Which is Better for Hyperpigmentation, Vitamin C or Niacinamide?
Both vitamin C and niacinamide effectively reduce hyperpigmentation, but they work through different mechanisms. There isn't a single "better" ingredient; the ideal choice depends on individual skin type and concerns.

Practical Considerations
- Introduce Gradually: Start with low concentrations and gradually increase to gauge your skin's tolerance.
- Patch Test: Before applying any new product to your entire face, conduct a patch test on a small area to check for any adverse reactions.
- Consult a Dermatologist: If you have severe hyperpigmentation or sensitive skin, consult a dermatologist for personalized advice.
