Filter by:The objective of this study is to assess and compare the efficacy of tranexamic acid intradermal microinjection alone versus its combination with low power fractional CO2 laser in a sequential pattern. In all participants one half of the face will be randomly assigned to low power fractional CO2 laser while other side to Tranexamic acid intradermal microinjections on the 1st session. This split face session will be repeated every six weeks for 3 sessions. In addition, Tranexamic acid intradermal microinjections will be applied for full face at the 2nd and 4th week of each split face session. The response will be evaluated by the Melanin and erythema Indices which will be measured using reflectance spectrophotometer, Dermoscopy and photography before starting the study, two and four weeks after the last session. The sessions will take 4 months for each patient and another one month free of sessions for follow up.
Oxidative stress has been reported to play a role in melasma pathophysiology. The objective of the study is to compare oral superoxide dismutase (GLISODin) to placebo, in combination to sunscreen to decrease melasma severity.
Melasma is a fairly common condition resulting in hyperpigmented macules on the face. Melasma is difficult to treat and has a significant negative impact on the patient's quality of life. Melasma is worsen when exposed to high energy visible light (blue and violet light) of the solar spectrum. Blue light emitted by LED screens from computers, tablets, televisions and even mobile phones is currently suspected (via media channels) to induce harmful effects on the skin, including pigmentation and photoaging. These screens, however, emit much lower irradiances than those of the solar spectrum, and the probability that these irradiances impact the skin is very low. The objective of the study is to assess the effect of blue light emitted by computer/television screens on the intensity of melasma pigmentation. To do this, it is proposed to use maximized conditions that could be encountered in normal daily life, namely a simulation of blue light exposure (420-490nm) at 20 cm from a laptop LED screen, 8 hours a day for 5 days. Since it is not proposed to expose a person for 8 hours a day, a solar simulator with appropriate filters will be used to emit a spectrum of between 420 and 490 nm with a compatible intensity for an acceptable duration of exposure (around 30 minutes a day). Twelve patients will be included in the study and exposed on a half-face from Day1 to Day5. The other half-face will serve as unexposed control. The effect of blue light on the melasma lesions will be assessed from Day 1 to Day 6 using chromametry and a modified MASI on standardized photographs. A final evaluation visit will be performed at Day 15.
- All participants will be divided into 2 groups : Group A & Group B. - Group A will be subjected to 3 consecutive sessions of Q-switched 1,064 nm Nd: YAG laser to one side of the face & fractional co2 laser to the other side of the face with one month interval between sessions. - Group B will be subjected also to 3 consecutive sessions of Q-switched 1,064 nm Nd: YAG laser to one side of the face & an additional fractional co2 laser to the other side of the face using the above mentioned parameters with one month interval between sessions. - Response to treatment will be assessed using the Melanin Index (MI) score, Melasma Area and Severity Index (MASI) score, spectrophotometer ( Derma catch, colorix, Neuchatel, Switzerland ) and a subjective self-assessment method.
Participants with face melasma will receive 4 Melanostop peel treatments containing 20% azelaic acid, 10% resorcinol and 6% phytic acid. Peels will be performed at 2-week interval. They will also receive a facial tonic and cream for at home use, containing brightening ingredients: vitamin C, niacinamide, alpha arbutin, kojic acid. They will also receive sunscreen protection cream with SPF 50, protecting against UVA, UVB, HEV and IR. Products for at home use will be used twice a day, every day. Measurements will be made at baseline, on the day of the forth peel treatment and 4 weeks after the last peel. Measured parameters will be: mMASI score, VisioFace photography analysis, melasma area measurements, and melanin index, ΔE, CIELab colour measurements with Cortex SkinLab Combo (Cortex Technology Asp, Denmark).
This study assess the effectiveness of oral tranexamic acid in combination with hydroquinone cream in the treatment of melasma.
Tranexamic acid and 1927 diode laser non-ablative fractionated laser for the treatment of Melasma.
The application of Platelet Rich Plasma (PRP) on three occasions with an interval of 15 days between each one, is related to a decrease in the intensity of the spots and improvement in the quality of the skin of patients with melasma.
Tranexamic acid has been used for treating melasma due to its effect on decreasing the activity of tyrosinase and melanogenesis. This 3-arm clinical trial will asess the efficacy and safety of oral and topical tranexamic acid as monotherapy compared with topical hydroquinone for 12 weeks in adults with melasma. The primary outcome will be the percentage of reduction at 12-week period of mMASI and melanin index. The incidence of adverse effects will be reported at weeks 4, 8 and 12.
Single center, Prospective, Open Label with Split-face Study Design. Face sides will be randomized to receive either 1064nm alone or 1064nm & 585nm combination treatment. Each subject will receive up to 3 treatments at monthly intervals (±4 days). Follow-up visits will take place at 1, 3, and 6 months following the last treatment.
