There is a close association between grape skin extract and resveratrol, which is the key active ingredient in grape skin extract. The following is the specific analysis:
Source relationship: resveratrol is mainly found in the skin of grapes. When grapes are exposed to environmental stresses such as UV irradiation and disease attack, the skin will synthesize resveratrol in large quantities to defend against the threats. Therefore, grape skin extract is an important source of resveratrol, the content of which can reach 50-100mg/kg in grape skins.
Relationship between ingredient composition: Grape skin extract contains a variety of active ingredients, such as resveratrol, polyphenols (flavonoids and anthocyanins), fiber, and vitamins and minerals. Among them, resveratrol, as a polyphenolic compound, is an important component of the extract that exerts antioxidant, anti-inflammatory and anti-cancer effects.
Functional similarity: Resveratrol has antioxidant, anti-inflammatory and cardiovascular protective effects, which are highly consistent with the overall efficacy of grape skin extract. For example, resveratrol can prevent cardiovascular diseases by reducing blood viscosity, restoring blood vessel elasticity, inhibiting platelet clumping and dilating blood vessels, while grape skin extract is also believed to have these health benefits.
Application differences: Although resveratrol is an important ingredient in grape extracts, the applications of grape extracts are not limited to resveratrol. Other components in grape extracts may also have unique pharmacological effects and applications. For example, proanthocyanidins, which are rich in grape seed extract, have powerful antioxidant capacity and are widely used in skin care and health care products.
