New Customers Get 15% Off Their First Order

Yes, one: 15% off, limited to new customers. It runs to 31 December 2026. It comes from Dermstore's own advertiser feed rather than a shopper submission, so those terms are the retailer's own wording, not our reading of it.

The code on this page carries one restriction — new customers — and that is the first thing to rule out, because the checkout rejects it the same way whatever else is in the cart. After that it is the exclusion list. Dermstore is a retailer rather than a brand, and clinical and physician-dispensed lines are routinely carved out of a promotion — so a code can take its full value off one cart and nothing at all off another. A code that looks dead has usually worked exactly as intended on a brand it was never valid for.

The 1500 items in the catalogue this page checks against run from $5 to $1700, with the middle of them at $54. On that item the code is worth $8.10, taking it to $45.90. Paste what you are actually buying and the page does the same arithmetic on that price.

$50 on US orders, and the threshold is assessed on what you pay after the code rather than on the list price. 694 of the 1500 items in the catalogue behind this page (46%) sit under it on their own, and the code drops another 124 below it. That is why this page shows the gap to free shipping once you have picked an item: on a single-item order the two can pull against each other.

Rarely. Sitewide codes here normally exclude anything already reduced, so on a given product the sale price and the code are an either/or rather than a stack. Paste the item and the page prices both, instead of assuming the percentage wins.

The Anniversary Sale in spring and Friends & Family are the headline events, with Black Friday and Cyber Monday the most dependable. Black Friday also tends to carry the shortest exclusion list, which can make a smaller headline percentage worth more on a cart of clinical brands.
