When to see a doctor
See a doctor urgently if:
- If you have signs of a serious skin infection (red streaks, fever, severe pain)
Book a routine appointment if:
- If acne is affecting your self-esteem or daily life
- If over-the-counter treatments have not worked after a few weeks
- If you have painful cysts or nodules
Diagnosis
A doctor or dermatologist can diagnose acne simply by looking at your skin.
Tests that may be done
- Usually no tests are needed.
- In some cases, a skin swab may be taken to check for bacteria if infection is suspected.
What to expect at your appointment
The doctor will ask about your skin care routine, medical history, and how long you have had acne. They may also ask about any medicines you take.
Treatment
Treatment depends on how severe your acne is. Options include self-care, prescription creams, and oral medicines. Your doctor will recommend the best plan for you.
Self-care at home
- Wash your face twice a day with a gentle cleanser
- Use oil-free, 'non-comedogenic' (won’t clog pores) products
- Avoid picking or squeezing spots, as this can cause scars
- Be gentle – scrubbing can make acne worse
Medical treatments
Doctors can prescribe topical creams, gels, or lotions that help unblock pores, reduce bacteria, or calm inflammation. For more severe acne, oral medicines that work throughout the body may be recommended. Always follow your doctor’s instructions and never share prescriptions.
When is surgery considered?
Surgery is rarely needed. For very large cysts or scars, a dermatologist may offer drainage or minor procedures, but this is not common.
Living with this condition
Acne can be managed with a consistent gentle skin care routine. It may take weeks to see improvement, so be patient.
Lifestyle tips
- Try to manage stress – stress can make acne worse
- Get enough sleep
- Avoid touching your face often
Diet and exercise
No specific diet is proven to cure acne, but eating a balanced diet and staying active supports overall skin health. Some people find that dairy or sugary foods affect their spots.
Mental health and emotional wellbeing
Acne can affect how you feel about your appearance and may lead to low self-esteem, anxiety, or depression. It is important to talk to someone if you feel upset.
Prevention
Acne cannot always be prevented, but gentle skin care and avoiding oily products can help reduce the chance of breakouts.
Complications
If left untreated
- Permanent scars or dark spots
- Emotional distress, low self-esteem, or anxiety
Long-term outlook
For most people, acne improves over time, especially with treatment. Even severe acne can be managed with medical help, and scars can be treated. You do not have to face it alone.
