The present invention relates to a composition for alleviating atopic dermatitis or improving skin moisturization, containing a Pyrus ussuriensis extract. A Sanhyang Pyrus ussuriensis leaf extract of the present invention increases the production of hyaluronic acid in cells, and exhibits an effect of reducing the expression of thymus and activation regulated chemokine (TARC), which is an atopy-inducing factor, thereby having an excellent moisturizing effect or atopic alleviation effect. Therefore, the composition can be used as a material for cosmetics and food for skin moisturizing and alleviation of atopy. 본 발명은 산돌배 추출물을 포함하는 아토피성 피부염 개선용 또는 피부보습 개선용 조성물에 관한 것으로, 본 발명의 "산향" 산돌배 잎 추출물은 세포내에서 히알루론산의 생성을 증가시키고, 아토피 유발인자인 TARC(Thymus and activation regulated chemokine)의 발현은 감소시키는 효과를 나타내므로, 우수한 보습효과 또는 아토피 개선효과를 가진다. 따라서, 피부보습 및 아토피의 개선을 위한 화장품, 식품의 소재로 사용할 수 있다.
