Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
This ingredient is also known as oxybenzone, and is one of the older organic UV filters. Its main job is sitting in the oil phase and soaking up UV photons (primarily UVB with some short-wave UVA II range).
At low levels, oxybenzone also pulls double duty as a formula stabilizer that protects fragrance and colorants from fading in the light.
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.
Learn more about Benzophenone-3Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture.
Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%.
It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier.
Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%.
A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions.
Learn more about CarbomerCetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.
Its main roles are:
Though it has "alcohol" in the name, it is not related to denatured alcohol or ethyl alcohol.
The FDA allows products labeled "alcohol-free" to have fatty alcohols.
This ingredient may not be fungal acne safe. It is a primary fatty alcohol with a chain length above 12 carbons. A study from 2019 show Malassezia can feed on fatty alcohols in this range, so it may trigger fungal acne in those prone to it.
Learn more about Cetyl AlcoholDMDM Hydantoin has antimicrobial and antifungal properties. It is a preservative that works by slowly releasing formaldehyde over time.
So what's formaldehyde?
DMDM Hydantoin is approved for use in cosmetics all around the world.
In the EU, this ingredient is allowed in personal products up to 0.6 percent.
You might have heard of the class-action lawsuit about it causing hair loss. According to chemists, there has not been a link found between this ingredient and hair loss.
The Hydantoin part of this ingredient is created by reacting glycolic acid and urea.
You can check out alternatives to Dmdm Hydantoin:
phenoxyethanol, potassium sorbate, and sodium benzoate.
This ingredient is also known as Octinoxate and is one of the oldest and most widely used chemical UV filters in skincare.
It has a simple job: soap up UVB radiation (290-320 nm), the wavelengths responsible for sunburn and a big chunk of long-term sun damage.
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.
Learn more about Ethylhexyl MethoxycinnamateStearic Acid is a fatty acid that is already found in your skin. It's one of the free fatty acids that works alongside ceramides and cholesterols to maintain your barrier.
In cosmetics, it is a multitasker:
Safety-wise, the CIR Expert Panel has concluded it to be safe in cosmetics when formulated to be non-irritating and non-sensitizing.
Free stearic acid is a C18 fatty acid that the Malassezia yeast can substrate, so this ingredient may not be fungal acne safe.
Learn more about Stearic AcidTriethanolamine (TEA) is an emulsifier and pH adjuster. It is created using ethylene oxide and ammonia. This gives Triethanolamine a nitrogen core and a similar scent to ammonia.
As an emulsifier, it prevents ingredients from separating and enhances texture by adding volume to a product.
PH adjusters are common in cosmetic products. The pH of a product can affect the effectiveness of other ingredients. A product with a high pH may also irritate the skin.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
