  • Age ≥ 50
  • female patient must be in post-menopause (> 2 years)
  • Clinically and dermoscopic confirmed solar lentigines on both sides back of the hands

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Pigmanorm Cream, Q-switched Ruby laser,solar lentigines

Arm Description

Solar lentigines on the left back of the hand side are treated with Pigmanorm Cream once a day for 7 weeks. Solar lentigines on the right back of the hand side are treated with a Q-switched Ruby laser at Baseline and if required at day 28.

Outcomes

Primary Outcome Measures

Evaluation of clearing of pigmentation
The primary efficacy objective is to evaluate the clearing of pigmentation(percentage of clearing) following a quartile scale of poor (25% clearance), fair (26-50% clearance), good (51-75% clearance), and excellent (76-100% clearance).

Secondary Outcome Measures

Evaluation of safety profile
Adverse effects are noted at each visit.
Change from Baseline in Pigmentation at day 140
The clearing of pigmentation (percentage of clearing) following a quartile scale of poor (25% clearance), fair (26-50% clearance), good (51-75% clearance), and excellent (76-100% clearance) is assessed at day 140 from Baseline ( = 3 months after finishing treatment).

5. Study Description

Brief Summary
Benign pigmented lesions as solar lentigines are a common finding in Caucasian individuals. Their removal may be requested for aesthetic reasons. The goal of the study is comparing the efficacy and tolerance of two different therapy modalities established for treating solar lentigines. The right back of the hand side will be treated with the Q-switched SINON Rubin 694nm Laser, the left back of the hand side with a hydrochinon containing bleaching cream (Pigmanorm® cream). The investigators estimate that a physical therapy with a Q-switched Rubin laser system is more effective in the removal of solar lentigines than a topical chemical therapy with a hydrochinon containing bleaching cream.
