Bemotrizinol Is Coming to U.S. Sunscreens: What Every Rider Should Know

If you spend your days at the barn, in the ring, or traveling the show circuit, sun exposure is not an occasional concern. It is a daily, hours-long reality.

That is why a recent sunscreen development deserves the attention of equestrians. On June 9, 2026, the U.S. Food and Drug Administration added bemotrizinol to the list of permitted sunscreen active ingredients. It is the first new active ingredient added to the U.S. over-the-counter sunscreen monograph since the late 1990s. The FDA’s final order is scheduled to take effect on August 9, 2026.

Bemotrizinol will not change your sun-protection routine overnight, but it could eventually give riders access to sunscreens that combine strong broad-spectrum protection with lighter, more wearable formulations.

What is bemotrizinol?

Bemotrizinol, sometimes abbreviated as BEMT, is an organic ultraviolet filter that has been used in sunscreens internationally for many years.

The FDA reviewed clinical and nonclinical evidence and determined that bemotrizinol can be considered generally recognized as safe and effective when used under the conditions established in its final order. It may be used at concentrations of up to 6% in qualifying sunscreen products intended for adults and children six months of age and older.

In the United States, bemotrizinol will be supplied under the trade name PARSOL Shield by dsm-firmenich, a global ingredients company specializing in nutrition, health, and beauty. PARSOL Shield is the name of the active ingredient supplied to sunscreen manufacturers, not a finished sunscreen consumers can purchase.

Why bemotrizinol matters for riders

It provides broad-spectrum UV protection

Bemotrizinol absorbs both UVA and UVB radiation.

UVB radiation is closely associated with sunburn, while UVA exposure contributes to premature skin aging and can also play a role in skin cancer development. For riders who may spend an entire day outdoors, protection across both parts of the UV spectrum matters.

It is highly photostable

Bemotrizinol is valued for its ability to remain stable when exposed to sunlight. It does not break down as quickly as many existing organic sunscreen filters.

That could help formulators create consistent, effective broad-spectrum products. It does not, however, mean that a bemotrizinol sunscreen will last all day or eliminate the need for reapplication. Sunscreen can still be removed by sweat, water, toweling, clothing, and touching the face.

It may allow lighter, more elegant formulas

Because bemotrizinol absorbs ultraviolet radiation without producing the visible residue associated with some mineral filters, it may help manufacturers develop lightweight formulas that blend easily into a wide range of skin tones.

The ingredient also gives formulators more flexibility when creating lotions, creams, gels, sticks, and sprays. The experience of wearing the finished product will still depend on the entire formula, not just one ingredient.

Studies found minimal systemic absorption

The evidence evaluated by the FDA showed low systemic exposure and a favorable safety and tolerability profile under the permitted conditions of use. That is more precise than saying the ingredient remains completely on the skin’s surface, but it is one reason bemotrizinol has generated considerable interest.

Does this make today’s sunscreens obsolete?

No.

A well-formulated, broad-spectrum sunscreen that you apply correctly and consistently remains an essential part of sun protection. Mineral filters such as zinc oxide continue to provide effective broad-spectrum protection, and existing sunscreen products do not suddenly become ineffective because a new ingredient has been permitted.

Bemotrizinol simply gives formulators another tool. Over time, it may lead to more choices and more wearable products for consumers who have struggled with heaviness, visible residue, or other cosmetic concerns.

The sun-protection rules have not changed

Whether your sunscreen contains bemotrizinol, zinc oxide, or another permitted filter, the fundamentals remain the same.

Apply before you head outside

Apply sunscreen approximately 15 minutes before sun exposure and use enough to cover all exposed skin.

Reapply at least every two hours

Reapply more frequently when you are sweating, swimming, wiping your face, or removing and replacing equipment. A photostable ingredient does not make a sunscreen resistant to physical removal.

Look for broad-spectrum protection

A broad-spectrum sunscreen helps protect against both UVA and UVB radiation. SPF primarily reflects protection against sunburn-producing UVB radiation, so the words Broad Spectrum on the label matter.

Do not miss the rider-specific trouble spots

Pay particular attention to:

• The ears
• The hairline and exposed scalp
• The back and sides of the neck
• The nose
• The lips
• The hands
• Any skin exposed between clothing, gloves, and equipment

These areas are easy to overlook when you are getting yourself and your horse ready.

Keep sunscreen where you will use it

Keep sunscreen in your grooming bag, tack trunk, ring bag, or another convenient location. Avoid leaving the container in excessive heat, such as in your vehicle, or direct sunlight for extended periods, which can affect the product. 

What we will be watching

At Tull MD, we welcome responsible sunscreen innovation. Bemotrizinol appears to offer meaningful formulation advantages, particularly for people who need comfortable, broad-spectrum protection during long days outdoors.

We will be watching the first U.S. products closely, including how they perform in real-world conditions involving heat, sweat, movement, and repeated application.

For now, the most important advice remains simple: choose a broad-spectrum sunscreen you will use generously, carry it with you, and reapply throughout the day.

And do not forget your ears.
