Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
Humectant, drawing moisture into the skin
Emollient, helping to soften skin
Solvent, dispersing and stabilizing formulas
Preservative booster, enhancing the antimicrobial activity of other preservatives
This ingredient is better known as bemotrizinol or Tinosorb S and is one of the best broad-spectrum UV filters in modern sunscreen.
It works by absorbing UV light across a whole range (280-400 nm) with peaks around 310 nm (UVB) and 340-345 nm (UVA). This means it covers UVB plus the deeper UVA wavelengths that drive photoaging and pigmentation.
Another pro?
It's exceptionally photostable, barely degrades in sunlight, and acts as a "bodyguard" for less stable filters.
That's why you'll see it paired with avobenzone or octinoxate; this team up ensures they keep working through sun exposure.
Safety reviews have been reassuring across the board. This ingredient shows low absorption through the skin, rarely irritates, and lab studies found it doesn't act like a hormone in the body (a concern that's been raised about some older sunscreen filters).
On maximum concentrations:
In 2026, the US F.D.A finally added it as an OTC sunscreen ingredient at concentrations up to 6% for adults / children 6 months and older
Polysilicone-15 (trade name: Parsol SLX) is a silicone-based UVB filter that soaks up UVB light (~280-320nm) with a peak around 310nm.
It's a fairly modest sunscreen filter so formulators mostly use it as an SPF booster and "light stabilizer". This just means it helps keep other light-sensitive ingredients from breaking down in sunlight.
A 2007 study measured the in-vitro SPF of 18 filters and found Polysilicone-15 contributed an SPF of about 3.64 at its maximum legal concentration (though worth noting its maker points out that in-vitro tests tend to underestimate its real performance because of its large polymeric structure).
Usage levels vary; it's approved up to 10% as a UV filter in the EU, China, Japan, Australia, ASEAN, and Mercosur countries. In the US, it's only permitted up to 1% as a light stabilizer because the FDA hasn't reviewed it as a sunscreen active.
Typical use levels range from 1-3%.
The EU's scientific committee concluded that this ingredient is safe for use as a UV absorber up to 10%, and tests came back negative for irritation, phototoxicity, and photoallergy.
There is one case of allergic lip inflammation from a lip balm with this ingredient, though this is rare.
Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.
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.
Silica, also known as silicon dioxide, is a naturally occurring mineral. It is used as a fine, spherical, and porous powder in cosmetics.
Though it has exfoliant properties, the function of silica varies depending on the product.
The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.
It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.
In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
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!
