Do you have any personal favorite cosmetics sold only at dermatology clinics?

Among derma cosmetics, besides the products sold in stores

You know those products sold only at dermatology clinics or pharmacies?

For example, Zeroid, or shampoos for seborrheic dermatitis, or things like that!

I think those of you who frequently visit dermatology clinics are well aware of this! Perhaps your own Must-have dermatology skincare items Is there one?!

Personally, I think Nizoral (seborrheic shampoo) is really effective! It works well for dandruff and scalp troubles! (However, you should only use it two or three times a week!)
