Hi, I just checked out Iope and I am wondering why youโre going back to retinol instead of continuing with retinaldehyde? Is it the price issue? Cause Medik8 is a bit pricey:) Also 0,1% for retinol is very low even if they promote it to be very advanced technology. Iโve used the Medik8โs retinol 0,3% for the past year with no side effects and Iโm now leveling up to 0,05% retinal from Geek&Gorgeous.
