Strawberry Extract
INCI: Fragaria Ananassa (Strawberry) Fruit Extract
A pink-red extract from the strawberry fruit. High in vitamin C, ellagic acid, and natural fruit acids. Mild brightening and antioxidant action.
Overview
Strawberry extract is made from the fruit and seeds of cultivated strawberries (Fragaria ananassa). It comes as a pink-red liquid in water/glycerin, or as a freeze-dried powder. The colour is from anthocyanins; the active ingredients of interest are vitamin C (strawberries are unusually high in it), ellagic acid (a polyphenol with documented skin-brightening evidence), and small amounts of natural salicylic-style acids.
Among the common fruit extracts, strawberry stands out for two specific properties:
- High vitamin C content — strawberries deliver more vitamin C per gram than oranges, and a meaningful fraction survives into the extract
- Ellagic acid — a polyphenol with measured tyrosinase inhibition (the enzyme that makes melanin), making strawberry extract one of the more credible “brightening” fruit extracts
Shelf life is 12-18 months for the liquid form.
What it does in a formula
- Mild brightening — the combination of vitamin C and ellagic acid acts on the melanin-formation pathway at the upper skin layers. Effects are gradual but real over 6-8 weeks of consistent use.
- Antioxidant protection — quenches free radicals in the upper skin layers
- Mild fruit-acid exfoliation — small amounts of natural salicylic-style and AHA-type acids
- Mild astringent feel — useful in toners for combination skin
It is one of the few fruit extracts with measurable tyrosinase-inhibition data. That makes it worth considering as a supporting active in brightening formulas, even though the percentage of ellagic acid in the extract is small.
How to use
Add to the cool-down phase, below 40 C. Anthocyanins and vitamin C fade with heat.
Usage rates by product type:
- Brightening serums: 3-5%
- Anti-pigmentation creams: 2-4%
- Toners: 1-3%
- Sheet mask essences: 2-5%
- Eye creams: 1-3%
- Body lotions: 1-2%
It pairs well with stronger brightening actives — alpha arbutin, niacinamide, ascorbyl glucoside — to add a supporting fruit-acid dimension to the formula.
Best for / Worst for
Best for: brightening serums, anti-pigmentation creams, “natural fruit”-positioned product lines, sensitive-skin alternatives to stronger acids, mature skin support, anti-sun-damage formulations.
Worst for: white or pale-coloured products (the pink tint shows), strongest pigmentation cases (use prescription tranexamic acid or 4-butylresorcinol for those), strawberry allergy (rare but real — flag on the label).
Common pitfalls
Strawberry allergy. A small percentage of people have IgE-mediated strawberry allergy. The cosmetic risk is low (allergy is usually triggered by ingestion or oral contact), but topically it can cause hives in sensitive individuals. Label clearly.
Confusing extract with seed oil. Strawberry seed oil is a different product, an omega-3-rich carrier oil. The extract is the water-soluble brightening ingredient.
Heat sensitivity. Add to cool-down phase only.
Substitutes
- Raspberry extract — closely related, similar vitamin C content.
- Cranberry extract — similar role, different colour.
- Pomegranate extract — different polyphenol, similar brightening claim.
- A direct combination of ascorbyl glucoside + niacinamide — for measurable brightening without the fruit dimension.
- Apple extract — milder option in same category.
