Depending on the situation, different sizes of needles are used for Microneedling; thus, you need to decide on what skin issue you are aiming at solving. For instance, if you want to treat acne as well as scars, a 1.5 to 2mm needle length is recommended, as it delivers exceptional results. On the other hand, if you want to solve ageing problems, such as wrinkles, fine lines, etc., 0.5 to 1.0 mm, needle length is appropriate. From both conditions, it is easier to say that the best size needle for Microneedling is 0.5 mm, as it penetrates the skin enough for correctional purposes.
