Rashes come in different sizes, colors, and textures. Environmental factors may cause some rashes. So, for example, if you recently relocated to a new location, your skin will react in a certain way, and you may need some time to adapt to that environment fully. However, some rashes, such as those beaten by an insect, may require emergency medical treatment. If you have a rash and notice any of the following symptoms, you should see a doctor immediately:

Chemical peeling is a procedure that entails the elimination of dead skin cells and the outermost layer of your skin. Chemical peels work as exfoliators and come in three types – superficial, medium, and deep.
