- Carries Betaine, which is a sugar beet-derived humectant that helps this formula feel less stripping on contact.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.

How it works
Exper True Toning Serum 30ml is THE LAB by BLANC DOUX's serum, sitting at the treatment step in a layered Korean routine. Niacinamide is the brightening, barrier-supporting workhorse behind most Korean tone-evening formulas, and it layers easily under sunscreen and makeup. Ascorbyl Ether is a Vitamin C derivative added for its brightening, antioxidant role. Betaine is a sugar beet-derived humectant that helps this formula feel less stripping on contact. That formula is what makes a serum worth sourcing specifically: the finish, glide and Korean-market ingredient sourcing are the same as what a shopper would buy off a Korean shelf. THE LAB by BLANC DOUX sells THE LAB by BLANC DOUX Exper True Toning Serum 30ml as one entry in a wider catalog, and this 30.0ml is sized the way Korean shoppers actually buy it rather than a US-market repack.
How to use
- Smooth a few drops over the face and neck after toner, letting the Niacinamide-led formula absorb before moisturizer; suited to both morning and evening use in a toning routine.
