Brightening, antioxidant-rich vitamin C serum designed to help even skin tone, fade dark spots, and boost radiance.

Why you’ll love it

• Potent 23% L‑ascorbic acid formulation for visible brightening and antioxidant protection
• Lightweight, fast-absorbing serum that layers under moisturizers and makeup
• Helps reduce the appearance of hyperpigmentation, dullness, and uneven texture
• Compact 20 ml bottle — great for trying a high-concentration vitamin C without committing to a large size

Key benefits

• Brightens and evens skin tone
• Helps fade dark spots and post-inflammatory hyperpigmentation over time
• Protects skin from free-radical damage when used with daytime SPF
• Enhances overall radiance and skin clarity

Texture & scent

• Slightly viscous, fast-absorbing serum
• Clear to pale yellow in color (may deepen over time due to vitamin C oxidation)
• Light, natural citrus-like scent for many users

How to use

1. Cleanse and tone.
2. Apply 2–3 drops of the serum to dry skin, gently patting over face and neck.
3. Follow with moisturizer.
4. In the morning, always finish with broad‑spectrum sunscreen (SPF 30+).
   • Start slowly if new to high‑strength vitamin C: use every other day, then increase frequency as tolerated.

Suitable for

• Those looking to target dullness, uneven tone, and dark spots
• Normal, dry, combination, and oily skin types — patch test recommended for sensitive skin

Precautions & tips

• Patch test before first use.
• Avoid combining with other strong actives (e.g., high‑strength AHA/BHA or retinoids) in the same application until skin tolerance is established.
• Store in a cool, dark place and keep the cap tightly closed to help maintain potency. Some discoloration over time is normal and does not necessarily indicate spoilage.
• Use daily sunscreen when using vitamin C products to protect results and prevent further pigmentation.
