If I cleanse my skin and apply a few drops of oil on moist skin, then wait 30 min before applying Retin A to buffer it to lessen irritation, will this
a) slow penetration?
b) reduce amount of tretinoin reaching dermis?

Would this be somewhat equal to Retin A micro?

Also, I should have bought the 0.025% instead of 0.05% - if I use half as much will this be like using a weaker percentage? Should I dilute 1/2 peasize Retin A w/1/2 peasize lotion?
