Most people are mesmerized at the way their skin turn bright red as the seasons change and dermatologists offer a very simple yet real fact, they are forgetting the basics of skin care that says the skin reacts to the environment. Most people tend to have an astringent or two to cleanse their skin of excess oil that tends to be quite a real threat during the summer. As the weather shifts to colder weather, they continue with their skin care regimen forgetting the fact that skin is drier in the winter than in summer and using astringent dries it up more resulting in ever drier skin.
