The Lab by Blanc Doux Clear Hyal Dewy Booster Ampoule 30 ml

The Gist

The Lab by Blanc Doux Clear Hyal Dewy Booster Ampoule 30 ml is a runny, water-like hydrating serum marketed as a dewy primer. The texture is distinctly thin and non-sticky, making it suitable for layering under moisturizer or foundation without visible residue. Application requires care; the consistency invites spillage, and many users decant into their palm first.

What Korean reviewers say

Korean shoppers consistently praise this ampoule as a makeup-prep foundation, reporting smoother application and longer wear when skin is pre-hydrated. However, feedback tempers the “dewy” marketing claim—reviewers describe the hydration as internal and steady rather than luminous. Multiple users noted the formula works best for dry skin and may feel occlusive on oily or sensitive skin in summer; one reviewer called it “unremarkable” as a standalone product and questioned whether it justifies repurchasing over competing ampoules at other retailers. Synergy with other The Lab by Blanc Doux products was mentioned anecdotally but not systematically validated.

Bottom line

At $3.70, this is a low-risk impulse buy for dry-skinned shoppers who want a hydrating primer layer or a travel-size backup. It is not a dramatic performer or a universal skin fix—it suits a specific use case (makeup prep, dry skin, warm seasons) and may disappoint those expecting visible dewiness or oily-skin compatibility.
