Lasers Med Sci 2024; 39:80. [PMID: 38396012 DOI: 10.1007/s10103-024-04028-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 02/18/2024] [Indexed: 02/25/2024]
Abstract
PURPOSE This split-face randomized study compared the efficacy and safety between 1064-nm picosecond laser with fractionated microlens array (MLA) and 1565-nm nonablative fractional laser to treat enlarged pores. METHODS Participants with enlarged facial pores were enrolled and underwent three consecutive sessions at 2-week intervals with either a 1064-nm picosecond laser with MLA or a 1565-nm nonablative fractional laser. Images were captured at each visit. Objective (pore number) and subjective assessments, including patient self-evaluations and quartile improvement scales, were used to evaluate the treatment efficacy. The pain levels and adverse effects were recorded at each subsequent visit. RESULTS The participants were 3 men and 22 women with enlarged facial pores. At the initial and 2-month checkups after the last treatment, the pore numbers were significantly decreased bilaterally for both lasers. The respective quartile improvement scale scores for the 1064-nm picosecond and 1565-nm fractional lasers were 2.22 ± 1.06 and 2.14 ± 1.11, while those for patient self-assessment were 3.72 ± 0.74 and 3.68 ± 0.75. The pore number, quartile improvement scale score, and patients' self-assessments did not differ significantly between the two lasers. Treatment with the 1064-nm picosecond laser better reduced pain compared with the 1565-nm nonablative fractional laser (4.11 ± 1.33 vs. 4.83 ± 1.17). The occurrence of pigmentation did not differ significantly between the lasers. CONCLUSION Both the 1064-nm picosecond laser with MLA and the 1565-nm nonablative fractional laser are viable options for treating enlarged pores, and showed comparable respective efficacies; however, the former was less likely to cause hyperpigmentation and was better tolerated.

Abstract
Facial pores are visible openings of pilosebaceous follicles, and they are one of the major factors influencing facial skin appearance. This article aims to evaluate and compare the efficacy and safety of 1565-nm non-ablative fractional laser (NAFL) and long-pulsed 1064-nm Nd:YAG laser (LPNY) in treating enlarged facial pores. All subjects were treated with NAFL on their left faces and LPNY on their right. Five treatments were administered at 2-week intervals, with one follow-up session 2 months after the final treatment. Treatment efficacy was evaluated by subjective (pore improvement and subject satisfaction ratings) assessments and objective (pore number) assessments. At each appointment, any side effects or complications were recorded to evaluate the safety of the two lasers. A total of 18 individuals participated in this study. At the 2-month follow-up, NAFL and LPNY sides had significant reduction in pores (p < 0.0001 and p < 0.0001, respectively). However, there was no statistically significant difference in the mean number of pore reductions on either side (p > 0.05). There was no significant difference in pore improvement ratings and satisfaction ratings between the two sides (p > 0.05 and p > 0.05, respectively). Both lasers showed minimal side effects. Both lasers effectively treated enlarged facial pores and were well tolerated. The side effects of the 1064-nm LPNY were less severe than those of the 1565-nm NAFL.

J Cosmet Dermatol 2020; 20:274-284. [PMID: 32548941 DOI: 10.1111/jocd.13479] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 05/03/2020] [Accepted: 05/04/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Serine is a hypoallergenic but inefficient chemical exfoliant. Serine paired with arginine (ion-paired amino acid, IPA) shows enhanced lipophilicity, skin permeation, and exfoliation efficacy. AIM This study was conducted to determine whether exfoliation using an emulsion containing IPA could reduce enlarged facial pores and improve the dermis density. METHODS IPA formation was validated by spectroscopic analysis. Enhanced permeability and exfoliation efficacy were evaluated ex vivo using porcine skin. In a clinical trial, healthy Korean women aged 20-49 years (mean age ± SD: 35.6 ± 8.6, n = 64) were evaluated, and the right and left sides of the cheeks were randomly chosen. An emulsion containing 4.0% IPA and placebo emulsion were applied to each side for 6 weeks. To evaluate pore sizes following treatment, the number of enlarged facial pores, inner skin structures from the stratum corneum to epidermal-dermal interface, and dermal density on each cheek of the participants were assessed. RESULTS IPA showed a significantly increased partition coefficient in n-octanol-water. In porcine skin, permeation of serine after 12 hour was 70% higher for the IPA than for serine alone at the same percent weight concentrations. In the clinical trial, after 6 weeks, the number of enlarged facial pores was changed by -19.317% in the IPA emulsion group (P < .001) and -2.930% in placebo emulsion group (P = .254). CONCLUSION Exfoliation with an IPA-containing emulsion reduced enlarged facial pores and increased the dermis density. IPA, effective mild exfoliator, can be used as a major ingredient for the cosmeceutical skincare products in the future.

