Valuable CAS 90131-63-8 (generic) / SKIN CONDITIONING

Solanum Lycopersicum Leaf Extract, derived from tomato leaves, is a potent botanical ingredient renowned for its multifaceted benefits in skincare. It offers powerful antioxidant protection against environmental damage while actively combating visible signs of aging by stimulating collagen and elastin production. The extract also contributes to skin refinement through its astringent properties, helping to balance sebum and promote a clearer, more even complexion.

Science

Mechanism of Action

This extract acts as a robust antioxidant, effectively scavenging free radicals that accelerate skin aging, thereby preventing collagen degradation and diminishing inflammation, fine lines, and wrinkles. It exhibits astringent qualities, which aid in minimizing pore appearance and regulating excess oil secretion and associated redness. Furthermore, Solanum Lycopersicum Leaf Extract provides protection against environmental aggressors like radiation and pollution, promotes skin brightening for a more uniform tone, and stimulates the synthesis of collagen and elastin to enhance skin elasticity and firmness, fortifying the extracellular matrix. Its soothing and anti-inflammatory attributes reduce redness and irritation, while its mineral and amino acid content delivers moisturizing effects to maintain skin hydration. The extract also harmonizes sebum production and supports the gentle removal of dead skin cells.

Stability

Solanum Lycopersicum Leaf Extract generally exhibits good physical stability in cosmetic formulations when properly integrated, with lotions maintaining stability for a minimum of 28 days. However, formulation stability can be influenced by factors such as surfactant concentration, which has been observed to impact toner formulations. Increased concentrations of the extract may lead to a decrease in viscosity. Lycopene, a key component within tomato extracts, is oil-soluble and may show temperature-sensitive stability in cream bases.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) has not specifically reviewed Solanum Lycopersicum Leaf Extract. However, the broader Solanum Lycopersicum Fruit Extract is widely considered safe for topical application at appropriate concentrations. While individual sensitivities are possible, a serum containing 0.10% tomato extract demonstrated no irritation in voluntary assessments. It is important to differentiate typical leaf extracts from highly concentrated forms; for instance, a natural tomato oleoresin extract (NTOE) at 5% in petroleum jelly was found to be a moderate eye irritant and sensitizer in animal models, though it lacked dermal irritation. This concentrated form may not be representative of general leaf extracts.
