Wound Healing Treatments After Ablative Laser Skin Resurfacing: A Review.

Laser resurfacing has progressed since the 1980s to treat a variety of medical and aesthetic indications with ever-evolving safety parameters. While laser technology has evolved to provide a more favorable safety profile and decrease wound healing time, advances in post-procedure healing agents have also helped to mitigate adverse effects, such as persistent erythema, dyspigmentation, acneiform eruptions, dermatitis, infections, and scarring. We reviewed the evidence of growth factors, stem cells, silicone and silicone polymers, botanical based treatments, fatty acids, probiotics, and closed dressings on post-ablative laser skin resurfacing. All reviewed agents demonstrated some evidence in improving post-procedure outcomes, albeit mixed in many cases. Additionally, these studies contain small numbers of participants, vary in type, strength, and clinical indication for which the resurfacing laser was used, and have differing postprocedural evaluation protocols and assessments. This highlights a need for standardization of clinical studies and the importance of choosing an optimal postprocedural skincare plan depending on every unique clinical scenario.

Ablative Skin Resurfacing

Ablative laser resurfacing has evolved as a safe and effective treatment for skin rejuvenation. Although traditional lasers were associated with significant thermal damage and lengthy recovery, advances in laser technology have improved safety profiles and reduced social downtime. CO2 lasers remain the gold standard of treatment, and fractional ablative devices capable of achieving remarkable clinical improvement with fewer side effects and shorter recovery times have made it a more practical option for patients. Although ablative resurfacing has become safer, careful patient selection and choice of suitable laser parameters are essential to minimize complications and optimize outcomes. This article describes the current modalities used in ablative laser skin resurfacing and examines their efficacy, indications, and possible side effects.

Laser treatment for post acne scars– A review

Background: For years, there was no successful treatment for acne scars. Now, things have changed. With the development of new technologies, those suffering from acne scarring have multiple options to improve the tone and texture of the skin. Laser treatments, including ablative and non ablative laser skin resurfacing are among available treatment options. Methods: The aim of writing this paper is to review information about acne scarring, as well as potential treatments by laser. The paper will first concentrate on introduction and classification of acne scarring, then go on to treatment modalities specifically by laser. This paper will also focus on post treatment recovery time, side effects and methods to prevent and treat those side effects. Conclusion: Ultimate goal of any intervention in acne scarring is not total cure or perfection; rather it is making scars less visible.

Fractional ablative laser skin resurfacing: A review

Ablative laser technology has been in use for many years now. The large side effect profile however has limited its use. Fractional ablative technology is a newer development which combines a lesser side effect profile along with similar efficacy. In this paper we review fractional ablative laser skin resurfacing.

Punch excision combined with erbium:YAG fractional laser: Its application on different types of scars in Asian patients (a pilot study)

Scars cause significant impact on the quality of life of the affected patients and compel the search for more effective treatments. Ablative laser skin resurfacing, either alone or in combination with other modalities, is the gold standard for treating various scars but is associated with prolonged recovery and many side effects. To address these limitations, newer modalities employing the principle of fractional photothermolysis have emerged. Herein, we investigated the combined effect of punch excision and the erbium:YAG (Er:YAG) fractional laser on different types of scars in Asian individuals.

Cosmetic Surgery Survey of American Society of Oculoplastic and Reconstructive Surgery Members and a 6-Year Comparison

To examine the current cosmetic practices of American Society of Oculoplastic and Reconstructive Surgery members using a survey and compare those results with a similar survey that was performed 6 years prior, and to determine the types and breadth of cosmetic procedures that are currently performed within the field of ophthalmic plastic and reconstructive surgery. A 49-question survey was sent to members of American Society of Oculoplastic and Reconstructive Surgery by post mail and/or electronic mail in 2007. The questions covered surgeon demographics, cosmetic practice design, and preferences for aesthetic procedures and commercial equipment and products. Frequencies and percentages of responses were obtained for each question individually. Responses to similar questions in a 2001 survey were compared with those in the current survey. Two hundred fifty-seven members of 488 responded (53%). Eighty-two percent of respondents (208 of 253) performed some type of cosmetic procedure. Fifty-five percent of respondents reported that less than 25% of their practice consisted of cosmetic procedures and services. Thirty-one percent of respondents reported that 25% to 75% of their practice was cosmetic. A slightly higher percentage of respondents reported that more of their practice consisted of cosmetic procedures and services compared with 6 years ago; however, the difference did not reach statistical significance (p = 0.895). A lower percentage of respondents injected Botox cosmetic (p = 0.02), offered ablative laser skin resurfacing (p < 0.001), and performed rhytidectomy (p < 0.001) in 2007 compared with 2001.

