Our affiliate stance

Drop earns a small commission if you buy a product through one of our links. We disclose this every time — inline on the product card, in the footer of this site, and on this page.

We don’t pay for reviews, and we don’t route unhappy users away from leaving one.

Fit ranks the order. Evidence backs the verdict. The two jobs are kept separate on purpose:

1. Fit — compatibility with the routine you already have — decides the order recommendations appear in.
2. Evidence — the peer-reviewed citations behind the active — decides what we say about a product, and never changes because a link exists.

We never rank by which affiliate program pays us more. Three rules keep this honest:

• Maximum three cards per recommendation surface. We will not pad the list to surface more affiliate links.
• Ranking ignores commission rate. The sort order is deterministic and reviewable — commission is not an input.
• If your routine does not need anything, we say so. The most common Drop answer is “your routine is doing the job.” A “no recommendation” result earns us zero — and that is fine.

We surface the disclosure in three places so you never have to dig for it:

• Inline on every product card— a short line on the card itself: “Drop earns a small commission if you buy through these links. Commission never changes what we recommend or the order you see.”
• In the footer of this website, on every page.
• On this page, with the full stance.

Affiliate links exist only on buy-intent surfaces: in the app, and on shared wishlist and empties pages on this site — always disclosed next to the links. Reading surfaces — shared routines and shelves, profiles, articles, the ingredient encyclopedia, the routine-rating and pairing-check tools — carry no affiliate links, ever. Links are never ordered by commission, recommendations are ranked by fit with your routine, and brands cannot pay for placement.

Drop participates in the following affiliate programs. Some are live; others are applications submitted ahead of our public launch and may not be active when you read this:

• Amazon Associates.
• Skimlinks (which routes traffic to a broad catalogue of retailers).
• Select brand-direct programs: Paula’s Choice, Deciem (The Ordinary, NIOD), and CeraVe.

When we add a new program, we update this page and surface the new participant in the inline card disclosure. We do not run sponsored placements, paid editorial, or advertorial content. We do not sell user data. (See our privacy stance for the full list of things we do not do.)

Drop is free to use. You never need to buy anything we recommend. The most useful answer Drop can give you is often that the routine you already have is doing the job — and we say so. If a product on your shelf works, keep it. If a drugstore option matches the active ingredient at the same concentration, we surface it alongside the premium one.

If you spot a recommendation that looks like it favours commission over fit, please tell us. The inline disclosure and the ranking rules above are load-bearing for us — getting them wrong is the failure mode we care about most.
