Topical and internal skin preparations containing an extract of soapwort cultivated under artificial light with a specific wavelength range.

Abstract

The present invention provides topical and internal skin preparations containing an extract of soapwort cultivated under artificial light with a specific wavelength range. [Solution] The soapwort of the present invention is cultivated by irradiating it with artificial light having a specific wavelength range, and the extract exhibits excellent collagen production promoting effect, MMP inhibitory effect, hyaluronic acid production promoting effect, cell proliferation promoting effect, and antioxidant effect. Furthermore, topical or internal skin preparations containing these effects are particularly effective and also exhibit excellent safety and stability. The soapwort extract of the present invention can be used not only in the field of beauty, such as preventing skin aging, but also in the field of medicine, such as suppressing functional decline due to aging, and is expected to be applied to cosmetics, foods, quasi-drugs, and pharmaceuticals.

Claims
