I started having dry skin and Rosacea (nose only) Winter 2017 after injections for osteoporosis (first side effect is dry skin). Dropped my pricey Skinceuticals routine, which made skin worse and very sensitive, in favor of PC because of price, no fragrances, guarantee, honesty about ingredients,etc. Skin Recovery routine was good, but at night I still struggled with red patches and tightness. Bought Skin Clinical Moisturizer, which helped but still woke up red. Then came this mask- first I used it for 20min every once in a while, and skin flushed. Slowly skin accepted it better, and this Winter I've used it everyday in the AM as moisturizer- got the idea from reviews, which is healing my skin! I put it on when I wake up and leave as long as possible until I wash my face, sometimes 3hrs. I still can't use it for the whole night, but the everyday use has made skin less red and have fewer flushes, which makes it easier to use only Clinical after Omega serum at night. Lifesaver! FYI I'm 52, medium to fair, on Tretinoin 0.5% for many years, 2-3x/wk. Use Skin Recovery cleanser/toner, 8% AHA lotion, Omega serum, Clinical moisturizer, Hydrating mask daily during cold weather.
