6 Horse Sunscreens For Sensitive Areas Without Harsh Chemicals

You turn your horse out on a sunny morning and notice the pink skin on their muzzle is looking a little too pink. By evening, it’s tender, red, and clearly uncomfortable. Just like us, horses with light-colored or sensitive skin are susceptible to sunburn, which can lead to pain, peeling, and more serious long-term issues.

Why Your Horse Needs Sunscreen on Sensitive Skin

Some horses are simply more prone to sunburn than others. Those with pink skin, particularly on the muzzle, around the eyes, and on the tips of their ears, are at the highest risk. White markings, like blazes or socks on pink-skinned legs, and areas with thin hair from scarring or rubs are also vulnerable spots.

A sunburn isn’t just a cosmetic issue; it’s painful. It can cause the skin to blister and peel, making the horse head-shy or resistant to wearing a halter or bridle. Repeated, severe burns can lead to chronic skin problems, increase susceptibility to infections, and even contribute to conditions like photosensitization, where the skin becomes abnormally reactive to sunlight due to certain plants or liver issues.

The key is choosing the right kind of protection. Many human sunscreens contain chemicals like oxybenzone, which can be irritating to a horse’s already sensitive skin. That’s why we’re focusing on physical, mineral-based sunblocks, primarily those using zinc oxide. These products form a physical barrier on the skin, reflecting UV rays rather than absorbing them, which is a much gentler approach for delicate areas.

Equiderma Zinc Oxide Paste for Max Protection

When you need heavy-duty, no-nonsense protection, Equiderma’s paste is the go-to. This isn’t a subtle lotion; it’s a thick, opaque white paste that creates a complete physical block against the sun. Its high concentration of zinc oxide means it offers some of the most powerful and lasting protection you can find.

The major benefit is its staying power. You apply it in the morning, and you can be confident it’s still there hours later, even through grazing and a bit of sweating. It’s designed to adhere to the skin and not easily rub off. Think of it as armor for your horse’s most sensitive spots, especially that delicate muzzle that’s always in the sun.

The tradeoff, of course, is aesthetics. It is very white and very visible. This isn’t the product you use before a show, but for daily turnout, its effectiveness is hard to beat. If your horse has a history of severe sunburn and you need a reliable solution that works all day, this is your product.

Zephyr’s Garden Solar Shield: An Herbal Choice

Zephyr’s Garden takes a slightly different approach, blending the protective power of zinc oxide with a mix of soothing, herbal ingredients. You’ll often find things like shea butter, calendula, and red raspberry seed oil in their formulas. This combination provides a dual benefit: it shields the skin from new sun damage while actively calming existing irritation.

This makes it an excellent choice for a horse whose nose is already a little pink and tender. Instead of just slathering a barrier on top of irritated skin, you’re applying something that helps heal and protect at the same time. The texture is typically creamier and more spreadable than pure zinc paste, making application a bit more pleasant for both you and your horse.

Consider this the holistic option. It’s for the owner who wants effective sun protection but also values the skin-conditioning benefits of natural botanicals. If your horse’s skin is generally reactive or you want to manage minor redness before it becomes a real burn, an herbal-based shield is a fantastic tool.

My Pony Sun Block for Targeted Muzzle Coverage

My Pony Sun Block is all about practical, easy application. It often comes in a stick form, like a giant lip balm, which is perfect for swiping directly onto a horse’s muzzle without getting your hands messy. Many of their formulas are brightly colored—think pink or blue—which serves a very practical purpose.

That bright color isn’t just for fun. It lets you see exactly where you’ve applied the sunblock and, more importantly, when it has worn off. A quick glance from the pasture gate tells you if your horse needs a reapplication. This visual cue is incredibly helpful for busy owners managing multiple animals.

The formula is designed to be non-greasy and stick well, even on an area that’s constantly moving while grazing and drinking. It’s the ultimate convenience product for targeted protection. If you need a quick, reliable, and easy-to-monitor solution for daily muzzle care, this is it.

