Anua PDRN vs Medicube PDRN — the blue bottle or the pink one? We stock both, we have used both, and mums ask us to choose between them almost weekly. The honest answer: they share the same hero ingredient but chase different goals — the Anua is a hydration-first serum, the Medicube is a firming-first serum. Which one is right depends entirely on which sentence sounds more like your mirror.
What they share
Both are built on PDRN, the salmon-DNA-derived repair ingredient Korean clinics have used for years (full explainer: what is PDRN?). Both are gentle, fragrance-conscious, pregnancy-appropriate and layer with everything. Both carry the same single flag: salmon-derived, so fish-allergy skin sits these out.

The blue bottle: Anua PDRN Capsule 100
The Anua serum pairs PDRN with multi-weight hyaluronic acid in its capsule system. Its personality is water: deep, lasting hydration and that plump, glassy, awake look. If your mirror sentence is "my skin looks tired, flat and thirsty," this is your bottle. It is the hero of our 4-Minute Ritual for exactly that reason — dehydration is the most common mum-skin complaint there is. (Yes, it is also the serum from the brand Kendall Jenner now fronts globally — the mums were here first.)
The pink bottle: Medicube PDRN Pink Peptide
The Medicube serum pairs PDRN with peptides and niacinamide. Its personality is structure: supporting the look of firmness, bounce and even tone. If your sentence is "my skin feels less springy than it used to," the pink bottle is the pick — it is the treatment step in both our Pregnancy-Safe Routine and the post-feeding Bounce-Back Ritual, because peptides are the pregnancy-appropriate answer to the firming slot.

Questions mums ask
Can I use both? You can — blue in the morning for the day-long plump, pink at night for the firming shift. It is a lovely (if indulgent) pairing, not a requirement.
Which for pregnancy? Both are considered pregnancy-appropriate. We build the vetted pregnancy box around the pink one because the firming support matters most in that season — but the blue is equally fine to use.
Which shows results faster? The blue — hydration is visible in days. The pink plays the longer firming game of weeks. Different clocks, both honest.
The ready-made route
If hydration and glow is your battle, the 4-Minute Ritual is built around the blue bottle with the cleanse, calm and seal steps that make it shine. If firming is the mission, the pink bottle leads the Pregnancy-Safe Routine (during the baby chapter) and the Bounce-Back Ritual (after feeding, when retinal joins it). Or compare everything in the full bundles.
