What Is Citrullus Lanatus Fruit Water?
Citrullus lanatus fruit water is the liquid extract obtained from watermelon fruit. It contains naturally occurring amino acids, vitamins and minerals that watermelon accumulates as it grows. In skincare formulations, this ingredient functions primarily as a humectant and skin conditioning agent.
The extract is valued in cosmetic formulations for its lightweight hydrating properties and its composition of compounds that support skin moisture retention without a heavy feel on the skin.
How It Works
Watermelon fruit water works primarily through its humectant action. Humectants are molecules that pull water from the air and deeper skin layers into the outer layer of the epidermis, increasing hydration and plumpness. This mechanism helps skin feel and appear more supple.
The ingredient also contains amino acids and other skin-conditioning compounds that support the skin's natural moisturisation processes and may help reinforce skin texture.
Clinical Evidence & References
Research specifically examining citrullus lanatus fruit water in skincare is limited. Most supporting evidence comes from the ingredient's traditional use and the known hydrating properties of watermelon's constituent compounds rather than dedicated clinical trials on the extract itself.
Watermelon contains citrulline and other amino acids that have been studied in isolation for various skin benefits, but evidence for the fruit water extract as a whole in cosmetic formulations would benefit from additional clinical investigation.
How to Use
Citrullus lanatus fruit water is typically used in serums, toners, hydrating mists and lightweight moisturisers. It works well layered with other hydrating ingredients and can be used daily as part of your skincare routine. For best results, apply to damp skin to enhance the humectant effect.
