Abstract

The invention discloses a composition for repairing a skin barrier and improving a sunscreen index, a preparation method and application of the composition. The composition for repairing the skin barrier and improving the sunscreen index comprises kappaphycus alvarezii extract / caesalpinia spinosa fruit extract and a hyaluronic acid cross-linked polymer or a hyaluronate cross-linked polymer. According to the composition, the two components are synergistically compounded to form a compact network structure with smaller grid aperture, and powder (titanium dioxide or zinc oxide and the like) can be better dispersed in sunscreen and make-up products, so that the powder is not easy to agglomerate, and the stability is improved; and meanwhile, the composition can form a layer of breathable reticular protective film on the surface of skin, so that the skin barrier repairing capability can be enhanced, and the sunscreen index is enhanced. When the composition is added into products with high sun-screening index requirements, the use amount of a sun-screening agent can be reduced, the irritation of the products is reduced, and the skin-care functions of the sunscreen and make-up products areincreased.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a composition for repairing skin barrier and improving sun protection index, a preparation method and an application thereof. Background technique [0002] In recent years, the external environment, such as harmful substances in PM2.5, dust, pollen, and smog particles, and even virus particles have caused great damage to the skin, and consumers have overused their own cosmetics, resulting in imbalanced skin surface flora or The use of improper cosmetics causes skin allergies and other problems, which greatly damages the skin barrier. [0003] With people's increasing understanding of sunscreen knowledge, the use of sunscreen products will increase, which will inevitably lead to the cumulative use of sunscreen agents on the skin, and the potential damage to the skin cannot be ignored. The products are more popular, how to reduce the amount of sunscreen agent under high SPF has ...
