Sunscreen without fragrance and endocrine disruptors: what you need to know
You apply sunscreen daily, by the handful, over a large part of your body. No other cosmetic product ends up on your skin in such quantities. That makes what's in your tube more important than you might think.
What's actually in your sunscreen?
Open any tube of sunscreen and you'll quickly find dozens of different ingredients on the packaging. A few of them do the real work: the UV filters. The rest are additives, such as preservatives, fragrances and emulsifiers.
The problem lies with a specific group of substances found in many of those ingredients: endocrine disruptors. And you'd rather not apply those to your skin every day.
What are endocrine disruptors?
Endocrine disruptors are chemicals that behave like natural hormones in your body. They can affect your hormone system, with possible effects on fertility, thyroid function and even children's pubertal development.
The World Health Organization (WHO) recognises endocrine disruptors as a serious public health concern. They're not only found in sunscreen: you also find them in plastic packaging, food and cleaning products. But cosmetics are one of the biggest sources of daily exposure, precisely because we apply these products to large areas of skin.
Which ingredients should you avoid in sunscreen?
Not every ingredient is a problem. But these three groups deserve a critical eye.
Parabens vs. chemical UV filters
The two biggest categories to watch out for, side by side:
|
Parabens |
Chemical UV filters |
|
|---|---|---|
|
What is it? |
Preservative used in cosmetics |
UV filter that absorbs radiation |
|
What's the problem? |
Linked to hormone disruption and fertility problems |
Penetrate the skin; detected in blood, urine and even breast milk |
|
On your label |
methylparaben, propylparaben, butylparaben, ethylparaben |
oxybenzone, octinoxate, octocrylene |
|
Rule of thumb |
Ends in "-paraben"? Don't buy it. |
Long chemical names on the UV filter line? Go for mineral instead. |
|
Good to know |
Also found in shampoo, shower gel and body lotion |
Oxybenzone is banned in Hawaii and Palau because of damage to coral reefs |
A sunscreen without parabens and without chemical UV filters is therefore a double win: no endocrine disruptors, and no substances that end up in your bloodstream.
Other ingredients to avoid
You'd rather not see these names on your label either:
-
Benzophenones (BP-1, BP-2, BP-3): endocrine-disrupting properties
-
Phthalates (DEP, DMP): often hidden under the collective term "fragrance"
-
Artificial fragrances and preservatives: higher risk of irritation, little function
-
Expired sunscreen: degraded chemical filters become even more harmful than they already were. So always check the expiry date.

So what should you use instead?
A sunscreen without the chemicals you'd rather avoid? That's perfectly possible. The alternative is called mineral sunscreen.
What makes a good mineral sunscreen?
-
Non-nano zinc oxide as the active UV filter. It works as a physical barrier on your skin, doesn't penetrate and is safe for both skin and the environment.
-
Short ingredient list. The fewer, the better. A list you can take in at a glance is almost always a good sign.
-
Independent certifications such as the EU Ecolabel.
The WONDR Mineral Sunscreen SPF 30 ticks all these boxes: non-nano zinc oxide as the only UV filter, no parabens, no chemical filters, no endocrine disruptors. Complemented with sunflower oil, shea butter and aloe vera for care, and vitamins E and C for antioxidant protection.
Better for your skin, better for the planet. Handy, right?
Who is this especially important for?
A sunscreen without harmful substances is a good idea for everyone. But for these groups, it really matters:
-
Pregnant and breastfeeding women. Substances that enter your bloodstream also reach your baby.
-
Young children. Their skin is thinner and more sensitive, and substances are absorbed faster than in adults.
-
People with sensitive skin or hormone problems. A weakened skin barrier lets more ingredients through, and with hormone-related conditions you want to avoid every extra trigger.
-
Anyone who uses sunscreen daily as a day cream. Cumulative exposure adds up. What you put on your face 365 days a year is something you need to be able to trust.
How do you read an ingredient list?
Good news: you don't need to be a chemist to read an ingredient list. Four simple rules.
-
Order = concentration. The first ingredients are present in the largest amounts. So pay most attention to what's at the top.
-
Find the active UV filter. Zinc oxide or titanium dioxide = mineral. Oxybenzone, octinoxate or octocrylene = chemical.
-
Scan for "paraben". Does an ingredient end in these letters? Don't buy it.
-
Avoid long lists with unrecognisable names. A tube with thirty ingredients, twenty-five of which you can't pronounce, is rarely a good choice.
Short, readable ingredient list? In 9 out of 10 cases, a safe choice.
