Sennoside and antioxidant acid complexes: LorealRecent Research Landscape

Chemical instability and poor deposition of active botanicals lead to reduced efficacy in topical formulations. This lever utilizes ionic charge pairing to stabilize sennosides and ensure targeted delivery to the substrate.

What technical problems is Loreal addressing in Sennoside and antioxidant acid complexes?

Active ingredient chemical instability

(27)evidences

High concentrations of ascorbic acid are chemically unstable and prone to rapid oxidation when exposed to light or aqueous environments. Preventing this breakdown maintains the potency and shelf life of the topical formulation.

Cutaneous structural degradation

(27)evidences

Accumulation of advanced glycation end-products leads to loss of skin elasticity and structural integrity. Preventing this biochemical breakdown preserves tissue resilience and aesthetic appearance.

Retinoid chemical instability

(12)evidences

High concentrations of retinol and other sensitive bioactives are prone to rapid loss of potency when exposed to environmental factors. Preventing this breakdown ensures long-term product efficacy and shelf-life stability.

Epidermal barrier dysfunction

(8)evidences

Unregulated melanogenesis leads to hyperpigmentation and uneven skin tone. Mitigating this biological overactivity provides a localized aesthetic and dermatological corrective effect.
