Kerstin Florian Serum C Infusion is a lightweight daily Vitamin C serum that brightens skin, supports collagen production, and helps minimize the look of fine lines while firming and toning.

This concentrated 1 fl oz facial serum blends a potent Vitamin C+ Complex with regenerative amino acids and botanical extracts to target uneven tone, loss of firmness and early signs of aging. The formula is designed for daily layering under moisturizer and sunscreen, providing a spa-inspired treatment at home that focuses on antioxidant support and skin matrix renewal without heavy or greasy residue.

How does this serum improve skin brightness and uneven tone?

The Vitamin C+ Complex is engineered to reduce visible melanin formation and brighten dull complexions while protecting against oxidative stress. Regular application helps even skin tone and refines the look of imperfections, delivering a clearer, more luminous appearance over time.

• Contains a concentrated Vitamin C+ Complex for targeted brightening.
• Helps reduce melanin formation to diminish dark spots and discoloration.
• Lightweight texture absorbs quickly for daily use under moisturizer.

Will this serum help with fine lines and loss of firmness?

This formula combines regenerative amino acids with Vitamin C to support the skin’s structural matrix, helping to firm and plump the surface. With consistent use, fine lines appear softer and skin looks more resilient and toned.

• Amino acids encourage collagen-supporting processes that improve elasticity.
• Boosts firmness and helps smooth the appearance of fine lines.
• Non-greasy finish makes it suitable for morning and evening routines.

How should I incorporate Serum C Infusion into my skincare routine?

Apply the serum to clean, dry skin, avoiding the delicate eye area, then follow with your preferred moisturizer. Because Vitamin C enhances sun sensitivity reduction of photo-damage, use a broad-spectrum sunscreen during the day to protect results.

• Use daily after cleansing and before moisturizing.
• Allow serum to fully absorb before layering creams or makeup.
• Pair with SPF in the morning; consider richer creams at night for restoration.

What natural ingredients support the formula’s performance?

Botanical extracts such as algae and bitter orange oil are included to soothe and support skin balance while delivering additional antioxidant properties. The blend emphasizes clean, science-driven ingredients for a comforting, spa-like application that complements efficacy.

• Algae extract for calming and mineral support.
• Bitter orange oil for a gentle, uplifting botanical aroma and tone-balancing benefits.
• Plant-forward formulation paired with lab-stable Vitamin C derivatives and amino acids.

Who is this for: Serum C Infusion is suited to anyone seeking a daily antioxidant serum to brighten dull skin, reduce the visible appearance of fine lines, and support firmness—ideal for normal, combination, and aging skin types that want a lightweight, easily layered treatment. If you use active ingredients, patch-test first and introduce it gradually with sunscreen in your daytime program.
