Vitamin C Serum: The Brightener
Goal: Fade dark spots, protect against pollution, and boost glow.
How to Use Vitamin C Serum
- Morning routine: Vitamin C works best in the morning.
- Cleanse: Wash your face and pat dry.
- The portion: Use 3-4 drops from the dropper into your palm.
- Apply: Press your palms together, then press the serum onto your cheeks, forehead, and neck.
- Wait: Let it absorb for 1-2 minutes so it does not pill (roll up) under other products.
- Follow up: Apply your moisturizer and then your sunscreen.
Pro Tip
If the liquid in the bottle turns dark brown or orange, it has oxidized (gone bad). Throw it away.
