Weekly journalism on sunscreen science, ingredient regulation, and the global sun-care beat — written for the curious, not the algorithm.
Tallow balms have gone from cottage-industry curiosity to crowded shelf. Here is a criteria-based way to read one — ingredient list, sourcing claims, scent, freshness and price — without relying on marketing.
What zinc oxide is, how it really protects skin (absorption, not a mirror), where regulators stand in Australia and abroad, and which of its reputations hold up.
Four ingredients that all promise to seal moisture into skin, compared on composition, feel, breakout risk, allergy and how much evidence actually sits behind each.
Grass-fed cattle really do produce a different fat — more omega-3s, more CLA, more vitamin E. What nobody has shown is whether your skin can tell.
The claims made for beef tallow on skin are enormous. The published research is small, mostly indirect, and genuinely interesting where it exists. Here's the honest ledger.
Beef tallow has gone from butcher's off-cut to bathroom shelf staple. Here's what tallow skincare actually is, how the fat is rendered, and where it fits — honestly — in a routine.
The chalky film is a light-scattering problem, not a quality problem. Here is the physics behind zinc sunscreen white cast, what formulators do about it, and what actually helps at the bathroom mirror.
"Non-nano" has become a shorthand for "safer" on sunscreen labels. Here is what particle size actually means, what regulators have found, and the one restriction they really do impose.
Yes, it expires — and the Australian summer is harder on a bottle than the date stamp suggests. How to store it, spot a dud, and when to bin it.
Both filter families protect you, and both are regulated as medicines in Australia. Here's what actually separates them — and what doesn't.
Wellness influencers say sunscreen is toxic, blocks vitamin D and even causes cancer. The evidence says otherwise — emphatically. Here's what the research actually shows, and why the claims keep spreading anyway.
A year after CHOICE found 16 of 20 sunscreens failed their advertised SPF, the recalls have widened and the TGA is weighing the biggest overhaul of sunscreen regulation in decades. Here's the full timeline — and what it means when you reach for the bottle.
Rendered beef fat has gone from butcher's by-product to one of the fastest-growing ingredients in skincare. The market is real, the mechanism is plausible — and the clinical evidence is still remarkably thin.
UCLA researchers have reshaped zinc oxide into tiny "tetrapods" that keep their SPF but lose much of the chalky finish — a lab-stage advance that could matter most for darker skin tones.
