In their special beauty issue, Stella highlights the best skincare ranges you've never heard of, including Kahina Giving Beauty.

"Katharine L'Heureux, a Californian, developed Kahina Giving Beauty after discovering the healing benefits of argan oil on a trip to Morocco. Her products are based around this, with money going back into the Moroccan co-operatives and to the Berber women who extract the oil: their signatures grace the packaging.

KEY PRODUCT: The Eye Serum wakes up tired eyes and helps to diminish dark circles."
