Compromised skin and equine summer itch: the link
Itching problems are often approached from the perspective of insects or bites. However, not all horses react in the same way to summer aggressions. Some develop significant itching, lesions, or even chronic sores, while others go through the season without difficulty.
What if the key lies elsewhere?
What if the skin condition played a central role in the appearance and intensity of horse summer eczema? To learn all about this condition, consult our complete guide to horse summer eczema.
What is fragile skin in horses?
The skin is not just a simple covering. It is a living organ, with several essential functions:
- a protective barrier against external aggressions,
- moisture regulation,
- protection against microorganisms,
- participation in local immune reactions.
Fragile skin is when this natural barrier no longer fully plays its role. This can result in:
- dry skin or, conversely, excessively moist skin,
- loss of elasticity,
- micro-lesions invisible to the naked eye,
- increased sensitivity to friction and bites,
- slower healing.
Fragile skin reacts more strongly, more quickly… and for longer.
Why does skin become fragile over the seasons?
In horses, several factors contribute to skin fragility, sometimes well before the first signs of summer eczema appear.
Environmental aggressions
- repeated humidity,
- stagnant sweat,
- mud,
- dust,
- friction from equipment or blankets.
Inappropriate or excessive care
- too frequent washing,
- harsh or drying products,
- alternating multiple solutions without giving the skin time to regenerate.
Mechanical aggressions
- repeated scratching,
- friction against fences, trees, or shelters,
- hair pulling that creates new entry points.
Gradually, the skin loses its natural balance. It becomes more reactive and less able to defend itself.
Why does fragile skin promote summer eczema?
When the skin is healthy, an insect bite can remain harmless.
When the skin is fragile, this same bite can trigger:
- a more intense inflammatory reaction,
- persistent itching,
- lesions that become established,
- a vicious cycle of scratching → sores → superinfection → slow healing.
Summer eczema is then no longer solely linked to insects, but to the skin's inability to play its protective role.
It is for this reason that some horses continue to suffer despite the use of repellents or solutions supposed to be remedies: the root cause, the condition of the skin, is not truly taken into account.
Sanitizing and strengthening the skin: a complementary approach
Rather than seeking only to mask the symptoms, it is essential to restore healthy and balanced skin.
Sanitizing the skin allows to:
- limit the proliferation of undesirable microorganisms,
- promote a more stable skin environment,
- support natural repair mechanisms.
- Strengthening the skin means giving it back the means to defend itself against summer aggressions.

The benefit of Ozone Soin Peau ozonated oil
Ozonated oil Ozone Soin Peau is part of this logic of skin support in natural products for animals.
Thanks to the action of stabilized ozone in a vegetable oil, it allows to:
- gently sanitize the skin,
- support skin regeneration,
- strengthen the skin's natural barrier,
- accompany the healing of fragile areas.
It does not position itself as an aggressive solution, but as a deep treatment, useful when the skin is already sensitized or to prevent small lesions from becoming permanently established.
In a global treatment approach, it finds its place to help the skin regain a more balanced function.
"Quickly soothes itching.
Very little odor (my mare being very sensitive to this parameter, she didn't grumble when I applied it).
The applicator tip is nice, allows to target the area to be treated.
I recommend!" Camille T
If you need to treat a weeping or bleeding lesion, prefer to use Ozone Soin Intensif first.
Healthy skin, a calmer horse
Summer eczema in horses is not limited to a simple reaction to insect bites. It often reflects fragile skin, struggling with repeated environmental aggressions.
Taking care of the skin, sanitizing and strengthening it, means acting at the source of the problem and offering the horse better conditions to get through the summer season.

❓ FAQ – Summer eczema and horse skin
Why does fragile skin promote summer eczema in horses?
Fragile skin performs its protective barrier role less effectively. Insect bites, rubbing, or humidity then cause more significant inflammatory reactions, promoting itching, lesions, and the establishment of summer eczema in horses.
Is a summer eczema product sufficient if the skin is already damaged?
A summer eczema product can provide temporary relief, but it is not always sufficient when the skin is fragile. Without sanitizing and strengthening the skin, recurrences are frequent and healing remains slow.
What is the role of ozonated oil in a treatment approach for summer eczema in horses?
Ozonated oil is used to sanitize the skin and support its natural regeneration. It helps strengthen the skin barrier, making it a relevant complementary treatment in a global approach to treating summer eczema in horses.
