smooth texture, hydrate, and boost radiance with fermented ingredients
and ceramides for a healthy glow.Key Ingredients & Their Roles:

• Panthenol (Pro-Vitamin B5): Soothes and moisturizes the skin.
• Fermented Ingredients: Galactomyces Ferment Filtrate and Leuconostoc/Radish Root Ferment Filtrate offer nutrients and support skin health.
• Ceramides: High-density polymer ceramides help strengthen the skin's moisture barrier.
