Tips for Getting the Most Out of Your Vitamin C Serum

• Apply in the morning: Vitamin C works best during the day to protect your skin from free radicals.
• Use sunscreen: Always follow with SPF to avoid sun sensitivity.
• Store it right: Keep your serum in a cool, dark place to maintain potency.
• Start slow: 3–4 times a week is enough in the beginning, then gradually increase usage.

And remember — consistency is key. Results won’t happen overnight, but give it a few weeks and your skin will thank you.
