Tephrosia seed oil

INCI: Tephrosia Purpurea Seed Oil

Tephrosia seed oil, Neurocosmetic vegetable oil

In brief

  • What is it: An oil obtained by pressing the seeds of Tephrosia purpurea: the oil-soluble fraction of a neurocosmetic active ingredient.
  • What it does: It acts on cortisol produced by the skin during prolonged periods of stress and supports beta-endorphins associated with comfort.
  • Where to find it: In anhydrous formulas, such as the oil scrub in the body care line.

What is Tephrosia seed oil

L'Tephrosia purpurea seed oil is obtained by pressing the seeds of the Indian legume. It belongs to the family of neurocosmetic actives and is the oil-based counterpart to the extract: same plant, same part, but a fat-soluble rather than water-soluble fraction.

Why an oil-based form is needed

The distinction is not merely formal. An anhydrous formula such as an oil scrub cannot incorporate a water-based extract: the active ingredient needs to be in oil-based form. This is why the body line uses the extract in the cream and shower gel, and the seed oil in the massage oil and scrub.

How it acts on stressed skin

L'goal remains the same: to act on the cortisol the skin produces during periods of prolonged stress, and support beta-endorphins associated with a feeling of comfort. In a scrub, this complements the exfoliation process, which becomes the moment when the treatment begins.

What to know about efficacy data

The efficacy data circulating about this active ingredient come from the manufacturer's tests, not independent studies, and should be taken as indicative. A cosmetic improves the appearance of the skin and user comfort: it does not treat dermatological conditions or replace stress management.

Frequently asked questions

What’s the difference between Tephrosia oil and extract?

They come from the same plant and the same part, but the oil is the fat-soluble fraction and the extract is the water-soluble one. The body care line uses the extract in the cream and shower gel, and in the massage oil, and the seed oil in the scrub.

Why is Tephrosia oil used in scrubs?

An oil-based scrub is an anhydrous formula and cannot accommodate an extract in an aqueous phase: the oil-based form is needed for the active ingredient to be incorporated.

Does LTephrosia oil help stressed skin?

It works on cortisol produced by the skin and on skin comfort, and in the scrub, it complements the exfoliating action. A cosmetic product improves the skin's appearance and comfort, but does not replace stress management.
