helping rosacea [SEP] Before getting azelaic acid RX I wanted to test because my skin is EXTREMELY sensitive and reactive to just about everything nowadays.  This is pretty great.  Definitely soothing my skin more than just about anything else in recent years.  I generally avoid silicones in skin care but harder in makeup, but this is not bothering me.  Can't speak to long term exfoliating or pigment or clearing acne uses but as extended "patch test" I was pleasantly surprised.  Silicone feel of a primer 'finish,' matte look but clear, no tint.  I don't use primer much at my age but would likely work instead.  More of an SPF tinted moisturizer/BB or green CC type now.  Reminds me of Dr Brandt pores no more texture but more luscious (these days I'm more Dr Jart/Shisedo BB).  Doesn't dry my tight, sensitive skin but no oil to absorb here.  Compared to adalpene, gly/sal, lactic acid, etc. very comfortable, no problems after a week of use am/pm.  I would definitely recommend trying for rosacea, acne, sensitivity, dullness, aging.  By far my favorite product from TO.  Paula's choice AA booster has SA which sensitizes my skin like crazy.  Glad I tested it out, first product that is a keeper in a while, my skin has been so intolerant.
