I'm not using the microsphere one. Is there any particular reason why the microsphere one may be superior?Make sure to use the tretinoin that specifically says "Microsphere". I get it from alldaychemist but unfortunately they've been out of the .1% version for over a year now so been using the .04% tretinoin microsphere.
If anyone knows where there is .1% available online would like to know. Might have to go to the derm for a script as I'd like to up my percentage.
I researched this a lot when I first started using it a while ago (10-15 years ago). Can’t recall all the details but from what I do recall the microsphere version is more of a slow release & better for anti-aging purposes. Whereas the gel is typically better suited for acne.I'm not using the microsphere one. Is there any particular reason why the microsphere one may be superior?
