Open water swimming in summer looks idyllic from the outside. From the inside, it’s cold water, UV, salt, and a wetsuit that’s been in a bag since February. Your skin takes everything at once.
The combination of prolonged water exposure, sun, wind and friction creates a specific kind of skin stress that pool swimmers rarely encounter. It’s not any one of those things in isolation — it’s the cumulative effect of all of them over a morning session, repeated week after week through June, July and August.
Here’s what’s actually happening to your skin when you open water swim, and what to do about each part of it.
Salt water is desiccating. Osmosis draws moisture out of skin cells when you’re immersed in it, and the effect is compounded by the fact that open water swimmers often stay in the water longer than sea bathers. A one-hour sea swim in summer can leave skin noticeably tighter and drier than before you went in — even if you shower the salt off afterwards.
The solution is to repair the skin barrier after every salt water session, not just moisturise the surface. A barrier repair balm — heavier than a standard body lotion — works by providing the lipids that salt water strips, helping the skin reform its protective layer rather than just sitting on top of it.
Balmy Fox Water Repair Balm is built specifically for this. The beeswax base seals in moisture; the plant oils (including borage and rosehip) support skin barrier function. Apply after drying off, while skin is still slightly warm. It absorbs without feeling greasy and doesn’t leave residue on towels or wetsuits.
Open water swimmers are horizontal in the water for long stretches, with their face, shoulders and upper back directly facing the sky. Unlike running or cycling, you can’t duck behind a hedge or tree for shade. And the reflective quality of open water amplifies UV — the same effect that makes water look so bright on a sunny day also bounces UV onto any exposed skin above the waterline.
UV intensity peaks between 10am and 2pm, which is precisely when most organised open water swims and triathlons take place. SPF applied before getting in needs to be water-resistant to remain effective.
Balmy Fox SPF 25 Mineral Sun Cream uses non-nano zinc oxide as its UV filter. Zinc oxide is a physical barrier — it doesn’t dissolve in water the way some chemical filters do. Apply it to face, neck and shoulders before you put on your wetsuit or swim cap. The tin format means it won’t get confused with your energy gel at transition, and it won’t leak in your swim kit bag.
Wetsuit chafe is one of those problems that starts as a minor irritation and ends a training session or race. The neck seal is the most common trouble spot — it’s where neoprene meets bare skin in a flexing, repetitive motion for potentially an hour or more. Underarms and behind the knees are the other regular friction points.
A good anti-chafe cream applied to these points before suiting up makes a material difference. It needs to stay in place in water, which rules out some lighter formulations. The beeswax base in Balmy Fox Anti-Chafe Cream is water-resistant — it doesn’t wash off on entry and remains effective through a full swim.
For triathletes, the Anti-Chafe Cream also covers the transition to bike and run. Apply before the swim and it will still be working in T2.
Cold water swimming — even summer sessions in UK lakes and rivers — takes a toll on facial skin. The combination of cold, wind on exit, and UV can leave cheeks and nose visibly red and dry. This is a mild form of wind burn accelerated by the cold water temperature contrast.
A barrier cream on the face before entry helps. Some open water swimmers use a thick layer of petroleum jelly for this purpose; a zinc oxide cream offers the same physical barrier function with the addition of UV protection. The Balmy Fox SPF 25 works here — apply a slightly heavier layer to cheeks and nose before getting in.
For a summer season of open water swimming — whether that’s a lake in the Lakes, the sea in Cornwall, or a travel swim in the Adriatic — these three products cover the main skin issues:
Water Repair Balm — applied after every session to repair the skin barrier stripped by salt or lake water. The single most useful product for regular open water swimmers.
SPF 25 Mineral Sun Cream — reef-safe, water-resistant, applied before the swim. Essential for any session over 30 minutes in summer.
Anti-Chafe Cream — on the wetsuit contact points before suiting up. Non-negotiable for anything over 45 minutes in neoprene.
All three are 60g aluminium tins. They fit in a swim bag side pocket and pass through airport security without discussion — useful if your season includes open water abroad.
