Vegetable Oil

Vegetable oil is a lipid extracted from plant sources—seeds, nuts, or fruits—and refined for use in skincare and haircare formulations. It functions as an emollient and occlusive, meaning it both softens the skin surface and helps seal in moisture by forming a protective barrier.The composition varies depending on the source plant, but vegetable oils typically contain triglycerides and fatty acids that mimic the skin's own lipid profile, making them well-suited to barrier support and conditioning.

Vegetable oils work primarily through occlusion and emollient action. When applied to skin, they form a hydrophobic layer that slows water evaporation from the epidermis, helping to maintain hydration levels. This is particularly useful for dry or compromised skin barriers.The fatty acids in vegetable oils are also small enough to penetrate the outer layers of skin, where they can help restore lipid balance and improve the skin's texture and flexibility.

Vegetable oils work best when applied to damp skin to lock in moisture. Use sparingly on oily or acne-prone skin, as heavier oils may feel occlusive or potentially feed certain microorganisms. For dry skin, apply after water-based products to maximise hydration. Always patch-test first, particularly if your skin is reactive, as some individuals may find certain plant oils sensitising.

Vegetable oils are generally well-tolerated, though individual sensitivities vary by plant source. Some users report that certain oils may exacerbate fungal acne; if this is a concern for you, consider avoiding heavier oils and opting for lighter plant alternatives.
