Depends: Bp's function is to kill bacteria, dry & exfoliate the skin--so some irritation & reddness can be expected--it comes in 2 concentrations over the counter: 5% & 10% (5 harder to find, can "thin" w/skin lotion). If that solves it--then not allergy. If really itchy / any hives, reddness spreads beyond just where applied--could be allergic.

Avoid: Benzoyl peroxide is used primarily as a skin astringent to treat acne. If your skin reacts - and it may be allergic or irritant - use something else. There are many alternative products on the market.

Natural healing: The good news is that area has fantastic blood supply and so healing will occur rapidly. Inflammation (red, hot, tender swelling) is the body increasing the blood flow to the injury to bring healing factors to the area and also the veins expand to carry bad stuff away. Antibiotics are of no value there. Avoid further trauma to the area and let nature take it's course.
