Zeaxanthin May Help Reduce Wrinkles
Skin aging and wrinkles are partially due to prolonged oxidative stress. A recent study suggests that taking a daily supplement of the carotenoid zeaxanthin in combination with sea buckthorn fruit oil and wheat ceramides may decrease the formation of harmful free radicals and reduce wrinkles in women.
Participants in the study included 31 women with an average age of 60 who took part in one of three interventions over the course of 12 weeks: supplements only, supplements plus a topical cream, or a placebo. The supplements contained zexanthin, sea buckthorn fruit oil, wheat ceramides, alpha lipoic acid, green tea, red clover leaf, gotu cola seed, maritime pine bark, and vitamins C, E, and D3.
Both supplement groups showed statistically significant improvements in hydration scores from baseline levels after 12 weeks. No change was noted in the placebo group. Both supplement groups also had a statistically significant difference from baseline scores in average wrinkle severity at week 12 when compared with the placebo.
Additionally, the supplement plus topical cream group had reduced total wrinkle count after four weeks. No change was seen in the other two groups.
Researchers from IRSI, ZSS, and Nutribloom conducted the study. It was published online ahead of print on June 17, 2016, in the Journal of Cosmetic Dermatology.
Zeaxanthin is most commonly known for being one of only two carotenoids — the other being lutein — that can build the yellow macular pigment in the eye that protects against damaging blue light. You can increase your lutein and zeaxanthin levels by consuming more green leafy vegetables, corn, and egg yolk.
