Brief Summary

This is a single center, randomized, double-blind and placebo controlled clinical study to evaluate the efficacy and safety of brightening microneedle patch on facial solar lentigines. Subjects who are 30 to 65-year-old with solar lentigines on their faces will receive brightening microneedle patches on facial solar lentigines once a day for 4 weeks. Afterwards, facial images and skin detectors will be used to analysis their skin, according to various skin tone indexes and skin response score sheets.

Detailed Description

Method: 35 subjects, Fitzpatrick Skin Type II to IV. Each subject has at least two brown solar lentigines on the face, and the two spots are independent, each with a clear boundary and diameter ≥ 0.5 cm.

This trial includes 1 screening visit (Day -1), wash-out period (2 weeks before the trial), trial period (4 weeks in total), and 3 return visits for detecting (baseline detecting at the end of the wash-out period, the 2nd week and the 4th week of the trial period).

Primary Outcome Measures
NameTimeMethod
the percentage change of skin tone index ITA° value of facial solar lentigines from baseline4 week

measure L\* (luminance) and b\* (yellow/blue component) values at baseline and 4th week by color meter (CR-400 Chroma Meter) to assess the ITA° percentage change. (ITA°=tangent arc((L\*-50)/b\*) 180/3.14159)
