Acne in pregnancy is very common, whether you have previously had acne or not. It is most common in the first three months while the levels of hormones are increasing. Progesterone is more androgenic (male hormone-like) than oestrogen and causes the secretions of your skin glands to increase, which can lead to more acne.
After the first trimester, progesterone is produced by the placenta and not the ovaries, so acne usually clears up after this time.
If you are planning to get pregnant, it is important to discuss your acne treatments with your doctor. Many of these can harm the unborn baby. These include tetracycline antibiotics, oral isotretinoin (Roaccutane, Accutane) and topical retinoids (tretinoin, isotretinoin and adapalene). Tetracycline tablets can damage the bones and teeth of the developing foetus.
Isotretinoin tablets can cause severe abnormalities and topical retinoids can be absorbed into the bloodstream and have the same damaging effect.
Erythromycin is the only antibiotic regarded as being safe in pregnancy, but it may not be very effective as many skin bacteria are now resistant to it. However, it's probably bettter to avoid all medications if possible.
While pregnant, the skin can also dry out more than normal so drying treatments such as benzoyl peroxide cream or gel may be too harsh. It's better to use products that are natural in origin. Tea tree oil is safe to use on spots and blemishes.
An every day facial wash, such as the essential facial wash or peppermint facial wash is mild enough to be used on skin during pregnancy. If you have blackheads and oily skin, clay masks are fantastic for absorbing oils and blocked pores - try bentonite clay or the seaweed clay mask.
Remember to drink plenty of water and eat lots of fruit and vegetables - beneficial for your skin and the developing baby! If you're finding it hard to eat well because you have morning sickness, try freshly made smoothies and soups to get the fruit and vegetables into your diet easily.
