Ingredients Explained

These ingredients are found in both products.

What it does: Skin Conditioning, Solvent
Community Rating: Loved

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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Alcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol and other additives. It has a low molecular weight and will evaporate quickly. This helps other ingredients become better absorbed and dry once applied.

Alcohol Denat. is volatile and may cause irritation. It helps draw out natural oils in skin and dry out your skin.

One study from 2005 found adding emollients to propanol-based sanitizer decreased irritation.

Alcohol is antibacterial by nature. This can help preserve products and increase their shelf life.

Other types of astringent alcohols include:

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.

Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UVA absorber. It is formulated for high UVA protection (320-400 nm) and photostability.

DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%.

UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy.

UV rays are a form of electromagnetic radiation from the sun. Other sources include tanning beds and welding torches. Radiation is the emission of energy. UV Rays are divided into 3 groups. UVA (320-400 nm) contains the least amount of energy. They are linked to long term skin damage such as wrinkles and hyperpigmentation. UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA in skin cells. UVB causes sunburns and are thought to be linked to skin cancer. UVC (200-280 nm) contains the highest amount of energy. Our ozone blocks UVC. UVC can also originate from welding torches, mercury lamps, and sanitizing bulbs.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

EDTA is the shortened name for ethylenediamine tetraacetic acid. It is a chelating agent and used to stabilize products.

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and 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.

I'll start by saying that yes, this feels like practically nothing on the skin, and it's very similar to a primer as far as texture goes.

BUT...

I'll start by saying that yes, this feels like practically nothing on the skin, and it's very similar to a primer as far as texture goes.

BUT once applied, I didn't feel the same level of protection as with the European SPFs I used to use. I even applied half of each on my face to compare:

With the European one I experienced a cooling effect and didn't feel any heat touching my skin, it was like being hugged by icecream (a weird comparison, but it's the closest I can think of). Meanwhile, with this one, I didn't feel anything? I felt the heat touching my skin as much as on my non-protected areas, and there was no cooling effect whatsoever.

Is it cosmetically elegant? Yes. Is it cheaper than any European SPF? Yes. But I prefer not to play around with sun protection knowing the damage it can cause, and I don't feel 100% safe using this one.
