Citrus Limon Fiber

Citrus Limon Fiber is typically used at low percentages as a plant-derived bulking/texture and absorbent material (often from lemon peel/pulp), and while it is not an acid or exfoliant, citrus-derived botanical materials can contain residual proteins, sugars, and trace aromatic components that increase the chance of stinging or eczematous flares in highly reactive skin. Patch-test and clinical experience with botanical fibers support overall low-to-moderate irritancy, but in compromised barriers (eczema/post-procedure) the risk of irritation or sensitization is not negligible, so I rate it as mild. Safety Notes: Citrus Limon (lemon) fiber is typically used as a natural texturizer/absorbent and ‘biobased’ structuring aid; in many leave-on creams/lotions and serums it appears at very low levels (~0.05–0.5%) as part of a broader rheology/feel system. Higher-load consumer products (especially natural/deodorant creams, cleansing pastes, clay/mud masks, and some solid or balm-like formulas) can use ~1–5% to build viscosity, reduce oiliness, and improve sensory/structure. Use above ~5% is uncommon in mainstream OTC skincare due to grit/pilling risk and texture constraints rather than regulatory limits.
