Objectives : Fine dust caused by environmental pollution cause oxidative damage and skin aging. In this study, The possibility of using the Codium fragile extract (CFE) as an anti-aging product for skin improvement was evaluated by confirming the protective effect of skin cells from PM10 (particulate matter 10) through inhibition of ROS and MMPs. Methods : In this study, elastase and collagenase inhibitory activities were evaluated. Cell viability was evaluated by treating keratinocytes (HaCaT cell line) with CFE at various concentrations. The cytoprotective effect from PM10 in keratinocyteswas evaluated using the 3-[4,5-dimethylthiazol]-2-yl]-2,5-diphenyl-tetrazoliumbromide (MTT) assay. ROS (reactive oxygen species) was measured in keratinocytes damaged by PM10 using DCF-DA (2′,7′-dichlorofluorescin diacetate) fluorescence staining. As an anti-aging effect of CFE, MMP-1 (matrix metalloproteinase-1) and MMP-1 (matrix metalloproteinase-9) inhibitory activities were evaluated. Results : As a result, CFE decreased the activity of elastase and collagenase. As a result of evaluating the toxicity of CFE, it is non-toxic at a concentration of 10 to 80 ㎍/㎖. Although cell viability of HaCaT cells treated with PM10 decreased, cell viability increased by 38% when treated with CFE 80 ㎍/㎖. Also, ROS decreased by 8.4%, and MMP-1 and MMP-9 decreased at CFE 80 ㎍/㎖. Conclusions : CFE showed excellent cell protection effect, and it is considered that it can be used in anti-aging products for skin improvement by effectively inhibiting ROS and MMPs from keratinocyte damage caused by fine dust.

In this study, the antioxidant and anti-skin aging properties of the Korean marine algae Ishige foliacea were investigated. Solvent extracts from I. foliacea were prepared with 70% ethanol, 80% methanol, and water. The extraction yields of various solvent extracts ranged from 9.55% to 35.12%. In terms of antioxidant activity, the ethanol extract showed the highest ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) radical scavenging activity, nitrite oxide scavenging activity, reducing power, and FRAP (ferric reducing antioxidant power). Regarding anti-skin aging activity, evaluation of the skin whitening and anti-wrinkle activities revealed that the methanol, water, and ethanol extracts possessed the highest tyrosinase (IC₅₀=0.98 mg/mL), elastase (IC₅₀=0.15 mg/mL), and collagenase (IC₅₀=0.06 mg/mL) inhibitory activities, respectively. These results suggest that I. foliacea holds potential as an antioxidant and anti-skin aging substance in food and cosmetic materials.
