We generally recommend using granactive retinoid 2% or granactive retinoid 5% instead of this formula
While Retinol has been studied extensively, it is irritating to the skin and technologies exist that mimic the visible effects of Retinol without causing skin irritation
There is a one problem in the application, if we choose two different articals or two different Color’s software never allows us. So please check the application and correct it.
Thanks
