This formula is the "Goldilocks" of serums—not too weak, not too strong—making it perfect for:

• Beginners who want to move beyond basic Vitamin C derivatives.
• Anyone frustrated by a "shadowy" or uneven skin tone.
• People with oily or combination skin who dislike heavy, oil-based serums.
• Individuals looking for a daily antioxidant boost that doesn't cause a stinging sensation.
• Note: Keeping this bottle in the fridge is a great way to maintain its freshness and provide a cooling effect upon application.

• Preparation: Wash your face and apply your usual toner. Ensure your skin is slightly damp or dry.
• Application: Tilt your head back and apply 2–3 drops directly to the skin, or onto your fingertips.
• Distribution: Gently spread the serum across your face using circular motions, avoiding the immediate eye area.
• Integration: Wait a few moments for the serum to fully sink in before layering your next product.
• Sun Safety: Always apply a high-factor sunscreen (SPF 30 or above) if using this product during the day, as Vitamin C can make skin more sensitive to UV rays.
