Filter by:A randomized controlled split-face pilot study was planned to investigate the preventive effect of tretinoin 0.05% cream on hyperpigmentation during phototherapy in patients with vitiligo.
Facial hyperpigmentation is a common skin issue that can cause embarrassment and affect the quality of life in majority of people. The investigators are conducting a research to study an efficacy and tolerability of Isobutylamido-thiazolyl-resorcinol 0.2% in lightening of the facial hyperpigmentation in comparison to vehicle intervention in 4, 8 and 12-week period. The ultimate goal is to provide the best cosmetic cream to improve the quality of life of people who suffer from facial hyperpigmentation.
Although physiologic gingival hyperpigmentation is not a pathologic condition, it is considered one of the main esthetic problems in dentistry. It was found that the attached gingiva is the most frequently pigmented intraoral tissues followed by the papillary gingiva and the alveolar mucosa
Pierre Fabre Dermo-Cosmétique has commercialized a cosmetic product (D-pigment rich texture) for treatment of hyperpigmentation. The aim of this study is to evaluate the efficacy of D-pigment after laser therapy, through its action on peri-lesional areas, in obtaining better cosmetic effect.
This is a single-center, open label pilot study. The study is comprised of 5 study visits; Screening, Baseline, and Weeks 4, 8, and 16. All subjects will receive Onexton at Baseline and be instructed to apply the gel once daily to the face. The investigators will evaluate Investigator Global Assessment of acne (IGA), total lesion count, inflammatory lesion count, non-inflammatory lesion count, Investigator Global Assessment of Post-Inflammatory Hyperpigmentation and distribution of Post-Inflammatory Hyperpigmentation, adverse events and concomitant medications.
This study will evaluate the physiopathologic characteristics of dark circles in participants with various ethnicities and Fitzpatrick Skin Types and the impact of the dark circles on the quality of life.
Vitamin C affect the melanocytes function not the number while diode laser cause melanocytes destruction. Although diode laser and vitamin C have proved their effectiveness in depigmentation in previous studies, there are no published studies compared the effect of diode laser and vitamin C on melanocytes and melanosomes clinically and histologically.
10 ml of blood from each patient will be drawn. This blood specimen will be centrifuged in a specific way to get 1 ml of platelet rich plasma (PRP). PRP will be injected into the the skin under the eyes. The treatment course consists of three sessions of PRP injections with one-month intervals between the sessions.
Post-inflammatory hyperpigmentation (PIH) is an acquired hypermelanosis that occurs after cutaneous inflammation or injury that frequently affects darker skinned populations. Previously, a model of 35% TCA-induced PIH was validated against acne induced PIH, which has value in product testing for the treatment of PIH. In this second phase of the study, the investigators would like to determine if a lower concentration of TCA-induced PIH is comparable to acne-induced PIH.
To investigate the benefit of the application of topical high potency steroid on the incidence of post inflammatory hyperpigmentation after laser treatment.
