Ginseng is a plant that has been used for many years in traditional Chinese medicine.
The specific variant, black ginseng, is processed through heating and drying, which alters its chemical composition.
According to the National Center for Complementary and Integrative Health, ginseng is used, among other things, to help the body manage stress.
In addition, the black variety contains more active compounds with antioxidant effects.

Laboratory studies
New research has tested black ginseng extract on skin cells in the laboratory.
A study published in the Journal of Dermatologic Science and Cosmetic Technology shows that the substance may inhibit an enzyme that breaks down collagen.
Collagen is important for the skin’s firmness, and when it is broken down, the skin becomes less elastic.
Other studies, including those from Applied Sciences and the Journal of Ginseng Research, also suggest that the extract may reduce inflammation and stress in the skin.

Still uncertain
Although the results appear promising, there are several reservations.
Some of the research has been conducted in collaboration with companies that develop products containing the substance.
In addition, most studies have been carried out on cells or animals, not humans. Therefore, there is still limited knowledge about how it works in practice and over the long term.
Black ginseng extract may potentially influence skin aging, but researchers and dermatologists assess that there is not yet sufficient evidence to recommend it widely.
