Acne, also referred to as acne vulgaris, occurs when pores become blocked with excess oil, dirt, dead skin cells, or bacteria. This blockage can sometimes lead to inflammation. Although acne is most prevalent among teenagers and young adults, older age groups may also experience it. The condition can present itself in various forms, including:

• Small, tender, red bumps called papules
• Pustules or pimples with pus-filled tips
• Whiteheads or blackheads, which are closed or open clogged pores
• Large nodules
• Cystic acne

The causes of acne can be diverse, ranging from hormonal changes, genetic factors, and stress to dietary habits or side effects from certain medications.
