The 595 nm pulsed dye laser has been reported to improve rhytides through nonablative mechanisms, minimizing the side effects and recovery period associated with traditional ablative resurfacing techniques. OBJECTIVE: The purpose of this study was to investigate the efficacy of the long pulse flashlamp pumped pulsed dye laser (LPDL) in improving rhytides and stimulating collagen synthesis and dermal remodeling. METHODS: The cheeks of 15 women with moderate to severe photoaging were treated on one side with a series of four monthly LPDL treatments, while the contralateral cheek was treated with cryogen coolant only. Clinical grading was performed at monthly intervals for up to 3 months after the fourth LPDL treatment. Skin biopsy before treatment and at 4-6 weeks was also performed for histologic evaluation and staining for type I procollagen. RESULTS : Eleven of 15 patients demonstrated improvement of the laser-treated cheek while only three of 15 patients the demonstrated improvement on the cryogen-treated cheek. A statistically significant ( p = 0.0035) improvement in clinical grading of photodamage was noted in the treated side versus the control. In those patients who improved with LPDL treatment, an improvement of 18.1% in the mean pre- and post-treatment clinical grading scores was observed. Histologic evaluation demonstrated an increase in activated fibroblasts with positive procollagen staining on the LPDL-treated cheek. CONCLUSION: The 595 nm LPDL may be used in the treatment of moderate to severe wrinkles. A mild improvement may be expected with minimal to no side effects.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"3 1","pages":"129 - 136"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/147641701753414933","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59955325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This ablative treatment, however, is associated with undesirable complications and long recovery times. A growing body of evidence suggests that dermal inflammation and subsequent collagen formation can be stimulated without removal of the epidermis, raising the possibility of effective non-ablative skin remodeling for mild to moderately photodamaged skin. MATERIALS AND METHODS : This preliminary study was performed to evaluate the safety and subject satisfaction of non-ablative skin remodeling using a 532 nm, 2 ms pulse-duration, frequency-doubled Nd:YAG laser. Subjects with mild-to-deep lip wrinkles and mild-moderate acne scarring were treated one half of their lip (wrinkles) or cheek (acne scarring), leaving the other side as an untreated control. Subjects were treated at 3-6 week intervals for an average of three treatments. Subjective assessment of improvement was estimated by subject self-evaluation of the percentage improvement over baseline, and a blinded observer attempted to identify the treated side on physical examination. RESULTS : Subjective assessment revealed an average improvement of 51.4% and 53.6% for upper lip wrinkles and facial acne scarring, respectively. Side effects were limited to transient erythema that resolved over 0.25-2 hours following treatment. CONCLUSIONS : These results demonstrate that non-ablative treatment with the 532 nm, 2 ms pulse-duration Nd:YAG laser results in subjective improvement of rhytides and acne scarring, with a high safety profile.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"3 1","pages":"137 - 141"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/147641701753414942","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59955360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The efficacy of Locobase Repair ® cream, which improves skin barrier function due to its content of natural skin analogue fats and cholesterol, was investigated. METHODS: A total of 18 Caucasian patients underwent resurfacing for acne scars. Laser treatment was performed with a Sharplan 1020 CO 2 laser and a Silk Touch scanner. Locobase Repair cream (a water-in-oil cream with 63% lipids including natural components of stratum corneum: cholesterol, ceramide and free fatty acids) was applied daily to one side of the face and petrolatum was applied to the other. In addition, both sides were treated with a 2% fusidic acid cream. RESULTS: There was a significant reduction of oozing during the first 2 days after CO 2 laser treatment on the sides treated with Locobase Repair cream ( p < 0.05), CO 2 laser while from day 3 to day 7 no differences were demonstrated between the Locobase Repair cream and petrolatum. For the other parameters scored (scaling, oedema, erythema and pain), no significant differences between Locobase Repair cream and petrolatum were found. Furthermore, no significant differences were found between the two creams regarding the duration of wound healing and final cosmetic outcome. In all, 62% of the patients preferred to use Locobase Repair cream during the postoperative period, and 11% preferred petrolatum. The remaining 27% expressed no preferences. CONCLUSION: The use of Locobase Repair cream as a post laser resurfacing treatment reduces tissue fluid oozing during the first 2 postoperative days, indicating a quick restoration of skin barrier and hence possibly a reduction in the incidence of wound infections as well as enhancing patient compliance due to less fluid oozing.