What are whiteheads and how do they form?
The NHS describes whiteheads as small skin-coloured bumps with white pus NHS acne guide. They differ from flat black-brown blackheads, raised red papules, pus-filled pustules, and deeper painful nodules and cysts.
NIAMS explains that acne develops when hair, sebum oil, and keratinocyte skin cells stick together inside the pore. The mix traps oil and cells and lets ordinary skin bacteria grow.
Should you squeeze or scrub them?
Leave whiteheads alone. The NHS advises people with acne not to pick, squeeze, or scrub spots and to avoid very hot or cold water.
Squeezing worsens acne and risks permanent scarring. NIAMS notes early treatment is the best way to prevent scars for adolescents and adults.
- Do not pick or squeeze spots
- Do not scrub skin harshly
- Avoid very hot or cold water
