What should you know about razor bump marks?

A bump may settle while pigment remains behind, especially after rubbing, scratching, or picking. Flat brown or grey areas are usually colour change rather than active infection; pink or red areas can reflect ongoing inflammation. Raised, firm, or tender spots may still contain an ingrown hair or represent folliculitis. Similar rough dots on the upper arms or thighs can have another cause, such as keratosis pilaris. Razor bumps are also called pseudofolliculitis barbae, particularly when curved hairs grow back into shaved skin.

Pause close shaving over irritated skin and avoid squeezing or digging for a trapped hair. Wash gently, pat dry, and use a bland moisturiser to reduce friction. Loose clothing can help on body areas that rub. When the skin has calmed, shave in the direction of growth with a clean, sharp tool, light pressure, and a lubricating product; avoid repeated passes. A clinician can discuss pigment care or [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) when repeated hair removal keeps triggering bumps.

Arrange a medical assessment if marks are spreading, hot, increasingly painful, draining pus, or accompanied by fever. Seek advice for a lump that stays raised, bleeds, changes quickly, or does not improve after you stop irritating it. A clinician can distinguish a lingering mark from active [Folliculitis](/conditions/folliculitis/) or an [Ingrown Hairs](/symptoms/ingrown-hairs/) problem.

Ask whether the area is pigment change, an active follicle problem, or scarring; which hair-removal method suits your skin; and whether treatment should wait until inflammation has settled.
