When is acne worth seeing a doctor about?

Drafted with AI assistance · not reviewed by a dermatologist · Published August 2, 2026 · Last updated October 5, 2026

Short answer

See a doctor if self-treatment has not helped, if spots are deep, painful or scarring, if the skin looks infected, or if acne is affecting your mood [1][2]. Going early is reasonable: untreated severe acne can scar [2], and prescription treatments are much stronger than what you can buy [1].

Health services give a consistent list. The NHS advises seeing a doctor if you have tried treating acne yourself and it is not improving, if you have lots of spots or spots that are deep, painful or causing scars, if the skin shows signs of infection, or if acne is affecting your mental health [1]. MedlinePlus adds acne that is getting worse, acne with a lot of redness or cysts, scars appearing as acne clears, and self-care and over-the-counter medicine that have not helped after several months [2].

The table brings the two lists together. Meeting any one of these is enough of a reason to book.

Reason to book an appointmentWhat the guidance says
Self-care has not workedYou have tried treating it yourself and it is not getting better[1], or over-the-counter medicine has not helped after several months[2]
Deep, painful or many spotsLots of spots, or spots that are deep or painful[1]; a lot of redness around pimples, or cysts[2]
ScarringSpots causing scars[1], or scars appearing as acne clears[2]
Getting worseAcne that is getting worse[2]
Signs of infectionHot, swollen, red skin; redness can be harder to see on brown and black skin[1]
Your moodAcne affecting your mental health or causing emotional stress[1][2]

Why it is worth not waiting

Scarring is the main reason. Scarring may occur if severe acne is not treated [2], and a review in The Lancet notes that facial scarring from acne affects up to 20 percent of teenagers [6]. NIAMS lists preventing scarring among the main goals of treatment [4].

Mood is the other. Acne can cause anxiety, depression and low self-esteem [1], and MedlinePlus notes that some people become very depressed if acne is not treated [2]. NIAMS encourages people who feel embarrassed, shy or anxious because of acne to talk to their doctor about it [4]. Asking for help early is not an overreaction.

Who to see

You do not need to start with a specialist. Acne is diagnosed and treated by dermatologists, who specialize in skin, hair and nails, and also by primary care providers, including family doctors, internists and pediatricians [4]. A primary care doctor can prescribe treatment or refer you to a dermatologist [1].

What happens at the appointment

A doctor will usually diagnose acne by looking at your skin; tests are not needed in most cases [2]. They may ask about your family history, how long you have had acne, which medicines you take or have recently stopped, and, for girls and women, about menstrual cycles; sometimes they order blood tests to check whether another condition is causing the acne [4].

It helps to bring a list of what you have already tried and for how long, since many treatments take weeks to work [2].

What a doctor can offer

Prescription treatments are stronger than products from pharmacies and shops, and can be very effective for more severe acne [1]. They include topical retinoids such as tretinoin and tazarotene, topical antibiotics such as clindamycin, prescription-strength benzoyl peroxide, azelaic acid, and oral antibiotics such as doxycycline [2].

For women whose acne is driven by hormones, spironolactone or birth control pills may help [2]. The American Academy of Dermatology's 2024 guideline strongly recommends oral isotretinoin for acne that is severe, causing scarring or psychological distress, or not responding to other treatment [5]. Isotretinoin is closely supervised: it causes severe birth defects, so it must not be taken in pregnancy, and patients in the US enroll in a monitoring program called iPLEDGE and have regular blood tests [2].

For teenagers and parents

Acne is most common in teenagers and young adults, and in the teenage years it is more common in boys [3]. Pediatricians and family doctors treat it routinely [4], so a teenager does not need a referral to start.

The same signs apply at any age: deep, painful or scarring spots, acne that is getting worse, or acne that is getting a teenager down [1][2]. For a baby with acne, MedlinePlus advises contacting the baby's provider if it has not cleared on its own within three months [2].

While you wait for the appointment

Keep doing the basics. Clean the skin gently with a mild cleanser, avoid scrubbing, and avoid squeezing or picking, which can cause infection, slower healing and scarring [2]. Do not stop or switch medicines you have been prescribed without asking, and bring any questions about side effects to the visit [4].

Do not rely on the sun to fix it. MedlinePlus notes that a little sun may improve acne slightly but that tanning mostly hides it, and that too much sun or ultraviolet light raises the risk of wrinkles and skin cancer [2]; many acne medicines also make the skin burn more easily [4].
