After recent recalls and growing concern over sunscreen
reliability, many people are asking the same question: how can we choose a
sunscreen that is both safe and effective?
What is SPF?
The most important guide to choosing a sunscreen is its SPF
rating SPF – sun protection factor – is a measure of how well the sunscreen
filters the damaging UV radiation. Health experts around the world generally
recommend we all choose sunscreens with three important features:
1. An SPF of 50+ which is the maximum protection rating
2. Broad-spectrum coverage, which shields against both UVA
(aging) and UVB (burning) rays.
3. A sunscreen that is water resistant to maintain
protection during physical work, sports, or time outdoors.
Why have some sunscreens been recalled?
In 2025, independent testing in several countries found that
some sunscreens offered much less protection than their labels claimed.
Products marked as SPF 50+ were found to have significantly lower ratings, with
some performing as low as SPF 4. This led to several recalls and raised
questions about testing standards and product reliability.
Many of these products shared the same base formula, with
different companies adding their own fragrances and branding. Some of the
testing laboratories involved were also found to have gaps in their
verification processes.
To stay informed, check your local health authority’s
website for updated recall information before purchasing sunscreen.
Which is better �� a mineral or chemical sunscreen?
If you choose a broad-spectrum, water-resistant sunscreen
with SPF 50+, both mineral and chemical types can provide strong protection.
Mineral sunscreens (made with zinc oxide or titanium
dioxide) sit on top of the skin and block UV rays. They work immediately, are
often better for sensitive skin, and are more environmentally friendly, but may
leave a slight white layer on the skin.
Chemical sunscreens absorb into the skin and neutralize UV
rays. They should be applied about 20 minutes before sun exposure and have a
clear, invisible finish.
The takeaway
Choose a sunscreen that offers SPF 50+ broad-spectrum
protection, check for any safety alerts, and reapply regularly, especially
after sweating, swimming, or towel-drying. Consistent protection helps prevent
sun damage, premature aging, and skin cancer.