Fraxel Laser Indications and Long-Term Follow-Up

Fractional photothermolysis, based on creating spatially precise microscopic thermal wounds, is performed using a 1550-nm erbium fiber laser that targets water-containing tissue to effect the photocoagulation of narrow, sharply defined columns of skin known as microscopic thermal zones. According to the authors, Fraxel resurfacing has been shown to be both safe and effective for facial and nonfacial photodamage, atrophic acne scars, hypopigmented scars, and dyspigmentation. Because only a fraction of the skin is treated during a single session, a series (typically 3 to 6 treatments) of fractional resurfacing at 2- to 4-week intervals is required for the best clinical improvement. It is the authors' experience that a series of Fraxel treatments can achieve a similar clinical result for atrophic scars compared with traditional ablative laser skin resurfacing. However, the improvement seen after a series of Fraxel treatments for perioral laxity and rhytides often falls short of the impressive results that can be achieved with ablative laser skin resurfacing.

Combination surgical lifting with ablative laser skin resurfacing of facial skin: a retrospective analysis.

Cutaneous aging is manifested by rhytides, dyschromias, and skin laxity. Ablative laser skin resurfacing can effectively improve many signs of skin aging; however, the photoaged patient with facial laxity often requires a surgical lifting procedure in order to obtain optimal results. Concerns with delayed or impaired wound healing has led to reluctance to perform both procedures simultaneously. To report the clinical results and side effect profiles after concomitant surgical facial lifting procedures and ablative carbon dioxide or erbium:YAG laser resurfacing in a series of patients. A retrospective analysis and chart review was performed in 34 consecutive patients who underwent combination CO(2) or erbium:YAG laser skin resurfacing and surgical lifting procedures, including S-lift rhytidectomy, blepharoplasty, and brow lift. Side effects and complication rates were tabulated. The side effect profile of the combined surgical-laser procedures was similar to that reported after a laser-only procedure. The most common side effect was transient hyperpigmentation which occurred in 20.6% of treated patients. None of the patients experienced delayed reepithelialization, skin necrosis, or prolonged healing times. Concurrent laser skin resurfacing and surgical lifting of facial skin maximizes aesthetic results without increased incidence of adverse effects. Patients benefit from the consolidation of anesthesia and convalescent times as well as enhanced global clinical outcomes.

Improvement of dermatochalasis and periorbital rhytides with a high-energy pulsed CO2 laser: a retrospective study.

Upper eyelid dermatochalasis is typically treated with excisional blepharoplasty. The role of the CO2 laser previously had been confined to that of a vaporizing, incisional, or hemostatic tool. Over the past several years, however, ablative CO2 laser skin resurfacing has been popularized as an adjunctive treatment to blepharoplasty to minimize periorbital rhytides through its vaporizing as well as skin-tightening action. To evaluate the safety and efficacy of a high-energy pulsed CO2 laser as a stand-alone treatment for dermatochalasis and periorbital rhytides. Sixty-seven patients (skin phototypes I-IV) with mild-to-severe upper eyelid dermatochalasis and periorbital rhytides received periocular CO2 laser skin treatment. Global assessment scores of dermatochalasis and rhytides were determined by a side-by-side comparison of periocular photographs preoperatively and 1, 3, and 6 months postoperatively. In addition, caliper measurements of upper eyelids before and 1, 3, and 6 months after treatment were obtained. Both dermatochalasis and periorbital rhytides were significantly improved after periocular CO2 laser skin resurfacing. Patients with more severe dermatochalasis and rhytides showed greater improvement after CO2 laser treatment than did those with mild or moderate involvement. Side effects were limited to erythema and transient hyperpigmentation. No scarring, hypopigmentation, or ectropion were observed. Periocular skin resurfacing with a CO2 laser can safely and effectively improve upper eyelid dermatochalasis and periorbital rhytides.

Are all infrared lasers equally effective in skin rejuvenation.

In an attempt to limit the prolonged postoperative healing associated with ablative laser skin resurfacing and in response to growing public interest in less invasive treatment modalities, nonablative laser and light source technology was developed. Over the past few years, several clinical and histologic research studies have been conducted to determine the relative efficacy of these nonablative systems. These systems stimulate dermal collagen remodeling using wavelengths and concomitant tissue cooling that limit injury to the epidermis, thereby minimizing or eliminating postoperative sequelae. While nonablative lasers do not supersede already established ablative laser technologies, they supplement the treatment armamentarium, making a wider range of treatment options available and enhancing the ability to correlate the needs of individual patients more closely with the specific advantages offered by a particular modality.