Abstract
Background Facial wrinkles, pores, and uneven skin tone are major beauty concerns. There is differential manifestation of aging signs in different ethnic groups. In this regard, studies on Black Africans from the African continent are scarce. Objective To investigate facial wrinkles, pores, and skin tone in Black African women from Mauritius Island and elucidate the differences to Caucasian women from France. Methods Facial images were taken using the imaging system ColorFace®. Wrinkles and pores were measured by their length, depth, surface, volume, and number; for skin tone, we measured L*a*b* and calculated ITA, IWANewtone, and color homogeneity. Results We found good correlations of wrinkle and pore scores with expert ranking done on ColorFace® images for Caucasians (Spearman's rho = 0.78 and 0.72) and Black Africans (Spearman's rho = 0.86 and 0.65). Caucasians showed more advanced facial signs of aging than Black Africans. Exceptions were vertical lines on upper lip and the depth of pores which were greatest for the Black African subjects. Black Africans had higher heterogeneity scores indicative for uneven skin tone. Luminance (L*) was significantly higher in Caucasians but a* and b* values were significantly higher in the Black African subjects. ITA and IWANewtone were significantly higher for Caucasians. Conclusions The high correlation between expert ranking and wrinkle and pore measurements prove ColorFace® a valid imaging system to study skin aging. Our results show that Africans from the African continent show delayed signs of aging compared to Caucasians. Some exceptions suggest that ethnic differences in facial aging are a complex phenomenon.

Abstract
Background Over the past 10 years, monopolar radiofrequency (MRF) technology has been widely used by dermatologists as a valuable modality to effectively tighten and rejuvenate photoaged skin. It also has the benefit of a short recovery time. Objective Using an objective parameter, this study aimed to assess the efficacy and safety of MRF, which is the basic modality of radiofrequency technologies, for treatment of periorbital wrinkles in Korean patients. Methods We enrolled 70 middle-aged female patients with periorbital wrinkles for this study. Each patient underwent triple sessions of MRF treatment in the periorbital region, separated by 2-week intervals. Clinical photographs were obtained, and the areas of wrinkles were measured using a Robo Skin Analyzer CS50 (Inforward Inc., Japan) at baseline and 4 weeks after the final treatment session. Results Significant reduction in the mean area of periorbital wrinkles was detected at 1-month follow-up (80.64±28.96 mm2) compared to baseline (95.08±31.93 mm2). The improvement ratio of the wrinkle area was 15.19%. Pain during procedure seemed to be tolerable without any local anesthesia for all patients. Transient mild erythema was the only side effect reported during the study. Conclusion In conclusion, MRF could still be an attractive modality for Korean patients with periorbital wrinkles if the treatment is conducted repeatedly with sufficient energy and proper intervals.

Abstract
Skin pores (SP), as they are called by laymen, are common and benign features mostly located on the face (nose, cheeks, etc) that generate many aesthetic concerns or complaints. Despite the prevalence of skin pores, related literature is scarce. With the aim of describing the prevalence of skin pores and anatomic features among ethnic groups, a dermatoscopic instrument, using polarized lighting, coupled to a digital camera recorded the major features of skin pores (size, density, coverage) on the cheeks of 2,585 women in different countries and continents. A detection threshold of 250 μm, correlated to clinical scorings by experts, was input into a specific software to further allow for automatic counting of the SP density (N/cm2) and determination of their respective sizes in mm2. Integrating both criteria also led to establishing the relative part of the skin surface (as a percentage) that is actually covered by SP on cheeks. The results showed that the values of respective sizes, densities, and skin coverage: 1) were recorded in all studied subjects; 2) varied greatly with ethnicity; 3) plateaued with age in most cases; and 4) globally refected self-assessment by subjects, in particular those who self-declare having “enlarged pores” like Brazilian women. Inversely, Chinese women were clearly distinct from other ethnicities in having very low density and sizes. Analyzing the present results suggests that facial skin pore’s morphology as perceived by human eye less result from functional criteria of associated appendages such as sebaceous glands. To what extent skin pores may be viewed as additional criteria of a photo-altered skin is an issue to be further addressed.

Abstract
BACKGROUND Chemical peeling is becoming increasingly popular for skin rejuvenation in dermatological cosmetic medicine. However, the improvements seen with chemical peeling are often very minor, and it is difficult to conduct a quantitative assessment of pre- and post-treatment appearance. AIMS We report the pre- and postpeeling effects for facial pigment deposition using a novel computer analysis method for digital-camera-captured images. PATIENTS/METHODS Glycolic acid chemical peeling was performed a total of 5 times at 2-week intervals in 23 healthy women. We conducted a computer image analysis by utilizing Robo Skin Analyzer CS 50 and Clinical Suite 2.1 and then reviewed each parameter for the area of facial pigment deposition pre- and post-treatment. Parameters were pigmentation size and four pigmentation categories: little pigmentation and three levels of marked pigmentation (Lv1, 2, and 3) based on detection threshold. Each parameter was measured, and the total area of facial pigmentation was calculated. RESULTS The total area of little pigmentation and marked pigmentation (Lv1) was significantly reduced. On the other hand, a significant difference was not observed for the total area of marked pigmentation Lv2 and Lv3. CONCLUSION This suggests that glycolic acid chemical peeling has an effect on small facial pigment disposition or has an effect on light pigment deposition. As the Robo Skin Analyzer is useful for objectively quantifying and analyzing minor changes in facial skin, it is considered to be an effective tool for accumulating treatment evidence in the cosmetic and esthetic skin field.
