I find that my skin really like this product over many other moisturizers. Overall my skin loves cosrx products but it really really likes this PHA moisture cream. I don't know what it is but it sooth my skin and it doesn't clogged up my pores like the klair mid-night blue cream. This product really really hydrates my skin. If they are on sale, buy a set and give it a try... i got mine when they had it for $30.
Great set! Amazing for moisturization and both products are really gentle on the skin!
