Acne is a common skin condition characterized by the clogging of your pores with oil (sebum) and dead skin cells.

Acne can be non-inflammatory or inflammatory. Non-inflammatory acne refers to blackheads and whiteheads. Inflammatory acne is more severe and consists of papules, pustules, nodules, or pus-filled cysts. 

Acne usually occurs on the face but may appear on the chest and back as well. 

Although acne is rarely medically dangerous, it can cause discomfort and reduce self-esteem. Inflammatory acne, namely papules, pustules, nodules, and cysts, can even be painful. Seeking a dermatologist to treat your acne is highly recommended as improper treatment can lead to scarring.

More About Acne


Acne has 4 main causes:

  • Excessive sebum production
  • Clogged hair follicles 
  • Bacteria
  • Inflammation 

Other acne triggers include hormonal changes, certain steroids, skin irritants, and certain medical conditions. 

Who is at risk? 

Acne can affect anyone. Adolescents and young adults are the most susceptible as they are undergoing puberty-induced hormonal changes. 

What are the most effective treatments? 

Treatments vary depending on the acne’s type and severity. Over-the-counter salicylic acid and benzoyl peroxide and topical retinoids can fight off non-inflammatory acne. Topical or oral antimicrobials and isotretinoin should be reserved for acute inflammatory acne. 

Acne scars can be treated by laser resurfacing and micro-needling, among other methods.
