Equipment needed for microneedling
Microneedling can use pens or rollers.
| Advantages | Disadvantages | |
| Pen | Can adjust depths during treatments
Less likely to cause inflammatory conditions (PIH) |
Some pens can be expensive
Need to be charges and can lose charge during treatments if a cordless device |
| Roller | Easy to use
Quick to use |
Can cause more unnecessary trauma to the skin
Can get caught in the hair Cannot adjust depths |
Depths to use
During the treatment the practitioner is aiming to target the epidermal junction which is only a maximum of 1mm into the skin. Also area’s like the forehead and scalp are thinner and more bony so it would cause pain as the tissue is not as deep.
Needle choices
Needle cartridges come with a different amount of needles enclosed. Different brands will have a different number but the science is the same. The more needles there are the less trauma/pain to the skin (I know it sounds strange). Think of it like a bed of nails, the more nails the more comfortable it is to lay on!
Use this as a guide-
9 Pin- not suitable for the scalp, more designed for the body
12 pin –The most common size to use
36 pin- less trauma and pain
42 pin- less trauma and pain
Nano round- painless, superficial depth, hydrating, can be used near the eyes, often used in BB glow treatments, inducing eyebrow hair growth, fine lines, improving product penetration.
These can be used weekly for hydration
Points to remember-
- The higher amount of the needles there are the thinner the needles will be.
- Thinner needles are better for collagen induction therapy (CIT). Also, less pain, less damage and faster recovery
- The lower the amount of needles, in a cartridge, means the needles are thicker
- Thicker needles will have more discomfort and a longer recovery time
