Rated 5 out of 5 by CDub from Ok people, I'm a believer This actually works. Im not paid to write this...in fact quite the opposite, I paid a truck load of money for this ha. I have Mediterranean skin and two dark spots on each of my cheeks. Trying to avoid IPL, I use an exfoliating cloth to scrub any dead skin cells and use these two products plus SPF they gave as a free gift. Yeah a difference. They are not gone but 50% lighter. Probably will be 35-40% in the end and then maybe a few IPL's. Regardless, SkinCeuticals is legit and these two products do help. I will add you need to be diligent. None of this when you remember business. No do it morning and night. Also as a tip that maybe everybody knows and I'm the last to the party, but tilt your head back and drop it directly on your face ...gently mind you. The finger transfer is a mess.

Rated 3 out of 5 by Lo7206 from Not effective after less than 3 months I’m extremely disappointed that I paid so much for this product. I tried to be conservative with it to make it last, but it hasn’t even been three months and the serum has turned brown and smells like rotten eggs. I was told it’s not effective once it turns brown. This is so frustrating because the product is great and really improved my skin before it went bad.

Rated 5 out of 5 by roxyyb_ from I love all skinceuticals products. This one is def a top fav. I use this right after I tone and it has improved my skin. Im still in the middle of using it so cant tell about the full strength of it. It is very pricey though.

Rated 5 out of 5 by Amie from WORTH IT I have struggled with acne, scarring, and discoloration for years. I have tried SO many products professional and drug-store brands and have never found anything as amazing as Phloretin CF. It is 100% worth the money. I received a sample of it after buying the LHA cleanser, and just from using that sample my skin had already started to change significantly. I gave in and bought the full size bottle and will continue to do so. I feel confident when I'm not wearing makeup, and honestly don't even have to wear much make up now. Highly recommend this product. It is a staple in my routine now along with the LHA Cleanser.

Rated 5 out of 5 by alisonf18 from I just started using this serum and I love it! It does have a strong smell, as most vitamin c serums do. It sinks into my skin and so far my super sensitive skin loves it. Combine this with other skinceuticals products and your skin will be amazing.

Rated 5 out of 5 by LauraB from Totally Worth It I'm 38, fair, with mild acne roseacea. Not only does this give my skin a youthful glow but after a mild purging of a week or so, my acne and any bumps are almost completely gone, redness reduced, and I have a softer, more even complexion overall. Most 'actives' are too harsh for me and the CE Ferulic broke me out. So glad I tried this one. It's expensive but its the only product that's made such a noticeable difference in my skin.

Rated 4 out of 5 by astoldbytaylormb from Great antioxidant! I will say I didn’t give this 5 stars because I don’t love how watery the consistency is. I prefer the gel version, as it is easier to move across the skin without wasting too much of the product.
