This issue's correspondence
You graded hydrolysed collagen 'Partly true' on the basis of skin elasticity endpoints. But two of the meta-analysis trials measured wrinkle depth, not elasticity. The wrinkle data is weaker. I think your grade is too generous unless you separate those endpoints in the next revision.
Your supplement piece recommends 240mg twice daily. My derm here suggested 480mg morning only. Is the split-dose preference based on PK, on convenience, or on the trials? I tolerate Heliocare fine but would rather take it once.
I love the diagnostic but it routed me to the wrong concern guide. I described pigment + reactive skin, and got Melasma + UVMune. But I have post-inflammatory hyperpigmentation from acne, not melasma. The two need different treatment ladders. Worth distinguishing in the routing logic?
I bought the Currentbody mask three months ago. Your 'Partly true' verdict matches what I'm seeing in the mirror — modest, real, slow. The thing I appreciated most was that you didn't tell me to return it.
