Ellagic Acid, Natural Whitening Ingredient(CAS 476-66-4)
Cosmetic Grade Ellagic Acid is a high-purity natural plant-derived multifunctional whitening and antioxidant active ingredient, refined and purified from natural plant tissues such as pomegranate rind and gallnut.
As a classic mild and efficient whitening raw material in high-end skincare, it has a unique triple skin care mechanism of melanin inhibition + free radical scavenging + anti-inflammatory repair. Different from ordinary whitening ingredients that only inhibit tyrosinase, Ellagic Acid can act on the whole melanin production chain: it not only effectively inhibit tyrosinase activity to block melanin synthesis from the source, but also prevent the transfer and deposition of formed melanin, and gradually metabolize accumulated pigmentation.
It has a significant fading effect on stubborn chloasma, sunburn spots, inflammatory acne marks and long-term dull yellow skin. In terms of anti-aging protection, EA has excellent natural antioxidant capacity, which can efficiently scavenge excess free radicals generated by ultraviolet radiation and environmental pollution, reduce skin oxidative damage, delay light aging and dry aging, and improve rough and dull skin texture.
Meanwhile, its mild anti-inflammatory effect can relieve skin inflammatory reactions caused by sun exposure and acne inflammation, soothe redness and swelling, reduce post-inflammatory pigmentation, and avoid dullness and color sinking caused by skin inflammation. With stable molecular activity, mild and non-irritating properties, good skin compatibility and no photosensitivity, it is a safe and efficient all-round whitening and repairing raw material, widely used in medium and high-end functional skincare products.
