Science
Mechanism of Action
Operating as a powerful humectant, Sodium Malate effectively binds water molecules, significantly enhancing skin hydration and preventing transepidermal moisture loss, which contributes to a smoother, softer complexion. Beyond its moisturizing capabilities, it meticulously helps maintain the optimal pH balance within cosmetic formulations and on the skin. This ingredient is also suggested to bolster the skin's natural anti-aging defenses by supporting the synthesis of critical structural elements like hyaluronic acid, collagen, and elastin, which can diminish the appearance of wrinkles. Its strong antioxidant profile actively neutralizes free radicals, safeguarding skin youthfulness and elasticity. Additionally, Sodium Malate can optimize the absorption of other active ingredients, functioning as a gentle peeling agent to rejuvenate the skin's surface.
