What Causes Dry Skin When Pregnant and How to Treat It

Dry skin, medically known as xerosis, is a common and often irritating symptom experienced by many individuals during pregnancy. This change in skin texture is typically a benign, temporary consequence of significant physiological changes occurring in the body. Understanding the underlying causes helps in selecting the right approach. It is also important to ensure that any products used are safe for pregnancy, as certain ingredients can be absorbed and should be avoided for use.

Why Pregnancy Causes Skin Dryness

The dramatic shifts in the internal environment during pregnancy are the primary drivers of skin changes. Hormonal fluctuations are a major cause, though they can have varied effects on different individuals. Surging levels of hormones like estrogen and progesterone, which are elevated throughout gestation, can alter the skin’s natural balance. While some experience increased oil production and a “pregnancy glow,” others may see a reduction in the skin’s natural oil (sebum), contributing to dryness and sensitivity.

The circulatory system undergoes a massive change, with blood volume increasing by as much as 50% to support the placenta and the developing fetus. This increased fluid demand places a high priority on internal organs, which can lead to decreased hydration at the skin’s surface. The body’s metabolic rate also increases significantly, peaking in the third trimester. This higher internal temperature and metabolic activity can increase transepidermal water loss, causing moisture to evaporate faster from the skin.

Pregnancy can also exacerbate pre-existing skin conditions. Individuals with a history of eczema or psoriasis may find that hormonal shifts trigger a flare-up of dry, itchy patches. The physical stretching of the skin, especially over the abdomen late in pregnancy, also contributes to dryness and itchiness in localized areas.

Immediate Relief and Safe Skincare Practices

Implementing a gentle skincare routine can provide immediate relief for dry skin. The choice of moisturizer is paramount; it should be free from harsh chemicals or strong fragrances that can irritate sensitive skin. Look for creams containing ingredients that help repair the skin barrier and attract water, such as ceramides, hyaluronic acid, and shea butter. These components lock in moisture and reinforce the skin’s natural protective layer.

When selecting products, check labels and avoid high concentrations of certain active ingredients. High-dose retinoids (Vitamin A derivatives) are advised against during pregnancy, as they carry a potential risk when absorbed into the bloodstream. While low concentrations of AHAs like glycolic or lactic acid are generally considered safe, they should be used cautiously. Mineral-based sunscreens containing zinc oxide or titanium dioxide are recommended to protect sensitive skin from UV exposure, which can worsen dryness and pigmentation.

Bathing habits are another area where simple changes help. Long, hot showers or baths strip the skin of its natural oils more quickly, worsening xerosis. Opt for short, lukewarm showers and use a gentle, non-foaming cleanser. To maximize hydration, apply moisturizer immediately after gently blotting the skin dry, ideally within three minutes of exiting the water. This practice, often called the “three-minute rule,” seals the water into the outermost layer of the skin.

Environmental factors can also be managed to support skin health. Using a humidifier in the bedroom, especially during dry winter months, helps maintain moisture in the air and prevents the skin from drying out. Wearing loose-fitting clothing made from natural fibers like cotton allows the skin to breathe and reduces friction. Maintaining adequate hydration by consistently drinking water supports overall skin elasticity and moisture from within.

When to Consult a Healthcare Provider

While most dry skin during pregnancy is simply a nuisance, certain symptoms warrant immediate consultation. The primary red flag is severe, unrelenting itching (pruritus) that is not accompanied by a rash or does not respond to simple moisturization. This intense itching can be a symptom of a more serious, although rare, liver condition called Intrahepatic Cholestasis of Pregnancy (ICP).

With ICP, the itching is often worse at night and may be concentrated on the palms of the hands and the soles of the feet, though it can be generalized. If you experience severe itching, contact your OB/GYN or midwife right away. They will likely order blood tests to check liver function and bile acid levels to rule out or diagnose ICP. Early diagnosis is important for managing the condition and ensuring the well-being of the fetus.

Another condition is Pruritic Urticarial Papules and Plaques of Pregnancy (PUPPP), which presents as a very itchy, bumpy rash that typically begins on the abdomen. While PUPPP is intensely uncomfortable, it is not harmful to the baby. Only a medical professional can accurately distinguish between common pregnancy itching, PUPPP, and the potentially more serious ICP. Therefore, any severe or distressing skin symptoms should always be evaluated by your care team.
