Product Guide
Abib PDRN Glow Serum 4.0 Pump is a 30ml pump serum built around 4% sodium DNA, with niacinamide, panthenol, hyaluronic acid, collagen and several peptides. The pump format makes it different from the dropper bottles used by many PDRN serums.

Useful if: choose it if you want a lightweight pump serum with high PDRN positioning and a broad supporting peptide formula.
The airless pump keeps application simple and measured without a dropper. That can be useful if you prefer a quick serum step or dislike handling pipettes.
The texture is designed to layer before moisturiser, so the format is more important as a convenience difference than as a different routine step.
Abib lists sodium DNA at 4%, alongside niacinamide, panthenol, hyaluronic acid, hydrolysed collagen and six peptide ingredients. The brand describes the PDRN as salmon derived.
This is still topical skincare. The PDRN percentage does not make the serum equivalent to injectable polynucleotide treatment.
Apply after cleansing and toner, then follow with moisturiser. It can be used morning or evening according to the brand directions. If you already use another PDRN serum, there is little reason to layer several products purely because they share the same headline ingredient.
