SALVIANOLIC ACID B.

Valuable CAS 121521-90-2 / SKIN CONDITIONING, SKIN PROTECTING

Salvianolic Acid B is a potent phenolic compound recognized for its multifaceted benefits, including robust antioxidant, anti-inflammatory, and regenerative properties. It offers promising potential for addressing photoaging, hyperpigmentation, wound healing, and improving overall skin health and hydration.

Antioxidant Anti-inflammatory Photoaging Protection Skin Brightening Wound Healing Support Collagen Production Enhancement (Type I & III) Hydration Anti-fibrotic

Science

Mechanism of Action

Salvianolic Acid B (Sal-B) functions primarily as a powerful antioxidant and anti-inflammatory agent. It combats photoaging by inhibiting harmful metalloproteinases (MMP-1) and pro-inflammatory cytokines like IL-6, while simultaneously boosting type I procollagen and TGF-β1 production. Sal-B protects cells from oxidative stress by promoting NRF2 nuclear translocation and mitigates UVB-induced damage through the MAPK and AP-1 pathways. Additionally, it targets hyperpigmentation by reducing tyrosinase activity and its related mRNA expression, thus inhibiting melanin synthesis. Its anti-fibrotic actions reduce collagen deposition, and it supports skin repair by enhancing cell migration and collagen type III expression, alongside increasing skin hydration.

Key findings

  1. 01 Increased cell viability, significantly stimulated cell migration, and elevated collagen type III expression, aiding wound healing in human gingival fibroblasts.
  2. 02 Inhibited tyrosinase activity and reduced mRNA expression of tyrosinase-related proteins, consequently decreasing melanin synthesis in co-cultured human melanoma and keratinocyte cells, indicating skin brightening potential.
  3. 03 In a mouse model of psoriasis-like dermatitis, it alleviated disease severity, reduced acanthosis, inhibited IL-23/IL-17 cytokines, and increased skin hydration.
  4. 04 Protected normal human dermal fibroblasts against UVB irradiation-induced photoaging, suppressing MMP-1 and IL-6 expression while promoting type I procollagen and TGF-β1 production.
