I have acne/ spots predominantly under my chin which doesnt occur as much across the rest of my face. I have an oily (?) skin type and I use innisfree bija trouble cleansing foam + bija trouble toner twice a day. I dont have much of a routine beyond this and the products I use havent changed recently. The spots under my chin has been an ongoing thing for several years. Im not really sure what they are / why the acne is predominantly under the chin either. Any help is appreciated! Thank you!!
