Properties and effects of coffee acid
Antioxidant activity Coffee acid neutralizes reactive oxygen species (ROS) and prevents oxidative damage to cells.
It has the ability to block carcinogenic compounds formed during metabolic conversion of some carcinogens, such as nitrosamines and 4-nitroquinoline-1-oxide.
In addition, it protects the LDL cholesterol fraction from oxidation, thereby inhibiting atherogenesis.
Coffee acid also promotes the recirculation of α-tocopherol (vitamin E) to its active form and exhibits greater antiradical activity than vitamin E. Anti-inflammatory and antimicrobial activity Coffee acid is known for its anti-inflammatory activity, which helps reduce inflammation in various skin conditions.
In addition, it has antimicrobial properties that protect against many microbial threats.
These properties make coffee acid effective in treating dermatoses, such as scabies, and other skin conditions where inflammation is present.
It protects the skin from the damaging effects of UV radiation, preventing the degradation of collagen and elastin fibers, which are key to maintaining skin elasticity and firmness. Anti-aging benefits One of the key benefits of coffee acid is its ability to prevent wrinkles.
By fighting free radicals and inhibiting oxidative stress, it helps slow down the skin’s aging process.
The protective effects of coffee acid also include protecting collagen and elastin fibers from degradation, which helps maintain the structural integrity and elasticity of the skin. Depigmentation action Coffee 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 skin care products for skin with hyperpigmentation problems, including those caused by sun damage or aging.
Use of coffee acid
Coffee acid is typically used in skin care products in concentrations of up to 2%.
It is recommended for mature skin care, protection against sun damage and in preventing signs of photoaging.
After treatments with coffee acid, the skin becomes brighter, more hydrated, oxygenated and radiant, with wrinkles visibly diminished and elasticity improved.
