Skintific Perfect Stay Velvet Matte Cushion Versus Revlon Colorstay Makeup For Combination/Oily Skin SPF 15

The safety profile of this ingredient is reassuring; the US CIR Expert Panel concluded D5 is safe as used in cosmetics and Health Canada concluded that D5 is not harmful to human health or the environment as currently used in cosmetics

There's a study that people mention about D5 in a rat study showing tumors. This study is related to long-term inhalation of high D5 levels.

Regulatory bodies have judged this study to be not applicable in topical skincare since skin absorption of D5 is very low and we're not really inhaling huge amounts of D5.

The only restriction for this ingredient is environmental. The European Chemicals Agency (ECHA) restricted D5 in wash-off cosmetics at or above 0.1% due to their persistence in water.

In cosmetics, Magnesium Sulfate is used to thicken a product or help dilute other solids. It is a non-reactive and non-irritating ingredient.

One study shows magnesium deficiency may lead to inflammation of the skin. Applying magnesium topically may help reduce inflammation.

You can find this ingredient in sea water or mineral deposits.

This ingredient may not be fungal acne safe because research has shown that the Malassezia species can grow in the presence of fatty acid esters with chain lengths above C12 (and this one is C18).

While it does have a comedogenic rating of 4, the comedogenic rating scale was developed from rabbit ear models which has limited clinical relevance to human skin. Studies also show that comedogenic ingredients cannot predict how the overall formula will behave on human skin.

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.

This ingredient may not be fungal acne safe because behenic acid falls into the chain-length range that Malassezia yeasts can feed on.

This ingredient is typically used at low levels (up to 2.5% in eyeshadow and 1% in lipstick).

According to a manufacturer, it can blend seamlessly with silicone oils, such as Cyclopentasiloxane.

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!
