Hormone replacement therapy (HRT) can potentially worsen acne in some individuals. The effects vary depending on the specific type of HRT, the dosage, and individual factors.
Key points:
- Estrogen levels strongly influence acne, especially in those with a history of acne. Both high and low estrogen can trigger breakouts.
- Androgens like testosterone also play a role in acne. HRT regimens that increase testosterone could worsen acne.
- Progesterone may contribute to acne in those prone to breakouts.
- Individual factors like genetics, age, and skin type also affect acne risk on HRT.
- Working with an experienced hormone specialist can help minimize acne from HRT. Careful hormone monitoring and adjustments of regimens can often control acne.
Estrogen's Effects on Acne
- Estrogen suppresses sebum production and inflammation involved in acne. Fluctuating estrogen levels during the menstrual cycle, puberty, and menopause can trigger acne.
- Both high and low estrogen states may worsen acne:
- Low estrogen (e.g. during menopause) removes this protective effect, allowing more inflammation and sebum production.
- High estrogen (e.g. during pregnancy) conversely boosts sebum production which can clog pores.
- Any HRT regimen that causes significant estrogen fluctuations may provoke acne. This includes cyclic, short-acting, or inconsistent estrogen therapy.
Androgens and Acne
- Androgens like testosterone and DHT stimulate sebum production and skin cell growth, promoting acne.
- HRT regimens containing androgenic prohormones like DHEA may worsen acne, especially at higher doses.
- Anti-androgen therapy alongside estrogen is sometimes used to combat acne.
Progesterone and Acne
- Progesterone increases sebum secretion, which can contribute to clogged pores and acne ‒ especially in acne-prone individuals.
- Some report breakouts from progesterone-containing HRT regimens (both bioidentical and synthetic). For some, natural progesterone worsens acne more than synthetic progestins.
Individual Factors
- Those with a history of adult acne or hormonal breakouts may be most susceptible.
- Younger individuals are more prone as sebum production declines with age.
- Oily skin types see more acne exacerbation from hormonal shifts.
Strategies to Minimize Acne from HRT
- Start with low HRT doses and ramp up slowly while monitoring for acne.
- Choose transdermal estrogen when possible, as pills can cause more rapid spikes.
- Try a different progestogen if breakouts develop ‒ or use the lowest effective dose.
- Consistent, steady hormone levels are best to prevent acne. Avoid fluctuating regimens if possible.
- Combine HRT with acne medications like retinoids if needed. Most acne treatments are still compatible with HRT regimens.
- Work closely with an experienced hormone specialist. Through careful monitoring and adjustments, breakouts can often be controlled.
