Adult acne along the jawline and chin often has a hormonal driver. Medical Director Dr Sin Yong reads the pattern, checks whether a wider medical review is needed, then builds a plan at our Orchard Road clinic.
WhatsApp to Enquire →Key facts ↓Hormonal acne is adult acne driven largely by how the oil glands respond to androgens: deep, tender spots on the jawline, chin and neck that often flare before a period. It is treated medically first, sometimes with prescription medicines, with extractions, Hydrafacial and laser added for inflammation and marks. Irregular periods or excess hair warrant a check for PCOS.
Acne that starts or continues after the mid-twenties behaves differently from teenage acne. In women it tends to sit in a U-shape along the jawline, chin and upper neck, with fewer blackheads and more deep, sore lumps that take weeks to settle. Many people notice a monthly rhythm, with a crop of new spots in the days before a period.
The word “hormonal” rarely means the hormones themselves are abnormal. More often the oil glands in that area are unusually sensitive to normal androgen levels, producing more and thicker sebum. Other factors stack on top: friction from masks, phones and chin-resting, heavy or occlusive skincare, poor sleep, stress, and some supplements such as whey protein or bodybuilding products.
Men get adult acne too, and the same principles apply. The general mechanism of acne and how it is graded is covered on our acne treatment page; this page deals with the adult, lower-face pattern and what changes the plan.
Polycystic ovary syndrome (PCOS) is common and is one cause of persistent adult acne. The signs that suggest it are irregular or missed periods, new coarse hair on the chin, upper lip or abdomen, thinning hair on the scalp, difficulty with weight, and darker velvety skin on the neck or underarms (see dark underarms). International guidelines diagnose PCOS from a combination of cycle pattern, signs or blood markers of excess androgen, and ovarian findings, so testing is arranged by your GP or gynaecologist.
Some situations need prompt review rather than a skin plan: acne that appears suddenly and severely in adulthood, especially with a deepening voice or rapid hair growth; acne that started with a new medicine; and acne in someone who is pregnant or planning pregnancy, because several acne treatments are not used then (see pregnancy and breastfeeding safety). Dr Sin Yong writes a referral letter when one is needed.
“Jawline acne that follows your cycle is not a cleansing problem. I treat the gland that is reacting, and check whether something else is driving it.”
Medical base. A topical retinoid and an antimicrobial agent form the usual foundation. Where acne is persistent or scarring, prescription medicines are considered: hormonal contraception chosen with your gynaecologist, spironolactone (a prescription medicine that blocks androgen effects on the gland, not used in men or in pregnancy), or isotretinoin for nodular or scarring acne, with blood monitoring. Timing of procedures around isotretinoin is explained on isotretinoin and procedures.
In-clinic care. Hydrafacial uses a salicylic and glycolic acid step and vacuum extraction to clear congestion without hand squeezing. Ripe whiteheads may be released by the doctor; deep, tender nodules are not squeezed, because that drives inflammation further into the skin.
Light-based support. R2 Glow and Shaonu Guang (少女光) are used for inflammation and redness alongside medical care, not instead of it. Once breakouts are controlled, brown marks left behind can be addressed with T2 Frax Radiance on DEKA TORO, and textural scars on the acne scar pathway.
Most of the plan is creams and tablets, which do not hurt, although retinoids can sting and dry the skin for the first few weeks. Hydrafacial feels like cool suction with a light tingle during the acid step. Doctor-performed extraction gives a brief pressure and sting at each spot.
The lasers feel like warm snapping or flicking on the skin; contact cooling is built into the 675 nm treatment, and numbing cream can be applied beforehand if your skin is sensitive. Inflamed nodules are tender to touch, so they are treated around rather than pressed.
Day 0. Assessment, standard photographs and a written plan. An in-clinic session such as Hydrafacial or laser may be done the same day if the skin is ready.
Days 1–3. Mild redness after extraction or laser, settling within a day or two for most people. Any new topical may cause dryness or tightness; a bland moisturiser and sunscreen are used.
Week 1. Treated spots flatten. New spots can still appear, because medicines take weeks to change how the gland behaves.
Weeks 2–4. The retinoid adjustment phase; some people have a brief flare before it improves. In-clinic sessions are usually spaced two to four weeks apart.
Review at about 12 weeks. This is the earliest fair point to judge a medical plan. Doses, medicines and in-clinic steps are adjusted to what the skin shows.
The mechanism is the same: blocked follicles, excess oil, bacteria and inflammation. Hormonal acne describes an adult pattern where androgen-sensitive oil glands on the jawline, chin and neck dominate, often with a premenstrual flare and deeper, slower spots. That pattern changes which medicines are considered and whether a wider medical review is worthwhile.
Not always. Many people with jawline acne have normal hormone levels. Tests are worthwhile when there are irregular periods, excess hair growth, scalp thinning, sudden severe acne or other signs of PCOS. Dr Sin Yong will tell you if a GP or gynaecology review is advisable and provide a referral letter.
Some combined hormonal contraceptives reduce androgen effects on the oil gland and can help acne, while some progestin-only methods can make it worse. Contraception is a medical decision with its own risks, so the choice is made with your GP or gynaecologist, taking your health history into account.
Gentle extraction of blackheads and ripe whiteheads by a doctor, or vacuum extraction during Hydrafacial, is reasonable. Deep, painful nodules should not be squeezed, at home or in clinic, because pressure pushes inflammation deeper and raises the chance of marks and scarring.
Topical and oral medicines usually need eight to twelve weeks before a fair judgement can be made, and some people flare briefly in the first month. In-clinic treatments can calm active inflammation sooner, but the plan is reviewed at about three months rather than after one session.
It depends on what the plan contains: consultation, any prescription medicines and their monitoring, and the number and type of in-clinic sessions such as Hydrafacial or laser. Because plans differ from person to person, IN Eternity Clinic explains the full plan and its cost at consultation before anything starts.
