From the description it seems you are probably having seborrheic dermatitis
alone or seborrheic dermatitisand rosacea together which may coexist.
Seborrheic dermatitis is characterised by dry flaky skin over eyelids, eyebrows, nasolabial folds, behind ear, scalp, upper chest, back , groin, limbs ( flexors) etc.
To treat the same use an anti dandruff shampoo containing ketoconazole
three days in a week
To treat dry skin over face, use cetaphil
cleanser and moisturiser and apply a mild steroid antifungal cream( you may mix and apply hydrocortisone
cream) for not more than a week. As steroid can exacerbate rosacea if used for too long.
With the above suggestions, your skin would be better. To take care of rosacea, use of sunscreen daily is mandatory. Avoid spicy, hot food, alcohol etc. Vascular form of rosacea responds best to IPL. You may also try applying Azelaic acid cream to reduce redness and swelling.
I would recommend a dermatologist's visit so that a proper skin examination can be done to evaluate your skin problems in a better way.
