Finally found the one

Love this retinal. Using twice a week followed by a barrier repair cream has my skin looking rejuvenated and has stopped hormonal acne from flaring up completely. Had tried a few other brand retinols previously but they always left my skin feeling tired and tender when I’d try to build to more frequent use. This feels gentle yet is super effective.

Best Vitamin C ever

Adds a noticeable glow to my skin and doesn’t have any kind of off-putting scent like some other brands. The consistency of the serum is very liquid so be mindful when applying, and can have some issues with the pump mechanism/consistency of what is really 1 or 2 pumps worth. If this could be fixed with compromising the formula it would really be perfect, but the results are what counts - firmer, smoother, brighter skin!

This works

I love this - not too strong - doesn’t irritate my skin and I have noticed a real difference in 2 weeks of use. A little goes a long way.

Love this
