I have the most sensitive, acne-prone, hyper-pigmentation skin in the world and can honestly say that I have tried everything out there--Chanel, La Mer, Cosmedix, Jurlique, La Prarie - everything and nothing ever helped. This is a miracle cream, truly. I started using REN about 2 years ago and loved it and then I saw this somewhere but could not find it in the US. SO I buy from Cult and it has really transformed my skin along with other products from the REN line. I cannot say enough great things about this product. It is really the best. I get stopped with questions about my skin all the time and i never even have to wear makeup. I am 30 years old and continue to get mistaken for a student. Try this-you will not be sorry, it saved my skin. All the REN products are great, but this coupled with the Hydra Calm Serum is the best thing that ever happened to my face.
