Packing sunscreen for a beach holiday feels automatic for most travellers. But in some of the world’s most popular coastal destinations, certain sunscreens are now being restricted because of concerns over damage to marine life. That means a product many people use every summer could become a problem depending on where they travel.
The changes are already happening in several tourist hotspots, particularly in places known for coral reefs and protected coastal areas. While nobody is being told to stop protecting their skin, authorities are starting to draw a line around which products are considered acceptable.
Why some sunscreens are causing concern
The issue is linked to chemicals found in many traditional sunscreens.
Ingredients such as oxybenzone, octinoxate and some parabens are commonly used in products designed to protect the skin from UV rays. Scientists and environmental groups have raised concerns for years about the effect these substances may have once they enter the sea.
When thousands of swimmers use sunscreen in the same area, traces of those chemicals wash into the water. In sensitive marine environments, especially around coral reefs, researchers say that can contribute to coral bleaching and damage fragile ecosystems.
That concern has pushed several destinations to act.
The idea is not to ban sun protection itself. The aim is to reduce the use of products considered more harmful to marine environments while encouraging alternatives seen as less damaging.
The beach destinations already changing the rules
Some of the best known holiday destinations have already introduced restrictions. Places in the Caribbean, parts of Mexico, Costa Rica and Hawaii have all adopted rules limiting certain sunscreens. In most cases, the focus is on protecting coral reefs and coastal ecosystems that attract large numbers of tourists every year.
Palau was one of the first countries to move in this direction when it introduced restrictions on reef damaging sunscreens in 2020. Since then, other tourist destinations have followed with their own versions of the rules.
The exact regulations vary from place to place. Some destinations ban specific ingredients. Others encourage visitors to switch to mineral based products instead.
For tourists, that means the same bottle of sunscreen that is perfectly acceptable at one beach may not be welcomed at another.
What travellers are being encouraged to use instead
As restrictions spread, reef friendly sunscreens are becoming easier to find.
These products usually rely on mineral ingredients such as zinc oxide or titanium dioxide rather than the chemical filters that have raised environmental concerns. They are often marketed as reef safe and are increasingly recommended in protected coastal areas.
Hotels, beach shops and pharmacies in affected destinations have also started adapting to the change, with more shelves dedicated to alternative products.
At the same time, another trend has started attracting attention online. Oral sun protection supplements are being promoted as an alternative way to protect the skin.
These products are often made using plant extracts such as Polypodium leucotomos and are marketed as helping reduce the effects of UV exposure.
Dermatologists, however, continue to warn that these supplements are not a replacement for sunscreen. They may offer additional support, but they do not provide complete protection against sunburn or long term sun damage.
That means travellers still need proper topical protection when spending time in the sun.
Why this matters more this summer
The timing is not accidental. As temperatures rise and beach tourism returns to peak season levels, destinations are once again facing huge numbers of visitors. Coastal authorities are under pressure to balance tourism with environmental protection, especially in areas where ecosystems are already vulnerable.
For many travellers, sunscreen restrictions may still sound surprising. After all, sunscreen has long been promoted as essential for preventing skin damage and reducing cancer risk.
That is why most destinations introducing restrictions are careful about how they communicate the rules. The message is not to stop using protection, but to choose products that are considered less harmful to the environment.
It also reflects a wider shift happening across tourism. More destinations are introducing rules linked to sustainability, from limits on cruise ships to tourist taxes and environmental protections.
Beach products are now part of that conversation too.
What tourists should do before travelling
For anyone planning a beach holiday this year, the safest option is to check local guidance before travelling.
Some destinations clearly list which ingredients are restricted and which types of sunscreen are recommended. Buying a suitable product before arriving can avoid confusion once you are there. Travellers should also remember that sun exposure remains a serious health issue, particularly during summer heatwaves.
The goal is not to avoid sunscreen, but to use products that protect both the skin and the environment where possible.
For many tourists, it will probably be the first time they think about what is actually inside the sunscreen they use. But with more destinations introducing restrictions, it is unlikely to be the last.