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"3 1","pages":"155 - 158"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/147641701753414979","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59955443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The erbium:YAG laser (Er:YAG) with a wavelength of 2.94 w m allows precise ablation avoiding strong inflammation. The authors have evaluated the potential benefits of Er:YAG laser treatment for difficult-to-treat warts and actinic keratoses. PATIENTS AND METHODS: A total of 69 patients with difficult-to-treat warts (periungual or plantar) with a mean age of 30.1 - 16.1 years (range 11-58 years), and 29 patients with actinic keratoses with a mean age of 73.5 - 9.7 years (range 58-90 years) were treated by Er:YAG laser. Ablative therapy was performed with a spot size of 3 mm, a frequency between 8 Hz and 15 Hz, and a fluence of 5.7-11.3 J cm -2 (warts) or 5.7-7.1 J cm -2 (actinic keratoses). RESULTS: After a single laser treatment a complete response (CR) was observed in 50 patients with warts (72.5%). Plantar warts were more resistant (13.5% non-responder) compared with periungual warts (5.9% non-responder). Twelve patients with a CR showed a relapse within 3 months after treatment (24.0%). All but one suffered from plantar warts. Twenty-six patients with actinic keratoses showed a CR after a single laser treatment, and in three patients a partial response (PR) was achieved. None of the patients treated with Er:YAG laser developed pigment changes, wound infections or scarring. CONCLUSION: Treatment of common epithelial lesions such as common warts or actinic keratoses by Er:YAG laser is safe and effective. In patients with plantar warts, however, a significant rate of relapse may occur, requiring additional therapy.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"3 1","pages":"63 - 66"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/146288301753377852","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59798702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with darker skin phototypes (IV–VI on the Fitzpatrick scale) have a higher incidence of side effects. Hypopigmentation is due to a transitory cessation in melanin production and the mean clearance time is about 3 months. We present a case of long-term hypopigmentation induced by laser diode photo-epilation. A 22-year-old Caucasian female, phototype III (Fitzpatrick scale), with localized hypertrichosis on her forearms and no history of recent sunbathing or PUVA exposure, was submitted to our clinic for hair removal to be carried out by two monthly sessions with a diode laser. The applied laser technique emits a wavelength of 800 nm, has a pulse width of 5–30 ms, a spot size of 9 3 9 mm, and a 5°C chilled sapphire tip (LightsheerTM, Coherent Inc). During the Ž rst treatment session she received 286 pulses at a  uence energy of 23 J/cm. Immediate whitening, vesiculation, or forced epidermal separation (Nikolsky’s sign) was not observed during the procedure. Aloa vera gel and sunscreen (SPF 50) was applied to the skin immediately after the treatment, and the patient was instructed to continue to do so for 1 week, after which time she continued using only a sunblocker. Avoidance of sun/PUVA exposure for 2 weeks after treatment was recommended. One month later, during the second treatment session, she received 228 pulses at a  uence energy of 32 J/cm. Mild erythema was the only immediate side effect observed. However, 1 week postoperatively she complained about cutaneous hyperpigmented brown lesions on both forearms (Figure 1). Two weeks postoperatively, clinical examination demonstrated numerous hypopigmented round lesions on both forearms. At this time a topical corticosteroid cream (clobetasol 17-propionate 0.05%; ClovateTM, Medeva Pharma, Madrid, Spain) was introduced, twice daily, during two 10-day cycles. However, the hypopigmentation persisted (Figure 2). At that time she was instructed to maintain the sunscreen only application. By the Ž fth postoperative month no improvement of the hypopigmentation had occurred. Journal of Cutaneous Laser Therapy 2001; 3: 9–10 © Journal of Cutaneous Laser Therapy.

Shared tastes and emotions become determinant. The climate is changing: cultural values coded as ‘feminine’ are becoming widespread: sensitivity, emotion, aesthetics. This is a complex situation, a  uctuating identity. Identity today resides in a multiple register with the juxtaposition of different, opposed and ambivalent values and attitudes. People are deŽ ned simultaneously by ethics and hedonism, by tradition and by technology. We cope, we manage, we surf. Appearance, looks, attractiveness are invested with a new dimension. They no longer reside on the surface, at the level of social normality, but truly inside, the re ection of a serene balance between the internal and external. In parallel, despite a wide-ranging debate, one problem remains: we accept age only while it still embodies signs of youth. ‘To manage’ our appearance and ‘to optimise’ our beauty become complex and sometimes paradoxical strategies. Although attitudes and behaviours have changed, some factors can be seen to have remained constant. The body is perceived as a subject: we listen, we investigate, we invest, in short we ‘psychologise’. Modern philosophers and anthropologists (Michel Serres in France, Diane Ackerman in the USA) have also contributed to restoring to the sensory sphere a major role in the knowledge and understanding of the world and of oneself. Preoccupation with beauty is legitimized. It is based on an individualistic and wilful ideology: to be oneself, which corresponds to the best image of oneself. And this preoccupation becomes all the more consistent when it involves everything: nutrition, exercise, psychology, art. This constitutes both an opportunity, an all-pervasive consciousness, and a risk area: who does what? who is competent in this subject? In parallel, increasing self-analysis puts the accent on prevention, the global vision. It is the Ž eld of ‘energy’ therapies (homoeopathy, acupuncture, etc.) aiming to support this ‘holistic’ vision of the person. Finally, public cultural opinion is formed. Women’s magazines and the general press devote vast tracts to beauty. For the doctor specialising in beauty, all this creates a new conŽ guration of his status and his role. It is a challenge. He has to take account of the mental attitudes that are developing, with the globalisation of perceptions and expectations. He must act more preventatively, have a broader, more educational, more interactive purpose. It is an opportunity. He is one operator among many, but because of his status as a doctor he must strive to achieve a higher position with ‘intelligence’ of beauty. As Michel Serres said in ‘The Five Senses’: ‘Nothing goes as deep as adornment, nothing goes as far as the skin, the ornament and dimensions of the world.
