Just a few short years ago, a special edition like this would have been considered science fiction. It is worth taking a moment to think about where we have been, how far we have come, and where we might be heading. Those of us old enough to remember the early collagen and laser days can only marvel at the progress. Back then, to paraphrase the old proverb, everything did look like a nail. Once progress started, it came with a vengeance. Radio frequency, intense pulsed light, fractional lasers, cryolipolysis, ultrasound, microwave, millisecond, microsecond, picosecond, and the list goes on. Acne scars, sweat, fat, red lesions, brown lesions, skin cancers etc; this list continues as well, and new challenges await. The field of noninvasive procedural dermatology is relatively old, dating back to early laser work by such pioneers as Leon Goldman, Richard Fitzpatrick, Rox Anderson, and Kenneth Arndt. However, rapid advances are a testament to several factors, including technology, physician aptitude, consumer demand, and available corporate funding for research and development. In this context, the future may bring challenges. Consumer demand is likely to remain high, the number of physicians with the skill and interest in using technology is expanding, and innovation shows no signs of slowing down. Whether companies will be financially stable enough to continue support of scientific exploration, as well as remain viable through Food and Drug Administration approval, remains to be seen. The development process for technology is expensive, and it is one of the cautionary links in the chain. The other challenge that looms is physician training, and with it brings two concerns. First, for noninvasive procedures to blossom, we must provide training both during and after residency for physicians to become skilled. The second concern is not new, but that does not diminish its importance, that is, ethics. Providers with a variety of motives have shown interest in the field, including those with minimal skills and/or without MD/DO degrees. It is incumbent on us to ensure basic ethical and skill standards are met, not only to safeguard our patients, but also to protect the future and integrity of our specialty. In this issue of Seminars in Cutaneous Medicine and Surgery, innovative therapies for body contouring will be discussed, including low-level laser therapy, cryolipolysis, and highintensity focused ultrasound. Although each technique has demonstrated promising results, a full characterization of the risks and benefits will likely be realized in the coming years as they are further adopted into clinical practice. The field continues to grow in other directions as well. Low-level laser light therapy can also be used to treat a multitude of common medical conditions, including wound healing, viral infections, and acne. Hyperhidrosis, a relatively common condition that can have a drastic impact on a patient’s quality of life, has disappointing responses to some current noninvasive therapies. In this issue, the use of microwave technology in hyperhidrosis will be discussed, giving providers a promising therapy in their armamentarium. Finally, laser and light devices are increasingly being sought after as an alternative to surgical techniques for skin rejuvenation and also tightening. In this issue, novel non-invasive approaches to facial tightening will be discussed, including the use of radio frequency and microfocused ultrasound. While procedural dermatology is still evolving, the robust development of new therapies, and novel applications of existing therapies, continues to push the limits of what can be done non-invasively. As experience with each modality becomes more defined, providers will be able to choose therapies more selectively for each patient. It is, indeed, a bright time for the field of procedural dermatology, with increasing capabilities and rising patient demand helping to ensure the future success of the field.
