iS Clinical Youth Serum ($150) is a product that I am thrilled to have tried. The ingredients in this serum are quite the mix. It has plenty of peptides and bio-identical growth factors. Some of their key ingredients are copper tripeptide growth factor and a vitamin, A, C, & E blend. They have a patented Extremozyme technology that provides UV photo protection and prevents environmental damage. I also notice caffeine in the mix which I have used in other products which helps in the reduction of puffiness under the eyes.
After using the product a few days I realized I could not use it under the eye or around the eye. It was a little drying and I saw the signs of milia developing under the eye, and the eyebrow area was flaky. I did use it on the rest of my face and as far up as my cheek bone under the eye down to the décolleté area. After applying the product I noticed that it does have a slight tightening effect which is nice. My skin felt extremely soft and smooth. It has been a good 5 weeks and I actually think my skin looks tighter. I think with continued use it will get even better. My skin felt hydrated and I didn’t use a moisturizer afterwards, only sunscreen. Being that I am almost 56 years old that says a lot to me.
If you view information on their website you can read a clinical study that was evaluated for its ability to encourage collagen synthesis in aged human fibroblasts. Quite a fascinating read. The end result was the Youth Serum definitely improved the collagen production. There were positive results seen as far as changes in the aging face such as sagging, wrinkles and loss of firmness.
I would say in 5 weeks I am impressed with the results and the packaging is nice as well. The serum is a nice consistency and comes in a dropper form. There is more than enough in 1 dropper to do my whole face and neck and probably a half for the décolleté area. I only used the serum in the morning and I still have some left after five weeks. It is a bit pricey, but I for one am not shy from paying $150 for a great serum that does exactly what it says it will do. So I would say that iS Clinical Youth Serum would be on my list to definitely try. I am not sure yet on where it stands next to my favorite, Medik8 Firewall, but I would certainly say it is in the running for the top spot. I will continue on using this serum until it is gone and see what happens.
