There are many treatment options available to improve the appearance and texture of the skin, or to treat acne and acne scars. The method of choice in the last few years has involved laser technology, either to remove the outer layers of the skin to promote new skin growth (CO2 or Er:YAG), or to penetrate the skin to promote rejuvenation from within (fractional thermolysis).
Although effective for treating a variety of skin conditions, they do have their limitations, and in particular can cause hypopigmentation, areas of uneven skin colour, lasting up to two years after treatment. Fractional lasers were safe, but less effective, and required more treatments to achieve acceptable results.
A more recent development has been fractional thermolysis using radio frequency (RF) energy, instead of laser energy, to stimulate skin rejuvenation that is as effective as laser energy, but has a much lower risk of side effects. The leading device that uses RF energy is the eTwo SublativeTM Skin Treatment System. This article explains the science behind radio frequency energy and why it is effective for acne scar treatment.
