You should always wash your face before waxing and perhaps that will prevent the small pimple outbreaks. The person doing the waxing should adhere to all hygienic standards as well so you avoid infection. To help boost healing, aloe vera gel and tea tree oil, red raspberry and azulene are good ingredients to consider.
A history should be taken to see what medications you are taking or to determine if there are any contraindications for waxing in your case. As for the ingrowns,I don't know how close to the surface they are. You may have to do gentle exfoliating over time to get them close enough to the surface to release them. If you have elecrologists where you live, you can have the electrologist lift them with a sterile lancet and them treat them so they never regrow again.
