L'Tephrosia purpurea seed extract is obtained from a legume widespread in India. It belongs to the family of neurocosmetic actives neurocosmetics, the field that studies the dialogue between the nervous system and the skin and is among the most promising areas of contemporary dermocosmetic research.
The discovery behind it is this: the skin has its own stress-response system, independent of the central one. Under prolonged pressure, keratinocytes produce cortisol locally, which is why during difficult periods the complexion appears dull and the barrier becomes more fragile. The active works on the enzyme that generates this skin cortisol, with a parallel increase in beta-endorphins, the mediators linked to a sense of well-being.
It is designed for skin that is affected by periods of stress: a tired appearance, uneven complexion, and a feeling of tightness. The first changes can be observed after three to four weeks of consistent use.
In LeLang formulas, it is at the heart of the neurocosmetic body-care line, where the application ritual itself — the massage and the time devoted to oneself — works in the same direction as the active ingredient. It is one of the few cosmetic ingredients to have originated from a neurophysiological hypothesis, making it interesting beyond the immediate result.
