A positive IgE or skin-prick test does not automatically mean clinical allergy. It may show sensitisation only. The useful question is not “Is the test positive?” but “Does exposure reproducibly cause symptoms?” More: https://t.co/FPxmnWoV1w
PA++++ does not mean every sunscreen gives the same UVA protection. A product just above UVA-PF 16 and one near 40 can carry the same label. For pigmentation, repeated small UVA exposures matter more than a simple “safe time” calculation. https://t.co/2Wgx8fgK71
PDO scalp threading may improve hair growth. But the key question is still unanswered: does the thread itself add anything beyond the needle injury?
Before asking which thread is best, perhaps prove that the thread is needed at all.https://t.co/2PDm7gHKDr
Inflammoscopy now has strawberries, starbursts, clouds, rosettes, polygons, leaves and starry skies.
But Does dermoscopy actually improve diagnosis beyond competent clinical examination?

ChatGPT confidently called muscle a fibrosed nerve, cited literature, suggested Fite stain/PCR—and then changed its interpretation when the premise changed. The problem is not just hallucination. It is plausible, specialist-sounding error. https://t.co/St4rshUmn8
A treatment can be biologically plausible, commercially available and still not be ready for routine use. Exosomes, “salmon DNA,” IV drips and thread lifts deserve the same question: what meaningful, lasting benefit has actually been proven?https://t.co/HSDugZKHRz

Grey hair can occasionally repigment. That does not prove an anti-grey serum can reverse age-related greying. Small trials, laboratory markers and company-led studies are not the same as visible, durable results. Evidence matters. https://t.co/kQQjEYQbWE
