How to Layer Ferulic Acid with Vitamin C

Apply vitamin C serum first on clean skin, then follow with ferulic acid to stabilize and boost antioxidant benefits.

1. Start with clean, dry skin. Cleanse thoroughly and pat skin completely dry. Any residual moisture or product will interfere with vitamin C absorption and reduce the synergy between these ingredients.
2. Apply vitamin C serum first. Use 2-3 drops of your vitamin C serum and press gently into skin. Wait 10-15 minutes for full absorption before moving to the next step—this timing matters for maximum efficacy.
3. Layer ferulic acid on top. Apply your ferulic acid product using gentle patting motions. The ferulic acid will stabilize the vitamin C and extend its antioxidant activity throughout the day.
4. Finish with moisturizer and SPF. Wait another 10 minutes, then apply your regular moisturizer. Always follow with broad-spectrum SPF during the day since vitamin C can increase photosensitivity initially.
