IS RETINOL EYE CREAM GOING TO BE TOO STRONG AROUND THE DELICATE EYE AREA?Updated 6 months ago

HPR is exclusively used in Retinol Eye Cream. It is an Ester of Retinoic Acid which is claimed to work similarly but without the irritation. Manufacturer patch testing results in significantly lower irritation when compared to the same concentration of Retinol.Because HPR is an ester of Retinoic Acid – the active form of Retinol, instead of an ester of Retinol, it doesn’t have to go through the same conversion process to be used directly by skin. So, in theory, a lower amount of HPR can elicit the same results as higher concentrations of Retinol.
