Compositions comprising sun-care actives and self adapting polymers are disclosed. Self adapting polymers align themselves with the hydrophilic group pointing to the surface during application thus delivering an aesthetically pleasing surface to the consumers with a pleasant after feel. These polymers then rearrange upon contact with water so that the hydrophobic groups now point to the surface which then increases the water resistance of the formulation.

The invention provides a Pickering emulsion type skin care product. The Pickering emulsion type skin care product comprises Silsoft EAU microgel, an oil phase, a pH regulator, a thickening agent, a coloring agent and a water-alcohol phase; the mass percent of the Silsoft EAU microgel is 1-6%; the mass percent of the oil phase is 5-50%; the mass percent of the pH regulator is 0.2-1%; the mass percent of the thickening agent is 0.1-3%; the mass percent of the coloring agent is 0.2-15%; and the mass percent of the water-alcohol phase is 25-93.5%.
