Are there any ointments or cosmetics that can help manage acne to prevent scarring?

Even though I am an adult, I still often get acne or pimples around my mouth.

It hurts, and a scar forms after squeezing it out.

Are there any ointments or cosmetics that can help manage scarring?

It would be best to go to a dermatologist for care, but since that isn't always possible...

Please share any tips for managing acne scars.

Thank you
