Not all sunscreens are created equal, especially when you’re working up a sweat outdoors. Whether running, swimming, or practicing yoga under the sun, choosing the right sunscreen can make a big difference in your comfort and protection.
In this Q&A, Dr. Emily Cai, MD, a board-certified dermatologist, answers some of the most common questions about picking the best sunscreen for exercise and shares a few of her top recommendations.
Q: What makes a sunscreen ideal for exercise versus beach lounging?
A: When exercising outdoors, it's essential to look for sunscreen formulated explicitly for sports or active wear. These products are often labeled "sweat-resistant" or "water-resistant," meaning they’re less likely to wash off with perspiration or water exposure. This ensures more consistent protection throughout your activity. In contrast, a standard sunscreen for the beach may not hold up as well during vigorous movement or heavy sweating.
Q: What happens if I don’t wear sunscreen while exercising outside?
A: Exercising without SPF leaves your skin vulnerable to sunburn and long-term ultraviolet (UV) damage. Chronic UV exposure increases the risk of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma. Additionally, UV rays accelerate signs of aging, such as discoloration, fine lines, and wrinkles—damage that can be prevented with consistent sun protection.
Q: What are the pros and cons of mineral vs. chemical sunscreens for exercise?
A: Mineral sunscreens, which use zinc oxide or titanium dioxide, tend to be gentler on sensitive skin and are less likely to cause irritation or stinging, especially around the eyes when sweating. However, they may feel thicker or leave a white cast, which some users find less comfortable during physical activity.
Chemical sunscreens, on the other hand, are often more lightweight and easier to apply without residue. However, they may cause burning or stinging in sensitive individuals, particularly if they migrate into the eyes during a workout.
Q: What ingredients and SPF level should I look for in an exercise sunscreen?
A: I recommend choosing a broad-spectrum sunscreen, which protects against UVA (aging rays) and UVB (burning rays). For mineral sunscreens, look for zinc oxide or titanium dioxide. Aim for a minimum SPF of 30, though higher SPFs can offer added peace of mind during prolonged outdoor activity. It’s also essential to reapply sunscreen every 40 to 90 minutes, particularly if you’re sweating heavily or swimming.
Q: What are some sunscreen products you recommend for exercise?
A: I’ve personally used and recommend the following options for active wear:
- Neutrogena Sport Face Sunscreen SPF 70+ – Lightweight, high SPF, and designed for intense activity.
- Dermalogica Invisible Physical Defense Mineral Sunscreen SPF 30 – A mineral-based option that blends well and feels comfortable on the skin.
- La Roche-Posay Anthelios UV Pro-Sport SPF 50 – Reliable broad-spectrum protection with a smooth, wearable texture.
Q: Are there any other tips for choosing the best workout sunscreen?
A: The best sunscreen is one you'll use and reapply. Choose a product with a good texture and formula for your skin—a gel, lotion, stick, or spray. Finding a product you like will increase your likelihood of using it consistently, which is the most critical factor in protecting your skin during outdoor exercise.
