Stevia Rebaudiana Leaf/Stem Powder

Stevia rebaudiana leaf and stem powder is a natural ingredient derived from the stevia plant, native to South America. It contains steviol glycosides—compounds that are significantly sweeter than sugar but calorie-free. In skincare formulations, stevia is primarily used as a skin conditioning agent rather than for sweetening.The powder form allows formulators to incorporate the ingredient's conditioning properties directly into products. It functions as a humectant and emollient, helping to support the skin's moisture retention and overall feel.

Stevia functions as a humectant, drawing moisture into the outer layers of the skin. The leaf and stem powder also acts as an emollient, creating a protective layer that helps reduce transepidermal water loss—the process by which water naturally evaporates from the skin.The antioxidant compounds present in stevia, particularly polyphenols, may help neutralise free radicals generated by UV exposure and environmental pollution, though the extent of this benefit in topical products requires further research.

Stevia powder can be found in cleansers, toners, hydrating serums, and moisturisers. Because it is a mild ingredient, it can be used daily as part of a regular skincare routine. If using a product containing stevia, integrate it into your existing regimen based on the product format—for example, a stevia-containing moisturiser would replace your current moisturiser rather than add another step.

Stevia rebaudiana is generally well-tolerated and considered safe for topical use on all skin types. No significant adverse effects have been reported in cosmetic applications, though patch testing is sensible if you have known sensitivities to botanical extracts.
