Kahina Giving Beauty Serum- reviewed and recommended

March 13, 2012 Reviewed by Marta 8 Comments

I met the founder of Kahina Giving Beauty, Katharine L’Heureux, a month or so ago over a cup of coffee. She was absolutely delightful, her company with its argan oil based products has an impressively ethical mission, the products look fabulous and are even glamorous enough to be accepted in to the haloed shrine of the Bergdorf Goodman beauty department.  The Kahina range is totally organic and safe enough to be beloved by cancer survivor and author Britta Aragon whom we interviewed last year. Nonetheless, when Katherine kindly handed me a bottle of her recently launched Kahina Serum, I was secretly a little dubious.

Argan oil is unquestionably a good ingredient that is full of essential fatty acids and vitamin E. But it I feel that it has become a victim of hype and it crops up all the time, often in products that are otherwise not especially interesting. Hair products such as Josie Maran’s or MoroccanOil are a case in point; I’m afraid they qualify as overpriced silicone. I like Zinn’s argan oil range as the products have a reasonable price to quality ratio. A $90 serum on the other hand would have to perform. And, as an additional challenge, it would have to perform on my 50-something skin.

A month later, I am delighted to report that I think that Kahina Serum is an excellent product. What it excels at is making the skin feel firmer, while looking a little plumper and smoother. As part of my test, I have been using it on my hands and see a notable difference – and the most spectacular part is that my nails have been growing so much I have to keep clipping and filing them. I know that argan oil is good for hair and nails as well as skin, but I hadn’t expected talons to grow before my eyes.

What makes this stand out from many of those argan oil products that I referred to earlier, is that argan oil takes center stage and the rest of the cast is pretty A-list as well. There’s coffee seed and pomegranate, which are rich in antioxidants. Sea buckthorn extract also has great credentials with plenty of vitamin C, vitam E and folic acid. There’s also rosemary, a herb that tends to be overlooked by the cosmetic industry. Carnosic acid and carnosol are the most important active components of rosemary extracts.  Carnosic acid and carnosol have been suggested to account for over 90% of the antioxidant properties of rosemary extract and are slso powerful inhibitors of lipid peroxidation. The only thing in the formula not to like is linalool, a compound that is possibly carcinogenic.

Kahina Serum has a pleasant, flowery fragrance and is an oil with a medium to light consistency. My estimation is that the 1oz bottle could last for a good three months or more. While using it, I like knowing that Katharine has made multiple trips to Morocco to personally source the oil and ensure the ethical treatment of the women who work to extract it. As a testament to them, their actual signatures grace the stylish packaging and they receive a portion of Kahina’s profits. While, I my 50-something skin responded well to this serum, I think it would be a great choice for 40-somethings and as a preventative for 30-somethings.

    I got this serum as a sample in my vegan beauty box Petite Vour and used it in the mornings. (Didn't know it was recommended on Kahina's website to be used at night.) I don't usually find products I love but I love the way the oil absorbs and didn't oily and I felt that it make my skin look brighter and the tone more even. My sample only lasted 2 days cause I spilled some but I'm sold. Hoping it's not too oily for the humid summers in Chicago. Thanks for speaking to this being a good preventative product for 30 somethings.

    Like most of us in the TIA community, trying out different products to determine what really works for you is important, specially when it comes to eye creams. I'm hoping to try Kahina products and thoroughly enticed with this review Marta just posted.

    Hi Katharine, that's really helpful information and I shall remember that when I come across linalool in the future. Thank you for taking the time to hop on and comment.

    Dear Marta,
    Thanks for the lovely comments about the Serum. I'm so glad we were able to overcome your skepticism. I'm afraid that many of the argan oil providers out there have not done justice to the amazing powers of this ingredient. I appreciate your help in dispelling the notion that all argan oil is created equal. A note on the linalool - it not an actual ingredient used in formulating the serum. To sell products in Europe, any potential allergens discovered in products are required to be disclosed. The linalool was used in the processing of one of the ingredients in the formula. Although it is in trace amounts in the final result, we are still required to list it on the ingredient list to export to Europe and meet their strict requirements. Hope this helps to clear things up.

    Hi Marta,

    This eye cream is very intriguing with argan oil and other standout antioxidants. At 51 years of age, I am still searching for the perfect eye cream that really makes the eye area look more youthful, yet doesn't cause irritation and especially before applying makeup. It seems like the eye cream and makeup (eye shadow, liner and mascara) don't mix very well for me and I end up with my makeup running off and my eyes tearing up. I have not used skincare with argan oil yet, and would love to test the effectiveness with due diligence to see if the hype delivers real results.

    Hi Marta,

    I have just a few dibs and dabs of the Sen Zen Double Dose Eye Cream left, which I love (and I have you to thank for turning me on to it), but I think it would be great to see how something more natural would work on my 50+ crows feet and starting to get crepey lids.

    I am 62 and always looking for a new eye cream. I'd love to try one that uses natural ingredients.

    Even though I just bought a new bottle of YBF CORRECT I'd like to try this eye cream, too. A side by side test would be very interesting. thanks! Sue
