NCT ID: NCT03811977 Completed - Dermis Density Clinical Trials

The Effect of 12-Week Dietary Intake of Lutein on Minimal Erythema Dose and Other Skin Parameters

VIST Lutein
Start date: March 4, 2019
Phase: N/A
Study type: Interventional

The double-center, randomized, placebo-controlled, one-period effectiveness study will include 30 subjects (women, aged between 25 to 55 years, Fitzpatrick phototype II and III). Subjects will be divided in two groups, 15 in each. One group (test group) will receive investigational product - lutein syrup (4 mg/mL; daily dose 20 mg) and the other (placebo group) placebo syrup. Participants will test continuous administration of placebo or investigational product for 12 weeks in order to demonstrate and assess multiple-dose effects. The primary objective is to assess the photoprotective potential of the investigational product in relation to placebo product. The secondary objectives are to assess effects of investigational product on dermis density and skin viscoelasticity after 12 weeks of dietary supplementation.
