Learn how to use a vitamin C booster like the C15 Brightening Super Booster for brighter, more even skin. Follow our step-by-step guide.
Quick answer
Use a vitamin C booster like the C15 Brightening Super Booster in your morning routine after cleansing and before moisturizer and sunscreen for brighter, more even skin.
Why morning is best for vitamin C
Vitamin C is a potent antioxidant that helps protect skin from environmental damage like pollution and UV exposure. Applying it in the morning allows it to work alongside your sunscreen for added protection. The C15 Brightening Super Booster is formulated to be gentle enough for daily use, even for sensitive skin types.
How to layer it with other products
For best results, apply the vitamin C booster to clean, dry skin after cleansing and before moisturizer. Wait a minute for it to absorb, then follow with your moisturizer and sunscreen. Avoid mixing it directly with retinol or strong exfoliants in the same routine—use those at night instead.
Step-by-step guide
- Step 1: Cleanse and pat dry: Start with a clean face. Use your regular cleanser and gently pat skin dry with a soft towel. Vitamin C absorbs best on clean, damp-free skin. Don't apply to wet skin—it dilutes the booster and reduces effectiveness.
- Step 2: Apply the vitamin C booster: Dispense 2-3 drops of the C15 Brightening Super Booster onto your fingertips. Gently press it into your face and neck, avoiding the eye area. Let it absorb for about 30 seconds. A pea-sized amount is enough—more product doesn't mean faster results.
- Step 3: Follow with moisturizer and sunscreen: Apply your regular moisturizer to lock in hydration. Finish with a broad-spectrum sunscreen of at least SPF 30. Vitamin C works best when paired with daily sun protection. Sunscreen is non-negotiable—vitamin C boosts protection but doesn't replace SPF.
