Nodular acne is characterized by hard, painful lumps beneath the skinโs surface. These nodules are larger and more severe than typical pimples and are less likely to come to a head. Causes include hormonal fluctuations, genetics, and lifestyle factors. Treatment often involves prescription medications, such as oral antibiotics and retinoids, and sometimes isotretinoin for more severe cases. Maintaining a consistent skincare routine and avoiding pore-clogging products can help manage and prevent nodular acne.
