I started using this wonderful product about two weeks ago, as part of my nightly facial routine. I love that it is moisturizing without feeling heavy or sticky. I use it not just around my eyes, but over my entire face, neck, and ear lobes (they are prone to wrinkles, too!). I also have started rubbing a dab of it over a scar I have had for several years, and I think it I am beginning to see a difference. I just love Karen's Botanicals!

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.

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

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

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.

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.

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).

Love it -- use day and night!

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!

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.

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

I have been using Ester C for over 15 years now, and I absolutely love it!!!

I love this product. I had initially wanted to try this serum for the wrinkle fighting claims. I am going through perimenopause and my skin has been getting fine wrinkles and has become very dull. Youth Rejuvenating Facial Serum with Ester C has been wonderful for my wrinkles and has brightened my skin. As an added benefit, it has completely cleared my hormonal acne on my jawline, cheeks and chin.

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!

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.

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.

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!

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!

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.

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.

Thanks,

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!
