This has been going for long enough that there's been several metastudies debunking it. Was hyped in the news around 2017.
Fish skin or silver sulfadiazine had similar effects and to me are both approximating placebo from the studies I read. The fish does nothing for pain and no difference in the scarring time vs the silver ointments.
fish skin (rich in collagen) sounds like a version of collagen patch. And for collagen patch for example https://pmc.ncbi.nlm.nih.gov/articles/PMC3081477/ where despite the "Conclusion" the "Results" show that it helps (and one can also expect that collagen patching is starting point to engineering artificial skin) :
Results:
With two weeks of treatment, 60% of the ‘collagen group’ wounds and only 42% of the ‘conventional group’ wounds were sterile (P=0.03). Healthy granulation tissue appeared earlier over collagen-dressed wounds than over conventionally treated wounds (P=0.03). After eight weeks, 52 (87%) of ‘collagen group’ wounds and 48 (80%) of ‘conventional group’ wounds were >75% healed (P=0.21). Eight patients in the ‘collagen group’ and 12 in the ‘conventional group’ needed partial split-skin grafting (P=0.04). Collagen-treated patients enjoyed early and more subjective mobility.
Conclusion:
No significant better results in terms of completeness of healing of burn and chronic wounds between collagen dressing and conventional dressing were found. Collagen dressing, however, may avoid the need of skin grafting, and provides additional advantage of patients’ compliance and comfort.
You made me go re-search for those meta studies and I can only find a brazilian one which disputes the claims but I do find a few showing benefits. I'm back to not knowing what to believe in isolation, but with results also for plasters that you shared I'm more leaning towards you being right. Thanks for sharing.
Totally anecdotal but I had a bad burn on my foot and I thought I could manage it with otc stuff. It kept getting worse so I went to have it checked out and was prescribed the silver cream.
From one day to the next it started showing positive effects and a week and a half later I was fine. I was kicking myself for waiting so long.
