Surfactants in cleaners dissolve hydrophobic substances in an aqueousphase, allowing them to move away from the skin surface. The negative effect of surfactants on the skinbarrier can be reduced by changing the solution properties. We thought to do this research in order tomaster the product contents, to identify the products with the highest user satisfaction, to identifyproducts with potentially harmful contents or inappropriate contents, so that we could easily choose theright product and direct the patients correctly. Material and Method: It was planned to select 10 facecleansing products sold on the most popular website selling online dermo-cosmetic products in ourcountry. The criteria for having the most internet traffic were searched for in the selection of the website.We used to classify the specified basic ingredients according to their chemical properties. The reviewsmade for each of the 10 products were examined from the most recent date to the old date. Results: Wedetected 87 different chemicals in 10 different products. The fake product notification was particularlyin expensive products. No correlation was detected between the number of surfactants in the productswith the positive effects such as cleansing effect, the effect of reducing and increasing acne, dryness,redness, burning and smoothing, and softening. (p>0.05) There was a negative correlation between thecleansing effect of the products and the improvement and worsening of acne. (p<0.05, p<0.001,respectively) Conclusion: A good face cleaning product does not need to contain numerous chemicalsand surfactants. It should be kept in mind that especially expensive products may be counterfeit, and theproducts should be questioned by the local product detection system from the barcode number.Publication Metadata only Serum vitamin B12, ferritin, and vitamin D levels in patients with seborrheic dermatitis: A case-control study(2022-10-01T00:00:00Z) Guder, Semih; Güder, Hüsna; GUDER, SEMİHPublication Metadata only Prurigo pigmentosalı beş olgunun demografik, klinik ve etyolojik açıdan incelenmesi(2021-06-17T00:00:00Z) Guder, Semih; GUDER, SEMİHPublication Metadata only Efficacy of Fractional Microneedle Radiofrequency Application in Abdominal Wrinkles and Sagging: Case Report(2020-08-01T00:00:00Z) Guder, Semih; GUDER, SEMİHPublication Metadata only Prurigo Pigmentosa: A Report of Two Patients in Possible Association with Essential Fatty Acid Deficiency(2021-12-01T00:00:00Z) Guder, Semih; Güder, Hüsna; GUDER, SEMİHPrurigo pigmentosa is a rarely seen dermatosis with pruritic reticular erythematous lesions, generally located in the midline of the trunk. Its etiology has not yet been fully understood. The lesions were clinically compatible with prurigo pigmentosa in two male patients aged 19 and 22, who were admitted to our outpatient clinic with brown-red itchy spots on their bodies, and both were on a low-carbohydrate and low-fat diet. They were completely cured by dietary change and tetracycline treatment. A low-carbohydrate diet or ketosis is commonly seen with prurigo pigmentosa, and the disease may be regressed by diet changes. Ketone bodies are accused in the etiology of prurigo pigmentosa, but the disease is not seen in each patient with ketosis. Low carbohydrate intake or ketosis affects fatty acid metabolism. We believe that changes in fatty acid amounts or composition in the skin may probably play a role in the etiopathogenesis of prurigo pigmentosa.Publication Metadata only Ortopedik cerrahide cerrahi alan infeksiyonu risk faktörleri(2020-11-01T00:00:00Z) Guder, Semih; GUDER, SEMİHPublication Metadata only Deri ve Travma(2021-12-01T00:00:00Z) Guder, Semih; GUDER, SEMİHeri esnek bir organ olup travmaya bir seviyeye kadar karşı koyabilir. Sürtünme, basınç, gerilme, sıcak, soğuk ve kesikler yoluyla deride oluşan mekanik travma cildin bütünlüğünü ve fonksiyonlarını etkileyebilmektedir. Deriye uygulanan mekanik travma, kornifiye tabakadan subkutan adipoz dokuya kadar derinin tüm seviyelerini etkileyebilir. Travmaya adaptasyon süresi cildin tepkisini belirler. Yavaşça artan basınç veya sürtünme hiperkeratoz, likenifikasyon ve nasırlara (kallus ve korn) neden olurken, ani sürtünme ve basınç büllere neden olabilir. Travmanın etkileri nem, terleme, yaş, cinsiyet, beslenme durumu, enfeksiyon, genetik ve ırksal faktörler tarafından değiştirilir. Bu bölümde fiziksel travmaya bağlı gelişen deri bulguları, hastalıkları ve bunlara yaklaşım ele alınacaktır. Yaralanmalar, asit-alkali, termal ve radyasyona bağlı yanıklar bu bölümün dışında tutulmuştur. Ayrıca saç ve mukoza hastalıklarına da yer verilmemiştir. Fiziksel (mekanik) travma ile ilişkili deri hastalıkları aşağıdaki gibi sınıflandırılmıştır.- Friksiyonel deri hastalıkları- Kronik kaşıntıya bağlı gelişen hastalıklar- Basınca bağlı gelişenler- Termal (ısı – soğuk) etkilere bağlı gelişenler- Vibrasyon ile oluşanlar- Künt travmaya sekonder gelişenler- Kişinin kendi yaptığı fiziksel travmaya bağlı gelişen psikokutan derihastalıkları- Travma ile kötüleşen deri hastalıkları- Koebnerize deri hastalıklarıPublication Open Access Spinal Pathologies in Patients with Notalgia Paresthetica and Positive Effect of Strengthening Exercises on Itch Relief(2021-07-01T00:00:00Z) Guder, Semih; Güder, Hüsna; GUDER, SEMİH
