COMPOSITION EXTERNALLY USED FOR SUBACID SKIN AND COSMETIC MATERIAL INCLUDING SAME

摘要

The present invention relates to a composition with a pH of 3-5, preferably 3-4.5 externally used for a subacid skin composed of a multi-lamellar emulsion including pH modulation agent and a polymeric thickening agent, and a composition externally used for a subacid skin according to the present invention maintains stably a multi-lamellar emulsion with a skin barrier function composed of a large amount of a lipophilic skin care material at a relatively low pH condition so as to enhance or recover the skin barrier function through normalizing the skin pH, thus recovering and maintaining a healthy skin, making the skin effectively moisturized, maintaining a proper viscosity so as to prevent the phase separation, and having almost no skin penetration so as to eliminate the problem of stimulating the skin.
