The Mask Is Occupational. The Jawline Acne Is Physics.

Hospital, mine, security and retail shifts keep fabric on the same skin for twelve hours. Friction plus heat is maskne — not a hygiene sermon.

Key takeaways

• Maskne is acne mechanica plus humidity under PPE, not a cleanliness failure.
• Stop stacking scrubs and acids on an already rubbed jawline.
• One leave-on (adapalene or azelaic acid) plus bland cream and exposed-skin SPF is the roster protocol.
• PIH on melanin-rich skin outlasts the bump — do not pick the strap line.
