Key points

Acne is a very common skin condition, particularly during the teenage years, though it can affect people at any age. It happens when hair follicles become blocked with oil and dead skin cells, leading to blackheads, whiteheads, pimples, and sometimes deeper, more painful cysts, most commonly on the face, chest, and back.

What is Acne?
Acne is a very common skin condition, particularly during the teenage years, though it can affect people at any age. It happens when hair follicles become blocked with oil and dead skin cells, leading to blackheads, whiteheads, pimples, and sometimes deeper, more painful cysts, most commonly on the face, chest, and back.
Acne is influenced by hormones, genetics, and sometimes stress, and while it often improves with time, effective treatments exist for all severities, from over-the-counter options to prescription treatments for more persistent or severe cases.
02 · Understand
Clinical context
Treatment often takes several weeks to show results
Most acne treatments take 6 to 8 weeks to show noticeable improvement, and sometimes longer — sticking with a treatment consistently, rather than switching too soon, tends to bring better results.

Practical steps
Avoid Picking or Squeezing Spots
Picking at acne can worsen inflammation, spread bacteria, and increase the risk of permanent scarring — however tempting, it tends to make things worse rather than better.
- 1Wash affected areas gently, twice daily.Use a mild, non-abrasive cleanser rather than harsh scrubbing, which can irritate the skin further.
- 2Try an over-the-counter treatment.Products containing benzoyl peroxide or salicylic acid are commonly recommended starting points.
- 3Avoid oil-based or heavy cosmetic products.Look for products labelled "non-comedogenic," which are less likely to block pores.
- 4Be patient and consistent.Most treatments take several weeks to show visible improvement.
- 5See a doctor for persistent or severe acne.Prescription options, including topical retinoids or oral medication, are available and effective for cases that don't respond to over-the-counter treatment.
