This serum from THE LAB by BLANC DOUX features oligo hyaluronic acid, a form of low-molecular-weight hyaluronic acid designed to penetrate deeper into the skin for layered hydration. The 85ml / 2.87 fl oz formula aims to support a dewy, plumped appearance and a smooth, radiant complexion often described as glass skin or glow skin. It can be used as a prep step before makeup to help create a hydrated base that allows foundation or cushion products to apply more evenly.

The lightweight texture absorbs quickly without leaving a sticky or heavy residue, making it suitable for various skin types including combination, normal, and dehydrated skin. The absence of excessive oils may appeal to those who prefer a breathable finish. Regular use is intended to maintain skin’s moisture balance, contributing to a visibly more luminous and supple surface.

This product focuses on delivering hydration through a multi‑molecular approach, with the oligo hyaluronic acid working alongside other moisture‑retaining ingredients. It does not claim to alter skin structure or produce immediate dramatic changes, but rather supports daily skin conditioning. The formula is crafted to be gentle, with attention to minimizing common irritants in line with many Korean skincare approaches.

Suitable for those looking to enhance skin’s natural glow without heavy layering, this serum can be incorporated into both morning and evening routines. It functions as a hydrating step that pairs well with subsequent moisturizers or sunscreens. The 85ml bottle offers a practical quantity for regular application, allowing users to experience the effects of consistent, targeted hydration over time. As with any skincare product, individual results may vary based on skin condition and overall regimen.
