Summary

Skin-conditioning agent Humectant Antioxidant Soothing Anti-inflammatory Hydrating Mild Exfoliant Barrier Support

Science

Mechanism of Action

Malva Sylvestris extract exerts its anti-inflammatory effects through mucilages, anthocyanosides, and tannins, effectively reducing redness, swelling, and irritation. Its rich content of mucilages and polysaccharides provides powerful moisturizing and hydrating action by forming a protective film that minimizes transepidermal water loss (TEWL). Antioxidant activity is attributed to anthocyanosides and vitamins A, C, and E, which neutralize free radicals. Additionally, tannins within the extract may contribute to mild exfoliation, assisting in the detachment of dead skin cells and refining the appearance of pores. The ingredient also supports natural skin regeneration, enhances circulation, and offers anti-itch and anti-irritation benefits.
