Derma Roller Stamp Titanium Needles Skin Care System Used For Body&Face/Acne/Surgical/Burn Scars/Wrinkles/Stretch Marks/Enlarged Pores (Hydra Pen,0.5 mm)

This is a little bottle with few micro needles.It doesn’t seem to work as it suppose to, it has only tiny 1 hole to dispense the serum once pressed on the skin.It doesn’t really work

I love this stamp. Im using it on my lips and forehead where the pain is bearable compering with rollers.
