Filter by:CS5_2 study aims to evaluate the tolerance of 4 different conditions of cryotherapy treatments applied on dorsal post-inflammatory hyperpigmentation (PIH) spots. This study is a proof of concept, designed to be interventional, monocentric, randomized and double blind. The study will evaluate 4 prototypes : (814A-v1), (814B-v1), (814C-v1) and (814D-v1).
This open-label, multi-center clinical trial was conducted to evaluate the dual skincare regimen of vitamin C serum and moisturizing sunscreen SPF 45 to improve facial hyperpigmentation and photodamage after 12 weeks of twice daily use in healthy female subjects between 35 - 60 years old. A total of 33 subjects completed study participation.
The purpose of this study is to evaluate the efficacy and safety of Trifarotene 50 microgram per gram (mcg/g) cream compared to its vehicle cream in the treatment of moderate acne vulgaris with risk of acne-induced post inflammatory hyperpigmentation (PIH) after 24 weeks of treatment in facial acne participants
This pilot study will expand knowledge and application needling using the Straberi device for the improvement of Postinflammatory Hyperpigmentation (PIH) caused by acne.
Subjects were randomly assigned to groups for treatment with either an EGF-containing ointment (the study group) or the vehicle alone (petrolatum; the control group). The EGF ointment included recombinant human EGF (1 μg/g). Random numbers used for assignment to groups were provided by the randomization function of SAS. The subjects received one session of laser treatment with a Q-switched (QS) 532-nm Nd:yttrium aluminum garnet (YAG) laser of their solar lentigines after enrollment. . The end point of laser treatment for lentigines was immediate whitening. The subjects then applied the EGF ointment or vehicle twice daily (morning and evening) to the lesion for 4 weeks after laser treatment.
Both vitamin C 20% and tranexamic acid 5mg/ml combined with microneedling were used for treatment of periorbital hyperpigmentation in a comparative pattern and both resulted in significant improvement of periorbital hyperpigmentation by dermoscopic and clinical evaluation with no statistically significant difference between them in addition to improvement of patients' visual analogue score (VAS) and dermatology life quality index (DLQI).
This randomized clinical trial evaluated the recurrence rates of physiological gingival pigments during 24 months follow-up and the patient perceptions after the ablative depigmentation using two laser wavelengths; Diode 940 nm and Er,Cr:YSGG 2780 nm.
Currently, there are limited prevention or treatments available for dyschromia in burn hypertrophic scars (HTSs). The limited available techniques involve transferring melanocytes from unaffected areas to the scar to adjust pigment. These techniques involve the creation of a donor site and do not utilize the cells that may already be present in scars. This study aims to confirm melanocyte presence in regions of hypo- and hyper- pigmented HTS. If melanocytes can be found in regions of hypopigmentation, these scars may be able to be treated in the future by pigmentation stimulators without the need for surgery. Additionally, if pigmentation specific molecules of interest can be found to be up-regulated in hyperpigmented scar, these may be able to be altered by a pharmacotherapy.
Recent research has reported that the maple leaf extract exhibits anti-aging effects by inhibiting elastase activity, thereby preventing the breakdown of elastin and interfering with the formation of wrinkles. Red maple leaf extract contains phenolic compounds known as glucitol-core-containing gallotannins (GCGs) which help reduce the appearance of wrinkles and may decrease skin inflammation, dark spots and pigmentation. The objective of this study is to examine the effects of topical Maplifa on the cosmetic appearance of facial lines, redness and skin tone.
Periorbital hyperpigmentation (POH) is a common condition in dermatology practice. Periorbital hyperpigmentation is defined as bilateral, round, homogeneous pigmented macules.The etiology of POH is multifactorial including genetic and enviromental factors. Many treatment options are avaiblabe with variable efficacy and safety in different patients. Therefore, the investigator's study aims to evaluate the efficacy and safety of combined microneedling with topical Glutathione versus Carboxy Therapy in treatment of patients with periorbital hyperpigmentation.
