Thanks for the feedback!
In the absence of other symptoms, the basis of treatment is moisturizing the skin and other non-pharmacological measures:
A fragrance-free moisturizer such as Aveeno, Cutibase, Base Glaxal, Cerave and others should be applied as often as needed. The cream should be applied at least 3 to 4 times a day, and whenever the need to scratch arises, if ever.
Avoid scented soaps, and after the bath or shower, avoid rubbing the skin vigorously: instead, lightly pat the skin to leave a thin layer of moisture, then apply the moisturizing cream within 5 minutes of getting out of the bath.
Otherwise, I only suggest monitoring the situation. If it persists for more than 2 weeks without improvement, gets worse, or spreads elsewhere, a doctor should be consulted for a thorough evaluation.
I hope I have been helpful and remain available if you have any further questions!
