Properties and effects of caffeic acid

Antioxidant effect

Caffeic acid neutralizes reactive oxygen species (ROS) and prevents oxidative damage to cells. It has the ability to block carcinogenic compounds formed during the metabolic conversion of certain carcinogens, such as nitrosamines and 4-nitroquinoline-1-oxide. Additionally, it protects LDL cholesterol from oxidation, thus inhibiting the process of atherogenesis. Caffeic acid also supports the recycling of α-tocopherol (vitamin E) to its active form and demonstrates greater antiradical activity than vitamin E.

Anti-inflammatory and antimicrobial effects

Caffeic acid is known for its anti-inflammatory properties, which help reduce inflammation in various skin conditions. Furthermore, it possesses antimicrobial properties that protect against numerous microbial threats. These properties make caffeic acid effective in treating dermatoses such as scabies and other inflammatory skin conditions. It protects the skin from the harmful effects of UV radiation by preventing the degradation of collagen and elastin fibers, which are crucial for maintaining skin elasticity and firmness.

Anti-aging benefits

One of the key benefits of caffeic acid is its ability to prevent wrinkle formation. By combating free radicals and inhibiting oxidative stress, it helps slow the skin’s aging process. Its protective effects also include protecting collagen and elastin fibers from degradation, helping to maintain the skin’s structural integrity and elasticity.

Depigmenting effect

Caffeic acid works by inhibiting the enzyme tyrosinase, responsible for melanin production, which helps prevent the formation of new age spots and sun spots. Therefore, it is an excellent ingredient in skincare products for skin with discoloration problems, including those caused by sun damage or aging.

Use of caffeic acid

Caffeic acid is typically used in skincare products at concentrations up to 2%. It is recommended for mature skin, protecting against sun damage, and preventing the signs of photoaging. After treatments with caffeic acid, skin becomes brighter, more moisturized, oxygenated, and radiant, with visibly reduced wrinkles and improved elasticity.
