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.
