Hi Denise
I think you have a complicated skin type that has eczema AND acne at the same time.
If the back acne is bad, what we should do is solve the acne first through medications and improve your skin quality. However, you will also need consistent moisturisers to alleviate your eczema.
Once it is improved, tail the oral medications down and then optimise the topical options using light peels, light moisturisers.
I have done such things for my patient who had acne AND eczema on the face.
