Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Ethylhexyl Methoxycinnamate is an organic compound that provides UVB protection. It often goes by the more common name of octinoxate. It is created from methoxycinnamic acid and 2-ethylhexanol.
Ethylhexyl Methoxycinnamate absorbs UVB rays with wavelengths between 280-320 nm. UV absorbers protect your skin by using chemical reactions to convert UV rays into heat and energy.
UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA, causing sunburns and are thought to be linked to skin cancer.
The state of Hawaii has banned sunscreens containing octinoxate due to its potential impact on coral reefs. More research is needed to bridge gaps in this research. The European Union allows higher levels of octinoxate in sunscreens than the US and Australia.
Ethylhexyl Methoxycinnamate is oil soluble. It is not stable and may lose efficacy when exposed to sunlight.

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. Stay hydrated!
Learn more about WaterPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

This was the first product by EltaMD I ever used, and overall my experience was good through three months of use. This SPF in particular is a dual chemical/physical filter using 9% zinc oxide and 7.5% octinoxate. Sometimes in particular with chemical UV filters irritation is an important consideration, and I bring this up because while researching this product I did find a small amount of study Show more
