A growing body of research shows that Ginsenosides and their metabolites can fight against ultraviolet radiation induced skin damage, which has big implications for combating age related skin deterioration.
Ginseng and Skin Health Research
Study 1: Red ginseng root extract mixed with Torilus fructus and Corni fructus improves facial wrinkles and increases type I procollagen synthesis in human skin: a randomized, double-blind, placebo-controlled study Seoul National University’s department of dermatology recently carried out a 24-week study in which 82 older women (average age 52 years) were given 3 grams of a Panax ginseng extract daily.
Over the course of observation facial wrinkles, epidermal water content, skin elasticity, erythema, and skin pigmentation were objectively measured by the research team. After analyzing the participant’s facial skin samples post treatment, the researchers found that their facial wrinkles improved significantly. In addition, their type I procollagen gene and protein expression were also increased.
Although there were significant improvements on a number of metrics, the study failed to demonstrate any significant differences in measured water content of the skin, skin pigmentation, and the skin's thickness and elasticity.
Study 2: Effects of red ginseng extract on UVB irradiation-induced skin aging in hairless mice The aim of this particular study was to assess the effects of Korean Red ginseng extract on UVB irradiation caused skin aging among hairless mice. The researchers determined the effects of ginseng supplementation by measuring skin wrinkles, immunohistology, and the expression of type I procollagen and MMP-1. Analysis showed that a dietary supplement containing 2.5% Korean Red ginseng extract had a significantly inhibitory effect on wrinkle formation as a result of chronic UVB radiation exposure.
Study 3: Photoprotective effect of red ginseng against ultraviolet radiation-induced chronic skin damage in the hairless mouse
Another study, carried out by a South Korean research team, was designed to see if Panax ginseng could treat the effects of UV-irradiation in the skin of hairless mice, such as deep wrinkles, cell infiltrations, increased skin thickness, and enlarged keratinizing cysts.
Study 4: Compound K induces expression of hyaluronan synthase 2 gene in transformed human keratinocytes and increases hyaluronan in hairless mouse skin One of the most common metabolites derived from Ginsenosides is Compound K, which has been implicated in improving skin health. Amore-Pacific Corporation’s R&D department carried out a study to test these purported health claims.
Sun care Sunlight contains ultraviolet (UV) rays, which are the main cause of skin ageing and can cause skin cancer. Sunburn can significantly increase the risk of skin cancer, so it's important to protect skin against sun damage at any age, but take special care with babies, children and young people.
To help protect yourself:
spend time in the shade between 11am and 3pm
cover up with clothes, a hat and sunglasses
use sunscreen with a sun protection factor (SPF) of at least 15
You need to spend some time in sunlight so your body can make vitamin D, which is essential for healthy bones.
Smoking Smoking is linked to early ageing of the skin. It's thought smoking reduces the skin's natural elasticity by causing the breakdown of collagen and reducing collagen production. Collagen is a protein that supports skin strength. It also reduces blood flow to your skin, so your skin gets fewer nutrients and less oxygen.
Alcohol When you drink alcohol, your body and skin can become dehydrated, leaving the skin looking older and tired. Drinking water can help your skin stay hydrated, preventing it drying out. When you have alcohol, try to drink within the recommended limits, and have a non-alcoholic drink, such as soda water or fruit juice, between alcoholic drinks.
Washing your skin Try to use mild soaps or bath oils – too much washing or using harsh soaps can wash away the natural oils that keep our skin healthy. If you have dry skin, don't use harsh alcohol-based products as these can irritate skin and dry it out. Moisturising can help prevent dry skin. If you have oily skin, avoid oil-based products and choose water-based ones instead.
