Whether you're dealing with fine lines, uneven skin tone, or post-acne marks, this lightweight serum works effectively without irritation, making it suitable for daily use. Housed in a sleek 0.67 fl oz bottle, it's perfect for incorporating into any skincare routine.

Key Features and Benefits

• 13% Pure Vitamin C (Ascorbic Acid): A stabilized concentration that brightens skin, reduces hyperpigmentation, and boosts collagen production for firmer, younger-looking skin.
• Vitamin E (Tocopherol): A potent antioxidant that protects against environmental damage, enhances Vitamin C absorption, and nourishes the skin barrier.
• Hyaluronic Acid: Provides intense hydration, plumping the skin and reducing the appearance of fine lines and wrinkles.
• Brightening & Even Tone: Effectively fades dark spots, sun damage, and acne scars, promoting a more uniform complexion.
• Gentle Formula: pH-optimized (pH 3.0-3.5) for maximum efficacy while minimizing irritation. Free from parabens, sulfates, and phthalates.
• Lightweight & Fast-Absorbing: Non-greasy texture that layers beautifully under moisturizer and sunscreen.

How to Use

For best results, use the serum in your morning or evening routine. After cleansing and toning, apply 2-3 drops onto your face and neck, avoiding the eye area. Gently pat until fully absorbed. Follow with a moisturizer and sunscreen (SPF 30+) during the day, as Vitamin C can increase sun sensitivity. Start with every other day to build tolerance, then use daily. Store the bottle in a cool, dark place to maintain stability.

Who It Is For

This serum is ideal for anyone seeking to brighten their complexion, reduce signs of aging, or fade hyperpigmentation. It suits all skin types, including sensitive, oily, and combination skin. Those new to Vitamin C should patch test first. It is especially beneficial for individuals with dull skin, uneven texture, fine lines, or post-inflammatory hyperpigmentation from acne.
