Inquiry about pore treatment

I am writing to inquire because recently, small, bumpy protrusions have appeared densely on my thighs, and my skin has become rough. I had them before, but I am worried because they seem to be getting worse. They look similar to keratosis pilaris (chicken skin), so I would like to receive an accurate diagnosis. If it is indeed keratosis pilaris, I would like to know about effective treatment methods. I would like to know which treatment is suitable—such as topical creams, ointments, peeling, or lasers—as well as the duration of treatment and estimated costs. Please also inform me of the possibility of side effects after treatment, such as redness, hyperpigmentation, or scarring. Since the symptoms are present all over my thighs, I would also like to know how many treatment sessions would be necessary. Thank you.
