What discount percentage converts best for abandoned beauty products?

As a beauty brand owner running a Shopify store, abandoned carts are my constant nemesis. I'm seeing roughly 70% of potential customers adding products to their cart but never completing the purchase. My products aren't cheap—we're talking premium skincare with ingredients like hyaluronic acid and peptides—so I can't just throw random discounts around. I need a strategic approach that feels genuine and doesn't devalue my brand. When I look at my analytics, I notice mobile users are particularly prone to cart abandonment. They'll browse, add something to cart, and then get distracted. I'm desperate to understand the sweet spot for a discount that actually motivates a purchase without making my carefully crafted products seem less valuable. Is there a magic percentage that says 'compelling deal' without screaming 'desperate sale'? My margins are tight, so every percentage point matters. I need a solution that's smart, targeted, and doesn't just give away margin to people who were already going to buy.
