Product Overview

A powerful Vitamin C antioxidant cocktail serum with Vitamin B5 and Hyaluronic Acid for additional hydrating benefits
What it does:
C-ESTA Face Serum is a powerful antioxidant cocktail, featuring a lipid soluble form of Vitamin C, DMAE and hyaluronic acid to help reduce the appearance of fine lines and wrinkles and uneven skin texture while simultaneously protecting the skin from free radicals caused by UV exposure and environmental stressors.
C-ESTA's lipid soluble form of vitamin C enables this potent antioxidant to substantially assist the skin without the need for harsh acidity levels required by traditional forms of Vitamin C - meaning superior benefit with less irritation. DMAE enhances Vitamin C's benefits by helping to further reduce the appearance of fine lines and wrinkles giving facial contours a tighter, firmer, more "lifted" look. C-ESTA Face Serum is the preferred Vitamin C and antioxidant solution for younger, healthier looking skin. This facial serum is great for all skin types.
Study Results:
In a split-face Vitamin C study study published in the Journal of Drugs in Dermatology comparing C-ESTA to a leading vitamin C product, C-ESTA Face Serum was shown to reduce the appearance of fine lines and wrinkles while providing superior benefits to the leading traditional Vitamin C. C-ESTA Face Serum was also significantly preferred by study subjects over the leading traditional vitamin C.
How to use:
Shake bottle well. Apply antioxidant face serum sparingly morning and evening to clean skin. Apply over entire face, neck and behind ears.

    Highly impressed with this product

    Posted by Zalie Formann on 16th Apr 2024

    I am a lover of many Jan Marini products. My usual revision vitamin c ran out and unfortunately the products are getting harder to find in Australia. I love all my other Jan Marini products so I thought I’d give this one a try and I am very impressed. Not only have I seen results in such a short period of time but this product is over $70 cheaper than the one I was previously using so that is a win for me. I have seen fading in my pigmentation spots already and I am only a month or less into this product. The smell is strong but doesn’t last and does not bother me. I will definitely be repurchasing again

    Can not live with out

    I do not need to use more than one pump per day, every day, to keep my skin looking good. When I have a facial, my beautician says my skin is in great condition

    Love this product

    I love this product. Very light and instantly absorbed. It also makes a great primer under makeup. It’s amazing that such a light serum can be so hydrating. The look of it on my skin makes my pigmentation less noticeable.
