Adult acne on the jawline: why it appears and what you can do
Many people who didn’t have acne as teenagers start getting pimples on their jawline and chin after age 25. It’s often linked to hormonal changes, stress, and friction (masks, phones, hands).

Where do you get the most breakouts?

Yes: the jawline and chin can coincide with breakouts influenced by hormonal fluctuations, but location alone can’t identify the cause. Stress, friction, and heavy products can also contribute; it’s not a lack of hygiene, and scrubbing more often tends to irritate the skin.
To start, I’d stick to a simple routine for several weeks: a gentle cleanser, moisturizer, and non-comedogenic sunscreen. If the pimples are mild, try just one active: salicylic acid (BHA) at a low concentration a few nights a week, or benzoyl peroxide at a low concentration as a spot treatment. Introducing both at once makes it harder to tell what’s causing irritation; benzoyl peroxide can also bleach fabrics. Stop using it if it causes significant irritation.
Regularly clean your phone and objects that rub against the area, and avoid picking at pimples. If they’re painful or deep, leave marks, appear suddenly along with other changes, or don’t improve after about 8–12 weeks, it’s a good idea to consult a dermatologist; you may need a prescription option. If you could be pregnant, ask before using actives such as retinoids.
Can makeup make jawline acne worse? What type of foundation is best?
Yes, it can make it worse if the foundation is heavy, irritates your skin, or builds up right in the area, although it isn’t always the cause. Look for a lightweight formula labeled “non-comedogenic”; “oil-free” can be a clue, but it doesn’t guarantee it won’t cause pimples. Liquid or powder foundations can work: how your skin responds matters more than the format. If you have sensitive skin, it’s better to choose a fragrance-free formula and avoid very full-coverage layers every day.
Try just one new foundation for a few weeks and watch the area. Gently remove it at the end of the day, clean your brushes regularly, and avoid applying makeup over open or irritated pimples. If the breakout is painful, deep, or leaves marks, it’s better to consult a dermatologist rather than trying to cover it with more layers.
