Swimming, Sea Water and Chlorine

Swimming is an excellent, low-impact form of exercise for people with rosacea, but the water environment—whether a chlorinated pool or the salty sea—can pose challenges for sensitive or rosacea-prone skin.

Is sea water beneficial?

Sea water is probably not beneficial but it can be less irritating then swimming pools. Nevertheless, the high salt content can be dehydrating. If you swim in the sea, it's crucial to rinse your face with fresh water and apply moisturiser immediately after.

How to protect skin in pools?

Chlorine is a harsh chemical that can strip the skin's protective barrier, leading to dryness, irritation, and potential flares. Before swimming, apply a thin layer of a simple, occlusive moisturiser to your face. This creates a physical barrier between your skin and the chlorinated water. As with sea swimming, rinse your face with clean water and reapply your regular moisturiser as soon as you get out of the pool.

I am a London-based Consultant Dermatologist and Dermatological Surgeon. I am highly experienced in skin cancer diagnosis, Mohs micrographic surgery, acne, rosacea, acne scarring and laser treatments.

I graduated from medical school in 2003 and have worked exclusively in Dermatology since 2012.

I lead a research team at King's College London investigating the molecular biology of skin cancer. In recent years I have been involved in Media Appearances, including the Channel 5 series 'Skin A&E', where I perform skin surgeries and treat various skin conditions.
