Brief 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.

Primary Outcomes (2)
Change of pigmentation by physician's assessment
The pigment clearance was assessed using a 5-grade percentage improvement scale grade 1, \<0% \[worse\]; grade 2, 0%-25% improvement; grade 3, 26%-50% improvement; grade 4, 51%-75% improvement; grade 5, 76%-100% improvement -\> higher score means better outcomes
Change from baseline pigmentation at 4 weeks

Study Arms (2)
epidermal growth factor (EGF) containing ointment group
EXPERIMENTALThe subjects received one session of laser treatment with a Q-swithced (QS) 532-nm Nd:yttrium aluminum garnet (YAG) laser 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. The subjects then applied the epidermal growth factor (EGF) ointment twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.
Vehicle ointment group
PLACEBO COMPARATORThe 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. The subjects then applied the vehicle ointment twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.
Interventions
The subjects applied the epidermal growth factor (EGF) ointment twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.
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.
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.
Eligibility Criteria

- Clinical diagnosis of solar lentigines that occurred after adulthood
- age of 20 years or older.
You may not qualify if:
- uncontrolled systemic or chronic disease
- hypersensitivity to the ingredients of the ointment
- current use of skin whitening agents
- a history of other laser treatments within the past 6 months
