Wrinkles, loose skin and splits tell different stories. Learn to read the surface of a date without expecting every fruit to look the same.
A date’s skin can tell you something about its variety, moisture and handling. It can also change how the fruit feels when eaten. Wrinkles, loose areas, splits and pale deposits deserve different interpretations; treating them all as imperfections makes it harder to judge the fruit fairly.
Begin with the cultivar and the stage at which it is sold. A smooth fresh date and a deeply wrinkled mature date may both be in good condition. The surface is evidence to consider, not a complete account of what is inside.
The skin has a job to do
The outer layers help protect the developing fruit. As the date grows, softens and loses water, its skin and flesh do not always change in exactly the same way. The surface you see at maturity reflects that development as well as what happened after harvest.
It is also part of the eating experience. A fine skin may give way almost immediately; another can remain distinct as the flesh softens in the mouth. This is why two dates with equally tender centres may feel different when eaten whole.
For practical purposes, it helps to distinguish the surface’s normal character from damage that breaks its continuity. Folded skin, separated skin and an open split are different things.
Wrinkles are often normal
Many familiar mature dates have wrinkles. Moisture loss and changes in the flesh can leave folds in the outer surface. Their depth, direction and prominence vary between cultivars and between individual fruit.
A Medjool commonly has more pronounced folds than a slender Deglet Nour. Comparing one against the other as though smoothness were a universal standard would confuse variety with condition.
Look instead at whether the fruit has the general appearance expected for its type. A date that is unusually shrivelled for the product, with very hard flesh, may have lost a texture you would enjoy. That is a different judgement from rejecting every visible wrinkle.
Loose skin is not the same as a split
Skin separation happens when the outer skin lifts away from the flesh, sometimes forming a loose or puffy area. The skin can remain intact, so there need not be an opening into the fruit.
The extent matters to the eating experience. A small area may scarcely be noticed, while extensive papery skin can become the dominant sensation. Buyers and graders may reasonably prefer closer-fitting skin for a particular presentation, without treating every separated patch as evidence of decay.
Research published in 2024 found both genetic and environmental contributions to skin separation. The tendency varies among cultivars, and environmental conditions alone do not explain all of the differences. That makes it too simple to label every example a storage failure.

A split is different: it is a break in the surface. Its extent, the exposed flesh and the product’s condition all matter. If you are buying dates to serve whole, choosing sound fruit with an intact surface is a useful starting point.
Colour variation needs context
Skin colour ranges widely among dates, from yellow or red at certain stages to amber, brown and almost black. A dark patch cannot be interpreted fairly without knowing the cultivar and maturity.
Partly ripened fruit may show more than one colour. Lighting can exaggerate those differences, especially in close photography. A strongly lit ridge may look pale while the fold beside it looks almost black.
Examine the fruit in ordinary light and consider the whole surface. Colour alone cannot establish whether a date is fresh, authentic or safe. If an area also shows obvious damage, unusual wet deterioration or mould, the concern comes from that wider evidence.
White marks may be sugar
Dates can develop pale sugar crystals on the surface or within the flesh. They may appear granular and can make the bite feel less smooth. Crystallisation is a recognised quality change during storage. UC Davis on sugar spotting
That does not mean every white mark is harmless. Mould can also appear pale, and a written description is not a dependable diagnostic test for a particular pack. Do not scrape an uncertain patch away and assume the remaining fruit is safe.
If you cannot confidently identify a change, avoid eating the suspect fruit and ask the seller about the product. Visible mould or other clear signs of spoilage are reasons to discard it, rather than to taste it for reassurance.
A glossy surface is not a quality grade
Some dates have a natural sheen; others look relatively matt. Moisture, surface condition and lighting all influence the impression. Commercial products may also have declared treatments or added ingredients.
Read the ingredient list if that distinction matters to you. A photograph cannot reliably tell you whether a shine comes from the fruit, the lighting or a treatment. Equally, a matt surface does not establish that one product is more natural or better than another.
The meaningful question is whether the product is accurately described and enjoyable in its intended form. A surface made dazzling for a photograph may reveal less than a plainly lit view of the same date.
The skin cannot tell the whole story
A sound exterior is useful, but it cannot reveal every internal defect. When preparing dates, open the fruit as needed, remove the stone and notice anything unexpected in the flesh. Do not use tasting to investigate signs of spoilage.
For an otherwise sound date, tasting brings the surface and centre together. Does the skin break cleanly? Does it remain papery after the flesh has softened? Is that sensation pleasant to you? These questions help distinguish your preference from a cosmetic judgement.

Use a clean cut and plain background; place the anatomical terms in selectable text. Do not use generated diagnostic or microscopic imagery.
Keep the same distinction when buying. Natural folds and modest variation belong to fruit. Extensive damage, contamination and uncertain changes deserve a different response. Learning to read the surface means knowing which observations are useful, and where the evidence stops.
