The firming complex is a glycolic extract that combines two plant-based ingredients: the fruit of the Kigelia africana, the sausage tree, and the bark of Quillaja saponaria, the Chilean soapbark tree. It belongs to the family of tensor actives, the only ones that produce a noticeable result within a few minutes.
Tensor actives work on the surface of the skin, not on its structure: they smooth the texture and make the light more even, with a result that is visible in the mirror almost immediately. Quillaja is rich in saponins, while Kigelia provides flavonoids — the extract is standardized specifically for their content — with an antioxidant contribution that complements the immediate effect.
It is used when you need a result within the day: tired-looking features, skin that has lost definition, or an occasion when you want to look rested. The ingredient's technical documentation indicates an immediate lifting effect that lasts for several hours, accompanied by improvements in the smoothness and hydration of the superficial layers.
It is an active ingredient that works on a level complementary to that of foundational actives: while peptides and antioxidants build results over weeks, the tensor complex provides the immediate payoff that makes using the product every day enjoyable. In a well-designed formula, the two time scales coexist, and that is what makes the difference between a cream you finish and one that remains in the drawer. It is also Ecocert-approved according to the Cosmos standard.
