For those needing ceramide replenishment, a highly concentrated ceramide substitute cream containing only two lipids, Questamide H (ceramide substitute) and free fatty acids, is used once or twice a day. Clinical Lipid Therapy® Cream A is for those who need extra ceramide substitute lipids for their dry and sensitive skin. Zero fragrance, zero lanolin, zero propylene glycol, and preservative free, this cream is for everyone - of all ages! How To Use Creams A & B Actually, pure water is the best moisturizer for dry skin. Just add water. First, hydrate the skin. Soak or shower your body in water for ten or more minutes. You may cleanse with a very small amount of True Moisture® Gentle Face & Body Cleanser. Do not use soap, as harsh soap will strip your protective oils. After your bath, lightly spray your entire body, all over with lots of distilled water. Do not towel dry. Use your hands to wipe the excess water from your body. At this point, to protect your newly replenished water from evaporation, and to seal in your new True Moisture, liberally cover your hydrated body with gentle, non-irritating, preservative free True Moisture® Clinical Lipid Therapy® Cream A or B. Think of your 24 hour day as two 12 hour treatment periods. For the first 12 hour period you should apply only Cream A one or more times during that period. For the second 12 hour period, apply Cream B only, one or more times during that 12 hour period. Severe dry skin will require extra True Moisture® Cream. Apply cream to your entire body, rather than to spots or small areas. Note: You may need to reapply the Creams many times during the day, especially if you wash your hands frequently or if your skin is extra dry. The more you use the Creams, the greater the Clinical Lipid Therapy® your dry skin will receive.
