How to Use Vitamin C Serum Without Wasting It

Apply vitamin C serum to clean, dry skin in the morning, wait for absorption, then follow with moisturizer and SPF.

Half the people using vitamin C serum are doing it wrong and wondering why their expensive bottles aren't working miracles—it's a morning protective step, not a nighttime repair treatment.

1. Start with clean skin. Cleanse your face with your regular cleanser and pat completely dry. Vitamin C needs direct contact with your skin to work, so any residual moisture or product will block absorption.
2. Apply to strategic zones. Squeeze 3-4 drops onto your fingertips and press gently into your face, focusing on areas that see the most sun exposure. Don't rub or massage—just press and let it sink in.
3. Wait before layering. Give the serum 10-15 minutes to fully absorb before applying anything else. Your skin should feel smooth and slightly tacky when it's ready for the next step.
4. Lock it in. Follow with your regular moisturizer, then SPF 30 or higher. The sunscreen isn't optional—vitamin C makes your skin more photosensitive, not less.
