medicube Rosemary PDRN Scalp Serum 20ml

An unbalanced scalp eventually shows up in the hair itself. This concentrated serum from medicube starts from a straightforward idea: treat the problem at its root, quite literally. The 20 ml size slips into any travel bag, the mini gua sha applicator goes straight onto the scalp — and the cooling sensation it delivers says more about what's inside than any written claim ever could.

Texture and ingredients — Three key ingredients work together at the heart of this formula: rosemary extract (Rosmarinus Officinalis), PDRN (Sodium DNA, 100 ppb) — a polynucleotide DNA fragment known for its soothing properties — and EGF (sh-Oligopeptide-1), a peptide that supports the scalp's cellular environment. Ultra-fine hydrolyzed sponge spicules (Hydrolyzed Sponge) help distribute the ingredients evenly across the scalp surface. Caffeine and biotin round out the formula, while menthol and menthyl lactate deliver that instant cooling feeling. The lightweight, fast-absorbing texture leaves no greasy residue and keeps hair looking full at the roots.

How to use it — After shampooing, towel-dry your hair to remove excess water — the scalp should still be slightly damp, which helps the serum absorb better. The built-in gua sha applicator goes straight to the roots: a few slow, gentle presses, then circular massage motions for two to three minutes. The cooling kicks in right away. No rinsing, no extra steps. The 20 ml size works just as well for daily use on the go as it does for trying the product over three to four weeks before committing to a larger size.

• PDRN at 100 ppb (Sodium DNA): concentration listed on the formula sheet, active at a traceable dose.
• Hydrolyzed sponge spicules: natural micro-textures that help spread the serum evenly across the scalp.
• Built-in gua sha applicator: targeted massage with no hand contact, for more precise application at the roots.
• 20 ml size: ideal for testing the product over three to four weeks of regular use, or for travelling.
• Apply post-shampoo to a damp scalp — no rinsing needed, works with any styling finish (blow-dry or air-dry).
