The Science
Vitamin C Formulation Superiority
Why LUMIÈRE's Vitamin C works better
L-Ascorbic Acid Stabilization
Our pH-optimized formula (pH 3.2-3.5) keeps L-Ascorbic Acid stable and highly absorbable. The encapsulation system prevents oxidation, ensuring maximum potency throughout shelf life.
Advanced Delivery System
Liposomal encapsulation allows 15% L-Ascorbic Acid to penetrate the epidermis efficiently without irritation. Competitors using basic formulations achieve only 8-10% bioavailability.
Synergistic Antioxidant Complex
Vitamin E (1%) and Ferulic Acid (0.5%) work together to create a photoprotective boost that's 8x more effective than Vitamin C alone. This triple-antioxidant system is clinically proven.
Board-Certified Dermatologist
Dr. Elena Rodriguez, MD
"L-Ascorbic Acid is the gold standard in skincare science. LUMIÈRE's formulation is particularly impressive because it maintains stability through both encapsulation and pH optimization. I recommend this to patients seeking visible brightening and anti-aging benefits. Start with twice weekly if you have sensitive skin, then build to daily use."
Dr. Rodriguez specializes in anti-aging dermatology and has published research on antioxidant delivery systems in skincare.

2

⊘
NOT Vitamin C (use in AM only)
Save Vitamin C for morning for antioxidant defense
3
Evening Treatments (optional)

Repair and restore during sleep
Why This Order Matters: Vitamin C is most effective in acidic pH (3.2-3.5). Applying it to clean, dry skin maximizes penetration. Following with hydrating products seals benefits. Vitamin C in AM provides antioxidant defense against daily UV exposure and pollution. Reserve PM for treatments that complement your skin concerns.
Vitamin C for Your Skin Type
Oily Skin
★★★★★This lightweight serum is perfect for oily skin. The antioxidant benefits without added oil keep your complexion balanced while brightening.
Pro Tips: Use daily. Skip to the moisturizer step and use a lightweight option. The vitamin C will actually help regulate sebum production over time.
Dry Skin
★★★★☆Works well for dry skin when paired with hydration. The brightening benefits are excellent, just ensure you're sealing in moisture.
Pro Tips: Always apply to damp skin with HA serum underneath. Follow with a rich moisturizer or add Ceramide Barrier Cream on top at night.
Combination
★★★★★Ideal for combination skin. The lightweight formula won't overload dry areas while keeping oily zones balanced and radiant.
Pro Tips: Use daily in AM routine. Apply heavier moisturizer to dry areas, lighter to oily zones. Works beautifully as an AM booster before SPF.
Sensitive Skin
★★★☆☆The 15% concentration is potent. Start slowly with patch testing and 2-3x weekly use. Many sensitive skin types tolerate it well after adjustment.
Pro Tips: Patch test first. Start with 2-3x weekly, gradually increase. Apply over a hydrating serum to buffer. Consider starting with a gentler form if irritation occurs.
Mature Skin
★★★★★This is ideal for mature skin. The collagen-supporting and brightening benefits address multiple aging concerns while improving skin luminosity.
Pro Tips: Use daily for best anti-aging results. Pair with eye cream for comprehensive aging reversal. The vitamin C + retinol combo (different times) is gold standard.
Acne-Prone
★★★★☆Good for acne-prone skin thanks to antioxidant and anti-inflammatory benefits. Won't clog pores. Skip other acids on Vitamin C days.
Pro Tips: Use daily or every other day. Avoid mixing with other actives same day. The vitamin C helps with post-inflammatory hyperpigmentation marks.
