What is the shelf life of argan oil and your other products? How do I best store them? Our Argan Oil has a two-year shelf life from the time of extraction. We buy our oil in small batches several times a year, so you can be sure that Kahina argan oil is fresh when it reaches our customers. Once opened, our products do not need to be refrigerated; however, they should be kept in stable temperatures and, if possible, away from direct light. That said, refrigerating products, especially if you live in a hot climate, will help preserve them. Refrigerating our eye products (Eye Serum and Eye Cream) makes them more effective at reducing puffiness. Products are best when used within six months to one year after opening. I was trying to decide between the Eye Serum and Eye Cream. Could you recommend which you think would be more beneficial for me? I am in my mid-30s and am starting to see some fine lines appearing around my eyes. I have 2 young children, and am pregnant with my third, so I am sleep-deprived most of the time with no end in sight. This unfortunately leaves me with some darkness under my eyes. Lastly, I am a contact lens wearer and have sensitive eyes if that makes any difference in your recommendation. I would recommend the Eye Serum for you. The botanical extracts really help to stimulate the circulation under the eyes and work wonders on puffiness and dark circles, while increasing cell turnover to help with the fine lines that are starting to appear. It is very lightweight and absorbs quickly and easily so it won’t cause any irritation to your sensitive eyes. What is the difference between the Kahina Serum and Kahina 100% Organic Argan Oil? Kahina Serum is a more complex product specifically formulated to heal and restore skin. Though based on argan oil, it also incorporates additional vitamin and antioxidant rich ingredients such as sea buckthorn and carrot seed oil, which are high in vitamins A and betacarotene, to strengthen the skin and protect against free radicals, slowing the aging process. The chamomile oil and bisabolol (derived from chamomile) are extremely soothing and act as anti-irritants for those with sensitive skin. Formulated to easily penetrate the skin for the successful delivery of its many ingredients and their benefits, Kahina Serum should be applied first, before a moisturizer, on clean dry skin so it can soak into the deepest layer of the epidermis. While the serum has many benefits for all skin types, it is ideally suited for a normal to dry skin type. The Kahina Argan Oil is pure, 100% organic argan oil that contains no other ingredients. It can effectively be used by anyone due to its simple ingredient list, as there is little room for sensitivities or reactions when all one is getting is a single pure organic and healing ingredient. Straightforward in form, Kahina Argan Oil use is not limited to just the face, and it can be used more liberally, especially on the hair or sprinkled in the bath. I have acne prone skin, what do you recommend? If you have acne prone skin you may want to use the Facial Lotion during the day and Argan Oil at night since both are lightweight and absorb well. How can I use Kahina Argan Oil in my hair? Argan Oil is an excellent conditioner for hair. It depends on your hair type whether or not you should leave it in or not. While argan oil is a lightweight oil, fine hair can appear greasy if oil is left in. For coarser dry hair, argan oil is a great way to tame the frizz. To condition and style damp or dry hair, apply 2-3 drops into the ends and work upwards, making sure to avoid applying at the hairline. To give you scalp and hair a deep moisturizing treatment, massage argan oil into scalp, leave for ten minutes, and wash as usual. Do Kahina products contain sunscreen? Our products do not contain added sunscreen. While sunscreen is essential in protecting against redness from the sun’s UVB rays and should certainly be used as part of safe sun practices, research suggests that photoprotection from topical antioxidants can boost the effectiveness of sunscreen to reduce signs of aging and protect against skin cancer caused by the sun’s UVA rays. In addition, vitamin E has proven to be effective at boosting UVB protection while vitamin C has strong protective effects against UVA radiation. Antioxidants also serve as topical anti-inflammatory agents, which are critical for healthy skin. We encourage the use of sunscreen in addition to our products. You can boosting your safe sun practices with the application of our antioxidant and Vitamin E rich Argan Oil and/or Serum and our antioxidant-rich and Vitamin C enhanced Eye Serum and Eye Cream.
