October is the height of autumn and there are days when the temperature suddenly drops. Have you ever felt cold because you delayed changing your loungewear and bedding at home? This is also the time when your body and skin cannot keep up with the changes in the weather, causing poor circulation and a slowdown in metabolism, leading to various skin problems such as dullness, stiffness, roughness, and dryness.
In other words, October is a time when dryness and poor metabolism combine to weaken the skin and accelerate skin aging (wrinkles, lack of firmness, sagging, etc.). If the foundation of your skin is unstable, the beauty ingredients in your cosmetics will not be able to fully utilize their effects.
