White tomatoes are real, but a pale tomato is not automatically a richer source of colourless carotenoids. Fruit colour alone cannot tell you how much phytoene or phytofluene a tomato contains—or whether a supplement made from it will improve skin pigmentation. Those questions require composition testing and evidence for the specific formulation.
If you are researching white tomato supplements, three things are worth separating: the colour of the fruit, the compounds in the ingredient, and the results demonstrated for the finished product.
What are colourless carotenoids?
Tomatoes contain several carotenoids. Lycopene contributes to their familiar red colour, while beta-carotene contributes orange colour. Phytoene and phytofluene are different: they are colourless carotenoids that occur within the same biosynthetic pathway.
Researchers can identify these compounds by their characteristic light-absorption patterns. Phytoene and phytofluene absorb in the ultraviolet region rather than producing the visible colours associated with lycopene and beta-carotene. They can also be present in red tomatoes; they are not exclusive to pale fruit. Research on tomato colour and carotenoid profiles helps explain this distinction.
A compound's ability to absorb ultraviolet light in a laboratory does not, by itself, establish the protection someone receives by consuming it. Composition, absorption and clinical outcomes are separate questions.
Do white tomatoes contain more colourless carotenoids?
Not necessarily. A 2024 study compared particular white- and yellow-fleshed tomato lines and found lower overall carotenoid accumulation in the white fruit. Small amounts of phytoene were detected in both groups. The researchers also investigated a genetic variation near a gene involved in carotenoid production. Read the white-flesh tomato study.
These findings apply to the plants studied. They do not establish a universal percentage difference for every white tomato variety, or prove that all pale tomatoes lack colourless carotenoids. They also do not measure the nutritional value of the whole fruit or its effect on human skin.
The useful question is therefore not simply whether a tomato looks white. It is which carotenoids were measured, in what amounts, and in which variety or processed ingredient.
Is tomato powder the same as eating fresh tomatoes?
No. Processing and concentration can change the amount of an ingredient supplied in a serving. But concentration is not the same as absorption.
In a study comparing tomato powders with fresh tomato pulps, the most concentrated powder supplied much higher levels of phytoene and phytofluene. However, the fraction released during simulated digestion was lower in the powders, and changed when oil was added. The researchers assessed potential availability using a laboratory digestion model, not a clinical skin-lightening outcome. Read the tomato-powder bioaccessibility study.
This distinction matters when comparing supplements. A claim about carotenoid concentration cannot automatically be restated as the same increase in absorption—or in visible skin results.
How to assess a white tomato supplement claim
Look beyond the ingredient's name and check:
- Identity: does the label specify tomato powder, an extract, or measured carotenoids?
- Amount: is the stated quantity per caplet, per daily serving, or per gram of raw material?
- Comparison: if a claim says “more”, what exactly was compared and measured?
- Evidence: was the finished product studied in people, or does the claim refer to an ingredient or laboratory test?
- Study conditions: who participated, how long did they use it, and what other skincare or treatments were used?
These questions help you assess a product more meaningfully than a photograph of a pale tomato or a headline about a single ingredient.
Where does Crystal Tomato® fit?
Crystal Tomato® Whitening Supplement combines non-GMO tomato powder containing colourless carotenoids with L-cysteine. Its formulation should be assessed by its ingredient information and product-specific research, rather than by assuming that “white tomato” describes either its composition or its effects.
The supplement has been evaluated in a placebo-controlled clinical study at the National Skin Centre, Singapore. You can read the Whitening Supplement study summary to explore what was measured and reported. Evidence for a particular formulation should not be assumed to apply to every product marketed as a white tomato supplement.
Frequently asked questions
Are white tomatoes a myth?
No. White-fleshed tomato varieties exist. The misconception is that their pale appearance alone proves they contain unusually high levels of colourless carotenoids.
Can red tomatoes contain colourless carotenoids?
Yes. A red tomato can contain phytoene and phytofluene alongside visible pigments. Its appearance does not reveal the amount of each compound.
Does higher carotenoid content mean better skin results?
Not by itself. The amount in an ingredient, the amount available for absorption and the outcome measured in a clinical study are different things. Look for evidence relevant to the finished product and the result being claimed.
Are all white tomato supplements equivalent?
No. Products can differ in their ingredients, quantities and supporting research. Compare their labels and study details rather than relying on the shared marketing term.
