Hello skin care friends. Can someone please tell me how to mix the COQ10 powder and Alpha-lipoic Acid, can i mix it in a cream like cerave or should i make a serum and how much do i use in tbsp or oz, and can i put it on after my DIY C serum in the morning. I use .5% retinA every other night or is it ok to use at night with retin A. thanks for all and any advice.
