Usually I have oily-combination skin but for the past two months I find myself with flaky patches of skin (left temple, right cheek, under chin, behind ears). I haven't made any drastic changes to my skin care and I currently use CeraVe moisturing cream and recently I've been mixing in argon oil which helps with the old dry patches but now there's new ones (along my jawline connecting to the back of my right ear). Any advice? I exfoliate 4 times a week with st. ives apricot scrub which I've been using for months without problems, and cleanse with an African black soap which I've used in the past with no problems either.
