For non-specific tissue heating as in skin rejuvenation systems do not have a specific chromophore! But till recently we have been on the lookout for the ‘ideal’ wavelength. Er-YAG, Er-Glass, CO2 all have been tried with limited success though the fractional technology has improved the safety profile considerably.

Innovations happen when dogmas are challenged!
Scientists from Philips Research in Eindhoven have prototyped a system that do not depend on selective photothermolysis and hence not on any specific chromphore/wave length. The new system uses advanced optics to focus a laser beam below the epidermis. High laser intensity at the focal point induces a little known (to me) phenomenon called ‘Light Induced Optical Breakdown’ (LIOB) creating a mini ‘explosion’ along a short distance!

This conceptually different system has many advantages. Since it uses a converging beam, the laser intensity on the surface is very less and hence the surface changes and pain are virtually nil. However the sub-epidermal effect is similar to or probably more than ablative systems. So you end up giving ablative results at no pain and no downtime.
This should bring a paradigm shift in the present selective photothermolytic systems.
I give full five peels for this technology.
What is peel score?
