These seem like inflammatory acne, you can use an ointment called Erytop N every night and see what happens.
Also, in these cases, it is good to have a skin care regimen planned out from a good face wash to all the creams and diet. Book a direct consultation as I work in that area and maybe try and help you out get rid of this permanently.
Health Tips
