Stevia Rebaudiana Leaf/Stem Extract

Stevia rebaudiana leaf and stem extract is derived from the stevia plant, native to South America. It contains steviol glycosides, which are intensely sweet compounds extracted from the plant material. In skincare formulations, stevia is used almost exclusively as a masking agent rather than for direct skin benefits.The extract works by suppressing or offsetting unpleasant tastes in formulations—particularly relevant in products designed to be ingested or products containing active ingredients with bitter or unpalatable flavours. Its use in topical skincare is limited and typically appears …

Stevia's sweet taste profile works through interaction with taste receptors, allowing formulators to balance flavours in products designed to be consumed or tasted. The compound binds to sweet taste receptors on the tongue, creating a sweet sensation that can mask or reduce the perception of bitter or unpalatable ingredients.In topical skincare applications, stevia does not significantly penetrate the skin barrier and is not thought to exert direct pharmacological effects on skin tissue itself.

Stevia appears in very few skincare products and is not typically a key ingredient to select for. If present in a formulation you are using, it will be present in minimal amounts and does not require special application guidance. Continue using the product according to the manufacturer's instructions.

Stevia rebaudiana extract is generally recognised as safe for topical use and is approved for use in cosmetics in most regions. No significant adverse effects are documented for this ingredient at concentrations used in skincare formulations.
