Mechanism of Action
This extract primarily functions by conditioning the skin, fostering a soft, smooth, and hydrated feel. Its rich composition of inulin, vitamins, minerals, and antioxidants contributes to its efficacy. Inulin, a prebiotic polysaccharide, supports a healthy skin microbiome and forms protective films. The extract exhibits significant anti-inflammatory actions by attenuating atopic dermatitis symptoms, reducing inflammatory mediators, decreasing epidermal thickness, and inhibiting mast cell infiltration. It actively restores filaggrin expression, a critical protein for robust skin barrier function, and impedes adhesion molecules involved in inflammatory responses. Furthermore, it suppresses key inflammatory signaling pathways, including NF-κB, Akt, and MAPK, in human keratinocytes. Bioactive compounds like phenolic acids, coumarins, flavonoids, and fatty acids lend additional antioxidant, antimicrobial, and anti-inflammatory attributes.

Key findings
- 01 Topical application of Helianthus Tuberosus ethanol extract in murine models of atopic dermatitis significantly reduced dermatitis scores and inflammatory mediators. The treatment notably decreased epidermal thickness, minimized mast cell infiltration, restored critical filaggrin expression, and inhibited adhesion molecules. In human keratinocytes, the extract demonstrated an ability to suppress NF-κB, Akt, and MAPK signaling pathways, confirming its anti-inflammatory and skin barrier improvement potential.
- 02 Further studies in mice with atopic dermatitis and HaCaT keratinocytes corroborated these findings, showing relief and attenuation of symptoms, a reduction in epidermal thickness, and enhanced filaggrin expression.
- 03 Inulin, a key component isolated from Helianthus tuberosus, has been effectively incorporated into cosmetic products, such as body wash gels, to mitigate skin irritation.

Stability
Extraction processes commonly utilize solvents such as water or alcohol, with hot water frequently employed for inulin isolation. Pretreatment of the Jerusalem artichoke in water at a neutral pH and 80°C for 2 minutes can effectively inhibit enzyme activity and prevent browning during processing.
Safety
Safety Profile
The CIR Expert Panel found insufficient data to fully assess the safety of ingredients derived from 'other plant parts' of Helianthus annuus (a category that includes Helianthus tuberosus tubers). While generally uncommon, isolated instances of skin irritation, allergic reactions, redness, or itching have been reported. A patch test is recommended prior to extensive use.
