Joan L

Posted by iHerb Customer on May 27, 2008 | Verified Purchase

I teach makeup/skin care classes, and this product is No. 1 on my "Must Use Daily" list. It's been my personal favorite for years, and my own skin is testimony as to the efficiency of what I teach! It's as close to "miraculous" as a treatment can get!

Thanks for your feedback!

Buy It!

Posted by PeppermintPattie on Jul 08, 2012 | Verified Purchase

I bought Jason's Hyper C Spot Treatment because of some facial discolorations, a large area on my forehead and a splattering of possible age spots/tanning spots on both sides of my cheek bones, lower cheeks and just above my top lip line. I have used the product only on the areas I mentioned for just short of 1 month and the fading is notable. I hope to see even more fading in the next month!

Thanks for your feedback!

This is a great product. I use it on my face as a night cream. I am 74 years old, but people say my skin looks like I am 50+.

Thanks for your feedback!

Jason Hyper C Serum

Posted by iHerb Customer on Sep 14, 2011 | Verified Purchase

I use it about twice a week at night after exfoliating. I have dry, agiing and sensitive skin (I'm 46), prone to redness and an occassional breakout. This stuff heals your skin.

Thanks for your feedback!

Good for hyperpigmentation and moisture

Posted by iHerb Customer on Jan 09, 2009 | Verified Purchase

I think this product is good for hyperpigmentation as well as moisture. But I think the product has made me break out in some pimples and whiteheads due to it being a big oily. But I have kept using it anyways and those problems are clearing up.

Thanks for your feedback!

Not good

Posted by iHerb Customer on Dec 06, 2008 | Verified Purchase

This serum is both sticky and oily at the same time. Would not recommend it.

Jason Hyper-C serum

Posted by iHerb Customer on Sep 10, 2008 | Verified Purchase

This has long been one of my favorite products. Your company provided it at the lowest cost of any on-line retailer. It arrived very promptly, well-packaged.

Thanks for your feedback!

good vitamin C serum

Posted by iHerb Customer on Dec 01, 2008 | Verified Purchase

This a good oil-based vitamin C serum - especially for me with dry skin. I was initiated into using this product by a lady in a sundry shop selling natural skincare. She said the skin gets better and clearer with time. This is true. I find my facial skin becomes very smooth. I buy from iherb because it is best priced. Thanks.

Ester-C Serum

Posted by iHerb Customer on Apr 18, 2010 | Verified Purchase

I tried this serum to restore some vitamin-C to my skin but I found it to dry my skin out and it was very harsh. There are other vita-c serums I have tried that work very well w/o the harshness and drying effect. I was not happy with this product at all.

Thanks for your feedback!

They Changed it!

Posted by iHerb Customer on Aug 12, 2011 | Verified Purchase

Though I like the new and improved formula. The I-herb discription did not state this and I was unaware of any improvements. I would have appreciated the update on the discription.

Thanks for your feedback!
