Acne can present with various symptoms, such as:   ● Pimples - Pimples are one of the most recognizable signs of acne. They usually appear as small, raised bumps on the skin, often with a red or inflamed base. Pimples can be tender or painful to touch. ● Blackheads and whiteheads - These are non-inflammatory types of acne. Blackheads appear as small, dark spots on the skin's surface, while whiteheads are closed comedones that appear as small, flesh-colored bumps. Both blackheads and whiteheads are caused by clogged hair follicles and excess sebum production. ● Inflammation and redness - Acne can cause inflammation and redness in the affected areas. Inflammatory acne types include pustules, papules, nodules, and cysts.
