I have bad facial skin characterised by a red appearance, dry, scaly skin. its not rosacea or derm. what is it

i have been to a dermatitis doctor many years ago where the doctor diagnosed me with seboroic dermatitis, he prescribed a steroid cream that worked sparadically when the symptoms were at their worse. i am reluctant to use the cream as for the effects of thinning of the skin.i currently use dermaid to ease the symptoms when i feel the onset of a breakout. i am looking for some answers to this ongoing problem and would be very grateful for any helpful adviceI have bad facial skin characterised by a red appearance, dry, scaly skin. its not rosacea or derm. what is it
How do you know it's not dermatitis? Keep it well moisturised and avoid using soap on your face.
