Our read on this product
Most serums either focus on clinical repair or simple moisture, but this one bridges the gap by acting as both a deep hydration treatment and a functional makeup primer. Because it uses polyglutamic acid, it holds onto water more tenaciously than standard hyaluronic formulas, leaving the skin feeling plumped rather than just damp. It absorbs cleanly, which is why you can layer it under foundation without dealing with the pilling or tackiness that often ruins a morning routine.
You will likely find yourself reaching for it on days when your skin looks particularly tired or dull, as the formula is designed to impart a subtle, glass-like glow immediately upon application. Since it is fragrance-free and formulated to be gentle, it avoids the irritation that often comes with high-potency serums, making it a safe addition to a routine that already includes active treatments or sensitive-skin care.
What makes it stand out
- Polyglutamic acid base provides a higher water-retention capacity compared to standard hyaluronic acid serums.
- Acts as a functional makeup primer, whereas many hydrating serums are strictly skincare-focused and can cause makeup to slide.
- Fragrance-free, non-sticky formulation specifically engineered for daily use under base makeup.
Real-world notes
- Absorbs cleanly into the skin without leaving a tacky or sticky residue behind.
- Provides a noticeable, immediate smoothing effect that makes foundation application feel more seamless.
- Works well as a standalone hydrator for those who prefer a minimalist, one-step morning routine.
- The texture is lightweight enough to layer easily with sunscreens or other skincare products.
Pick this up if you want a single morning step that hydrates deeply while creating a smooth, radiant canvas for your makeup.
