What is grape seed?
Grape seeds are the seeds of grapes, which is It is obtained after separating grape skin and grape stem after drying in the sun. Grape seeds are rich in amino acids, vitamins and minerals, and are a new type of highly effective natural antioxidant that cannot be synthesized by human body. Its antioxidant activity is 50 times that of vitamin E and 20 times that of vitamin C. It can effectively remove excess free radicals in the body.
The secret of grape seeds?
The ability of grape seed extract is mainly from proanthocyanidins (PC).
Proanthocyanidins are the general name of a large class of polyphenol compounds widely existing in plants, which can be divided into high polymer proanthocyanidins (PPC) and low polymer proanthocyanidins (OPC) according to their molecular weight.
The real effective is oligomeric proanthocyanidin （OPC）, which is also the key factor to measure the quality of grape seeds.
OPC components showed obvious dose-dependence on tyrosinase inhibitory activity, and increased with the increase of concentration.
The results showed：In a certain concentration range, grape seed extract has a down-regulation effect on tyrosinase protein expression in melanoma cells， and presents a relationship “dose-effect”.
What is the use of grape seeds?
Effectively prevent and reduce the skin damage caused by ultraviolet radiation, and inhibit the lipid peroxidation caused by free radicals.
Lighten the skin
The study showed that the pigmentation and melanin index of the people with spots were significantly reduced after taking OPC≥162mg daily for six months, and the further aggravation of spots in summer could be prevented. Long-term use can make skin smooth and elastic.
Protect the brain and eyes
Research shows that grape seed essence can easily cross the heart brain barrier, and is highly concentrated in the brain and nervous tissue. It is an ideal antioxidant for the brain. Protect eyes from radiation damage, and organize free radicals to oxidize lens protein.
Protect the pipeline
Maintain moderate permeability of capillaries, increase vascular strength and reduce capillary fragility.
Penetrate into cells, fundamentally inhibit the release of the allergen “histamine”, and improve the tolerance of cells to allergens; Effectively regulate the immunity of the body and improve the allergic constitution.
