Clinical Trial Summary

Subjects were randomly assigned to groups for treatment with either an EGF-containing ointment (the study group) or the vehicle alone (petrolatum; the control group). The EGF ointment included recombinant human EGF (1 μg/g). Random numbers used for assignment to groups were provided by the randomization function of SAS.

The subjects received one session of laser treatment with a Q-switched (QS) 532-nm Nd:yttrium aluminum garnet (YAG) laser of their solar lentigines after enrollment. . The end point of laser treatment for lentigines was immediate whitening. The subjects then applied the EGF ointment or vehicle twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.

Intervention

Drug:
• epidermal growth factor (EGF)-containing ointment
The subjects applied the epidermal growth factor (EGF) ointment twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.
• Vehicle ointment
To compare the effect of epidermal growth factor (EGF) ointment, the control subjects applied the vehicle ointment twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.

Procedure:
• Q-swithced (QS) 532-nm Nd:yttrium aluminum garnet (YAG) laser
The subjects received one session of laser treatment with a Q-swithced (QS) 532-nm Nd:yttrium aluminum garnet (YAG) laser of their solar lentigines after enrollment. The procedure parameters were as follows: 5-10-ns pulse duration, 3.5-mm spot size, 0.9-1.1-J/cm2 fluence, and 2-Hz frequency. The end point of laser treatment for lentigines was immediate whitening.
