King Vic
Bar roller

The beard roller from King Vic made a good impression in our test.
This is a beard care product that has been specially developed for men with beards or a desire for a beard. It has a roller head with 200 genuine titanium needles that are 0.5 mm long. This length has been determined to be optimal and safe for beginners and advanced users who want to use the beard roller daily.
Using the beard dermaroller can lead to healthier and thicker beard growth.
Microneedling with the beard roller significantly improves the skin’s absorption capacity, so that beard care products can develop their full effect.
The King Vic brand stands for quality and offers a 100% satisfaction guarantee. If you are not satisfied with the product, you can return it within 30 days and get your money back. The company is convinced of the quality of the beard roller and wants to give its customers confidence in the product.

The outer carton

The King Vic bar roller was delivered in a simple cardboard box. The box was undamaged and easy to open. Inside the box was an outer box that was adapted to the product. The bar roller itself was in a plastic sleeve. The plastic and paper wrapping around the case would not have been absolutely necessary, but it protects against dirt and damage. In this case, the product was fully protected and the bar controller was therefore in perfect condition.
The product packaging is not fully recyclable.
The bar roller makes a good impression at first glance.

The bar roller on the side and the case

The bar roller is made of coated plastic and has a dynamic design. It is small and handy.
Thanks to the coating, the handle is non-slip and secure in the hand.
The needles on the head of the roller are only 0.5 mm long and are made of titanium, which makes them robust and durable. The handle of the beard roller sits comfortably in the hand and enables precise control during microneedling.
Due to the good quality, a long service life can be expected.

This is what our practical test showed

Overall, the King Vic bar roller makes a high-quality impression and is comfortable to hold. It is easy to use . Using it on the face takes some getting used to at first but is not very painful.
For safe use, it is advisable to clean the roller head before each use. It is then rolled vertically, horizontally and diagonally approx. 5-10 times over the beard areas to be treated. The micro-needles of the roller cause microscopic injuries to the skin under the beard, which stimulates skin regeneration. This allows the skin to better absorb beard care products such as beard oils or beard serums, as these penetrate deep into the follicles and promote the growth of new beard hair.
The King Vic beard roller has an optimum needle length that is ideal for beginners. No negative reactions have been observed, even with sensitive skin .
The product corresponds to the description and offers good value for money. Visible results only appear after a few weeks .
Overall, the beard roller has met expectations. It is easy to use, sits comfortably in the hand and does not cause any pain.
