A recent study published in Cosmetics, written by Nisakorn Saewan out of Thailand, sought to define the mechanisms by which coffee berry extract may work as a skin anti-aging and anti-hair loss active ingredient.
While Saewan notes that previous research has explored the impacts of coffee extract and there are cosmetics on the market containing the ingredient, research is light on the specific effects of the extract’s two main compounds, caffeine and chlorogenic acid.
“Our findings confirmed that coffee berry extract has high potential to be used as an active ingredient for skin anti-aging, anti-hair loss and hair growth stimulation in not only skincare but also hair care product applications,” Saewan said.
Here are the study’s findings in those three key areas.
Skin anti-aging effects
Saewan said previous studies have shown that coffee berry extract and chlorogenic acid specifically have shown promise in improving human dermal fibroblast cells, which are involved in wound healing and rejuvenating skin in anti-aging.
The study found that chlorogenic acid showed higher antioxidant activity than caffeine, which Saewan connects to studies showing that phenolic compounds like chlorogenic acid are “good free radical scavengers.”
Antioxidant activity is often important in anti-aging formulation in order to fight oxidative stress and photo-induced skin aging symptoms.
Saewan also evaluated the collagenase inhibition of coffee berry extract, which they said has been associated with preventing loss of elasticity in aging skin. Both caffeine and chlorogenic acid showed good metrics in collagenase inhibition, but the coffee berry extract before 10% to 20% respectively.
