NOT for rosacea or ocular rosacea!!
Size: 1 Ounce (Pack of 1)
NOT for rosacea! I have rosacea and ocular rosacea. I did a test on the side of my cheek. It seemed to go OK…. When I used it on my entire face, I paid for it for two days!! Caused a nasty flare. This product has GLYCOLIC ACID, very low levels of it, but it does nonetheless. It was a disaster for me.

Like but...
Size: 1 Ounce (Pack of 1)
Was nice and light on my skin but did not see much improvement of redness after 6 weeks. No fragrance, did not irratate skin. May try another bottle incase it wasn't enough time to see results. Overall I like the product just not the results at this time.

Not an eye cream, but makes a great eye cream
I use this as any eye cream before applying my prescription tretinoin cream. Its provides a good barrier for my sensitive eye area without feeling heavy. Its large so it is a great value for my money. It is light weight, not greasy, unscented, and is great for my sensitive skin. I am prone to millia and haven't had any issues since switching to this for eye cream.
