It is essential for my sunscreen to have antioxidants and plenty of them. Sun protection actives can break down and cause free radical damage, so much as we need their UV protection, we also need to counterbalance with ingredients that help protect our cells – hence the antioxidants that are packed into Skinfinite Platinum 30spf (1.7 fl.oz/$32.50).

Skinfinite is already a big favorite with the Truth In Aging community for its effective formulas and no-nonsense approach. Skinfinite Platinum 30spf is worthy of being embraced just as enthusiastically. This is a good mineral sunscreen, an easy to apply gel that works well over serums and under makeup, packed with good things and – drum roll – no chalkiness whatsoever.

Research suggests that sunscreen with antioxidants can reinforce the role of the sun protection active (zinc oxide in the case of Skinfinite 30spf). A study in Journal of the American Academy of Dermatology (AAD) backs antioxidants as a way of boosting our natural immunity to sun damage. So you’ll be pleased to know that Skinfinite 30spf comes with a bevy of fine antioxidants.

There’s ergothioneine, a natural antioxidant amino acid found in mushrooms. There is some research that claims that ergothioneine is a much better antioxidant than idebenone. Porphyra umbilicalis is a kind of edible seaweed, known as red seaweed. It has good antioixidant properties, according to research.

Much more interestingly a component of red seaweed, called MAAs, was encapsulated in liposomes and used as a sunscreen. It not only performed as well as a synthetic sunscreen, it did not – unlike most conventional sunscreens – produce “reactive intermediaries”. These MAAs seem to be quite the thing: they render UV into “harmless thermal energy” and they also scavenge harmful free radicals (source). A definite enhancement to any sunscreen.

I also like that there is macadamia, rich in fatty acids, barley (a Dr Perricone anointed superfood that has lots of niacin and a turbo charged version of vitamin E), and bark from a kind of cork tree that is abundant in quercetin, a potent antioxidant.

What would have been a formulating triumph is a little marred by the inclusion of sodium hydroxide, an irritant, behenyl alcohol, and phenoxyethanol. A word about the packaging of Skinfinite Platinum 30spf. The pot is in fact a kind of airless pump with a flat surface that, when depressed, dispenses the gel inside. The product must, therefore, be smeared off the flat surface with a finger and then applied. I personally don’t have an issue with this, but it makes this sunscreen one for the bathroom rather than beach.
