smoking a ciggy while reading this goes hard nglDon't be condescending bro, i'm sure microneedling can be effective in ways, but i'm almost 100% sure that microneedling won't increase the effectiveness of tretinoin. By microneedling you literally make the tretinoin BYPASS the areas it's supposed to work in. You won't increase either the speed or effectiveness by pushing it deeper into the skin. It's lipophilic so it doesn't need help bypassing the skin barrier.
