriched with Vitamin E (Tocopherol), which works synergistically with Vitamin C to provide superior protection against environmental damage. The formula is balanced with Panthenol to soothe and strengthen the skin barrier and Birch Juice for deep, weightless hydration. Its lightweight, watery texture absorbs quickly without the heavy, oily residue typical of high-dose Vitamin C products, making it a "must-have" for achieving a clear, luminous "glass skin" complexion.
Key Features
23% High-Strength Pure Vitamin C: A clinically effective dose that delivers intense brightening and anti-aging benefits.
Synergistic Antioxidant Duo: Vitamin C and Vitamin E combined provide a much stronger defense against free radicals and UV damage.
Hyperpigmentation Eraser: Specifically targets dark spots and uneven skin tone for visible results in as little as 2 weeks.
Soothing & Hydrating: Panthenol and Birch Juice mitigate potential irritation and prevent the skin from feeling tight or dry.
Fresh & Fast-Absorbing: A non-sticky, thin consistency that layers perfectly under moisturizer and sunscreen.
How to Use
Preparation: After cleansing and toning, dispense 2–3 drops onto your palms.
Application: Gently spread across the entire face, avoiding the eye and mouth areas. Pat lightly to aid absorption.
Frequency: For new users or sensitive skin, it is recommended to use once every 3–4 days and gradually increase frequency as your skin adjusts.
Daytime Care: If applied in the morning, you must follow with SPF 30+ to prevent oxidation and protect your skin.
Storage: Due to the nature of pure Vitamin C, store in a cool, dark place (or refrigerator) and keep the cap tightly closed to prevent oxidation. Use within 2 months after opening.
