Medicube Rosemary PDRN Scalp Serum 20ml

A tired, irritated scalp needs more focused care than a regular shampoo alone can offer, and that’s where Medicube Rosemary PDRN Scalp Serum (20ml) comes in. This concentrated serum comes with a rollerball-style applicator that delivers a cooling sensation, designed to soothe the scalp and support a healthier environment for stronger, fuller-looking hair.

This serum comes from Medicube, a Korean brand well known among fans of Korean skincare products for scalp and hair care. The formula relies on fine Spicule technology that helps distribute active ingredients more deeply into the scalp, combined with PDRN, caffeine, niacinamide, and rosemary extract.

How to Use

After shampooing and lightly towel-drying, part the hair and apply the serum directly to the scalp — focusing on the temples, crown, and hairline — using the included rollerball applicator, and gently massage until fully absorbed. Important: due to the Spicule technology in this formula, limit use to once or twice a week maximum, not daily.

Best Suited For

Well suited for dry, irritated, or flake-prone scalps, and a good option for anyone looking for intensive care that supports scalp health and helps improve the look of hair density.

Warnings

For external use on the scalp only. Contains fine Spicule technology, so use should be limited to once or twice a week maximum — avoid overuse. Also contains acids (salicylic and glycolic), so a patch test is recommended before first use. Avoid direct contact with eyes — if contact occurs, rinse thoroughly with clean water. Keep out of reach of children.
