Laser and light skin rejuvenation have changed dramatically in the last 10 years. CO and erbium:YAG remain the main wavelengths, but fractional, nonablative, and combination devices have been added. For those patients with lighter skin types and extensive photodamage and rhytids, full-field ablative laser resurfacing remains the procedure of choice. Read More

BACKGROUND: Fractional photothermolysis (FP) is a popular treatment option for photodamaged skin and addresses shortcomings of ablative skin resurfacing and nonablative dermal remodeling. Previous studies have demonstrated that FP using the 1550nm wavelength has led to improvement of ultrastructural changes and clinical effects associated with photodamaged skin in the deeper dermal structures, while treatment with the 1927nm wavelength has shown clinical effects in the superficial dermis. Both wavelengths produce precise microscopic treatment zones (MTZs) in the skin. Read More

Background: Currently, the isotretinoin (13-cis-retinoic acid) package insert contains language advising the discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. It is common practice to follow this standard because of concerns regarding reports of sporadic adverse events and increased risk of scarring.

Objective: To develop expert consensus regarding the safety of skin procedures, including resurfacing, energy device treatments, and incisional and excisional procedures, in the setting of concurrent or recent isotretinoin use. Read More

In this study were described the results, by tridimensional imaging evaluation, of the new "Combined Fractional Resurfacing" technique with the first fractional laser that overtakes the limits of traditional ablative, nonablative fractional resurfacing by combining CO ablative and GaAs nonablative lasers. These two wavelengths can work separately or in a mixed modality to give the best treatment choice to all the patients. In this study, it is demonstrated that the simultaneous combination of the CO wavelength (10600 nm) and GaAs wavelength (1540 nm) reduced the downtime, reduced pain during the treatment, and produced better results on fine wrinkles reduction and almost the same results on pigmentation as seen with 3D analysis by Antera (Miravex).

Since its introduction in 2004 by Manstein et al, fractional resurfacing has revolutionized the manner in which we treat photoaging. Fractional resurfacing delivers microscopic beams of light to the skin resulting in coagulation or vaporization of fragments of the epidermis and dermis. The wavelengths of these devices may vary, yielding different clinical results. Read More

By utilizing resurfacing lasers, physicians can significantly improve the appearance of sun-damaged skin, scars, and more. The carbon dioxide and erbium:yttrium-aluminum-garnet lasers were the first ablative resurfacing lasers to offer impressive results although these earlier treatments were associated with significant downtime. Later, nonablative resurfacing lasers such as the neodymium:yttrium-aluminum-garnet laser proved effective, after a series of treatments with less downtime, but with more modest results. Read More

Since the early 1980s, the field of skin rejuvenation has evolved rapidly. Traditional ablative resurfacing with carbon dioxide and Er:YAG lasers offered dramatic improvement of the skin tone and texture, but prolonged postoperative period and an increased risk for side effects and complications were unacceptable for the majority of patients. It prompted the development of nonablative lasers and non-laser systems, which stimulate dermal neocollagenesis without epidermal disruption, and therefore, produce less adverse effects with little or no healing time.

Pain is a common patient complaint with dermatologic laser procedures and effective pain management is important for the comfort and satisfaction of patients undergoing these procedures. Many topical anaesthetics are available as options to decrease the pain associated with these procedures, although not all have the same degree of safety. An FDA-approved lidocaine and tetracaine topical anesthetic cream [Pliaglis®, liodocaine and tetracaine 7%/7% cream (LT cream), Galderma Laboratories LP, Fort Worth, TX] is safe and effective when used with common laser therapies such as ablative and nonablative laser resurfacing, laser hair removal, laser treatment of vascular lesions, and laser tattoo removal.
