INCI: Rubus Fruticosus (Blackberry) Fruit Extract - Also known as: Common Blackberry Extract, Bramble Extract

QUICK FACTS

What is Blackberry Extract (Rubus Fruticosus)?

Blackberry (Rubus fruticosus) fruit extract is derived from the common blackberry, a member of the Rosaceae family closely related to raspberry. Its deep purple-black color is produced by a high anthocyanin content - particularly cyanidin-3-glucoside and cyanidin-3-rutinoside, the same cyanidin-based anthocyanins that dominate elderberry's profile, giving blackberry and elderberry a complementary but distinct anthocyanin character within the Sweet Chemistry antioxidant botanical complex.

Beyond anthocyanins, blackberry fruit extract is notable for its ellagic acid and ellagitannin content - the same family of polyphenols found in pomegranate and raspberry that is studied in connection with antioxidant activity and the appearance of a more even skin tone. The combination of anthocyanins and ellagitannins in a single botanical gives blackberry extract a dual-class polyphenol profile that positions it among the more compositionally diverse of the berry extracts in the Sweet Chemistry formula.

Blackberry also contains vitamin C, quercetin, kaempferol, and gallic acid - flavonols and hydroxycinnamic acids that round out its polyphenol spectrum and contribute to its standing as a multi-class botanical antioxidant source. At Sweet Chemistry, organic Rubus fruticosus fruit extract is present above 1% in all three water-based formulas as part of the eight-botanical organic antioxidant superfood complex.

What does it do for skin?

Blackberry extract's studied contributions center on its anthocyanin and ellagitannin antioxidant content. Its cyanidin-based anthocyanins contribute water-phase free radical scavenging character studied in connection with protecting the skin's surface from UV-associated and environmental oxidative stress - an association consistent with the broad antioxidant approach of the botanical complex it is part of.

The ellagic acid and ellagitannin fraction gives blackberry extract a brightening-associated research footprint. Ellagic acid has been researched in connection with the appearance of hyperpigmentation and a more even-looking complexion - an association that complements the tone-related research profiles of niacinamide, THD ascorbate, bisabolol, amla, and apple in the same formulas. These are research-based associations rather than clinical claims, and individual results will vary.

Quercetin and kaempferol - flavonols found in blackberry alongside the anthocyanins - are studied in connection with a more settled skin surface and have been researched in relation to surface comfort-associated pathways. In the context of Sweet Chemistry's multi-ingredient soothing system (bisabolol, panthenol, allantoin, colloidal oatmeal), the flavonol content of blackberry extract adds a botanical polyphenol dimension to the formula's approach to skin surface comfort.

Within the eight-botanical antioxidant complex, blackberry's cyanidin anthocyanin profile is complementary to blueberry's multi-anthocyanin diversity, elderberry's cyanidin sambubioside character, and cranberry's proanthocyanidin depth - together creating an anthocyanin and polyphenol environment that is broader in spectrum than any individual botanical extract could provide.

WORKS TOGETHER WITH

Botanical Extract Elderberry (Sambucus Nigra) Fruit Extract

INCI: Sambucus Nigra (Elderberry) Fruit Extract.

Organic above 1% in all three water-based formulas alongside blackberry. Synergy Note: Blackberry and elderberry both feature cyanidin-based anthocyanins as their primary anthocyanin class - their combined presence creates a reinforced cyanidin antioxidant contribution, while their different glycoside patterns (glucoside in blackberry, sambubioside in elderberry) mean they represent slightly different molecular structures within the same anthocyanin family.

Botanical Extract Cranberry (Vaccinium Macrocarpon) Fruit Extract

INCI: Vaccinium Macrocarpon (Cranberry) Fruit Extract.

Above 1% in all three water-based formulas alongside blackberry. Synergy Note: Blackberry's ellagic acid and ellagitannin content complements cranberry's proanthocyanidin character - both polyphenol classes belong to the condensed and hydrolysable tannin families but operate through different antioxidant and studied skin association mechanisms.

Polyphenol Antioxidant Resveratrol

INCI: Resveratrol.

Present in all three water-based formulas as part of the enzymatic antioxidant trio. Synergy Note: Blackberry's anthocyanin and flavonol antioxidants operate through flavonoid pathways; resveratrol's stilbene structure addresses a complementary polyphenol mechanism. Their co-presence creates a broader multi-class polyphenol antioxidant approach than either independently provides.

ECM Peptide Complex Matrikynes® Bone Peptides

INCI: Hydrolyzed Cow Bone Extract.

At 3% in all four formulas. Synergy Note: Blackberry's polyphenol antioxidant system contributes to the low-oxidative environment associated with favorable conditions for Matrikynes® peptide activity - botanical antioxidant protection and structural peptide renewal working in complement.
