answers, not verdicts

Ask.

Is retinol safe while I'm pregnant?
In Australia retinol above 1% is prescription-only, and topical retinoids are advised against in pregnancy as a precaution. Below that, systemic absorption looks very low, but this is a case to take to your doctor, not an app.

The day's scare, answered from the graph. Screenshot-ready.

"Chemical sunscreens are toxic."
Overblown

The most protective product on an Australian shelf. Daily use cut invasive melanoma by 73%. Skipping it is the actual risk.

Nambour RCT, HR 0.27 · AS/NZS 2604 · TGA

"Phenoxyethanol is a neurotoxin."
Dose-blind panic

Capped at 1% in the EU, and that trace is exactly what lets a formula skip harsher preservatives. The scare is about swallowing it.

EU Annex V, ≤ 1%

"Every chemical filter is fine."
Needs nuance

The backlash overshoots too. Oxybenzone is restricted above 2.2% on the body. Dose still decides, both ways.

Matched on the active that matters, not on marketing. Same working dose of niacinamide, less per milligram.

What is in the box

Full-size worth~ $186
Honest worth, for you~ $90

That is what these volumes cost at full-size RRP, not resale cash. Minis rarely resell, so read it as what you are holding.

Four of the six score clear for you. Two carry a fragrance you react to, and one duplicates what you own, so the honest figure lands nearer $90.

How we value a box

show the working

Full-size RRP ÷ full-size volume × the sample's volume, always shown with a per-mL figure, the same way we cost an active. Worth, never a hyped-up value sticker.

Full-size RRP$78 / 50 mL
In the box8 mL deluxe

Per mL$1.56 / mL
Not resale cash. Deluxe minis rarely resell at full-size rates.
Value is not fit. Every mini still wears its own mark.
We do not count what you already own or react to.
