The 20% off code at the top of this page is Lanshin's headline offer and gives you the biggest discount across the entire skincare range. This code beats the other available coupon codes and will save you more on every basket size, so it is worth using unless you are shopping selected sale items at a higher percentage discount.
On any order of skincare products, use the featured 20% off code. On a $100 order, for example, you save $20 and pay $80. The three other percentage codes give either 15% or 10% off, which are smaller savings at every price point.
If you are buying from the current sale, compare the 20% code against the sale discount on the items in your basket. The sale gives up to 25% off selected skincare products through 31 October 2026, and the multi correctional facial serum is included. If your selected items are marked at 25% off, the sale saves more than the code; if they are at a lower percentage, the 20% code is the better choice. Use whichever leaves you the lower total at checkout. One code restricts you from stacking other offers, so check the terms if you are applying a code to a sale item.
If you are a new customer, the newsletter signup may give you access to special offers and promotions, but no specific discount is stated at signup, so the 20% code is the clearer choice right now.
In the 12 months to October 2026, Lanshin codes have ranged from 10% to 20% off, with 15% off being typical. Our team tested 3 Lanshin codes at checkout in that window, and all of them worked as shown. The biggest sale in that time was up to 40% off in November 2025, so if you are patient there may be larger discounts ahead, but the 20% code is the strongest offer available right now.
When you have worked out which discount applies to your order, choose the code or sale that gives the lower final total. Read the terms at checkout to confirm the offer applies to every item you are buying.
