Why your pregnancy glow is missing (and 4 tips to turn it around)

Growing a baby is miraculous—but let’s be honest, pregnancy can also throw your skin completely out of whack. One of the biggest culprits? Dehydration.

Why hydration matters more when you're expecting
During pregnancy, your blood volume increases by up to 50% to support your growing baby. That means your body needs significantly more water to stay balanced—and so does your skin. Dehydration can lead to dryness, tightness, flakiness, dullness, and in many cases, an increase in sensitivity and hormonal breakouts.

Plus, hormonal changes (hello, estrogen and progesterone) affect your skin barrier function, making it more prone to moisture loss—even if you’re drinking all the water in sight.

Common hydration challenges during pregnancy

• Morning sickness can lead to fluid loss

• You may avoid drinking to reduce frequent bathroom visits

• Changing hormone levels disrupt your skin’s oil and water balance

• Some mums-to-be avoid skincare altogether to play it safe

How to support your skin from the outside in
It’s not just about how much water you drink (though that’s important—aim for 2.3L daily when pregnant, according to the Australian Dietary Guidelines). It’s also about what you put on your skin.

Here’s how to boost skin hydration safely and effectively:

• Opt for gentle, pregnancy-safe moisturisers with humectants like snow mushroom, glycerin, or aloe vera to draw moisture in.

• Seal it in with emollients rich in fatty acids—think baobab oil or shea butter—to strengthen the skin barrier.

• Avoid harsh ingredients like retinoids, drying alcohols, and synthetic fragrances that can strip or irritate.

• Hydrate consistently, morning and night. Skin thrives on ritual.
