What Is Glycine Max (Soybean) Oil?

Glycine max (soybean) oil is the oil extracted from domesticated soybeans, as opposed to wild soybean (Glycine soja). Though there are some genetic differences between the two varieties, Glycine max oil shares many of the same benefits of Glycine soja oil.\n\nIn addition to the antioxidant properties most plant oils have, Glycine max oil contains fatty acids – among the linoleic, oleic, and linolenic acids – which help restore skin’s natural moisturizing factor and shore up its barrier.\n\nThe independent Cosmetic Ingredient Review panel has deemed several components of the Glycine max (soybean) plant safe as used in cosmetics, as well as the oil of the related Glycine soja, though it has not ruled specifically on Glycine max oil yet.

How It Works

Glycine Max Oil works primarily as an occlusive and emollient. Its fatty acid composition allows it to sit on the skin surface and reduce transepidermal water loss, thereby helping skin retain its natural moisture. This creates a smoother, softer appearance.

Plant oils in general are recognised for their ability to support skin conditioning through their natural lipid content, which mimics some of the skin's own sebaceous secretions. This can be particularly beneficial for skin that feels dry or compromised.

How to Use

Glycine Max Oil is typically used as part of a complete skincare routine rather than in isolation. It works well when layered into serums, moisturisers, or facial oils. Apply to clean, slightly damp skin for optimal absorption. A little goes a long way, so start with a small amount and adjust based on your skin's response.

Safety & Precautions

Generally well-tolerated by most skin types. Those with soy allergies should avoid products containing soybean oil, as cross-reactivity is theoretically possible, though clinical evidence suggests this is rare.
