Sama seperti whitehead, jerawat cetek ini terbentuk di bibir, dagu dan lubang hidung apabila pori tersumbat. Papula ini adalah liang yang mengandungi sebum dan serpihan keratin. Setiap liang mempunyai kelenjar sebum yang boleh dikosongkan. Sebaik sahaja sebum bercampur dengan sel kulit mati dan serpihan keratin atau protein daripada epidermis, ia menghasilkan tombol yang menyerupai bintik putih. Orang yang mempunyai kulit berminyak cenderung mempunyai lebih banyak jerawat ini kerana lebih banyak sebum terkumpul di dalam pori-pori.
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.
