The present invention relates to a method for preparing a composition for anti-inflammation and skin regeneration using polydeoxyribonucleotide (PDRN), a composition for anti-inflammation and skin regeneration prepared by the method, or a wound dressing comprising the same. The low molecular weight polydeoxyribonucleotide (PDRN) contained in the composition of the present invention has a size of 1,000 Da or less, which has improved skin penetration rate compared to the conventional PDRN. In addition, the composition of the present invention effectively inhibits inflammation of the skin without inducing skin side effects, and has a skin cell regeneration effect. Thus, the composition of the present invention can be used as a pharmaceutical composition, a cosmetic composition or a wound dressing. |
