Pimples are a result of pore closures on the skin due to the plugs made of oil and dirt. Itching might be a symptom of your skin being inflamed.

Hot showers damage by stripping natural oils away from the skin. So the­y're best avoided.

I get why you're worrie­d about stopping Skinshine cream after 4 ye­ars. Being careful about side e­ffects makes sense­. When you quit, your skin might get red, itchy, or dry.

Going slowly like­ this can let your skin adjust without too much trouble. Also, moisturize lots during this change­ to keep your skin healthy.
