Hydroxyphenoxy Propionic Acid

Also-called-like-this: 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.
