Product Description

 Rejuvenating Facial Serum with Ester-C


We formulated Rejuvenating Facial Serum with Vitamin C Esters as a natural, gentle wrinkle fighter. Created with light, non-greasy Aloe Vera gel and precious plant oils. This Serum is a restorative moisturizer for refining the fine lines, wrinkles. It also serves as an aid for dry maturing skin. A perfect solution for skin which has been damaged by environmental stress. This product absorbs quickly and easily into the skin and can be used as a day or night time treatment. Used alone until you have tested this product for sensitivity then it can be used in conjunction with other facial care products. Excellent as a daily moisturizer for all skin types, especially oily skin.


Ester-C is a patented form of Vitamin C, which is more bio-available and more concentrated than other forms of Vitamin C. It protects cells from the damage caused by free radicals by providing anti-oxidant protection. Ester-C is highly recommended by Nicholas Perricone in his book, "The Wrinkle Cure," for the treatment of wrinkles, and weather damaged skin and overall nourishment of tissue.


How To Use:

Apply once or twice daily to the face and around the eyes. This product absorbs quickly and easily into the skin. Useful as both a night or daytime treatment. Can be used alone or with other facial care products after testing for skin sensitivities.

  1. Wonderful product.

    Posted by Debra on 21st Jun 2018

    I like the quality of Karen's products and this one is no different. I put a light coating on my face after nighttime washing and using rose toner, while face slightly damp. Then I use Calendula moisturizer on face and neck to sleep with. Feels great. not greasy. After reading the other reviews, going to use in morning too before using my Lavender moisturizer.

  2. Anti-aging!

    Posted by Christine on 2nd Nov 2017

    This serum absorbs so well into my skin and I use it as a base layer underneath sunblock ( Karen's lavender cream is a staple of mine as a sunblock!). I am 53 years old and am always mistaken for 15 years younger due to my lack of wrinkles and I have been using this serum for over 7 years!

  3. My day does not start without this product

    Posted by Ansa Sama on 14th Sep 2016

    I have been using this for a few years and it is all I use. If does not feel greasy and my face just absorbs it and my skin feels beautiful. I get lots of compliments on my skin and I am nearing 50! Love it

  4. Best natural product for my face

    Posted by Idem Sama on 12th May 2016

    Love this face serum. It's natural and it works. I get accosted by facial sales people trying to sell me their product and once they look at my skin and ask me what I use, they have nothing bad to say. My combination skin never feels too dry or too greasy. I absolutely love it.

  5. Excellent product

    Posted by Gail on 6th Mar 2016

    This serum soothes my face during the harsh winter and feels so good on my skin. It's now a go-to daily part of my life. Not oily; just leaves your face feeling like silk.

  6. Ester C

    Posted by Unknown on 29th Sep 2015

    I love this product. Something about it has changed though. The color for one and the consistency but it still does the job. I have been using it for years and love the way my skin feels

  7. My skin feels fabulous

    Posted by Ann on 26th Jul 2015

    I love this product for both how it makes my skin feel and the way my skin looks when I am using it. I use it day and night and am thrilled with the results.

  8. Exceptional!

    Posted by Rita S. on 14th Jan 2015

    This serum made a noticeable difference within the first day of use, and, the results are only getting better. I also apply this serum to my neck in the evening and wake up to skin that looks years younger. No commercial serum has ever produced results like this. Finally, an effective, 'clean,' cruelty-free and affordable facial serum. KB's has definitely gained a repeat customer in me.

  9. best serum ever for regular skin

    Posted by Unknown on 10th Jan 2015

    It's winter in Boston & I absolutely am glowing from the neck up due to this serum. Not dry. Not itchy. Not anything I don't want for healthy skin in 20 degree weather. Thank you!

  10. Absorbs beautifully!

    Posted by Deborah on 31st Aug 2014

    Love it -- use day and night!

  11. "Thank you!"

    Posted by Kristina Escalona on 31st Aug 2014

    I see a difference immediately! Love this product, I apply it in the morning after I wash my face, and it acts as a bronzer (provides an overall tan glow), it reduces the appearance of my pores (it's like vitamins for my face, leaves me with a clear one-tone complexion), and it makes my skin feel so soft!
    I really love this product, I lent it to a friend who uses it instead of concealer/blush/powder/etc).

  12. I love this product.

    Posted by Unknown on 13th Feb 2014

    I use this twice a day! It's gentle but works. Nothing dramatic, but I am 53 and my skin looks very good for my age. Years of sun protection have helped, but this product makes a difference!

  13. Excellent Serum

    Posted by Brenda H on 6th Feb 2014

    I have been using this serum, along with a couple of Karen's face creams, for a few weeks now. My face feels softer and more supple than ever. I especially love that my sensitive and allergy-prone skin is doing so well with this product. This is an excellent serum that I definitely plan to keep using!

  14. Wonderful serum

    Posted by Cheryl on 9th Jan 2014

    I tried the sample and ordered the regular size as my skin felt wonderful with the serum. I wear it under the Sensual Amber Sage Cream and even in the Santa Anna winds my skin still feels moist. And the ingredients are nontoxic.

  15. Hydrating

    Posted by f.california on 10th Dec 2013

    I like the way my skin feel after I put this serum on. It feels soft and hydrated. I use this after my Melissa toner and be for calendula and rose cream. The combination is just heavenly.

  16. Facial Serum

    Posted by Thea Krauss on 26th Aug 2013

    My skin really soaks up this serum and does feel better and more moist.

    Only problem is the dispenser which is too long and doesn't pump out the lotion. I cut it too shorten and may have to do it again, as it still doesn't work properly. I end up wasting much of it when I try pouring it out.
    Other than that, it is very effective.

  17. Love this product

    Posted by Kat on 16th Aug 2013

    This is a great product full of antioxidants. It has a nice light feel and I use it daily under my daily lavender moisturizer

  18. Younger skin!

    Posted by Christine on 5th Aug 2013

    This serum blends well into my skin without leaving it greasy and every since I started to use it along with the green tea serum, my friends have remarked that my face looks healthier and younger, with wrinkles diminishing and skin looking more pliable!
