Another cause of dry skin during pregnancy is sun damage which can happen all year round, even on cloudy, grey winter days. This is due to the sun’s UVA rays that reach into the deep layers of the skin, damaging its structure and important proteins such as collagen and elastin. These proteins are responsible for keeping the skin soft and hydrated so once they’re damaged, the skin becomes drier. In pregnancy, a woman’s skin also becomes more photosensitive so ensure you apply a teaspoon-sized amount of broad-spectrum sun protection to your face every morning.
