Grape Seed Polyphenols

Grape seed polyphenols in brief

Grape seed polyphenols is a liquid that dissolves in water. Grape seeds are one of the best-known sources of polyphenols, especially proanthocyanidins, which are valued for antioxidant activity. In skin care, these compounds suit products that aim at radiant, firmer-looking skin and help protect skin from the look of environmental stress. Each lot's CoA confirms the INCI and the level to use.

Seeds versus skins

Our catalog offers both grape seed and grape skin polyphenols. The seeds and the skins carry different polyphenol profiles, which gives a brand two related stories. Seeds are often linked with firmness and protection, while skins are linked with radiance and color. Using both in one line covers the whole grape.

Product formats

Firming-look serums

A serum with grape seed polyphenols, peptides and hyaluronic acid supports a firmer-looking, radiant skin story.

Eye care

Eye creams and gels aim at a fresher, smoother look around the eyes.

Body products

Body lotions and firming-look body creams extend the grape story beyond the face.

Processing

Add the liquid below 40 °C and stir until uniform. Use a chelating agent such as disodium EDTA or sodium phytate, because polyphenols can darken with metal ions. Avoid iron or copper tools.

Partners

Grape Skin Polyphenols builds a two-part grape line. Tocopherol and peptides add antioxidant and firming-look partners. Instant lifting Complex adds a quick tightening feel to an eye gel. More actives are available in the actives catalog.

Color and stability

Polyphenol extracts can be pink to brown and may darken over time, especially in light. Test color in light and dark storage and choose opaque packaging if needed.

Testing

Run stability tests in light and dark. Check pH and odor over time. A panel can rate radiance and smoothness after four weeks.

Claims

Use appearance wording: radiant, firmer-looking, smoother skin; helps protect skin from the look of environmental stress.

Vinotherapy and gift ideas

A grape seed serum and a grape skin toner make a natural pair for a vinotherapy line. Deep red packaging and vineyard imagery suit the theme. Holiday gift sets with a serum and a cream are easy sellers.

Formula protection

Polyphenols also help protect the oils in a formula from oxidation. Combining them with tocopherol covers both the water and oil phases.

Sourcing

Grape seeds are a by-product of wine and juice making, so grape seed ingredients can support an upcycling story. Ask the supplier for documentation about the source before using the claim. Keep it with the CoA, and update it if the supplier changes.

Packaging

Opaque or amber packaging protects polyphenol products from light and keeps their color stable for longer.

Storage

Store closed in a cool place away from light. Close the bottle after use.
