Scurvy produces a distinctive set of visible changes, most notably on the skin, gums, and hair. The earliest signs are tiny pinpoint bleeds around hair follicles on the legs, followed by coiled “corkscrew” hairs and swollen, purplish gums. These symptoms develop after roughly 8 to 12 weeks of consuming little to no vitamin C, which the body needs to produce collagen, the structural protein that holds skin, blood vessels, and connective tissue together.
Skin Changes: Bleeding and Bruising
The most recognizable skin sign of scurvy is perifollicular hemorrhage: tiny red or purple dots that appear around individual hair follicles, especially on the shins, thighs, and buttocks. These pinpoint bleeds happen because the small blood vessels surrounding each follicle become fragile without adequate collagen. At first glance, they can look like a rash or even broken capillaries from minor bumps.
As the deficiency progresses, those small dots merge into larger patches of bruising. The skin may show purple or brownish discoloration that spreads well beyond the original follicular spots. In some cases, the bruising extends deep into muscle tissue. One case study documented a large blood collection within the calf muscle of a patient whose skin findings initially looked like an inflammatory blood vessel condition. The key visual difference is location: scurvy bruising clusters around hair follicles in a scattered, follicle-centered pattern, while other causes of purpura tend to produce raised, “palpable” patches that aren’t tied to individual follicles.
Bleeding can also appear under the fingernails and toenails as dark, splinter-like lines running lengthwise beneath the nail plate.
Corkscrew Hairs and Rough Skin
One of the most specific visual clues is a change in hair shape. Body hairs, particularly on the legs, coil into tight spirals sometimes called “corkscrew hairs.” This happens because the growing hair shaft becomes structurally weakened and bends back on itself inside the follicle. The surrounding skin also thickens and roughens around each follicle, creating small, raised bumps that feel like sandpaper. Together, these coiled hairs sitting inside rough, plugged follicles are considered a hallmark finding, meaning they point almost exclusively to vitamin C deficiency rather than other conditions.
Existing body hair may also become brittle and break off close to the skin surface, leaving stubbled patches alongside the coiled hairs.
Gum and Dental Changes
The gums are often the most dramatic-looking area. In scurvy, gum tissue becomes swollen, spongy, and deep purple or reddish-blue. The gums bleed easily, sometimes spontaneously, and may visibly bulge between the teeth. This swelling is caused by weakened blood vessels and breakdown of the connective tissue that anchors gum tissue to bone.
Over time, the gums can recede and teeth loosen. In severe cases, teeth fall out entirely. People who already have gum disease before developing scurvy tend to experience worse damage. Even after vitamin C levels are restored, dental and gum problems may take weeks to months to fully resolve, and severe gum disease can cause permanent damage to the supporting bone structure.
Joint Swelling and Leg Pain
About 80% of people with scurvy develop musculoskeletal symptoms. Joints, particularly the knees and ankles, may swell from internal bleeding into the joint space. The legs can become visibly puffy and tender, and walking may become painful enough that a person avoids putting weight on their legs. Deep muscle bleeding can also produce firm, swollen areas in the calves or thighs that look like a blood clot or deep bruise.
Old scars and previously healed wounds sometimes reopen or become red and raised again. This happens because the collagen that formed during the original healing process breaks down without ongoing vitamin C to maintain it.
How Scurvy Looks in Children
Children with scurvy often present differently than adults. Rather than the classic skin and gum findings, the most visible sign in infants and young children is leg pain and refusal to move. A child may hold their legs in a “frog-leg” position, crying when their limbs are touched. Visible swelling along the shins or thighs can occur from bleeding beneath the membrane that covers the bone. In severely disabled children who may already have limited diets, scurvy can cause fractures from minor bumps, delayed bone healing, and overgrowth of gum tissue. Bruising that seems out of proportion to any known injury is a common early sign.
What Scurvy Can Be Mistaken For
Because the skin findings involve widespread bruising and a rash-like appearance, scurvy is frequently mistaken for other conditions. It has been confused with blood vessel inflammation (vasculitis), low platelet counts, blood cancers, and even physical abuse in children. The distinguishing features are the follicle-centered pattern of the bleeding, the presence of corkscrew hairs, and the rough, thickened skin around follicles. A skin sample from a scurvy patient will show coiled hairs and bleeding concentrated around follicles rather than the vessel-wall inflammation seen in vasculitis.
Scurvy is diagnosed when blood levels of vitamin C fall below 0.2 mg/dL. Levels between 0.2 and 0.6 mg/dL are considered borderline and may produce subtler versions of the same signs.
How Quickly It Develops and Resolves
Visible symptoms typically appear after two to three months of getting almost no vitamin C. The earliest changes are subtle: fatigue, irritability, and small follicular bleeds that are easy to overlook. Gum changes and corkscrew hairs follow as stores drop further. Left completely untreated, scurvy is fatal.
The good news is that recovery is fast once vitamin C is restored. Even people with severe symptoms, including large bruises, swollen joints, and spongy gums, typically return to normal health within weeks of supplementation. Skin bleeding and fatigue tend to improve within days, while gum and dental recovery takes longer. Permanent damage is rare if the condition is caught before teeth are lost or significant bone changes occur.
