How Cinnamic Acid Lightens Skin?
There are many benefits of cinnamic acid for the skin. Primarily, its skin-lightening effect is attributed to its ability to:
Tyrosinase Inhibitor for skin
Tyrosinase is a melanin-producing component that gives the skin its colour. Cinnamic acid is known to inhibit this enzyme, leading to reduced melanin synthesis. By slowing melanin production, cinnamic acid helps fade dark spots, acne scars, and uneven pigmentation over time.
Provides Antioxidant Protection
Exposure to UV rays and pollution generates free radicals, leading to premature ageing and skin issues. Cinnamic acid’s antioxidant properties neutralize these free radicals, preventing further skin darkening and supporting a more even skin tone.
Reduces Inflammation
Cinnamic acid has anti-inflammatory effects that calm irritated skin, indirectly helping to reduce the formation of post-inflammatory hyperpigmentation.
