I am considering the use of Renova, probably about 3 times/week and am wondering if it would be a problem to apply Retinol in Squalane after? So the routine would be diluted CP Serum, followed by Renova, then Retinol in Squalane. Would the squalane draw too much of the tretinoin into the skin? And would the retinol combined with it be too much Vitamin A derivatives at once? Thanks for the help. By the way, I would apply these under the eyes as well as the rest of the face.

The squalane will push more Renova in the skin, so be careful of overuse at first.

I wouldn't put renova in the eye area.
