5.0 out of 5 stars OMG! I hate this abbreviation, but I can't think of anything better!

Wow! I don't even know where to begin. First, I want to state that I have had cystic acne for a couple years, and nothing I tried seemed to work. I have some scarring due to the acne. I have spent so much money, tried everything (and I'm talking about prescriptions too). Finally, I developed an infection in my chin that spread into my gums and into my glands caused by a cystic pimple, which left a huge, huge scar. A few days later my order for the active serum and the cleanser arrived. At the same time, I started on a probiotic and changed my birth control. As soon as I started using it, I saw a difference. My skin felt like it was healing. I kept asking my husband, do you see a difference? Of course, it took about a week for other people to notice it, but I felt the healing right away. I've been using the cleanser, the active serum and the super serum for about 4 weeks now, and I haven't had a single cystic pimple since. I did get a few small zits, but nothing significant, especially nothing new in my trouble are (my chin). Everything is clearing up, my skin is healing and it's GLOWING! I have already told about it to all the girls that I know who are struggling with acne, and some have started using it too. I can't believe that there isn't more info out there about the IS Clinical products, this stuff is amazing! I even noticed a disappearance of a few fine lines I had on my forehead between my eyebrows. I wasn't too worried about that, my main concern was my acne, but that is definitely a plus (*just want to say I'm 25). Want to state again: I started using a probiotic, a new bc prescription and the IS Clinical system all at the same time. So I'm sure it's internal as well as external.

Maravilloso

I really liked this product. I've been using it for a few days and I'm already noticing noticeable improvements – my skin is becoming more hydrated and fresher. The texture is pleasant, non-sticky and absorbs quickly. It has a light, subtle fragrance that is not too strong. The packaging is convenient, and the pump works flawlessly. I think it is suitable for both dry and normal skin. It really exceeded my expectations – I will definitely order it again!

I love IS clinical product. Specifically the active serum and hydra cool. Active serum is great for reducing the look of dark spots on your face and reduces the size of pores. Highly recommend as part of your daily routine. I've been using this product for years. It is pricey, but definitely worth it!

Great product. Already on my 3d 1 oz bottle. Lasts 3 months which is good value. I have a combination skin type with occasional break outs + areas of hyperpigmentation. I do not have many wrinkles as yet. So the main difference I saw in overall improvement of skin quality. It cleared 99% of breakouts and made hyperpigmentation slightly less visible, though no dramatic changes here. Great overnight serum as do not need to apply anything else and skin looks and feels great in the morning. Will highly recommend this product and will start trying others from the same line.

Instead of clear serum yellowish serum was received this time

Ordered 3times as I like this serum. But this time color of serum was pale yellow instead of original clear liquid. But it is disappointing that it's nonreturnable and costly product.

5.0 out of 5 stars Wonderful serum

I really love this serum! Pores appear smaller and pimples minimize with long term use. I do experience mild tingling on application that subsides quickly. Not bothersome at all, though.
