Designed for customers seeking an intensive Vitamin C treatment, the formula pairs pure Vitamin C with moisturizing and antioxidant ingredients to support a smoother, clearer, more luminous complexion.
Texture

✓ Especially suitable for dull or uneven skin tone
✓ 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.
