Acne is caused by a bacterial infection which occurs when oil and dead skin cells clog the skin's pores. This condition is most likely to happen whenever there are hormonal changes or hormonal surges in the body - in other words, during puberty or pregnancy. During pregnancy, these hormonal changes tend to encourage the extra production of natural oils which can clog the pores of the skin, causing acne during pregnancy.
If you are pregnant, or plan to become pregnant, you may find that acne will tend to flare up during the first trimester. The good news is that this condition usually clears up on its own after the first trimester. However, if it does not clear up on its own, or if you want to get rid of pregnancy acne entirely, there are certain treatments available.
First, there is preventive action, consisting of cleanliness and a healthy lifestyle. This includes drinking plenty of water to keep your skin hydrated, eating plenty of fruits and vegetables which contain anti-inflammatory agents such as citric acid, and washing twice daily with a gentle, oil-free facial cleanser. This regimen controls or clears the production of skin oils and discourages pregnancy acne.
If acne flares up or persists, AVOID AT ALL COSTS taking any internal medication that contains the ingredient isotretenoin, such as Accutane. This can cause birth defects or genetic damage to the fetus. Instead, you should consult your dermatologist or obstetrician. It is generally accepted that the best oral acne treatment during pregnancy is to take oral erythromycin, provided it is prescribed by your doctor.
The best topical acne treatment during pregnancy would be any medication that contains benzoyl peroxide, as this is generally considered safe for the fetus. Avoid any treatment that contains salicylic acid, such as Stridex or Propa pH. However, even with topical treatments (treatments that are applied directly to the affected area), you are strongly advised to see your doctor. Topical treatments can enter your bloodstream and affect your fetus.
