I'm not yet convinced that the benefits outweigh the potential drawbacks.There are a couple studies out there that have evaluated the effects of low-dose isotretinoin (Accutane) on collagen production. On average, study participants who took isotretinoin (60 mg/week) for 8 weeks (I think) exhibited a 50-60% increase in collagen levels. For someone who's 30+, that's hugely significant, and if the study results can be extrapolated to those of us in the general population, then it means that low-dose isotretinoin could be the most effective treatment available for boosting collagen levels.
@benignice If I recall correctly, I think you said you weren't really convinced by these studies (even though they weren't funded by the manufacturer or whatever)... ?
Also something to bare in mind is that a lot of these studies (in order to see much difference) are conducted on older people who didn't have the benefit of the knowledge that we now have re sun exposure, topical retinoid use, etc (even just going back to the 80s and 90s) and therefore are now likely dealing with worse skin (as a population) than we will.
