I've Relied on This Dermatologist-Approved Argan Oil for Glowy Skin and Fewer Wrinkles for Years

Argan oil might just be my best kept beauty secret—it certainly lives up to its renowned nickname, "liquid gold." I've been using it as a facial moisturizer, hair serum, and cuticle conditioner for more than five years, and it has helped reduce wrinkles, maintain smooth and radiant skin, combat frizz on my chemically treated hair, and keep my cuticles moisturized and manageable. But don't just take my word for it—scientific studies, along with dermatologists, describe it as an anti-wrinkle powerhouse and superstar moisturizer.

While there are plenty of argan oil choices out there, my go-to is Josie Maran 100% Pure Argan Oil. It's made with a single ingredient, argan oil, which comes from argan tree nuts that are sustainably harvested by Indigenous women groups in a UNESCO-protected forest in Morocco. The kernels are then processed by hand and cold-pressed to help the oil retain all its fatty acids and antioxidants to benefit skin, hair, and nails.

The best news? Luxury skin oils with anti-aging properties typically come with a high price tag to match, but you can score my must-have argan oil right now for up to 20% off with code savespring during Sephora's VIB sale.

Rich in vitamins A and E, antioxidants, and omega 3, 6, and 9 fatty acids, argan oil is especially effective in firming skin and improving elasticity, minimizing fine lines and wrinkles, increasing hydration, and offering protection from free radical damage. "Topical argan oil has been shown to help improve skin elasticities and hydration, so it definitely can be described as a anti-aging, anti-wrinkle, and skin-improving ingredient," Rachel Nazarian, MD, a New York-based dermatologist and fellow of the American Academy of Dermatology, tells Health. Dr. Nazarian also says that argan oil is a "superior choice when compared to other oils used in skincare."

The benefits of argan oil don't stop at skincare. When applied to hair, argan oil is quickly absorbed by the hair shaft and seals the strand's cuticle, making it an effective repair therapy for color-treated and damaged hair, according to research. And when used on nails over time, argan oil moisturizes and strengthens cuticles with just a few drops.

I moisturize my face with Josie Maran's argan oil every night. I just warm a few drops of oil in my hands before gently applying to my cleansed face in an upward, circular motion. The oil works as a deep moisturizer, and there's no need for additional serums or creams. With my sensitive skin, I often find that heavier oils and moisturizers cause breakouts or allergic reactions, but this one is very light, doesn't clog my pores, and absorbs super quickly, so it doesn't leave me feeling greasy. After a couple of months of nightly applications, I noticed that my skin felt smoother—and with continued use, my fine lines disappeared, and I have even avoided developing wrinkles around my eyes and mouth.

Thanks to its multitasking abilities, this argan oil also acts as a serum on dry hair to prevent frizz, tame flyaways, and strengthen my ends—giving my hair a healthier appearance between salon visits. After blow drying, I apply a few drops to my hands, rub them together, and run my fingers through my hair, starting at the ends. I finish by smoothing out stubborn flyaways for a more polished look.

When caring for my nails, I swipe a tiny amount of oil over my cuticles and give it a few minutes to absorb. By the time I'm ready to push my cuticles down, they're perfectly moisturized and manageable, and this step helps to minimize pain during maintenance.

If you need further proof that this argan oil deserves a spot in your beauty routine, consider all the rave reviews by Sephora shoppers: More than 131,000 customers have given the product a "heart." It's also earned more than 5,000 five-star ratings, with shoppers reporting that it locks in moisture, minimizes wrinkles, helps fade acne scars and dark spots, fights blemishes, and leaves you with a dewy glow. Users who used it on their hair also noted that their tresses have never looked so good, and others shared that it even boosts brow growth.

Reviewers call it "life changing" and claim that their skin "has never been consistently better," adding that it makes it smooth and the perfect texture. A shopper who describes her skin as "mature" and has been using the product for years says, "It plumps up my skin, and when I use it at night, the next morning my skin looks hydrated." Another, who's been using it as an "eye cream" for years, revealed that it "works well under eyes for reducing fine lines and wrinkles."
