Bio Roller G4

Fitted with 1,200 needles made of titanium steel, each 1.0 mm long, Bio Roller G4 is a manual derma roller for at-home microneedling of the face and scalp. It arrives in sterile packaging, and its protective cap is designed to double as a small disinfection tank for the roller head.

At a glance

  • Needle count: 1,200
  • Needle material: titanium steel
  • Length: 1.0 mm per needle
  • Cap: safety cover that also serves as a disinfection tank
  • Handle: ergonomic, for both facial and scalp use
  • Packaging: sterile before first use

Where it is used

The G4 is used to get the skin ready to take up suitable serums or boosters. It also features in routines that focus on visible fine lines, pore size and an irregular surface texture. When used on the scalp, it forms part of care routines for thinning-looking hair. The linked article on skin needling gives wider context, and the general principle behind microneedle technology is described in the Wikipedia overview.

Preparing the product

  1. Fill the cap with 70% isopropyl alcohol and soak the roller head in it for at least five minutes.
  2. Remove any makeup, wash the area with a mild cleanser, wash your hands and put on disposable gloves.
  3. Roll with light, even pressure in horizontal, vertical and diagonal directions, two to four passes each. Avoid pressing hard and do not aim to draw blood.
  4. A serum or skin booster can be applied afterwards.
  5. Clean and disinfect the roller, let it dry and keep it somewhere clean and dry.

At 1.0 mm, the stated interval is once every two to three weeks.

Handling and storage

The roller is a personal tool and should not be shared. Disinfect it before and after every session, keep it away from children, and keep it off any skin that is broken, irritated, inflamed or showing signs of infection.
