Efficacy of topical vitamin C in melasma and photoaging: A systematic review

Conclusion: This study revealed that vitamin C is effective in treating uneven, wrinkled skin and has depigmenting properties, but long-term use may be needed to achieve noticeable changes. Q-switched Nd:YAG laser-associated protocols appear beneficial in enhancing vitamin C effects. Topical vitamin C may be a suitable alternative for melasma and photoaging, but more studies are needed to confirm these results and assess the ideal vitamin C concentration.
