This is super niche, and I don't think there are any brands making stuff for such niches. My husband faced this problem (he is a mountaineer, not a diver though) and I did a bit of research, which helped him tremendously. The core issue for pilots, mountaineers and divers is decompression sickness. Low oxygen levels, low/high air pressure and high concentration of other gases, creates nasty rashes. Rashes are an outcome of the exposure.
For such cases, dump your usual emollient-based-moisturizer and use a humectant-based-moisturizer (google these if you don't know); and get something with high concentration of humectants. In brief, humectants pull moisture from surroundings, while your usual moisturizer creates a plastic-like sheet to stop loss of body moisture. If you're operating in a humid/water environment (which also includes professional swimmers), humectants are a must. This saves your skin in a big way. My husband uses this. I personally like No 141 and my husband likes No 142. Use humectants before getting on your wetsuit.
If you already have rashes use No 251 or No 252, depending on your skin type. My husband's skin was badly damaged before he started using them. When he went to a dermatologist, the dermatologist suggested him to stay away from anything acidic. She said, "it's poison for you". The dermatologist recommended this, and that's how we got to know about this European brand. And whole family now vouches for this brand.
Find a good dermatologist, that's another option for you as well.
