Can Emergency Contraception Cause Acne?

Emergency contraception—commonly known as the “morning-after pill”—is a safe and effective option for preventing pregnancy after unprotected intercourse or contraceptive failure. However, some individuals report new-onset or worsening acne following its use. While anecdotal reports exist, current clinical evidence does not support a direct causal link between emergency contraceptive pills (ECPs) and acne development.

Most ECPs available globally contain either levonorgestrel (a synthetic progestin) or ulipristal acetate (a selective progesterone receptor modulator). Unlike combined oral contraceptives—which contain both estrogen and progestin and can influence sebum production via hormonal modulation—ECPs deliver a single, high-dose pulse of hormone activity that is brief and transient. This short-term exposure is insufficient to trigger lasting changes in sebaceous gland function or androgen-sensitive skin responses.

That said, hormonal fluctuations—even brief ones—can temporarily affect individual skin physiology. Some people may experience transient acne flares coinciding with ECP use, but these are more likely attributable to baseline hormonal variability, stress related to the event prompting ECP use, or concurrent factors such as diet, sleep disruption, or preexisting acne-prone skin. Importantly, no large-scale clinical trials or systematic reviews have identified acne as a statistically significant adverse effect of levonorgestrel- or ulipristal-based emergency contraception.

If acne persists or worsens significantly after ECP use, clinicians recommend evaluating for other contributing factors—including polycystic ovary syndrome (PCOS), underlying endocrine imbalances, or medication interactions—and considering dermatologic consultation. For individuals concerned about hormonal effects on skin, long-term contraceptive options with documented anti-acne benefits—such as certain combined oral contraceptives containing drospirenone or norgestimate—may be appropriate for ongoing management, subject to medical evaluation and shared decision-making.
