Synopsis The aim of the study was to investigate the potential of a fucoxanthin concentrate prepared from Phaeodactylum tricornutum as a wrinkle care cosmetic agent. The concentrate (up to 25 μg/ml) did not affect the proliferation of human fi broblasts. In addition, the concentrate signifi cantly increased procollagen synthesis in the fi broblasts at 12.5 and 25 μg/ml however, it signifi cantly decreased the expression of matrix metalloproteinase (MMP)-1, MMP-2, and MMP-9 at 25 μg/ml. In a follow-up study, a wrinkle care cream containing 0.03% of fucoxanthin concentrate was prepared and tested in women (aged 35–50 years, n = 21) for 8 weeks. The cream was applied twice daily. Safety assessment of the cream was carried out visually. In addition, interviews were conducted to investigate if adverse events such as erythema, edema, scaling, itching, stinging, burning, tightness, or prickling had occurred. No symptoms that threaten skin safety were reported. Evaluation of wrinkles around the eyes using the replica method showed a statistically signifi cant decrease in wrinkles at week 8. Moreover, skin moisture and elasticity increased signifi cantly from week 4. These results suggest that the fucoxanthin concentrate has no adverse effects on the skin and can be used as an active ingredient in wrinkle care cosmetics. INT RODUCTION The skin is directly exposed to the external environment therefore, it plays an important role in maintaining homeostasis of the human body by protecting it from external factors such as temperature, humidity, pathogens, and ultraviolet (UV) rays (1). However, skin cells are damaged by various harmful factors, such as pollutants, strong UV rays, stress, and malnutrition (2–5). As aging progresses and damages caused by the aforementioned factors accumulate, changes in the biochemical activities of the skin occur, which lead to Address all correspondence to Jongkeun Choi at jkchoi@chungwoon.ac.kr.
