Vitamin C is the gold standard for bright skin — but most people use it wrong. Here are the 5 mistakes we see everywhere, and the simple fixes.
1. Using it in the morning without SPF. Vitamin C and sunscreen are a power couple; alone, C can't shield you.
2. Mixing with strong acids. Layering AHA/BHA at the same time can irritate. Alternate nights instead.
3. Storing it in the bathroom. Heat and light oxidize the formula. Keep it cool and dark.
4. Using too much. 3-4 drops is plenty. More product doesn't mean more glow.
5. Quitting too soon. Brightening takes 4-6 weeks of consistent use. Stay the course.
