The 'pore filter' effect in a jar, and the reason a Korean primer can make your nose look airbrushed in about four seconds. These are tiny hard spheres that sit on the surface and bounce light in all directions. Nothing is being treated. Wash it off and the pores are exactly as they were.

What winter does to your skin

Cold air and indoor heating strip moisture, so layer hydrating toners and essences under a richer cream or occlusive.

How that changes Polymethylsilsesquioxane

Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. Polymethylsilsesquioxane works on pores & texture, rough & uneven texture, oil control, and it is normally applied AM.

What to layer it with
