Yes, Sunscreen can expire.  You read that right: Sunscreen can expire!

How long does sunscreen last?  Like anything else in your medicine cabinet. Sunscreen has a shelf life. Its ingredients naturally break down over time.  So, unless otherwise noted on the label, sunscreen lasts about three years.

Sunscreen products lose their effectiveness over time. Once expired, the active ingredients that protect against harmful UV rays may break down and no longer provide adequate sun protection. Applying expired sunscreen to a pot belly pig can create a false sense of protection, leaving their sensitive skin vulnerable to sunburn.

Pet pigs are especially susceptible to sunburn because they have sparse hair and light, delicate skin. Without proper protection, prolonged sun exposure can lead to painful burns, skin peeling, blistering, dehydration, and increased risk of skin damage over time. Severe sunburn may also cause stress, reduced appetite, and discomfort.

In addition, expired sunscreen may separate or degrade, potentially causing skin irritation or allergic reactions. The preservatives in the product may no longer be effective, which can increase the risk of bacterial contamination.

To protect pet pigs safely:

• Use only fresh, non-expired sunscreen
• Provide shade and limit sun exposure during peak UV hours (typically 10 a.m. to 4 p.m.).
• Reapply sunscreen as directed, especially after water exposure.

Taking these precautions helps ensure your pig remains comfortable, protected, and healthy in sunny conditions.
