Treatment - as in my full treatment dose of 15mg or whatever I deem appropriate?The best long term outcomes for acne, besides the 220mg/kg cumulative dose, were achieved when treatment continued for 50 days after full clearance.
So pulsing means better skin elasticity, and constant low dose means better skin cell renewal?As to collagen, based on the study I linked, the genes that renew collagen behave like switches. They need a certain intracellular retinoic acid concentration to trigger collagen synthesis. Pulses above that threshold transiently induce collagen synthesis and suppress MMP-9 (collagen degrading enzyme) more effectively than constant sub-threshold exposure.
The daily low dose is more effective at skin improvement the upper layers. But there is still a positive impact on collagen, it's just slower.
I wonder if I should switch to 20mg ed to keep that switch triggered daily?
If so, if aiming for 5mg ed, couldn't/shouldn't I go for 2x20mg e3/4d??
There still seems to be a certain benefit form using Tretinoin cream additionally, or is that not the case?
Thanks!
