0.75 mm Derma Roller - The Lotus Roller - the only brand of Derma scooters - which were made available to the public and are long enough to apply collagen at home. Ensuring quality and sterility ~ Lasts 1 year in contrast to other brands (Misc.)
I am glad that I have found a good supplier for these scooters size, as many vendors offer only 1.0mm variant. This is a good alternative for me, because I can use it to treat my acne scars, without making the treatment through the 1.5mm needles too
