Science

Mechanism of Action

This ingredient is rich in essential vitamins (C, A, B), potent antioxidants, and flavonoids, which collectively combat free radicals and protect the skin from environmental stressors, thus mitigating premature aging signs such as fine lines and wrinkles. Its significant vitamin C content actively promotes collagen synthesis, leading to improved skin firmness and elasticity. Furthermore, it aids in complexion brightening and reduction of hyperpigmentation by inhibiting the tyrosinase enzyme. Psidium Guajava Fruit Juice also provides deep moisturization through natural emollients, locking in vital hydration. Its inherent antiseptic, antibacterial, and anti-inflammatory properties make it particularly effective for managing blemish-prone skin, calming irritation, and reducing redness. It contributes to balanced oil production, minimizes pore congestion, and supports skin cell regeneration for a refined texture.
