<p>It is intended to provide compounding ingredients for cosmetics for improving skinditch density and cosmetics. The present invention provides compounding ingredients for cosmetics containing, as an active ingredient, nucleoprotein and/or DNA or RNA enzymatic or hydrolytic degradation product(s), a deoxyoligonucleotide, deoxymononucleotide, oligopeptide, oligonucleotide, or mononucleotide separated from the degradation product, or a mixture of at least two members selected from the degradation products and the compounds, and cosmetics containing the compounding ingredients for costmetics. The active ingredients such as the deoxyoligonucleotide have a relatively small molecular weight and as such, are easily transdermally absorbed. The transdermally absorbed active ingredients promote skin cellular regeneration or activation. Thus, these active ingredients, when applied to the epidermis in the face, produce the effect of improving skinditch density (texture), the effect of improving the water retention ability or sebum level balance of the skin, and the effect of preventing wrinkles and the like.</p> |
