⚡ Pro Tips for Vitamin C Success
-
Store in a cool, dark place. Vitamin C degrades with heat, light, and air.
-
Look for airtight packaging (pumps > droppers).
-
Slight tingling is normal, but stinging means it's too strong or used on broken skin.
-
Always pair with SPF. It boosts protection and prevents oxidation.
