Fellow eczema sufferer and scaly skin dragon here! I'm forever searching for the HG moisturizer (because despite my persistence I find oils e.g. coconut, almond etc. just sit on my skin rather than soak in) but in the meantime here is some of my routine:
My face is particularly sensitive and gets incredibly dry, flaky and bothered. I exfoliate with honey that has crystallised (i.e. has grainy lumps of sugar in it) with lukewarm water to wash off.
I've tried multiple cleansing oils/waters/milks etc. but seriously Bioderma Créaline Sensibio micellar water is the only thing that works without stripping my face. Followed by Avene Eau Thermale.
Fluctuating temperatures and weather conditions means the only creams on my face at the moment are Vaseline/Waxelene/Aquaphor/Homeoplasmine. However I'm soon to purchase
La Roche-Posay Hydraphase Intense Riche, because after multiple testings and plane journeys later, it doesn't irritate and actually keeps my skin moisturized. The Toleraine range is also vv good.
For the body, take a lukewarm bath with Bicarbonate of Soda (2-3 tablespoons is enough, but more won't kill you!), soak for 5-10 minutes, then pat dry with a bath sheet (preferably cotton, not a fluffy towel).
DO NOT MOISTURIZE AFTER THE BATH. Skin will be silky smooth - and it should kill the itch for eczema sufferers.
For the scalp (majorly scabby flaky scalp, wow, what a sexy desirable creature I am) I use diluted apple cider vinegar, and make sure to keep my hair and scalp clean, especially washing after exercise - the sweaty build-up just increases the itch-factor.
ps. how much do you want to punch people in the face when they're like "oh, have you tried using a lotion?" like
no, never in all my years did I think of trying a lotion for my dry skin *eyes-rolling-into-the-back-of-my-head*
