Background/Objective: This study aims at the evaluation of the efficacy and safety of a combination therapy based on pidobenzone 4% and fractional CO2 laser or cryotherapy in the treatment of solar lentigines and the prevention of eventual posttreatment hyperchromia. Methods: Efficacy was clinically evaluated by grading the pigmentation level with the Skin Tone Color Scale (STCS), and by grading patients' impression through a Visual Analog Scale (VAS). Results: Our study shows that the associated treatment was safe and that it improves the therapeutic results on solar lentigines and prevents postiatrogenic hyperpigmentation compared with physical therapy alone. Conclusion: The combination of cryotherapy and pidobenzone 4% has been found to be the most useful treatment.
