Chin acne is almost always hormonal — spironolactone at 50–100 mg daily plus nightly tretinoin is the dermatologist standard. The chin and jawline track androgen activity, which is why flares synchronize with the week before your period. For the individual spots, Rael Microcrystal, ZitSticka Killa, or Peace Out Acne microdart patches handle the early under-the-skin bumps with 2% salicylic acid and niacinamide; Rael Miracle Patch, Hero Mighty Patch, or COSRX cover the surfaced whiteheads in 6–12 hours. Stop touching your chin during work calls and swap pillowcases twice a week — both reduce mechanical and bacterial load. If flares come every cycle for three months, see a dermatologist; topicals alone rarely fix a hormonal pattern.
