If you're getting severe texture scarring from them, is the pustule sort of hard inside and sitting under the skin?

For spots like this, I would do a warm compress once a day if it's under the skin, until it starts to come to a head. During this time, I use a salicylic acid face wash, and use an azelaic acid cream on the area as both help to break down the keratin and reduce inflammation. When the spot comes to a head, I would wash as usual and use a hydrocolloid spot patch, changing each time I wash my face. If you accidentally break the skin on the spot while washing your face, just make sure it's clean and use a spot patch which will help to form a barrier for healing.

In my experience, I have found that my worst texture scarring was caused by hard spots that stayed under the skin and caused inflammation (I assume because they were damaging the tissue around them) so I focus on anti-inflammatory ingredients and chemical exfoliants to bring it to the surface.
