What Is Solanum Lycopersicum Seed Oil?
Solanum lycopersicum seed oil is extracted from tomato seeds and belongs to the emollient category of skincare ingredients. It contains bioactive compounds including lycopene, flavonoids, and steroidal saponins such as lycoperoside H, which give it potential anti-inflammatory and antioxidant properties.
In formulations, this oil functions primarily as a skin conditioner and emollient, helping to soften and hydrate the skin barrier. It is relatively uncommon in commercial skincare products, appearing in roughly 0.1% of formulations.
How It Works
Tomato seed oil delivers its benefits through several active compounds. Lycoperoside H and flavonoids appear to inhibit human neutrophil elastase (HNE), an enzyme that becomes activated during inflammatory stress and can contribute to skin damage. By reducing HNE activity, these compounds may help protect skin structure and minimise inflammatory damage.
As an emollient, the oil itself creates a protective layer on the skin surface, helping to reduce water loss and maintain hydration. The combination of this occlusive function with the antioxidant and anti-inflammatory compounds makes it a multi-functional ingredient, though the extent of benefit depends on the concentration used and individual skin response.
Clinical Evidence & References
Research on tomato seed extract shows promising laboratory and animal model results. In vitro studies demonstrate that lycoperoside H and other flavonoids inhibit human neutrophil elastase, suggesting a mechanism for reducing inflammatory damage. Animal studies in atopic dermatitis models indicated that tomato seed extract and lycoperoside H both reduced inflammation markers and transepidermal water loss.
However, human clinical data on tomato seed oil applied topically is limited. The evidence available comes primarily from extract studies and animal models rather than large-scale human trials of the oil itself in finished products. More research would be needed to confirm efficacy at typical cosmetic concentrations and to establish optimal usage guidelines.

How to Use
Solanum lycopersicum seed oil works best as part of a layered skincare routine. Apply to clean, slightly damp skin before serums or heavier creams to optimise absorption. It can be used daily in moisturisers or oils, though individual tolerance should guide frequency. If using a product containing this oil for the first time, patch test first to ensure compatibility with your skin.
