The Most Common Causes of Acne
Exercise

Though it may be surprising to some individuals, hitting the gym or participating in sports can contribute to acne breakouts. This can be due to bacteria as well as oil and sweat. For this reason, individuals should clean gym equipment and things like helmets after using them, or even before if they are unsure if the last person using it cleaned it. It is also important to have a change of clothes when exercising, as swearing sweaty clothing can cause body acne. As mentioned previously, showering right after exercising and putting on a clean set of clothes will help avoid acne, as well as regularly washing things like uniforms and sports gear.
Topical Agents

Topical agents are medications applied directly to the skin to provide relief for a medical ailment. Because they typically come in the form of a lotion or gel, they can cause acne. However, because everyone is different, and therefore everyone will have different reactions and experiences with topical agents, some individuals can use topical lotions on their face and not undergo a single blemish, while others who have sensitive skin will end up with acne breakouts quickly.
If someone is not able to pinpoint the cause of their acne, some topical agents might be the cause and they should look over their formulations. In cases like this, product shifts can help, as can using over-the-counter treatment for acne. Specifically, products with salicylic acid or benzoyl peroxide are great with fighting off pesky pimples. If these do not work, patients can always discuss their situation with a doctor and look at prescription treatments.
