How Heat Affects Your Sunscreen: What You Need to Know
Sunscreen is an essential part of sun protection, helping to shield your skin from harmful UV rays. However, did you know that how you store your sunscreen can impact its effectiveness? Heat exposure can degrade sunscreen over time, reducing its ability to protect your skin. Here’s what you need to know about keeping your sunscreen in top condition.
The Effects of Heat on Sunscreen
Sunscreens are formulated with active ingredients that absorb or reflect UV rays. However, prolonged exposure to high temperatures can break down these ingredients, making them less effective. Heat can also cause separation of the formula, leading to an uneven application and reduced protection.
Ideal Storage Conditions
To maintain its effectiveness, sunscreen should be stored in a cool, dry place, ideally below 30°C (86°F). Leaving it in direct sunlight, inside a hot car, or near heat sources can compromise the formula. Instead, consider keeping your sunscreen in a shaded area or inside a cooler bag if you're out in the sun for extended periods.

Signs Your Sunscreen May Be Compromised
If your sunscreen has been exposed to excessive heat, look out for these signs that it may no longer be effective:
Changes in texture (e.g., clumping or separation)
Unusual smell or discoloration
Expired expiration date
If you notice any of these signs, it's best to replace your sunscreen to ensure you’re getting the protection you need.
