Kahina has graced our shelves since 2011, and it’s a brand with a very special place in our hearts: we’ve always admired its integrity, its beautiful formulas, and its trailblazing use of the violet glass that now surrounds a plethora of products, including our own.

Our Kahina collection at Ayla originally didn’t include their Restorative Serum; at the time, we thought, “Well…we have a lot of oil-based serums and face oils, so it might get lost in the shuffle.” (We like to make sure each product on our shelves has the ability to shine.)

But very recently, the Restorative Serum got a glow-up, and it occurred to us that it might be just the thing you could use to soothe, restore, and brighten winter-depleted skin for the spring season. Richer than Kahina’s signature Argan Oil but still light enough to suit a broad range of skin types, it’s packed with calming, brightening, reparative plant extracts and oils (licorice, mallow root, carrot seed, prickly pear) along with their second-to-none argan, and it smells so good that you’ll want to use it on your hair and hands, too.

Doesn’t it sound just right for right now? Well, it’s your lucky day: starting at 9am PT on Sunday, March 30, while supplies last, we’re including a full size Kahina Restorative Serum a $98 value with any $150+ order. (One per customer, please.)

It’ll officially be on our shelves soon; until then, read on to find out why its creator, the absolutely wonderful Katharine L’Heureux, thinks it’s such a hit:

Katharine tells us, “Our Restorative Serum was one of the original 5 products we launched with, and it is a cult favorite to this day due to its blend of unique ingredients, beautiful velvety finish on the skin and an intoxicating scent that I adore. I wanted to create a serum that was oil-based and gentle, yet effective for all skin types utilizing the most superior natural ingredients, and I think we nailed it.”

When asked what makes the new formula so special, she replied, “This upgraded formula is a powerhouse oil blend featuring active brightening and skin-firming ingredients like licorice and mallow root, Sea Buckthorn oil, Carrot seed oil and Prickly pear seed oil. All rich in Vitamins E&K to repair and brighten effortlessly and luxuriously. Once you start incorporating Restorative Serum into your skincare ritual, you will not be able to go without it!”

We agree; look for this gem on our shelves soon.
