Inside: Everything you need to know about sunscreen to be safe this summer. The differences between chemical vs mineral sunscreen, sunscreen expiration information and how long sunscreen lasts.
As I sit down to update this article about mineral sunscreen vs chemical sunscreen, it is 80 degrees, clear and perfectly sunny outside my house. We definitely need sunscreen today.
And, since it is still May, you may not have purchased new sunscreen yet for this year, so you’re wondering, “Does Sunscreen expire?” or “How long does sunscreen last?” and many other questions.
If you follow me on social media, you know that I’m a little freaked out about this chemical sunscreen thing. What chemical sunscreen thing, you ask?

Well, I’ll recap. Basically, researchers discovered that the chemicals that are in many of the sunscreens that we use are absorbed into the skin.
This can happen within 24 hours of applying. So, I am in the market for the best safe, chemical-free sunscreen for kids. Our summer fun depends on it! You can’t work on your summer bucket list if you don’t have sunscreen.
One researcher even stated: “When sunscreens were first evaluated by the FDA back in the ’70s, we all thought the ingredients sat on the surface of the skin and didn’t do anything,” says Dr. Theresa Michele, director of the division of nonprescription drug products in the office of new drugs at the Center for Drug Evaluation Research at the FDA. “But we’ve learned over the years that’s not actually the case, so we started looking at them more closely.”
Yikes! Since my kid refuses to wear a sun hat, we rely upon sunscreen.
What Sunscreens are Safe for Kids?
And, doctors from Children’s Hospital of Philadelphia said this: Pediatricians and dermatologists recommend using physical or mineral sunscreens (those with titanium dioxide or zinc oxide) with young children and anyone with dry skin or eczema. They also caution against using spray-application sunscreen, which might be inhaled.
As with anything, I am not a doctor nor do I play one on the internet. If you have concerns about your sunscreen, talk with your child’s pediatrician.
I bet many moms already use natural and organic sunscreen because their kids have sensitive skin, skin allergies or eczema.

Does Sunscreen Expire?
Yes, sunscreen can expire. Sunscreen typically has an expiration date printed on the packaging or bottle. The expiration date is usually determined by the U.S. Food and Drug Administration (FDA) requirement for sunscreens to be stable and effective for at least three years.
However, some sunscreens may have a shorter expiration period, especially if they contain certain ingredients that may degrade more quickly.
Using expired sunscreen is not recommended, as the effectiveness of the product may be compromised. Over time, the active ingredients in sunscreen can degrade, making the product less effective at protecting your skin from harmful UV rays.
Additionally, expired sunscreen may not spread evenly on the skin or may cause skin irritation.
To ensure adequate protection, it’s best to check the expiration date before using sunscreen. If the sunscreen has expired or if you’re unsure of its expiration date, it’s advisable to discard it and purchase a new one.
Remember to store sunscreen properly, away from direct sunlight and extreme temperatures, as this can help maintain its effectiveness for longer.

