Second trimester acne breakouts happen when rising androgens increase skin oil and clog pores. They commonly emerge during the first two trimesters on the face, chest, or back.
Androgens are male-type hormones that rise in pregnancy. Sebum is the oily, waxy substance that can trap dead cells and block follicles. That blockage can form blackheads, pimples, pustules, or cysts.

Why does acne change in the second trimester?
Acne often improves in the first trimester but may worsen later. A Johns Hopkins–University of Michigan review reports that maternal androgen concentrations rise and increase sebum production, with pregnancy immune changes also contributing, as described in the family medicine review.
That timing matters for expectations. Early clearing does not guarantee clear skin for the whole pregnancy. New or returning breakouts in mid-pregnancy can still reflect normal hormonal shifts.
What is happening inside the pore?
Rising androgens enlarge skin glands and raise sebum output. Cleveland Clinic explains that excess sebum blocks pores and leads to blackheads, pimples, pustules, or cysts in its hormonal acne overview.
The trapped oil mixes with dead cells inside the follicle. That plug promotes bacteria and inflammation. The result is redness, swelling, tenderness, or deeper bumps.
Who tends to get pregnancy breakouts?
Anyone pregnant can develop hormonal or pregnancy acne. Breakouts may affect the face, chest, or back.
Risk is higher after premenstrual breakouts. UT Southwestern Medical Center notes that people who broke out before menstrual periods are more likely to experience pregnancy acne in its pregnancy acne guide.
Which treatments can you discuss with your provider?
ACOG guidance summarized by MotherToBaby says topical benzoyl peroxide, azelaic acid, salicylic acid, or glycolic acid may be used during pregnancy if needed after talking with a provider. Bring your full product list to the visit, including cleansers, spot treatments, and anti-aging creams.
Avoid oral isotretinoin in pregnancy because it can cause birth defects. Also avoid topical retinoids during pregnancy and check labels because they are available with and without a prescription.
