Both are anti-irritants working through different mechanisms. Bisabolol inhibits COX-2 while allantoin promotes cell proliferation and wound healing.
Both promote wound healing: centella stimulates collagen synthesis, allantoin promotes cell proliferation. Fast recovery combination.
Allantoin soothes and promotes cell regeneration, reducing retinol-induced irritation while supporting the cell-turnover process.
Allantoin promotes epithelial regeneration while HA provides the hydrated environment needed for optimal cell migration and repair.
