If you’ve stumbled upon ursolic acid in your beauty products and are curious about what it does, you’ve come to the right place. Here we take a closer look at the science behind the skincare benefits of ursolic acid and explain everything in simple terms.
What is ursolic acid?
Ursolic acid is a naturally-derived compound found in fruits and plants (like apples, rosemary, oregano, and berries) that protects against pathogenic microbes. In the context of skin, ursolic acid packs quite a few benefits thanks to its antioxidant, anti-inflammatory, and antibacterial properties.[1]
Ursolic acid benefits for skin
First of all, ursolic acid fights harmful free radicals. These unstable molecules come from external sources such as pollution, smoke, and UV exposure and can affect every cell and tissue in your skin. So how does it work? Well, ursolic acid is shown to stimulate the activity of antioxidants. Think of superoxide dismutase, glutathione, and vitamins C and E, which are like the body’s natural defense system against free radicals.[2]
By interfering with free radicals, ursolic acid not only has the potential to mitigate UV damage and photoaging but also to reduce the degradation of epidermal lipids.[3] These lipids have the role of maintaining the function of the skin’s barrier. By protecting them, ursolic acid can provide additional benefits in supporting skin recovery.[4]
Moreover, ursolic acid work as an anti-wrinkle and wound-healing treatment as it can preserve collagen levels. More collagen is necessary to accelerate tissue repair and maintain the elasticity and firmness of the skin. In fact, studies have shown ursolic acid can restore skin integrity and block specific enzymes from attacking structural proteins.[5]
The bottom line
As far as the list of benefits goes, the research into ursolic acid is far from conclusive. That being said, ursolic acid remains, at best, a questionable ingredient in the skincare scene. It might not be the most researched one, but it’s definitely good to have it in your products.

![Does resveratrol in red wine benefit your skin? While sipping on a glass of red wine can be a delightful experience, relying on it for skincare benefits is not the best idea. Sure, red wine contains a smidge of resveratrol, but let's put things into perspective. The concentration of resveratrol in red wine is relatively low. Red wines, specifically Pinot noir from France, typically contain 0.361-1.972 mg of resveratrol per liter.[8] To hit that reference dose of 500mg of resveratrol, you'd need to drink a lot of wine. We're talking about downing anywhere from 100 to 1000 glasses per day. It's a scene straight out of a wine lover's wildest dreams, but definitely not the healthiest approach.
