Can these products be used together?

Question: Hello, I use retina/tretinoin 3x per week, and have combination-oily skin. I would like to start cleansing with either iS Clinical Cleansing Complex or SkinCeuticals LHA Cleanser Gel (preferrably iS Clinical because i have light rosacea) but want to make sure either of those would be ok to use right before applying retina? I read in one of DermStore's blogs that retinol should not be mixed with glycolic acid or vitamin c. iS Clinical has Vitamin C and SkinCeuticals LHA has glycolic acid. I'm 33 years old and feel like it is time to make some changes in my skincare routine but want to make sure i do all of my research first. Any guidance would be greatly appreciated! :)

Thank you for reaching out to us. In answer to your questions you are right on both products. I would recommend that the nights that you are using your retinol I would use SkinCeuticals Gentle Cleanser. I think this cleanser would benefit your skin better . iS Clinicals Cleansing Complex is a great cleanser to use interchangeably. I hope this helps, have a nice day! Cyndee, Dermstore Esthetician
