A Sample

What the briefing actually looks like.

Below: a real opening from a recent issue. No paywall, no upsell.

The Skin-ny
Issue No. 46 · 5 June 2026
The Open

The £280 serum that didn't survive its own claims.

On Tuesday, a luxury house we won't name yet recalled a flagship serum in eleven markets after a stability audit showed its active was, by month four, doing almost nothing.

The recall is small in volume and large in implication: the formula was launched with a clinical study that ran for twelve weeks. Most users keep a serum for six months.

We bought three batches at retail. All three failed by week eighteen. The full breakdown is on page four.

Finally a skincare read that tells me when not to buy something. My bathroom shelf is smaller and my wallet is happier.

I work in beauty PR. The Skin-ny is the only outlet I trust to actually read the studies. Painful, but fair.

The recall section alone is worth it. I've returned two products this year because of a Thursday email.

Who It's For

For the curious spender who has read the back of a Sisley box and thought, "really?"

  • You buy from La Mer, Augustinus Bader, Dr Barbara Sturm, and want a second opinion before the next reorder.
  • You've returned at least one £200 cream because it didn't do what the label said.
  • You think "reef-safe" without a regulator behind it is marketing, not science.
  • You'd rather one honest weekly read than five hopeful Instagram carousels.
