Why Does My Horse Have Scabs on Its Face and Legs After Sunny Weather?

Overview
If your horse has scabs on its face and legs after sunny weather, photosensitivity is one possible reason. It often shows up on lighter or less protected skin, but other skin irritations can look similar, so it’s worth checking the pattern and your horse’s general condition rather than assuming it’s only the sun.
Things To Check
1. Check whether the scabs appeared after time in strong sunlight, especially on white or pink skin.
2. Look at where the scabs are. Face, muzzle, ears, lower legs and any pale areas are common places for sun-related skin irritation.
3. See whether the skin looks red, crusted, swollen, sore or warm, or whether there’s any discharge.
4. Check if your horse is rubbing, stamping, head shaking or avoiding touch on the affected areas.
5. Think about any recent changes in turnout, grazing, bedding, feed, supplements or topical products.
6. Look for signs of flies, mud, sweat or contact irritation that could also be affecting the skin.
7. Note whether the issue improves in shade or worsens after repeated sunny days.
Common Causes
Photosensitivity is a common possibility, especially when skin that’s already vulnerable is exposed to sunlight and becomes sore, crusty or scabby.
Sunburn on pale or unpigmented skin can also cause similar changes, particularly on the face and lower legs.
Skin irritation from plants, feed-related sensitivity, or contact with something in the environment may sometimes look much the same at first.
Less commonly, a skin infection or another underlying health issue may be involved, especially if the scabs keep coming back or spread.
What To Do
Try to reduce sun exposure while the skin settles, especially at the times of day when the sun is strongest.
Keep the affected areas clean and dry, and avoid picking scabs off, as that can make the skin more sore.
Check turnout, grazing and any recent changes in feed or topical products, since these can sometimes help point to a trigger.
Keep a simple note of when the scabs appear, where they are and whether they change with weather or turnout. That can be very helpful if you need to speak to your vet later.
If the skin is dirty or sweaty, a gentle wash routine may help support basic skin and coat hygiene, as long as the area isn’t raw or very painful.
Products That May Help
If your horse’s skin needs gentle routine care while you’re keeping an eye on the area, a suitable wash can be useful as part of a simple grooming routine.
