Ensuring the effectiveness of your Obagi Nu-Derm Physical UV Block SPF 32 starts with proper storage and handling. This sunscreen, designed to protect your skin from harmful UV rays, needs to be treated with care to maintain its potency.
Store your Obagi Nu-Derm Physical UV Block SPF 32 in a cool, dry place away from direct sunlight. The ideal temperature range is between 68°F and 77°F (20°C to 25°C). Avoid storing it in places like your car's glove compartment or bathroom, where temperatures can fluctuate significantly.
When using the product, make sure your hands are clean to prevent contamination. I always shake the bottle well before application to ensure the ingredients are evenly mixed. Apply a generous amount to ensure full coverage, and reapply every two hours, or after swimming or sweating, as recommended by the Skin Cancer Foundation.
Check the expiration date on your Obagi Nu-Derm Physical UV Block SPF 32 before use. Sunscreens typically have a shelf life of about three years from the date of manufacture, but once opened, they should be used within a year for optimal efficacy. Based on available research, individual results may vary, and if you notice any changes in the product's color, texture, or smell, it's best to discard it.
When traveling, keep your Obagi Nu-Derm Physical UV Block SPF 32 in your carry-on luggage to maintain control over its storage conditions. I've found that using a travel-sized container can be convenient, but be sure to transfer the sunscreen into a clean, airtight container to prevent contamination.
By following these simple yet effective storage and handling practices, you can ensure that your Obagi Nu-Derm Physical UV Block SPF 32 remains a reliable shield against UV damage. Remember, while these tips are based on trusted sources, always consult with a healthcare professional for personalized advice on skin care products.
