Snail extracts have been proven to have positive effects on acne scarring, acne prevention, dryness and hyperpigmentation. Daily application of topical products containing snail secretion is also shown to significantly reduce fine lines and wrinkles, according to a 2013 study published in the Journal of Drugs and Dermatology.
Researchers gathered 25 participants experiencing moderate to severe facial photodamage. One side of the subjects’ faces were treated with snail secretion, while the other side was treated with a placebo for a 12-week period.
“A significant reduction was noted in fine lines, deep wrinkles, as well as elasticity,” the study concluded. “Dryness and roughness resolved in all patients by day 90 as well.”
