The short explanation
Deep, painful bumps on the chin and jawline that flare before periods are a common pattern of hormonal acne. In the days before a period, hormone changes can make oil glands more active and the skin around pores more inflamed. When the blockage sits deep, it forms a tender lump rather than a whitehead, which is why it cannot be squeezed. Please avoid squeezing or pricking these lumps. Pressing pushes inflammation deeper, increases pain, and raises the risk of dark marks and scars, which are especially common on Indian skin. A cold compress may ease the pain for a while. Because deep cystic acne is the type most likely to scar, it is worth seeing a dermatologist rather than only trying over-the-counter products.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A dermatologist may suggest skin treatments, and sometimes medicines that act on hormones, depending on your age, periods, plans for pregnancy and how severe the acne is.
- If you also have irregular periods, extra facial hair or weight changes, your doctor may check for PCOS.
- Some women notice acne changes after stopping or starting the pill or other hormonal contraception. Mention this if it applies.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether your acne is hormonal or which treatment is right. A dermatologist needs to see your skin and know your history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this pattern likely to be hormonal acne?
- Should I be checked for PCOS?
- Which treatment options suit me, especially if I am planning a pregnancy?
- How can I prevent these from leaving marks?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a doctor within a few days if a lump becomes very swollen, hot and spreading, or you develop fever.
Raise it at a routine appointment
