THE LAB by blanc doux Oligo Hyaluronic Acid Deep Glow Serum

Glow doesn't always need scrubbing — sometimes it just needs the right acid.

This Deep Glow Serum from THE LAB by blanc doux centers on Hydrolyzed Hyaluronic Acid at 3,000ppm — a smaller, more penetrating form than standard hyaluronic acid — paired with Gluconolactone, a gentle PHA that supports surface renewal without the sensitivity risk of stronger acids.

Hydroxyacetophenone works alongside to calm and stabilize skin while the PHA works, and Arginine supports the skin barrier so the exfoliating side doesn't compromise hydration. The result leans toward brightness and smoothness rather than aggressive resurfacing.

Lightweight, watery serum texture that absorbs fast — layer it in after toner for a hydration-plus-glow step, especially if your skin is dull but too reactive for stronger AHAs.

FAQ

What's the difference between this and the Boosting Ampoule?
This Deep Glow Serum focuses on brightening and gentle renewal with Hydrolyzed Hyaluronic Acid and the PHA Gluconolactone, while the Boosting Ampoule focuses more purely on deep hydration.

Is Gluconolactone gentle enough for sensitive skin?
PHAs like Gluconolactone are generally considered gentler than AHAs/BHAs because their larger molecule size limits penetration, and this formula pairs it with soothing Hydroxyacetophenone and barrier-supporting Arginine.

How much hyaluronic acid does this serum contain?
It contains Hydrolyzed Hyaluronic Acid at 3,000ppm.
