Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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. Stay hydrated!
Learn more about WaterCetearyl alcohol is a mixture of two fatty alcohols: cetyl alcohol and stearyl alcohol. It is mainly used as an emulsifier. Emulsifiers help prevent the separation of oils and products. Due to its composition, it can also be used to thicken a product or help create foam.
Cetearyl alcohol is an emollient. Emollients help soothe and hydrate the skin by trapping moisture.
Studies show Cetearyl alcohol is non-toxic and non-irritating. The FDA allows products labeled "alcohol-free" to have fatty alcohols.
This ingredient is usually derived from plant oils such as palm, vegetable, or coconut oils. There is debate on whether this ingredient will cause acne.
Due to the fatty acid base, this ingredient may not be Malassezia folliculitis safe.

Surfactants help reduce surface tension between ingredients with different states, such as liquids and solids. Emulsifiers help prevent oils and waters from separating.
Polysorbate 60 is sorbitol-based and created from the ethoxylation of sorbitan. Ethoxylation is a chemical reaction used to add ethylene oxide. Sorbitan is a the dehydrated version of sorbitol, a sugar found in fruits.
In this case, the 60 comes from reacting 60 units of ethylene oxide with sorbitan.
Polysorbates are commonly used in medicine and foods.

Lesvds me glowing and hydrated
I use this every morning and it blends in perfectly with no White cast at the end and leaves my skin feeling soft, hydrated, dewy, and glowy!
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

I enjoyed this sunscreen. My skin took to it very well and it is very moisturizing. I just wish it had a higher SPF, If you have dry or combo skin. I would give this a try.
I bought it as a moisturizing and priming sunscreen for colder months, but even in winter it would make my skin so sticky and oily after a few hours. Moreover, during application the texture feels a little bit grainy even when shaken well before use.
If you use a toner and a serum underneath, get ready for pilling when applying makeup. I tried it with a lot of different serums and can tell that Show more
