I cannot find another line that delivers the same results. I use many products from iS Clinical & Pro-Heal is a favorite! It keeps my complexion redness under control & I believe it delivers great anti-aging benefits!
newest addition to my skin routine

I use this product every morning. Leaves zero residue on the face. It goes deep into the skin, which is what you want. Love, love, love. Really helpful for painful, inflamed cystic acne.

Pro Heal Serum

For my skin, this is the best vitamin C product. I have rosacea and you wouldn't know it. This keeps my skin clear. I've been using it for years and have no plans to stop.
The perfect serum
Posted 6/10/2015 by Michelle
This serum is a little lighter than Skinceuticals CE Ferulic and a little heavier than Skinceuticals Phloretin CF. I like them all, but this is my go-to. I layer Hydra Cool Serum on top and my skin is very happy.

Can't live without
Posted 1/13/2015 by nmalaya
This serum is the perfect formula to help protect and nourish your skin day and night.
I've tried many other serums with vitamin C, but they are often too harsh for my sensitive skin. The name couldn't say it better - it really is healing.
I particularly love how I feel like my skin is sealed up and protected once applied.

If you have sensitive or acne prone skin, this product is a must...easy to use and quite effective!
Worth the Price
Posted 4/15/2012 by M
I've purchased this several times and have found it is worth it. I'm in my early 30s and have sensitive skin. It has really strengthened my skin and I've seen a difference over time in skin brightness and fine lines. It is also soothing when I'm using retinols and is mild enough to use around the eyes. I only use 5-7 drops once a day so it lasts quite a while. You do have to be a little careful with the glass dropper, but it's really easy to use every last drop, which isn't always true with serums that are dispensed through a pump or tube.
Cold sores no more
Posted 12/21/2011 by soozyque
This product helps heal cold sores faster than anything I've tried. The last one I got didn't blow up and the recovery time was days faster than usual. I've gotten friends to try it and their results were amazing. Really aids the healing process.
LOVE this stuff!

I'm probably more thrifty than most people, and I think this stuff is absolutely worth the price! My dermatologist recommended it to me and I love it! No other product, prescription or otherwise, has cleared up my blemishes so quickly. I literally saw results within hours.