Farnam SWAT Clear: Sunblock and Fly Repellent

Everyone knows SWAT as the classic pink ointment for keeping flies out of wounds and away from sensitive eyes and ears. The clear version of this barn staple offers a brilliant two-for-one benefit: it repels flies and contains sunscreen. This makes it an incredibly efficient addition to your daily grooming routine.

By applying it around the eyes, ears, and muzzle, you’re addressing two of summer’s biggest annoyances in a single step. The clear formula is also much less conspicuous than the original pink version, which is a nice bonus for everyday use. It’s a workhorse product that solves multiple problems at once.

The key consideration here is that it’s a multi-tasker. While it provides sun protection, it may not be as potent as a dedicated, high-zinc-oxide paste. It’s best for horses needing mild to moderate sun protection in areas that are also pestered by flies. For a horse with an extremely sensitive, easily burned nose, you might still need a heavier block, but for general protection and fly control, SWAT Clear is hard to beat for convenience.

Lucky Braids Handy Salve for Soothing Relief

This product fits into a different category. It’s less of a dedicated sunscreen and more of an all-purpose skin salve that happens to offer sun protection as one of its many benefits. Formulated with ingredients like beeswax and lanolin, its primary mission is to soothe, heal, and condition the skin.

Think of it as your first-aid-kit-in-a-jar. It’s fantastic for treating minor scrapes, bug bites, dry patches, and existing sunburn. The natural barrier created by the salve’s ingredients also provides a gentle layer of protection against further sun exposure, helping the skin heal without being re-damaged.

The Handy Salve is the ideal choice for a horse with generally sensitive skin that’s prone to all sorts of minor irritations. If you’re dealing with a bit of sunburn on top of a scratch or some flaky skin, this product tackles it all. It simplifies your approach by combining healing and protection into one gentle, effective formula.

Happy Horse Sunscreen: A Gentle, Natural Balm

For the owner who reads every ingredient label, a simple, natural balm is often the best fit. Products like those from Happy Horse focus on a short list of recognizable, gentle ingredients: non-nano zinc oxide, shea butter, coconut oil, and other natural oils. There are no synthetic chemicals, fragrances, or preservatives to worry about.

This approach is perfect for horses with known skin allergies or extremely reactive skin. The non-nano zinc oxide is key—it means the particles are too large to be absorbed into the bloodstream, sitting on top of the skin to form a safe, physical barrier. The balm-like consistency makes it easy to apply and helps moisturize the skin at the same time.

This is the minimalist’s choice. It provides effective, straightforward sun protection without any of the extras that might cause a reaction. If your philosophy is "less is more" when it comes to what you put on your horse, a gentle, natural balm is the perfect solution.

Applying Sunscreen for All-Day Effectiveness

Simply dabbing on some sunscreen in the morning isn’t enough to guarantee protection. Proper application is just as important as the product you choose. Start with a clean, dry surface. Wiping your horse’s muzzle with a soft cloth to remove dirt and moisture will help the sunscreen adhere better and last longer.

No sunscreen is truly waterproof or rub-proof, especially on a horse. Be prepared to reapply. A horse that dunks its nose in the water trough or loves to rub its face on its legs will need a second application in the afternoon. The colored sunblocks are great for this, as they give you an obvious visual cue when it’s time for more.

Before you commit to a new product, always do a patch test. Apply a small amount to a less sensitive area, like the side of the neck, and wait 24 hours to check for any signs of irritation or allergic reaction. Even the most natural products can cause issues for a particularly sensitive horse.

Remember that sunscreen is just one tool in your toolbox. A fly mask with a long nose flap can provide excellent physical protection without the need for reapplication. If possible, providing access to shade or adjusting turnout schedules to avoid the most intense midday sun (typically 10 a.m. to 4 p.m.) will make the biggest difference of all.

Ultimately, protecting your horse from the sun is about finding the right balance for your specific situation. By matching your horse’s skin sensitivity and your daily routine to a product’s strengths, you can easily keep them comfortable and safe all summer long.
