Cosmetic composition containing extract of
The present disclosure relates to a cosmetic composition containing an extract of Cyperus rotundus extracted using warm microbubbles. The extract inhibits nitric oxide (NO) production and exhibits excellent anti-inflammatory efficacy by inhibiting the expression of interleukin 6 (IL-6), cyclooxygenase-2 (COX-2), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α), which are inflammatory expression factors. In addition, the extract enhances the expression of aquaporin-3 (AQP-3), hyaluronan synthase 2 (HAS-2), claudin-1 (CLDN-1), cadherin 1 (CDH1), filaggrin (FLG), and involucrin (IVL), which are genes related to the skin barrier and moisturizing. Thus, when using the extract for cosmetic products, excellent effects can be exhibited in skin soothing, moisturizing, enhancement of the skin barrier, relief of irritation such as erythema, relief of pruritus, and the like, so the extract can be usefully applied to multi-care products that improve skin conditions.
1 . A method of providing anti-inflammatory and skin-soothing effects to a subject in need thereof, comprising:
preparing a composition containing an extract of Cyperus rotundus extracted using warm microbubbles, and
