I always use the johnsons baby oil before going in pools and let it dry before swimming it leaves skin soft and moisturised

I can imagine how drying the water can be especially all the chlorine in the pools. Probably best to use a very good intensive moisturiser for the face and body . I am currently using Dermal Therapy very dry skin lotion and it is so soothing and moisturising . It is great for itchy dry sensitive skin as well .

not sure but i used tanning oil a long time ago and it didn’t really wash off in the pool. maybe it is a start for something to coat your skin.
