Menm jan ak whiteheads, bouton supèrfisyèl sa yo fòme sou bouch yo, manton ak twou nen yo lè porositë yo vin bouche. Papul sa yo se porositë ki gen sebase ak ti moso keratin. Chak pò gen yon glann sebase ki ka vide. Yon fwa sebase melanje ak selil po mouri ak fragman keratin oswa pwoteyin ki soti nan epidèm la, li pwodui bouton ki sanble ak whiteheads. Moun ki gen po lwil yo gen tandans gen plis nan bouton sa yo paske plis sebase akimile nan porositë yo.
These baby whiteheads are more superficial than traditional whiteheads and often spread through wrinkles in the skin. These are common around the nostrils and in the chin folds as it is where oil is collected and placed throughout the day. Creases can also cause friction, and anything that causes skin friction can cause acne because the pores are irritated. That said, no matter how often you try to pop these pimples, they're likely to change depending on their location. Sometimes we just have pore problems and can flare up in the same area over and over again.
