It's common knowledge - every woman needs to own at least one red lipstick. And at least one YSL lipstick. How about killing two birds with one stone? YSL's Rouge Pur Couture range is densely pigmented with a smooth and moisturising finish on the lips. Le Rouge #1 is the epitome of perfect red lipsticks; we all know how reds with orange undertones are better suited to warm skintones, and reds with blue undertones suit cool skintones. Le Rouge combines the perfect balance of both for a universally flattering shade in a beautiful formula.

Better still, you could get yours at a really unique price, thanks to the way BuyaPowa enables everyday shoppers to come together and access the amazing bulk-buy discounts only large retailers usually enjoy. And as for the shipping- we'll whisk it to you for just £1.95. 

YSL have truly smashed it out of the park with the Rouge Pur Couture formula. Free from all those chemical nasties incuding parabens, sulfates, petrochemicals and phthalates, it still packs a seriously pigmented punch whilst caring for your lips and lasting hours on end. If you're not one for touching up your lipstick part way through the day, that's not a problem - when this colour does start to wear off, it fades into a beautiful red stain that looks just a gorgeous as when the lipstick is freshly applied. With SPF15 to boot, we honestly think this is the perfect red lipstick.
