I have extremely sensitive skin. Seriously, most skin care will make my skin flare up in hives for days then cause dry patches for weeks. I've tried it all. PC skin cleanser has been a savior for me for years but my skin is very dry and I noticed some damage around my eyes and nose from hives on and off. I had wrinkles, discoloration and flaky skin (which is abnormal for a 24 year old). I use a few other PC products but I needed something to REALLY moisturize my skin without clogging my pores. After some research I gave this serum a try and HOLY SMOKES! My skin looks the best it has in years and I couldn't be happier. I would recommend this to anyone who is considering if this would work for them!
