Citrus Medica Limonum Fruit Extract

Citrus Medica Limonum Fruit Extract is derived from the lemon fruit and contains naturally occurring acids, vitamin C precursors, and polyphenols. It functions primarily as a skin conditioning agent and fragrance component in skincare formulations.The extract is used in small concentrations—typically well under 1%—where its conditioning properties are valued rather than its exfoliating potential. This distinguishes it from concentrated lemon juice or isolated citric acid, which carry a higher risk of irritation at meaningful doses.

The extract conditions skin primarily through its natural humectant and emollient compounds, which help the outer layers of skin retain moisture. The polyphenols it contains act as antioxidants, neutralising free radicals that can contribute to skin damage.At the low concentrations used in cosmetics, any exfoliating or depigmenting effects from citric acid are negligible. Instead, the ingredient's role is gentle conditioning and sensory contribution rather than active treatment.

This ingredient is typically incorporated into serums, toners, and lightweight moisturisers where its conditioning and fragrance benefits complement other actives. Because it appears in very low concentrations, it need not be a deciding factor when selecting a product—focus instead on the formula's primary active ingredients and your skin's needs. Use products containing it as directed, usually once or twice daily depending on the formulation.

Generally well-tolerated in the concentrations used in skincare products. Individuals with citrus sensitivity or fragrance sensitivity should patch-test first, though reactions are uncommon at these dilution levels.
