| Effect | Increase |
| Trial Design | Double blind |
| Trial Length | 1-6 months |
| Number of Subjects | 66 |
| Sex | Both Genders |
| Age Range | 18-29, 30-44, 45-64 |
Two studies were conducted with either oral ingestion of astaxanthin (3mg with meals) or topical application of astaxanthin where a cream contains 5% of an astaxanthin containing oil; due to the oil containing only 0.094% astaxanthin, the ultimate concentration was 78.9µM.
Skin elasticity in the cheek and crows feet (side of the eye) were significantly improved and age spots reduced. Although a significant reduction in TEWL was noted, there was no whole-group improvement in moisture content although a subset of persons with dry skin noted improvement and sebum oil in men showed a mild reducing effect (not statistically significant).
