The fact that the skin is the most visible organ makes us aware of the aging process every minute. Chronological and photo-aging can be easily distinguished clinically, but they share important molecular features. A team of international scientists have tried to gather the most interesting evidence based on facts about plants and plant extracts used in antiaging products. Some of these have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin. Some plants can affect skin elasticity and tightness.
Clinical manifestation of chronologically aged skin includes xerosis, laxity, wrinkles, slackness, and the appearance of a variety of benign neoplasms such as seborrheic keratosis and cherry angioma. Hair becomes depigmented, terminal hair converted to vellus hair, loss of hair is increased. There are changes in nail plate. There are fewer glands in aged skin. The most evident and reproducible biological feature of ageing skin is the flattening of the dermal-epidermal junction, reflected by decreasing number of fibroblasts, reduced levels of collagen and elastin, and their organization is impaired.
There is now increasing scientific interest in reducing the appearance of aging . Plants produce a great variety of organic compounds and can be classified into three major groups: terpenoids, alkaloids, and phenolic compounds. Scientists have underlined the specific benefits of following herbal extracts.
Flavonoids: Like Rutin and phenolic compounds, have anti-tumor, antiviral and antibacterial activities, and antiradical and antioxidative activities. The extract of the fruits of the coffee plant has shown to exhibit antioxidant activity mediated by potent antioxidant polyphenols. This extract showed improving fine lines, wrinkles, pigmentation, and overall appearance. Apigenin, a nontoxic botanical-derived fiavonoid occurring in numerous herbs, fruits, and vegetables.
Curcumin obtained from the turmeric rhizome (Curcuma longa), Proanthocyanidins from the seeds of grapes, and Resveratrol, a polyphenol found in numerous plant species including grapes, peanuts, fruits, red wine, and mulberries, have also shown to possess the ability to protect the skin from harmful UV-induced effects by displaying antimutagen, antioxidant, free radical scavenging, anti-inflammatory, and anticarcinogenic properties.
Extract of Mulberry (Morus alba) exhibited super oxide scavenging activity that is involved in the protection against autooxidation.
Basil, Oregano and Thyme essential oils: Their antioxidant activity has been evaluated in a series of in vitro tests. The antioxidant activity of Thymus species may be due to different mechanisms, such as prevention of chain initiation, decomposition of peroxides, prevention of continued hydrogen abstraction, free-radical scavenging, reducing capacity, and binding of transition metal ion catalysts.
Green tea: Both oral consumption and topical application of green tea protects against inflammation and chemical- and UV-induced carcinogenesis. In addition, UV-induced immunosuppression is prevented by Green tea
Seeds of Milk thistle: It possess anti-inflammatory, antioxidative, and anticarcinogenic properties. Moreover, Silymarin may favorably supplement sunscreen protection and provide additional antiphotocarcinogenic protection.
Pomegranate extract: Excellent supplement in skin care products. The Catechin, an active component of Punica granatum, inhibited the UVB-induced skin photoageing.\
Soybean cake: Isoflavone extract from soybean is a good candidate for an anti-photo-ageing agent in skin care. Furthermore, Isoflavone extract prevents skin cell apoptosis, erythema, and inflammation reactions.
Herbally Radiant is well engaged to analyze and investigate the revitalizing properties of plants and flowers, and is combining them to create superb formulations for anti-aging regime as well as for fighting skin disorders like acne, spots, blemishes and allergies.
