The 5% off voucher at the top of this page is the lead offer for OLIVE YOUNG. It gives a straight 5% reduction across a qualifying purchase when you apply the code at checkout and sign in to your account, so it is best for full price online carts where you want a simple sitewide saving.
Big full price carts, multiple items: Use the 5% off voucher at the top of this page. When most of what you are buying is full price, a flat 5% off every eligible line item will usually save more than a single item sale. The voucher requires account sign in and must be entered at checkout.
If you are buying a single heavily discounted sale item: Take the sale price. Selected sale items are reduced by up to 72% and some individual products have 50% or 20% reductions with no code needed. For example, the Beauty Of Joseon Daily Tinted Fluid is shown at 50% off and LANEIGE Lip Sleeping Mask at 20% off; those reductions apply directly at the product price and do not require a code.
Mixed carts with some sale and some full price lines: Compare line by line. Apply the 5% voucher to the basket if the combined 5% saving on full price items outweighs the dedicated sale reductions on the sale items. If a sale item already has a larger percentage off, that item will usually be cheaper at its sale price than after applying a 5% voucher to the whole order.
Shopping in store: Several 5% codes on the page are labelled in store only and also require sign in. If you plan to pay in a physical OLIVE YOUNG location, use one of the in store 5% offers that lists that condition rather than the online selected products code.
Buying online selected range only: There is a 5% off selected products code that applies on the website. If your cart contains only items from that selected online range, that code gives the same percentage saving as the sitewide voucher but may be confined to specific SKUs.
Newsletter signup for first time customers or very low spend: Signing up to the newsletter is the only signup style option listed. It may be useful if you prefer email offers, but it is not a headline discount and is appropriate only if you want promotional emails rather than an immediate higher percentage saving.
When choosing, total the cart at full price, subtract percentages or fixed sale reductions in the order they apply and take whichever option leaves the lower final amount. Do not assume sale prices can be combined with a voucher unless the offer terms say so.
