Neutrogena UltraSheer Face & Body Stick Sunscreen SPF 70 Versus Shiseido Clear Stick UV Protector WetForce Broad Spectrum Sunscreen SPF 50+

Studies have found that avobenzone becomes ineffective when exposed to UV light (it is not photostable; meaning that it breaks down in sunlight). Because of this, formulations that include avobenzone will usually contain stabilizers such as octocrylene.

However, some modern formulations (looking at you, EU!) are able to stabilize avobenzone by coating the molecules.

Avobenzone does not protect against the UV-B range, so it's important to check that the sunscreen you're using contains other UV filters that do!

The highest concentration of avobenzone permitted is 3% in the US, and 5% in the EU.

Ongoing research is looking into whether oxybenzone causes skin irritation and sensitivity. However, it has been shown to trigger contact dermatitis in some studies.

Oxybenzone is allowed in certain concentrations by many countries. It is allowed up to 6% in the US, and Canada, 5% in Japan, and 10% in Australia. Other countries and regions of the US have banned this ingredient to protect coral reefs and marine ecosystems. These places include Hawaii, Key West, US Virgin Islands, marine parks in Thailand, Aruba, and Palau.

The EU currently allows the following maximum concentrations:

Studies show conflicting results about oxybenzone being absorbed into the human body. The Swedish Research Institute has advised careful use of this ingredient by pregnant women and children. We always recommend speaking with a professional if you have concerns about this ingredient and your health.

As a preservative, it is used to stabilize products and prevent them from degrading. Specifically, BHT prevents degradation from oxidation.

The concerns related to BHT come from oral studies; this ingredient is currently allowed for use by both the FDA and EU.

However, it was recently restricted for use in the UK as of April 2024.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
