Key benefits
- Oligo Hyaluronic Acid Hydro Serum 50ml is THE LAB by BLANC DOUX's serum, sourced for the Korean market rather than reformulated for US shelves.
- Carries Sodium Hyaluronate, which is a salt-form humectant from the hyaluronan family, smaller and faster-absorbing than the parent molecule, and a staple of Korean hydration formulas.
- Carries Panthenol, which is provitamin B5, a humectant that helps a formula feel less tight after it dries down.
- Carries Allantoin, which is a calming, skin-conditioning agent frequently paired with soothing botanicals in Korean formulas.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting dehydration and a compromised moisture barrier.

How it works
Oligo Hyaluronic Acid Hydro Serum 50ml is THE LAB by BLANC DOUX's serum, sitting at the treatment step in a layered Korean routine. Sodium Hyaluronate is a salt-form humectant from the hyaluronan family, smaller and faster-absorbing than the parent molecule, and a staple of Korean hydration formulas. Panthenol is provitamin B5, a humectant that helps a formula feel less tight after it dries down. Allantoin is a calming, skin-conditioning agent frequently paired with soothing botanicals in Korean formulas. 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 Oligo Hyaluronic Acid Hydro Serum 50ml as one entry in a wider catalog, and this 50.0ml is sized the way Korean shoppers actually buy it rather than a US-market repack.

What professionals say
What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.
Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic Pantothenol is a common ingredient in skin care and hair products I recommend, particularly for people who are prone to dryness.
Taylor Bullock, MDDermatology resident, Cleveland Clinic

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic
