✓ Ideal for dark spots and post-acne discoloration
✓ Great for pigmentation-prone skin
✓ Best suited to experienced Vitamin C users
✓ Introduce gradually if skin is sensitive

Key Ingredients

• Pure Vitamin C / Ascorbic Acid (23%): A potent antioxidant that helps brighten uneven skin tone, improve the appearance of dark spots, and support collagen-related skin firmness.
• Tocotrienols (Vitamin E): Provide complementary antioxidant care and help support the formula's Vitamin C benefits.
• Sodium Hyaluronate: Helps attract and retain moisture to maintain skin hydration and plumpness.
• Allantoin: Helps soothe and maintain skin comfort during high-strength active care.
• Super Vitamin E: Provides additional antioxidant support against environmental oxidative stress.

How to Use
After cleansing and toning, shake the bottle lightly and apply a few drops evenly over the face, avoiding the immediate eye and lip areas. Gently pat until absorbed and follow with moisturizer.

If new to high-strength Vitamin C, begin 2–3 times per week and gradually increase according to skin tolerance. Always apply broad-spectrum sunscreen during the day.

Because pure Vitamin C is sensitive to light, heat, and air, keep the bottle tightly closed and follow the manufacturer's storage instructions to help maintain freshness.
