[misc] what do you think of VitC derivatives?

Beauty Tips For Body Care
I am well aware that there’s very little scientific research to support the efficacy of topical vitamin c in skincare except with use of a very well formulated LAA. That being said, I feel like “lack of scientific research” is true of most OTC skincare so I just want to hear anecdotal experiences and opinions.In your experience, is only LAA worth it? Or, have you seen results with derivatives just less dramatic or over a longer period of time than it would take LAA? Or, what I’m super interested in, is have you had different experiences depending on the derivative? How have your experiences with SAP vs MAP vs THD vs the others I can’t remember off the top of my head compared?
