How pregnancy changes your skin's response to water

Elevated oestrogen levels during pregnancy alter your skin's hydrolipidic film, making it more permeable. Chlorine and limescale penetrate more easily, causing pronounced dryness and irritation.

Many pregnant women find their skin suddenly becomes reactive to things that were fine before — shower water is one of the most overlooked triggers.

Is chlorine harmful during pregnancy?

At normal tap water concentrations, chlorine is not acutely harmful. However, daily skin contact during pregnancy can: worsen eczema and PUPPP, increase TEWL making stretch marks more pronounced, and cause scalp irritation and hair shedding (already elevated during pregnancy).

Note: No study has proven chlorine in shower water is harmful to the foetus. Filtering it is a low-risk, high-benefit intervention with no downsides.

Is a shower filter safe during pregnancy?

Yes, completely. Activated carbon filters work via adsorption — no chemicals added to water. Limpéa cartridges contain only FDA-approved food-grade activated carbon.