How Long Does Sunscreen Last?
The lifespan of sunscreen can vary depending on several factors, including the formulation, storage conditions, and the expiration date indicated on the product.
Generally, sunscreens are designed to remain effective for about three years from the date of manufacture, as mandated by the U.S. Food and Drug Administration (FDA).
However, it’s important to note that certain factors can affect the longevity of sunscreen:
- Expiration date: Check the date printed on the packaging or bottle. It indicates the time until which the sunscreen is guaranteed to be effective if stored properly.
- Storage conditions: Sunscreen should be stored in a cool, dry place and away from direct sunlight. Exposure to heat and excessive temperature fluctuations can accelerate the degradation of the product.
- Usage: The frequency of use and the amount of sunscreen applied can affect how long a bottle lasts. If you use sunscreen generously and frequently, you may need to replace it more often.
- Visible changes: Pay attention to any noticeable changes in the product’s texture, consistency, or odor. If the sunscreen appears clumpy, separated, or has an off smell, it’s best to discard it, regardless of the expiration date.
To ensure maximum sun protection, it’s recommended to use fresh sunscreen and reapply it as directed, especially after swimming, sweating, or extended sun exposure.
Remember that using expired sunscreen or inadequate sun protection can increase the risk of sunburn and skin damage.
Mineral Sunscreen vs Chemical Sunscreen
Mineral sunscreen and chemical sunscreen are two different types of sunscreens that provide sun protection through different mechanisms. Here’s an overview of their differences:
- Active Ingredients:
- Mineral Sunscreen: Mineral sunscreens use physical blockers, such as zinc oxide or titanium dioxide, as their active ingredients. These minerals work by sitting on the surface of the skin and reflecting or scattering UV rays away from the skin.
- Chemical Sunscreen: Chemical sunscreens contain organic compounds, such as avobenzone, oxybenzone, or octinoxate, as their active ingredients. These chemicals absorb UV rays and convert them into heat, which is then released from the skin.
- Application and Appearance:
- Mineral Sunscreen: Mineral sunscreens often leave a visible white cast on the skin due to the presence of zinc oxide or titanium dioxide. However, newer formulations have minimized this effect, and some mineral sunscreens now come in tinted options.
- Chemical Sunscreen: Chemical sunscreens are typically transparent and absorb into the skin more easily without leaving a white residue. They tend to have a thinner consistency, making them easier to spread.
- Sun Protection:
- Mineral Sunscreen: Mineral sunscreens provide broad-spectrum protection, meaning they protect against both UVA and UVB rays. They offer immediate protection upon application since they act as a physical barrier on the skin.
- Chemical Sunscreen: Chemical sunscreens also provide broad-spectrum protection, but their effectiveness may take some time to kick in, usually requiring about 20 minutes for the ingredients to fully absorb and provide optimal protection.
- Sensitivity and Allergies:
- Mineral Sunscreen: Mineral sunscreens are generally considered suitable for sensitive skin since they are less likely to cause irritation or allergic reactions. Zinc oxide and titanium dioxide are often used in baby sunscreens due to their gentle nature.
- Chemical Sunscreen: Some people with sensitive skin may experience skin irritation or allergies when using chemical sunscreens, particularly due to ingredients like oxybenzone. However, most individuals can use chemical sunscreens without any issues.
It’s worth noting that both mineral and chemical sunscreens have undergone safety testing and are considered effective for sun protection. The choice between them often comes down to personal preference, skin sensitivity, and desired application characteristics.
Ultimately, the most important aspect is to select a sunscreen that suits your needs and provides adequate protection against harmful UV rays.
Mineral Sunscreen that Doesn’t Have all that White to it
Let’s be honest–the reason we don’t use mineral sunscreens is because of how they look. They give you a whitish film or bluish color to your face that just isn’t appealing.
But, there are mineral sunscreens available in the market that are formulated to minimize the white cast typically associated with zinc oxide or titanium dioxide. Many brands have developed tinted mineral sunscreens or have incorporated iron oxides to help counteract the white appearance and blend more seamlessly with various skin tones.
These tinted mineral sunscreens can provide a more natural-looking finish.
Additionally, some mineral sunscreens now offer “sheer” or “invisible” formulations that have smaller particle sizes of zinc oxide or titanium dioxide. These smaller particles can reduce the visibility of the white cast, making them less noticeable on the skin.
When searching for mineral sunscreens with reduced white cast, look for terms like “tinted,” “sheer,” “invisible,” or “non-whitening” on the product labels or descriptions. It’s also helpful to read reviews or consult with a dermatologist or skincare professional for recommendations tailored to your skin type and complexion.
Remember that individual experiences can vary, and it’s a good idea to try out different options to find a mineral sunscreen that suits your preferences and provides effective sun protection without leaving a noticeable white residue on your skin.

Dangers of Chemical Sunscreen
If the CHOP doctors don’t convince you to switch to mineral sunscreen, maybe this will.
- Key West is banning sunscreens containing the chemicals oxybenzone and octinoxate due to the damage they’ve caused to coral reefs and ocean life.
- Hawaii has banned the same chemicals for the same reasons.
- Other countries including Palau, Mexico and Bonaire are doing the same.
- Some of these chemicals are known hormone/endocrine disruptors.( Endocrine disruptors are chemicals that can interfere with endocrine systems at certain doses. These disruptions can cause cancerous tumors, birth defects, and other developmental disorders. wiki )
- These active sunscreen chemicals have not been studied much, if at all.
- Many of our kids are medically complex, medically fragile, have different genetic makeup than the general public, and are on multiple medications. Is it dangerous? We just don’t know.
What sunscreen chemicals to avoid?
According to the website BanToxicSunscreens, these are the chemicals they say you should avoid. I’ve only read up on a few of them, but I am not using any sunscreen for my kids if it contains these chemicals.
Especially Kevin, since he is on multiple medications for his seizure disorder.
- Oxybenzone
- Octinoxate
- Octocrylene
- Homosalate
- Octisalate
- Avobenzone
- Parabens
