Hydroxycinnamic Acid
What Hydroxycinnamic Acid is & what it does
Hydroxycinnamic Acid is a class of plant-derived phenolic acids, with caffeic, ferulic, and coumaric acids among the common members. In skincare and sunscreen formulas these compounds are valued as antioxidants that help protect the formula and skin from oxidative stress. Their phenolic structure, which can also absorb some UV light, is their notable feature.
What does Hydroxycinnamic Acid do in skincare?
Hydroxycinnamic acids, a group that includes ferulic and caffeic acid, are used mainly as antioxidants in skincare and sunscreen formulas. They help neutralize free radicals and can support the stability of the formula, and some members also absorb a portion of UV light. They are supportive ingredients rather than primary sunscreen filters.
Is Hydroxycinnamic Acid safe?
Hydroxycinnamic acids are plant-derived phenolic compounds used in cosmetics and are generally well tolerated at the levels used. They are best known in antioxidant blends such as those with ferulic acid. Individual responses vary, so patch testing a new product is a reasonable precaution.
Is Hydroxycinnamic Acid natural or synthetic?
Hydroxycinnamic acids occur naturally in many plants, fruits, and grains, but the versions used in cosmetics may be either plant-extracted or produced synthetically. Both routes yield the same type of compound. The source can depend on the specific supplier and grade.
