I compared 3 different 192 needle dermaroller brands

Here is the difference between Gin Amber Beauty dermaroller and others. It's very important what is inside the roller head and how it is made, most of the companies they make rollers out of metal wheels inside (cheap production). No one serious company caring about longterm skin benefits would sell rollers made of metal discs. Get Gin Amber dermaroller HERE: https://ginamber.com use code SKIN20 for 20% OFF.
