What Is Hydrolyzed Borage Seed Oil?

Hydrolysed borage seed oil is borage oil that has been broken down into smaller molecular components through hydrolysis. This process makes the oil more easily absorbed by the skin and hair whilst maintaining the beneficial fatty acid profile of the original seed oil.

Borage seed oil is rich in gamma-linolenic acid (GLA), an omega-6 polyunsaturated fatty acid that plays a role in maintaining skin barrier function. The hydrolysed form allows these compounds to penetrate more effectively than standard borage oil.

How It Works

Hydrolysed borage seed oil works by depositing its fatty acids and other lipid components onto the skin and hair surface. These compounds form an occlusive layer that slows water evaporation, helping to lock in moisture.

The GLA and other polyunsaturated fatty acids in borage oil may also support the skin's barrier repair mechanisms at a deeper level, though the extent to which hydrolysed forms penetrate versus remain surface-bound varies depending on formulation and concentration.

Clinical Evidence & References

Research on borage seed oil and GLA shows promise for supporting barrier function and reducing transepidermal water loss, though most studies have focused on unhydrolysed forms or oral borage oil supplements. The hydrolysed variant is less extensively studied in isolation.

Evidence suggests hydrolysed oils can improve skin hydration and conditioning when used in formulations, but high-quality clinical trials specifically evaluating hydrolysed borage seed oil in cosmetic products remain limited. It appears well-tolerated in topical use.

How to Use

Hydrolysed borage seed oil works well in lightweight serums, moisturisers, and conditioners where it can be evenly distributed. It pairs well with other hydrating and barrier-supporting ingredients. Use daily as part of your moisturising routine, or as directed on the product label.

Safety & Precautions

Generally well-tolerated in cosmetic formulations. Those with known borage sensitivity should avoid. Can occasionally cause mild irritation in very sensitive skin, though this is uncommon.
