Blueberry Extract
INCI: Vaccinium Myrtillus Fruit Extract (or) Vaccinium Angustifolium Fruit Extract
A purple-blue antioxidant extract from blueberries or bilberries. High in anthocyanins, vitamin C, and small amounts of natural acids.
Overview
Blueberry extract for cosmetics comes from two related species: highbush blueberry (Vaccinium angustifolium or corymbosum) and bilberry (Vaccinium myrtillus). The bilberry is the wild European cousin with substantially higher anthocyanin content per gram. Cosmetic suppliers sometimes use the names interchangeably; check the INCI to know what you actually have.
The extracts come as deep blue-purple liquids in water/glycerin or as freeze-dried powders. Both deliver the same antioxidant compounds: anthocyanins (which give the colour), flavonoids, vitamin C, and small amounts of fruit acids that contribute mild exfoliation at higher rates.
Shelf life is 12-18 months for the liquid form. Light degrades the anthocyanins, so store in dark or opaque containers.
What it does in a formula
The defining benefit is antioxidant protection. Blueberry/bilberry anthocyanins are measurably effective at quenching free radicals in the upper skin layers. Specifically:
- Antioxidant scavenging — high ORAC value (antioxidant capacity) means real free-radical defence at topical application rates
- Mild skin brightening — the small fraction of vitamin C contributes to even skin tone over weeks of use
- Capillary support — anthocyanins have evidence for strengthening small blood vessels, which is why bilberry has a long traditional use for “broken capillaries” and rosacea-style redness
- Mild anti-inflammatory effect
The capillary support is the property that distinguishes blueberry from the broader antioxidant pack. If you formulate for couperose or rosacea-prone skin, blueberry is a sensible choice.
How to use
Add to the cool-down phase, below 40 C. Anthocyanins fade above 60 C.
Usage rates by product type:
- Antioxidant serums: 3-5%
- Anti-redness creams: 2-4%
- Eye creams (for dark circles, mild capillary support): 2-4%
- Face lotions: 1-3%
- Sheet mask essences: 2-5%
- Hand creams: 1-3%
It pairs well with niacinamide (anti-redness amplifier), with vitamin C derivatives (antioxidant synergy), and with horse chestnut extract (which also supports capillary strength).
Best for / Worst for
Best for: rosacea-prone skin, anti-redness face creams, eye creams targeting dark circles caused by vascular issues, antioxidant serums, broken-capillary support products, mature skin formulas.
Worst for: white or pale-coloured products (the purple tint shows), very oily acne-prone skin (no specific benefit), strict mineral-ingredient formulations.
Common pitfalls
Buying watery extracts. Many “blueberry extracts” on the cheap end are mostly water with a touch of dye. Look for extracts with measurable anthocyanin content (often given as cyanidin-3-glucoside or “total anthocyanins” mg/g).
Light degradation. Anthocyanins fade in light. Use opaque packaging and dark storage during formulation.
Confusing bilberry with blueberry. Both work, but bilberry typically has 3-5x the anthocyanin density. If you want capillary-strengthening effects, choose bilberry specifically.
Substitutes
- Bilberry extract — concentrated cousin (often the better choice if you can find it).
- Acai extract — different polyphenol profile, similar antioxidant strength.
- Black currant extract — very similar role and pigment.
- Pomegranate extract — different polyphenol class, similar antioxidant role.
- Horse chestnut extract + niacinamide — closer match for the capillary-support claim if you cannot get bilberry.
