Lens Esculenta Fruit Extract

Lens esculenta (lentil) fruit extract is typically used as a conditioning/antioxidant or soothing botanical at low concentrations (often <1–3%) and is generally well-tolerated in standard patch-testing experience for plant extracts. However, as a legume-derived botanical containing proteins and other bioactives, it carries a small but real risk of irritation or sensitization in highly reactive or eczematous skin, especially when layered with other actives. Given this non-zero sensitization potential despite its “gentle” positioning, a gentle-but-not-inert score is most appropriate. Safety Notes: In commercial skincare, lentil (Lens esculenta) fruit extract is most often used as a minor botanical/antioxidant or skin-conditioning component at very low levels (trace to ~0.1%), especially in multi-extract blends in leave-on serums/creams and in rinse-off cleansers where it is typically kept low for cost and clarity/stability. Higher-strength consumer products marketed for pore appearance, oil control, or firming commonly use 0.5–2% (often depending on extract standardization and carrier), and the upper end around ~5% is seen in “booster” style leave-on formulations or heavily botanically-loaded products where the extract is a primary featured active. There are no specific EU/FDA maximum concentration limits for this botanical; practical constraints (solvent system, odor/color, and viscosity/clarity) usually set the upper bound rather than regulation.
