Functional Effects on Skin Translucency and Dullness (1): In Vitro Evaluation
Reduced skin translucency is believed to result from the carbonylation of keratin, the primary component of the stratum corneum. This process alters the fibrous structure of the protein, thereby decreasing light transmission through the skin.
The inhibitory effect of pineapple ceramide on protein carbonylation in the stratum corneum was evaluated using samples collected via the tape-stripping method.
In this study, stratum corneum samples were treated with hypochlorous acid to artificially induce carbonylation. Protein carbonylation was visualized using a fluorescent dye and quantified through image analysis.
The carbonylation level induced by hypochlorous acid alone was defined as 0% inhibition, and the percent inhibition of protein carbonylation was calculated for samples treated with pineapple ceramide.
*Note on in vitro:
In vitro refers to experiments conducted outside a living organism using cultured cells or tissues to evaluate the efficacy and safety of a test substance.
