iS CLINICALPro-Heal Serum Advance+ - Antioxidant-Rich Vitamin C Serum, Calms Sensitivity & Irritation, Helps Redness, Anti-Aging

I may be just out of graduate school needing to budget but this is one product in my skin care regimen that makes or breaks my skin. The hydration it seals in prior to moisturizer, protection properties, redness/acne, — personally, I feel this serum is just a miracle in a bottle… it is pricey, but it is worth it. I’ve used all the top tier brands and I still use my Zo moisturizer and get the complexion pads when I get — but this serum is everything. Quality 10000/10.

This serum is 1 of the 2, I use daily with my IS Clinical routine. I am in my late 60's, but have been told my face/skin looks like I'm in my mid-50's !

Expensive but worth it! My skin looks healthy and happy. I have pretty much always used foundation when going out, but while using this product I am more confident to forgo the foundation because my skin is smooth and glowing. It’s really worth the money unfortunately lol. I’m sold. But be careful with the dropper. It’s not a secure top. I spilled some once and being that it’s so pricey - I was pissed!

I read about this somewhere and tried it. My 20-something daughter commented right away that it "looks like 2015" aka took 10 years off. I use it in the am after cleansing and before moisturizer and I can stretch it to almost 10 months. So, at $16/mo, I guess it's worth it!

I'm a big fan of this product (Vit C,A,E), but not sure spending this much is necessary. I have bought the same product in a different, and cheaper brand, and can't really tell the difference.

This product is pricey, and I read lots of reviews, which I don't always believe. I have to say the reviews were right on. Most of them complained about the cap coming loose. This serum is like a miracle! My Dermatologist put me on pills to get rid of breakouts (I am 75 so it is not Acne). Nothing worked. Then, accidentally I came across this product and said what the heck. Overnight there was improvement and in 2 days my face was clear. I will use this till I die (which I hope is many more years).

I find it super weird how this product makes my lips numb doing some research it’s because of one of the first couple ingredients that when used in high doses can make your lips numb but for the price it seems a bit weird to have that as an effect??? as much as I want to see if it really makes a difference with my skin it’s just super uncomfortable to have a numbing my lips, so definitely going to return:(

I have being using this product for about 3 years now and it’s truly a great product, it really hydrates your face, it really gives you an amazing result.
