Aquaphor Lip Repair + Protect Broad Spectrum SPF 30 Versus Carmex Daily Care Fresh Cherry SPF 15

In comedogenic testing, Beeswax scored a 0-2, which is on the low end. Whether or not a product clogs your pores really comes down to the formula as a whole (not any single ingredient on its own).

Cera Alba is the white, bleached form of this ingredient.

Just so you know, beeswax is not vegan since it is animal-derived. It cannot be removed with water, but can be taken off with an oil cleanser.

People with a known Propolis allergy also report to have reactions from beeswax.

Beeswax's wax esters are derived primarily from palmitic and oleic acid (C16 and C18:1). Both of these fall within the C11-C24 feeding window.

The Malassezia yeast can potentially cleave these esters and release usable fatty acids, so this ingredient may not be fungal acne safe. However, not everyone will react to this ingredient.

On concentrations:

So why did the EU cut back on how much you can use?

It comes down to absorption. Oxybenzone passes through skin more easily than other filters.

When the FDA tested sunscreens, every filter showed up in people's blood above the level where the agency wants extra safety testing done. But Oxybenzone showed up at by far the highest levels of the bunch.

To be clear, the FDA's point was that we need more research and not that the ingredient is dangerous. They also said to keep using sunscreen.

That high absorption, plus some animal studies pointing to effects on reproduction, is why EU regulators labeled Benzophenone-3 a hormone disruptor in 2025. An official classification is expected to follow in 2026.

It's also the most common photoallergen among sunscreen filters so it's a more frequent cause of contact/photoallergic dermatitis than most alternatives.

Places like Hawaii and Palau have also banned it over coral-reef concerns.

In formulas, it's always paired with a separate UVA filter because octinoxate solely protects skin from UVB.

Because it's an oil-soluble liquid, it's easy to blend into the oil phase of lotions/creams and gives a cosmetically elegant feel.

The one quirk about formulating this ingredient is photostability; the molecule slowly changes shape into a less effective version when sunlight hits it. So the longer you're in the sun, the weaker its protection gets. The drop can be more than 30% in some formulas.

It also doesn't play nice with Avobenzone (the common UVA filter) since avobenzone destabilizes octinoxate and the two degrade each other. But don't worry: brands have solved this issue by adding photostabilizers like Tinosorb S to prevent degradation and keep SPF stable under heavy UV exposure.

The maximum allowed level is 10% in the EU and Australia, 7.5% in the US and Canada, and 20% in Japan.

The Cosmetic Ingredient Review Panel has concluded this ingredient to be safe in cosmetics up to 10%.

One last thing worth knowing for context:

Octinoxate has been the subject of ongoing review in Europe where the Scientific Committee on Consumer Safety's (SCCS) 2025 final opinion is that this ingredient is an endocrine-active substance.

Lab and animal studies suggest it can act a bit like a hormone in the body (mildly mimicking estrogen and slightly blocking male hormones). It's important to know this hasn't really been shown to happen in everyday human use.

This ingredient is also banned in Hawaii over coral reef concerns.
