Ingredients explained

Also-called: Zemea | What-it-does: solvent, moisturizer/humectant

Propanediol is a natural alternative for the often used and often bad-mouthed propylene glycol. It's produced sustainably from corn sugar and it's Ecocert approved. 

It's quite a multi-tasker: can be used to improve skin moisturization, as a solvent, to boost preservative efficacy or to influence the sensory properties of the end formula. 

Also-called: Form of Vitamin C, 3-O-Ethyl Ascorbate, EAC | What-it-does: antioxidant, skin brightening

A very stable and promising form of the skincare superstar, Vitamin C. If you do not know why Vitamin C is such a big deal in skin care, you can catch up here. In short, Vitamin C has three proven magic abilities: antioxidant, collagen booster, and skin brightener. The problem, though, is that it's very unstable, turns brown and becomes ineffective in no time (after a few month) and the cosmetics industry is trying to come up with smart derivatives that are stable and have the magic properties of pure Vitamin C. 

Ethyl Ascorbic Acid or EAC for short is an "etherified derivative of ascorbic acid" that consists of vitamin C and an ethyl group bound to the third carbon position. This makes Vitamin C very stable and soluble in both water and oil.

However, for a Vitamin C derivative to work it's not enough just to be stable, they also have to be absorbed into the skin and be converted there to pure Vitamin C. We have good news regarding the absorption: on top of manufacturer claims, there is some data (animal study) demonstrating in can get into the skin, and it seems to be better at it than Ascorbyl Glucoside, another vitamin C derivative.

Regarding conversion, we can cite only a manufacturers claim saying that EAC is metabolized in the skin into pure ascorbic acid (and the ascorbic acid content of EAC is very high - 86,4% - compared to the usual 50-60% Vitamin C content of other derivatives). 

As for the three magic abilities of Vitamin C, we again mostly have only the manufacturer's claims, but at least those are very promising. EAC seems to have both an antioxidant and anti-inflammatory effect, and it's claimed to be able to boost the skin's collagen production. The strong point of EAC though is skin brightening. On top of manufacturer claims, there is also clinical in-vivo (tested on real people) data showing that 2% EAC can improve skin tone and whiten the skin. 

Overall, Ethyl Ascorbic Acid is a very promising but not a fully proven Vitamin C derivative. It's worth a try, especially if you are after Vitamin C's skin-brightening effects. 

Also-called: Radianskin | What-it-does: skin brightening

skin-brightening, spot fading active ingredient that goes by the trade name Radianskin. The in-vitro (made in the lab) test results of the manufacturer show that it can prevent melanin formation more effectively than other well-known skin-lightening agents, like ascorbyl glucoside, kojic acid, or arbutin and it has equivalent efficacy to skin-lightening gold-standard ingredient hydroquinone but without cytotoxicity.

There is also a L'Oreal sponsored research showing that the combination of hydroxyphenoxy propionic acid, ellagic acid, yeast extract, and salicylic acid produced comparable skin-lightening results as the standard prescription combination of 4% hydroquinone cream and 0.025% tretinoin cream after 12 weeks. 

Also-called: SymWhite | What-it-does: antioxidant, skin brightening

A skin-lightening and antioxidant active ingredient derived from a molecule that exists naturally in Pine tree. According to the clinical results of the manufacturer, 0.5% of phenylethyl resorcinol is more effective than 1% of well-known skin-lightener kojic acid. 

Though the results from the manufacturer sound quite promising, a skin-lightening study from 2013 involving phenylethyl resorcinol shows quite moderate results. In the 80 participants, 12-week study, phenylethyl resorcinol was combined with three other actives (disodium glycerophosphate, L-leucine, and undecylenoyl phenylalanine) and only 57% of the participants showed at least a moderate response and 17% did not improve at all.
