Which grade of acne is considered severe and often develops from untreated grade 2 acne?

Grade 3 acne is indeed considered severe and is characterized by deep, inflamed, and painful lesions that can involve cysts and nodules. It often arises from the progression of untreated grade 2 acne, which includes moderate acne conditions like papules and pustules. If grade 2 acne is left unmanaged, it can escalate into grade 3 due to factors like clogged pores, inflammation, and the increased risk of secondary bacterial infections, leading to a more severe presentation.

This progression highlights the importance of early intervention and appropriate skin care to prevent the advancement of acne severity. Knowing the stages of acne helps estheticians assess and recommend treatments effectively to their clients, ensuring better skin health outcomes.
