6 Best Horse Sunscreen For Sensitive Noses Without Harsh Chemicals
Protect your horse’s sensitive nose from sunburn. Our guide reviews 6 top sunscreens made without harsh chemicals, perfect for delicate equine skin.
You turn your horse out on a sunny morning and notice it again: that bright pink nose is looking a little too pink. By evening, it’s tender, peeling, and clearly uncomfortable. For owners of horses with chrome, bald faces, or light-skinned muzzles, sunburn is a constant, nagging concern. Finding a solution that works without irritating sensitive skin or using harsh chemicals is key to keeping them comfortable all summer long.

Protecting Sensitive Equine Skin From Sunburn
A horse’s nose is one of its most vulnerable areas to the sun. The skin is thin, hair is sparse, and breeds with pink skin—like Paints, Appaloosas, and Cremellos—lack the melanin needed for natural protection. This isn’t just a cosmetic issue. Sunburn causes real pain, peeling, and can lead to a horse becoming head-shy or resistant to haltering.
Repeated, severe burns can also lead to more serious problems. Chronic sun exposure can increase the risk of skin cancers like squamous cell carcinoma, especially around the eyes and muzzle. In some cases, what looks like a simple sunburn can be a sign of photosensitivity, an inflammatory reaction triggered by sunlight after the horse ingests certain plants. The bottom line is that a physical barrier is the most reliable defense.
Equiderma Zinc Paste: Soothing Sun Protection
Equiderma’s Zinc Paste is a heavy-hitter in the sun protection world. It’s less of a cream and more of a thick, durable paste, which is exactly what you want for all-day staying power. The primary ingredient is zinc oxide, a mineral that creates a physical barrier, reflecting harmful UVA and UVB rays away from the skin.
What sets this one apart is its formulation. It’s not just zinc; it’s combined with soothing ingredients like neem oil and shea butter. This makes it a great choice for skin that’s already a bit irritated or chapped. The paste is very white and very visible, which means you know exactly where it is and when it needs a touch-up. It’s not subtle, but when it comes to pure protection, effectiveness often trumps aesthetics.
My Pony Sunscreen: An All-Natural Nose Guard
For those who prioritize clean, simple ingredients, My Pony Sunscreen is a fantastic option. It’s specifically designed for equine faces with a formula that often includes non-nano zinc oxide, red raspberry seed oil, and other plant-based butters. The term "non-nano" is important here; it means the zinc particles are too large to be absorbed into the bloodstream, sitting on top of the skin to do their job.
This product feels more like a thick balm than a sticky paste. It goes on smoothly and smells pleasant, which can make the daily application process a little easier for both you and your horse. The tradeoff for its gentle, all-natural formula is that it may require more frequent reapplication, especially if your horse is a messy drinker or sweats a lot. It’s a perfect choice for daily, moderate sun exposure.
Coat Defense Paste: A Multi-Purpose Sunblock
Coat Defense Paste is a staple in many grooming kits, but not always for sun protection. Its primary use is often to treat fungal and bacterial skin issues like scratches or rain rot, thanks to its proprietary blend of clays and minerals. However, those same ingredients—particularly the zinc oxide and bentonite clay—make it a surprisingly effective sunblock.
This is the ultimate multi-tasker. If you already have it on hand for skin funk, you have a ready-made sunblock. It creates a dry, powdery barrier that stays put remarkably well and can even help dry up weepy, irritated skin. The texture is different from a traditional cream, so it might take some getting used to. But for a hobby farmer looking to get more mileage out of a single product, it’s a smart, practical choice.
Epi-Pet Sun Protector: A Vet-Approved Option
When you’re looking for a product backed by scientific formulation, Epi-Pet is a name that frequently comes up. It’s one of the few sunscreens for pets that has gone through the rigorous process to be considered FDA-compliant, which offers a significant level of peace of mind regarding safety and efficacy. It’s often recommended by veterinarians for this reason.
Epi-Pet typically comes in a non-aerosol spray bottle. While spraying anything near a horse’s face is a bad idea, the application is simple: spray it onto your gloved hand and wipe it on. The formula is non-greasy and water-resistant, providing broad-spectrum protection. This is a great choice if you want a vet-approved, tested product and don’t mind the spray-to-hand application method.
Desitin Diaper Cream: The Farmer’s Go-To Hack
Walk into almost any barn, and you’ll probably find a tube of Desitin in a grooming tote. This classic diaper rash cream has been an off-label go-to for horse owners for decades, and for good reason: it works. The active ingredient is a high concentration of zinc oxide, the very same mineral found in expensive equine sunscreens.
The key is to buy the Maximum Strength version, which contains 40% zinc oxide. It’s cheap, widely available, and creates an incredibly durable, waterproof barrier that lasts for hours. The downside? It’s thick, greasy, and can be messy to apply. You also need to read the label, as some formulas contain ingredients like cod liver oil or heavy fragrances that might not be ideal for every horse. Still, for sheer cost-effectiveness and barrier strength, it’s hard to beat.
Shire’s Bio-C-Lotion for Very Sensitive Skin
Sometimes, a standard sunblock isn’t enough, especially for horses with chronic skin issues or photosensitivity. Shire’s Bio-C-Lotion is a specialized product designed to soothe and protect extremely irritated skin. While not marketed exclusively as a sunscreen, its formula creates a protective barrier that helps shield compromised skin from sun, flies, and other environmental irritants.
This lotion contains ingredients like benzyl benzoate and lanolin, which are known for their soothing and protective qualities. It’s an excellent choice for a horse whose nose is already raw, peeling, or dealing with issues like pastern dermatitis that extends onto the muzzle. Think of it less as a preventative sunscreen and more as a therapeutic lotion that also provides a physical barrier. It’s a targeted solution for the most difficult cases.
Key Ingredients and Application Best Practices
No matter which product you choose, the principles of protection remain the same. The most effective and gentle sunscreens for horses rely on mineral-based physical blockers, not chemical ones. The gold standard is Zinc Oxide, a stable mineral that provides broad-spectrum protection against both UVA and UVB rays without being absorbed into the skin. Titanium dioxide is another common mineral blocker that works similarly.
To get the most out of any product, proper application is crucial. A few best practices can make all the difference.
- Start with a clean, dry surface. Wipe any dirt or moisture off the nose before applying.
- Apply a thick, even layer. You want to see a visible coating. This is a physical barrier, so more is more.
- Don’t forget other vulnerable spots. The tips of the ears, white-rimmed eyes, and any white leg markings below the knee can also burn.
- Reapply as needed. Sunscreen isn’t a one-and-done solution. Reapply after heavy rain, if your horse has been sweating profusely, or after they’ve had a long drink and dunked their nose in the water trough. A quick check in the afternoon is always a good idea.
Ultimately, protecting your horse’s sensitive nose is a simple act of daily management that pays huge dividends in their comfort and long-term health. Whether you choose a purpose-built equine product, a multi-use paste, or a trusted barn hack, the best sunscreen is the one you’ll actually use consistently. By finding the right fit for your horse and your routine, you can ensure they enjoy sunny days without the painful consequences.
