Pregnancy skin changes

Although skin changes in pregnancy may be a cause of concern for the expectant mum, most are perfectly normal physiological responses, dermatology expert Julie Van Onselen offers reassuring advice on some common ones.

Pregnancy causes a variety of skin changes, which, in the majority of cases, are a normal physiological response. Existing inflammatory skin conditions, such as eczema and psoriasis, can also change in pregnancy, sometimes improving and sometimes deteriorating.

Any healthcare professional seeing a mother during her pregnancy needs to provide her with an explanation of visible skin changes during pregnancy to offer reassurance and suggest measures to improve skin comfort.

It is also important for the health professional to know which skin changes are normal physiological changes and which may be a dermatosis specific to pregnancy. Normal skin changes in pregnancy can be divided into five categories:

  Skin care advice Cautions
Pigmentary changes Melasma: Use sun protection (SPF30) and a sun
hat, as sun exposure will increase melasma. 

Check changing and new moles in

pregnancy. Refer to a dermatologist if

changes are suspicious.

Vascular changes

Palmar erythema: moisturise palms with a

medical emollient, keep cream in fridge so it
is cooling.

Gingivitis: diligent oral hygiene, antiseptic

mouth washes after eating and local

anaesethic mouth gels for ulcers.

Varicose veins: support stockings and

elevate legs when resting.

Haemorrhoids: high fibre diet, lactulose, avoid

straining and non-steroidal rectal cream 

Calf pain should be immediately

investigated as DVT may occur in

pregnancy.

Hair and nail changes

Increased facial hair: can be removed with

facial depilatory creams and electrolysis.

Investigate and refer women with

hirsutism and acne, developing in second

trimester.

Sweat and sebaceous gland changes

Increased sweat gland activity: keep cool

and try not to overheat.

 

Connective tissue disruption

Stretch marks: can’t be prevented as they

originate in connective tissue; reassure that

they will eventually fade to white

 

 

Changes with existing inflammatory skin conditions

Pregnancy can improve some inflammatory skin conditions but others are unpredictable. Atopic eczema is very variable in pregnancy; in the post natal period, nipple and hand eczema are often exacerbated. Psoriasis often improves in pregnancy but will generally relapse in the post partum period.

Women with systemic lupus ertythematous generally cope well with pregnancy but a few may develop renal problems. Cutaneous lupus does not appear to be affected by pregnancy. Women with scleroderma can often improve, but again renal deterioration with pre-eclampsia and hypertension is a risk of pregnancy.

The health professional has an important role in the provision of skin care in pregnancy. The skin changes discussed in this article are generally normal physiological responses. However, many women will still become anxious about them, and for some they may cause added discomfort in pregnancy. The healthcare professional can provide invaluable support by providing reassurance and skin care advice as well as being aware when a skin change requires further investigation.
