The myth of microneedling (i.e. dermarolling or dermastamping) is that it can restore the beautiful glowing skin you used to have by increasing blood supply, encouraging tissue formation and collagen production.
Microneedling works by penetrating the dermis (middle layer of your skin) to kick-start collagen production. These controlled injuries force the body to respond by healing the treated areas quickly and efficiently. Collagen is formed to repair and rebuild the tissues.
Sounds good right…? INCORRECT.
Doing this actually depletes your collagen over time and accelerates the ageing process. To understand this we must first understand ageing – which can be represented here as the accumulation of changes in a human over time.
Your skin, the largest organ on your body, is continuously exposed to destructive elements in the environment. Damage accumulates over time and your body repairs that damage and regenerates cells.
However, as we age, the ability of the body to make more collagen slows down and eventually stops (cellular senescence). I.e. the more you physically damage (age) your skin the more you negatively impact its ability to heal and regenerate. Consequently, collagen synthesis will deplete sooner (see appendix 1).
Think about it - If you fall over and scrape your knee your body will heal and produce fresh skin to replace it, but its capacity to do this diminishes the more it happens.
Even Wolverine's healing factor burnt out eventually bro...
Furthermore, any collagen made from the physical trauma of microneedling is a stress response by the body and comes at the price of killing live skin cells; collagen, elastin, and other components involved in maintaining the structural integrity of the cell.
In conclusion: avoid this gimmick and instead promote natural collagen production by stimulating healthy skin cell turn over. Good nutrition, hydration, sleep and skin care regimen are key.
N.b. this relates to microneedling on healthy skin. I have no strong opinions on microneedling for hair loss or to address scar tissue. The existing research on microneedling is mainly around scar tissue not healthy skin and there appears to be good evidence for its effectiveness (although there are no large controlled trials with extensive follow-up, so we don't know the long-term effects).
