Adult pimples? Adult acne? It's stressful.

I'm not really sure about the difference between pimples and acne, but anyway, since I keep getting breakouts on my face even after becoming an adult, I get stressed periodically.

As shown in the picture, they can appear small without inflammation, or they can grow large and painful like purulent or inflammatory acne.

Pustular or inflammatory acne is especially stressful.

It is the most painful, but it always leaves marks on the face like pigmentation after it bursts.

I really thought this wouldn't happen after I passed my teens, but I didn't know it would continue like this even after becoming an adult at such an old age.

When it gets really severe, I go to Maypure and get acne inflammation injections, but is there a way to fundamentally prevent them from appearing?
