Topical steroids come in different strengths, ranging from mild to moderate, potent and very potent. Side effects are more common in high-potency prescription-strength steroid creams. Over-the-counter hydrocortisone is the lowest-potency steroid cream available, but could cause thinning of the skin if used daily for many consecutive weeks. This is especially true if steroid cream is used on thin, sensitive skin such as the eyelids, genital areas, or the folds of the skin. As a general rule, to minimize the risk of side effects, use the lowest strength preparation that is effective. Very potent steroids should only be used for short periods, whereas milder ones can be used longer.
It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens. It can sometimes be difficult to judge how much steroid to use and there are guidelines on the amount required to cover body areas that are affected by eczema. These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
i have this exact symptom after 1 week of TSW (I was on TS for about 7 months, twice daily application to my face.. not sure how strong it was, but i think it was relatively mild). Now whole face is covered in yellow flakes, exactly as you described.. Also I never had the flares etc as you mentioned others often do - nope I never did.. mine was always quite consistent. Anyway - just wondering how long the flakes lasted for you, and if the coal tar soap (which doesnt contain any coal tar btw) worked long term? or if u switched another soap or method etc. Info pls!!
