How Does Microneedling Work?
As we grow older, the cycle of new skin growth slows and less collagen and elastin are produced. This results in fine lines, wrinkles and dark spots (pigmentation).
Applying creams and serums on your face may succeed to moisturise the outer layer of dead skin, but no penetration takes place to the living part of the skin. The active molecules are simply too big to pass through the ultra protective epidermis layer.
Dr Pen creates “micro-channels” These are tiny punctures in the skin causing micro trauma, the body then creates a healing response promoting new collagen and elastin growth.
Further guidance
Microneedling allows deeper penetration of serums and ingredients resulting in higher efficacy, meaning you get more out of your serums than traditional application.
The depth setting used should be tailored to the area you are treating. As an example skin around the eyes is thinner and more sensitive than that of the cheek, therefore you should use a lower depth setting around the eyes. It also comes down to experience of use and confidence. Higher depth settings should only be used by professionals, if you are unsure consult with a dermatologist or doctor. Our guides and site content are not intended to substitute the advice of a trained physician or licenced health care professional.
Most Dr Pen microneedling pens have a speed range of 1-5.
As a general rule, the faster you set the speed on your microneedling pen, the deeper the needle will penetrate into your skin. Lowest speeds are recommended if you are a beginner. If using the pen on sensitive areas such as the face, lower speeds can help you achieve more precise control of the pen.
When working on the body such as scaring or stretch marks a higher speed works well, this can be built up gradually.
Only ever use a cartridge once

Which Cartridge?
12,18 & 24 Pin – These cartridges are ideal to improve acne scars, wrinkles, fine lines, melasma, rosacea, hyperpigmentation and collagen induction. Some people will opt to use a numbing cream on prepped and cleansed skin. Ultimately this depends on the depth, experience of the user and if they are using the device for a professional treatment or as an at home treatment.
36 & 42 Pin – These cartridges are ideal to improve skins hydration levels, visibility of stretch marks, visibility of large pores. These higher pin cartridges are good for treating larger areas. As with the lower pin cartridges some people will opt to use a numbing cream on prepped and cleansed skin. Ultimately this depends on the depth, experience of the user and if they are using the device for a professional treatment or as an at home treatment.
Nano s & r – These cartridges stay in the epidermis. They are great for BB Glow treatments and to improve skin tone. The can also be used to combat fine lines. Nano Needling also helps products penetrate the skin more easily and can encourage brow hair regrowth. Nano cartridges can be used more regularly which makes them ideal for use at home and will not require any numbing cream.
