That shampoo with salicylic acid might be causing some irritation. You might want to try something more gentle, maybe just use the ketoconazole, or alternate it with a generic shampoo. If you wanted to try a steroid, I'd try something like Synalar .025% cream. (fluocinalone acetonide) Betamethasone, depending on how it's formulated, ranges from medium-high to very high potency. I'd stay away from it except for rare occasions when something milder wouldn't work, and never use it for long duration. If hydrocortisone works, just use that. I would also visit your dermatologist to see if another liquid nitrogen treatment isn't called for, or maybe some other form of destructive treatment. Sun-induced lesions like this tend to respond pretty well to freezing. I've had a million of them. If freezing gets the job done, that would be better than constant steroid use.
