Psoriasis is a chronic autoimmune skin condition characterized by the rapid buildup of skin cells, resulting in thick, red, scaly patches on the skin’s surface. While medical treatments focus on controlling underlying inflammation, many people seek topical remedies to manage associated symptoms of dryness and scaling. Coconut oil, a readily available natural product, has emerged as a popular choice for its ability to soothe irritated skin and provide intense moisture. This article investigates the scientific basis, dermatological consensus, and practical considerations for using coconut oil as an adjunct therapy for psoriasis.
How Coconut Oil Interacts with Psoriasis Symptoms
The theoretical benefit of coconut oil for psoriatic skin largely stems from its composition as an occlusive moisturizer. Its high-fat content, composed primarily of medium-chain triglycerides (MCTs), forms a physical barrier on the skin’s surface. This barrier significantly reduces transepidermal water loss (TEWL), locking in existing moisture to combat the extreme dryness and scaling typical of psoriasis plaques. By softening the hardened scales, the oil can also potentially help prescribed topical medications better penetrate the affected skin.
One of the most abundant MCTs in coconut oil is lauric acid (45–50% of its fatty acid profile). Lauric acid, and its derivative monolaurin, possess antimicrobial properties that may help prevent secondary infections, which can occur when psoriatic plaques crack or become irritated. Limited studies suggest that coconut oil also has anti-inflammatory properties, potentially by suppressing inflammatory markers in the skin. This effect could help soothe the redness and irritation associated with the condition.
Clinical Evidence and Dermatological Consensus
Scientific research directly examining coconut oil as a primary treatment for psoriasis is currently limited, with a lack of large, randomized controlled trials. The available evidence largely points to its efficacy as an excellent emollient, a substance that softens and soothes the skin. Studies on similar chronic dry skin conditions, such as eczema, have shown that virgin coconut oil can strengthen the skin barrier and improve hydration, suggesting a plausible benefit for psoriasis symptoms.
The consensus among dermatologists is that coconut oil should be considered an adjunct or complementary therapy, not a replacement for prescription treatments. While highly effective at moisturizing and relieving the discomfort of dry, scaly skin, there is no direct evidence that it can stop the underlying autoimmune process or significantly reduce plaque thickness. Prescription treatments, such as topical corticosteroids and vitamin D analogs, remain the established standard for controlling excessive skin cell growth and systemic inflammation. Coconut oil is best utilized to manage symptoms like flaking, itching, and dryness, improving the patient’s comfort and quality of life.
Guidelines for Topical Application
Users should generally choose virgin or unrefined coconut oil over the refined variety. Unrefined oil is processed without high heat, allowing it to retain more beneficial fatty acids, antioxidants, and anti-inflammatory compounds. Refined coconut oil, which is often bleached and deodorized, has fewer dermatological benefits, making the virgin form the preferred choice for sensitive skin conditions.
The oil is often solid at room temperature, so a small amount should be warmed between the palms before applying. Application is most effective when the skin is slightly damp, such as immediately after a bath or shower, to maximize moisture retention. Gently massaging a thin layer into the affected areas helps seal in the water and soften scales. For scalp psoriasis, the oil can be massaged into the scalp, left on for 30 to 60 minutes, or even overnight to help loosen thick flakes before shampooing.
Safety Considerations and Potential Side Effects
While generally considered safe for topical use, there are a few safety considerations for those with psoriasis. Coconut oil is highly comedogenic, meaning it tends to clog pores, particularly in individuals prone to acne or folliculitis. Although this is less of a concern on thick psoriasis plaques, it is advisable to use it sparingly on the face or areas prone to breakouts.
Applying any oil to severely inflamed, weeping, or broken skin should be approached with caution. Although rare, some individuals may experience irritant dermatitis or an allergic reaction to coconut products, which can worsen symptoms. Before using coconut oil widely, apply a small amount to an unaffected patch of skin for 24 hours to check for any adverse reaction. If irritation, redness, or itching increases, discontinue use of the product.
