Hormonal acne looks like other acne up close. It is the pattern — where the spots sit, how deep they go, and when they arrive — that names it.
Deep spots are red and swollen, and redness is harder to see on brown and Black skin. That means hormonal acne there is regularly judged as milder than it is, and treated less firmly than it should be. Pressing gently to check for tenderness tells you more than looking does. The other difference is what is left behind: on deeper skin each lump reliably leaves a dark mark that lasts six to twelve months, so the face can carry the record of a flare long after the flare is over. Getting the deep spots under control quickly matters more here than anywhere else.
Several things sit on the jawline and are not this. See Lookalikes near the bottom of this page.
Hormonal acne is not caused by having too much of a hormone. In almost everyone, the hormone levels are normal. What differs is how strongly the oil gland responds to them.
Androgens — testosterone and its relatives, which everybody makes — tell oil glands to grow and produce more oil. In some people those glands are unusually sensitive to a normal amount of androgen. They make more oil, the pore lining thickens, and the clog that forms sits deep, where it becomes an inflamed lump rather than a surface spot. Sensitivity is largely inherited, which is why this often runs in families.
The monthly pattern comes from the shift in the balance of hormones across the cycle. In the week before a period, oestrogen and progesterone fall while androgen activity stays steady, so the androgen effect is relatively stronger. Skin also swells slightly, which narrows pores. Coming off hormonal contraception can set the same thing off for several months. In a minority of people there is an underlying cause worth finding, most often polycystic ovary syndrome — but that is the exception, not the rule.
Over-the-counter products rarely clear this pattern on their own, but they are worth keeping in place underneath a prescription. Use them for the surface spots and the marks, not for the deep ones.
Over-the-counter treatment rarely settles this pattern on its own, so there is less reason to wait than with other acne. Book a visit if:
What the visit gets you: access to the treatments that actually target this pathway — spironolactone, the combined pill and Winlevi — none of which you can buy. You also get a decision on whether hormone testing is worth doing, a plan that runs over cycles rather than weeks, and treatment started before deep spots start scarring.
Hormonal acne is diagnosed on the pattern, by looking. Most people need no test, and a normal result does not change the diagnosis or rule out hormonal treatment.
Blood tests are worth doing when something points beyond ordinary hormonal acne: acne that appeared suddenly and severely, irregular or absent periods, new coarse hair growth on the face, chest or abdomen, or thinning hair on the scalp. That combination is mainly a search for polycystic ovary syndrome, and much less often for a problem with the adrenal glands.
The usual panel is total and free testosterone, DHEAS, and sometimes 17-hydroxyprogesterone, along with LH and FSH. Two practical details decide whether the result means anything. They are taken in the first week of the cycle, and they are unreliable while you are on hormonal contraception — the combined pill suppresses the hormones being measured, so a normal result on the pill tells you very little. Stopping contraception purely to test is not usually worth it unless the answer would change your treatment.
Some blood tests are about the medication rather than the diagnosis: potassium in some people starting spironolactone, and pregnancy testing where it is required before a prescription.
This is where the treatments that actually target hormonal acne live. The hormonal options are what separate this page from general acne treatment, and they are judged over months rather than weeks.
One thing, used for one situation: a deep, painful lump that needs to go down quickly.
Usually little visible change, and sometimes a flare partway through. This is the point most people quit, and quitting here is why so many people believe nothing works.
Deep spots start arriving less often and hurting less. Count the lumps in the week before your period and compare it to where you started — that number moves before the face looks different.
This is where hormonal treatment is fairly judged. Most people who respond are clearly better by here. If nothing has shifted by six months at a proper dose, it is reasonable to change course.
Spots stop before the marks fade. Brown and purple patches take three to twelve months of their own, longer on deeper skin. Clear skin with marks on it is a treatment working, not a treatment failing.
Spironolactone, the pill and Winlevi all control acne rather than cure it, and acne usually returns within a few months of stopping. Many people stay on treatment for years, then try coming off once the pattern has naturally quietened.
Hormonal acne is not dangerous. What it leaves behind is the reason to treat it early.
