Argan oil has some properties that support skin healing, but the evidence for it reducing visible scars is limited. It’s rich in fatty acids and vitamin E, which help keep skin moisturized and may improve elasticity over time. However, dermatologists note that argan oil alone is unlikely to make a significant difference for established scars like acne scars or stretch marks.
What Argan Oil Actually Does for Skin
Argan oil’s potential benefits come from its chemical makeup. It contains 43 to 49% oleic acid and 29 to 37% linoleic acid, two fatty acids that help reinforce the skin’s moisture barrier. It also packs 60 to 90 mg of tocopherols (vitamin E compounds) per 100 grams, with gamma-tocopherol making up the largest share. Vitamin E is an antioxidant that protects skin cells from damage during healing and helps reduce inflammation.
The oil also contains squalene, a compound your skin naturally produces to stay hydrated. Together, these ingredients make argan oil effective at softening and moisturizing skin. That’s useful for scar tissue, which tends to be drier and less flexible than surrounding skin. Keeping a scar well-hydrated can make it look smoother and feel less tight, even if the scar itself doesn’t shrink.
The Gap Between Hydration and Scar Removal
There’s an important distinction between improving how a scar feels and actually remodeling scar tissue. Argan oil does the first thing well. A study published in Clinical Interventions in Aging found that topical argan oil application over 60 days significantly improved skin elasticity across multiple measures, making skin more supple and resilient. But improved elasticity in healthy skin isn’t the same as flattening a raised scar or filling in a depressed one.
Dr. Shilpi Khetarpal at Cleveland Clinic has noted that while argan oil can add a hydration boost, it won’t have much effect on things like acne scars or stretch marks. Scars involve structural changes in collagen, and no topical oil can reorganize collagen fibers the way laser treatments or microneedling can. If you’re dealing with deep or textured scarring, argan oil shouldn’t be your primary strategy.
Where Argan Oil May Help Most
Argan oil is better suited for newer, milder scars that are still in the remodeling phase. It has anti-inflammatory properties that may support healing of minor wounds, burns, and scrapes. By keeping the area moisturized during healing, you reduce the chance of the scar becoming excessively dry, raised, or itchy.
For flat, discolored scars (like the dark marks left behind after a pimple heals), consistent moisturizing with argan oil may help the skin turn over faster and fade discoloration gradually. The vitamin E content offers some protection against UV-related darkening of scar tissue, though it’s no substitute for sunscreen, which is the single most effective way to prevent scars from becoming more visible.
One study on a topical oil formulation containing plant extracts and vitamins found a 71% clinical improvement in the appearance of stretch marks. But that formulation combined multiple active ingredients, so it’s impossible to credit argan oil alone for the result. This pattern shows up repeatedly in the research: argan oil appears in effective blends, but standalone evidence for scar reduction is thin.
How to Apply It
If you want to try argan oil on a scar, wait until the wound is fully closed. Applying oil to an open wound can trap bacteria and slow healing. Once the skin has sealed, you can begin using it.
Scar massage is the most effective way to apply any topical product to scar tissue. Place a few drops of argan oil on the scar and use your fingertips to massage in small circular motions, applying moderate pressure. General guidance from scar rehabilitation specialists recommends massaging for at least 10 minutes, twice a day, for up to six months. The massage itself matters as much as the oil: it helps break up adhesions in the tissue beneath the scar, improves blood flow, and keeps the area flexible.
Pure, cold-pressed argan oil works best. Blends with added fragrances or other ingredients introduce variables that could irritate healing skin. Argan oil has a comedogenic rating of 0 on a scale of 0 to 5, meaning it’s extremely unlikely to clog pores. That makes it a reasonable option even for people with acne-prone skin who are treating post-acne marks.
Realistic Expectations
Argan oil can soften scar tissue, improve moisture, and potentially help fade mild discoloration over weeks to months of consistent use. It won’t erase scars, flatten keloids, or fill in pitted acne scars. For those concerns, treatments like silicone sheets (for raised scars), retinoids (for texture and pigment), or in-office procedures like laser resurfacing are better supported by evidence.
That said, argan oil is inexpensive, gentle, and unlikely to cause irritation. Using it as part of a daily scar massage routine costs you nothing beyond time, and the moisturizing benefits are real. Think of it as a supporting player rather than a solution on its own.
