Physical irritation and acne
Less irritation = less acne
Anything which rubs, scratches, or comes into prolonged contact with the skin can cause irritation and potentially contribute to breakouts. It is helpful to become aware of how you can remain gentle to your skin during your acne-prone years. None of us can completely avoid irritation. However, becoming aware of sources of irritation, and reducing them when you can, will help you achieve and maintain clear skin.
If you experience excess irritation in any area, be sure to carefully perform The Regimen in that area, using plenty of benzoyl peroxide, and consider applying AHA as well. This combo can often effectively combat intermittent irritation.
