Science

Mechanism of Action

Indigofera Tinctoria Extract fosters healthy skin equilibrium by calming inflammation and alleviating redness. Its rich antioxidant profile, attributed to compounds such as bioflavonoids, indirubin, and tryptanthrin, actively neutralizes harmful free radicals, mitigating oxidative stress and premature aging. The extract strengthens the skin barrier through enhanced filaggrin production, a crucial protein for skin structure, thereby minimizing transepidermal water loss (TEWL) and bolstering defense against environmental aggressors. Furthermore, its anti-inflammatory properties contribute to wound healing by reducing dermal inflammation and boosting antioxidant enzyme activity. Emerging research also suggests antimicrobial, anti-acne, and skin brightening effects.

Stability

This extract exhibits low stability when exposed to light and elevated temperatures, which can limit its application, particularly concerning its natural color. Degradation of the colorant can occur at moderate temperatures, such as 40°C. For optimal color preservation, the pH of the formulation should be maintained within the alkaline range of 8 to 14.
