Acne and Hormones
Acne is one of the most common skin conditions, and hormones play a recognised part in why it develops. Most acne is not a sign of any hormone disorder, but in some situations the pattern prompts a clinician to look further. This page explains the possible links and why an assessment matters more than self-diagnosis.
How acne can relate to hormones
Acne forms when the skin's oil glands produce more oil and pores become blocked, allowing inflammation and spots to develop. Androgens, a group of hormones present in everyone, stimulate these oil glands, which is part of why acne is so common during puberty when androgen activity rises. Normal cyclical changes in hormones can also influence breakouts. This is established physiology, and it does not mean that most people with acne have abnormal hormone levels.
Because acne is so common and usually unrelated to any underlying disorder, it is best understood as a clue rather than a diagnosis on its own. The wider pattern of symptoms is what helps a clinician decide whether anything more is going on.
Which hormones and conditions may be involved
Most acne does not need hormone testing. When the picture suggests it, a clinician may consider:
- Androgens. Higher androgen activity can drive oilier skin and acne, particularly when acne appears with other features such as excess hair growth or irregular periods.
- PCOS. Polycystic ovary syndrome can include acne alongside irregular periods and other features.
- Other endocrine conditions. Less commonly, conditions affecting cortisol or other hormones can affect the skin.
Blood tests a clinician might consider
Routine acne usually does not need blood tests. When the pattern points to a possible hormonal cause, a clinician might consider:
- Androgen-related tests, interpreted alongside the wider picture.
- Tests relevant to PCOS when irregular periods or other features are present.
- Other endocrine tests only if specific signs suggest them.

Non-hormonal causes to keep in mind
Acne is influenced by many factors beyond hormones, including genetics, the natural bacteria on the skin, some skin and hair products, friction, and certain medicines. It is a normal, treatable skin condition for most people and does not by itself indicate a hormone disorder. Because everyday factors are so common, a clinician usually focuses first on the skin itself.
When to see a clinician
It is reasonable to seek advice when acne is persistent, severe, scarring, or distressing, or when it appears with other features such as irregular periods, excess hair growth, or a sudden change. A clinician, often a doctor or dermatologist, can assess the skin, discuss treatment options, and decide whether any hormone testing is warranted. This is far more reliable than testing yourself, because results only make sense in context. This page is educational and is not a substitute for personalised medical advice.
Frequently asked questions
Does acne mean my hormones are unbalanced?
Usually not. Hormones play a normal part in acne, but most people with acne have normal hormone levels. It is generally a common skin condition rather than a sign of a disorder.
When would a clinician check hormones for acne?
Often when acne appears with other features such as irregular periods, excess hair growth, or a sudden change. In those cases conditions like PCOS may be considered.
Should I order my own hormone tests for acne?
Tests are most useful when chosen and interpreted in context. Ordering them in isolation often leads to confusion, so speaking with a clinician first is generally more helpful.
Can acne be treated even if hormones are normal?
Yes. Most acne is managed as a skin condition regardless of hormone levels. A clinician or dermatologist can discuss the options suited to your situation.
