Make sure you check the expiration date. Ordered this in May/2025 and received it with an expiration date of 2022!! Quite unacceptable.

I love this product! Love how it moisturizes, and assists with the firmness of my skin. It wears well under my foundation, never pills. Hence it is slightly pricey, but it's worth it to me. 1 bottle lasts me at least 3 months and I use a tiny drop morning and evening. I'm 47 and have very few fine lines due to following my skin regimen and using IS Clinical products.

I haven’t tried anything from this brand that doesn’t work. I’ve purchased Dr Strum, Augustinus Bader and Le Mer in the past. Nothing comes close to IS and I can get it next day

LOVE this product. Not only have I noticed an improvement in my 60 yr old skin, so have others. I love the iS Clinicals line.

Love iS Clinical! First time ordering IS clinical products from Amazon. I chose it because the company confirms the authenticity of this product while other suppliers may tamper with them. That said, the product came straight in the Amazon envelope without any wrapping or seal. Now I’m doubtful.

4.0 out of 5 stars I love iS Clinical products and this is the first time ...

I love iS Clinical products and this is the first time purchasing the firming complex. I was hoping this product would give me both a moisturized feel as well as firmness. I'll be going back to the moisturizing complex. Perhaps for those that want a firming cream only this is a nice product.

Check the expiration date.
