Which grade of acne is red, inflamed, and has many comedones, papules, and pustules that should not be treated?

Grade 3 acne is characterized by significant inflammation, the presence of numerous comedones (clogged pores), papules (small raised bumps), and pustules (pus-filled lesions). This grade of acne indicates a moderate to severe level of skin irritation and can lead to scarring if not properly managed. Because of the extensive inflammation and the risk of complications, treatments for Grade 3 acne should be approached with caution; aggressive treatments are often not recommended at this stage without professional guidance. This highlights the importance of distinguishing between different grades of acne for appropriate treatment strategies. This knowledge is essential for providing safe and effective skin care treatments, especially in an esthetician practice setting.
