Jan Mariani I c esta face serum

Great vitamin c serum. My wife and daughter live it. I use it when I go out in sun for zeta uv protection under my sunscreen. Brightens skin reduces pigmentation and helps protect. Pricey but well worth it.

My GOAT Vitamin C Serum

I have tried sooooooooo many Vitamin C serums, and I just keep coming back to Jan’s. It’s stable, smells light and fresh, and applies beautifully. My skin starts looking visibly brighter and more refreshed after only a few days of using this serum. I’m done trying others. This is my Holy Grail C Serum for life.

Amazing stuff!

This product took my skin to the next level. I am 61 with hyperpigmentation and asian skin. It has brighten my skin and reduced some but not all hyperpigmentation. I use a primer and foundation as well. Many people have complimented on my skin. Though it may be pricey it is worth it. I use it twice a day. I also use the bioclear lotion too.

Smells nice, no results.

Used the whole bottle and saw no improvement. Has a light fruity scent and a light texture. Too expensive.

BACK TO JAN!

Over the last year, I had slowly let my skin care routine fall by the wayside, using generic soap and body moisturizer. Recently I decided to jump back into Jan Marini and...what an instant difference! I use her four basic products (this being #2) and my skin is already smoother, clearer and age spots diminished.

Jan Marini C-ESTA Serum

I was an avid user of Cesta Vitamin C, but decided to give some other brands a try. When I went back to the Jan Marini vitamin C, I was not happy with the performance, thinking that maybe they changed the formula. I will not be repurchasing this product.

No opinion

It was just okay. I felt like my skin got irritated a little and I had to lather a rich moisturize on top. Not convinced about the ingredients as well.

Amazing!

The serum is worth the investment and I love it! It goes on nicely under makeup and it makes my skin feel so smooth, bright and hydrated. I have fair/sensitive skin and this product does not cause irritation. It is now a staple in my AM routine and I will be repurchasing!

Serum has small granules in it.

I really like this serum. However, this one has small granules in it. It doesn’t seem to affect how it goes on my face. But this is the reason for 4 stars instead of 5 stars. My previous container of this same product did not have a grainy feel. I am wondering if formula has changed. And, I shake the bottle before using.
