Purpose: Skin pH, an indicator of skin health, is maintained by various organic factors, which include lactate, free amino acid (FAA), and free fatty acid (FFA). As skin ages or with illness, skin pH becomes less acidic, and functional food has been developed to maintain the acidic pH of skin. In th...

피부 산도를 결정하는 요인은 무엇이 있는가? | 피부 건강을 나타내는 주요 지표인 피부 산도(pH)는 피부의 최외층인 표피에서 생성되는 젖산 (lactate), 유리아미노산 (free amino acid, FAA), 유리지방산 (free fatty acid, FFA) 등 여러 인자들의 전체 함량에 의해 결정된다.1-3 이들 인자 중 젖산은 피부 pH의 주요 결정 인자로, 젖산 생성 효소인 젖산 탈수소 효소 (Lactate dehydrogenase, LDH)는 표피에서 호기적인 상태에서도 강한 활성을 갖는 것으로 알려져 있다. | |
피부 산도 증가로 생기는 문제는 무엇이 있는가? | 1 또한 표피의 여러 유리지방산에서 초래되는 약산성이 피부 산도 유지에 기여 하는 것으로 알려져 있다. 건강한 피부는 pH 4~6 범위의 약산성 pH를 유지하는 반면,1,3 아토피 피부염, 여드름 등의 피부 질환 발병 시 피부 pH 증가와 함께 약산성의 환경에서 활성을 나타내는 피부 장벽의 주요 지질인 세라마이드 생성 관련 효소인 glucocerebrosidase 및 sphingomyelinase의 활성이 저하된다. 3,5,6 또한 노화가 진행되는 피부에서는 피부 pH 증가와 함께 히알루론산, 콜라겐 등의 보습 및 주름 생체지표 활성이 저하된다.7 | |
