The 20% off voucher at the top of this page is the lead offer for Oh Beauty, and it is best for most full price orders across the site because it takes 20% off your cart total. The voucher must be entered at checkout and cannot be used with any other offer, so it works best when nothing else in your cart is already on a sale that gives a larger reduction.
Small purchases under $100. If your cart is about $60 and it contains sunscreens, the automatic 25% off daily SPF essentials will usually save more on those items because it applies at checkout without a code. For example, on a $60 sunscreen order the 25% sale reduces the price to $45, a $15 saving; the 20% voucher would reduce $60 to $48, a $12 saving, so use the sunscreen sale instead when your basket is mostly those items. Applies: 25% off daily SPF essentials.
Orders around $100 to $299. If you are not a new customer and your selection is full price, the 20% voucher at the top is generally better than the sitewide 15% offers. For example, on a $120 full price order the 20% voucher takes the price to $96, a $24 saving, while a 15% offer would take it to $102, a $18 saving, so use the 20% code for full price items. If your cart is mostly sunscreens or selected sale brands that already have 20 to 40% off, compare the automatic sale price for those items because sale discounts apply at checkout without a code. Applies: 20% off voucher; compare with listed sales such as 20% off sunscreens, up to 30% off selected brands, or up to 43% off selected items.
First time buyer or new member. If you are eligible for the 15% off first purchase code, it only applies to new customers and cannot be combined with the 20% voucher. For a small first order the 20% voucher still gives a bigger saving than 15% when both apply to the same items, so use the 20% voucher if you can. If a sale gives more than 20% on the exact items you want, take the sale instead. Applies: 15% off first purchase for new customers, or the 20% voucher for general use.
High spend carts and free gift thresholds. For orders over $299 you qualify for two free gifts; over $499 you qualify for three free gifts. On a $600 full price order the 20% voucher reduces the total to $480, a $120 saving, and also meets the $499 free gift threshold, so the 20% voucher is a strong choice for big full price carts. If your high spend cart is concentrated in items shown in the up to 43% sale or the 40% archive sale, those sale prices may beat the voucher for those specific products.
Our records show 29 percentage codes in the 12 months to October 2026, the biggest was 30% off and the typical code was 20% off. Our team carried out 22 checkout tests across 22 offers in the 12 months to October 2026.
Choose the single option that leaves the lower total. If a sale price on the exact items you want gives a larger percentage off than 20% then take that sale because the 20% voucher cannot be combined with other offers. Otherwise use the 20% voucher at the top of this page for the biggest straightforward saving on full price baskets.
