Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.
Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.
Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).
Learn more about Caprylyl GlycolDrometrizole Trisiloxane is an oil-soluble organic UV filter that L'oreal patented back in 1989.
Its offers broad-spectrum protection against UVB and UVA with two peaks: 303nm in the UVB range and 344 nm in the UVA range.
The standout trait is photostability. Unlike other UV filters, this one doesn't break down when exposed to sunlight.
You'll likely see it paired with Mexoryl SX (Ecamsule) because the two filters show a synergistic effect where the combined protection is greater than the sum of the individual filters.
Because it is oil soluble, it's great for water-resistant/sport/beach sunscreens.
Concentration-wise, the EU permits up to 15% but formulas use it well below that ceiling and almost never as a solo active.
It has a pretty solid safety record: allergic reactions are considered rare, its large molecule size means little to no absorption through skin, and toxicology reviews found no significant toxicity.
Just so you know, there were a handful of isolated allergic contact dermatitis case reports (which is true of every UV filter), but most people will not react to it.
This ingredient is available in the EU, Canada, Australia, and Japan, but not the US. This is just because the manufacturer hasn't pushed the data through the FDA's OTC ingredient pathway.
Learn more about Drometrizole TrisiloxaneEthylhexyl Triazone (aka Octyl Triazone) is an oil-soluble organic UVB filter. It has peak absorption around 314 nm, right in the middle of the UVB range.
This ingredient is described as one of the most effective UVB filters available and small concentrations are enough to deliver a high SPF thanks to its strong UV absorbing power.
Formulators love it for its stability; its ability to filter UV stays practically unchanged even under intense radiation and it can also help boost the photostability of less stable filters like avobenzone.
It's also a great pick for water resistant products because it's insoluble in water and has a good affinity for keratin.
Because it's a big, heavy molecule, the European Scientific Committee has found to to have very low dermal penetration and negative results for allergenicity.
In vitro testing also showed a low absorption rate and clean results on irritation.
Typical use levels are 1-5% with 5% being the maximum in the EU, Japan, and other markets that allow it. However, this ingredient is not approved yet in the US or Canada.

It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.
Learn more about PropanediolTocopherol is a fat-soluble antioxidant known as Vitamin E.
You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.

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!
