Don't get me wrong, I love laser as much as the next Dermal Clinician but laser does pose as a higher risk treatment for some individuals and that's why I thought it would be useful to do a comparison of laser vs skin needling.
Laser and skin needling both cause a controlled micro injury.
The difference is how.
Laser uses heat to cause injury to the skin to initiate the immune system to come and rebuild the site and replace with better quality collagen. Whereas skin needling is a mechanical injury that leads to collagen production.
Heat is associated with destruction of the epidermal cells (cells located in the top layers of skin), scar collagen (TGF-B1 & B2), increase in melanogenesis (the production of pigment) and coagulation of tissue.
Laser Rejuvenation has a higher risk of:
- Pigmentation Changes
- Longer healing time
- A shiny appearance to the skin which can look unnatural
For all you skin geeks out there below is a comparison list of laser vs skin needling.
- Epidermal integrity preserved
- Increase dermal papillae
- Release of EGF, PDGF, VEGF etc
- Regenerative healing
- Breaks down scar tissue
- Natural collagen (TGF-B3)
- Does not affect melanogenesis (the creation of melanin)
- Initial epidermal destruction
- Loss of dermal papillae
- Coagulation of protein-based growth factors
- Cicatricial healing
- Scar collagen (TGF-B1 & B2)
- Increase in melanogenesis (creation of pigment)
Due to the non-thermal properties of skin needling, it is a suitable option for all skin types as the risks of pigmentation are significantly decreased. As long as the skin is well protected skin needling can be performed year round and the healing time is half that compared to laser rejuvenation, in-fact many say skin needling requires no-down-time. However, I always will state in consultations that redness may remain for several days.
