Wondering how to best treat flaky, almost scaly, small, red circular dry patches on my arms and shoulders. I'm very fair skinned, with freckles, and live in Canada where I get very dry skin over winter. I get these 1 centimetre-size spots of dryness up & down my arms. No amount of exfoliating or moisturizer helps. Just bought Bio-Oil, but am wondering if there's something else I could be doing.
