Ablative versus non-ablative
Do you know the difference between ablative and non-ablative skin rejuvenation treatments?
Ablative treatments involve some destructive energy being applied to the skin, which means that the cells in the layer of the skin closest to the surface, namely the epidermis, are damaged or ablated.
Plexr is a good example of an ablative treatment. The plasma energy destroys the superficial layer of cells, stimulating new cells to be regenerated to replace the old ones. This means the skin is renewed and tightened up.
Intense pulsed light is a good example of a non-ablative treatment. The light energy stimulates the cells to produce new collagen, but in a non-destructive way. So less down-time and less risk of adverse reactions.
What are the pros and cons?
Ablative treatments are more aggressive and therefore more effective at getting a quicker result, but their downside is that there is more risk of problems and more downtime. Non-ablative treatments get slower results but the effects can (eventually) be just as dramatic but without the risks of ablative treatments and much less, if any, downtime. Pelleve is another example of a non-ablative treatment.
