# AAD — What causes acne?

## Quick Summary

AAD patient guidance explaining acne causes, follicle and oil context, and why acne is usually multi-factorial rather than caused by one bedding or hygiene habit alone.

## What Studied

Patient-facing dermatology guidance on acne causes.

## Main Findings

The page supports a multi-factor view of acne, which helps keep pillowcase residue and friction in context as possible contributors rather than sole causes.

## Why It Matters

It anchors the myth-check: changing pillowcases can be a useful low-risk experiment, but persistent or severe acne needs broader acne guidance.
