Melasma is a common pigmentation disorder among young and middle-aged women, characterized by symmetrical brown-black patches on the face. It is related to genetics, ultraviolet radiation, endocrine factors and inflammation, and can lead to psychological problems and affect quality of life. Current treatments such as hydroquinone stimulation, laser therapy, and oral tranexamic acid have a high recurrence rate and poor compliance. The new gel formulation, which combines tranexamic acid (to inhibit tyrosinase), aloe polysaccharides (anti-inflammatory and repair), and lauric azon (promotes penetration), is expected to enhance efficacy and reduce side effects. This study aims to explore its clinical efficacy and synergistic mechanism, providing new strategies for the treatment of Melasma.
None
Patients with contraindications to melatonin, including pregnancy, breastfeeding, autoimmune disorders, bleeding disorders, and diabetes, or contraindications to tranexamic acid, including thromboembolic events, history of thrombosis, renal impairment, and pregnancy or breastfeeding.
Single group
Ligustrazine - tranexamic acid - aloe polysaccharide composite gel
Combination productClinical efficacy and mechanism study of laurel nitrate - tranexamic acid - aloe polysaccharide composite gel in the treatment of chloasma
Total participants are 10
Ten patients applied the composite hydrogel for 12 weeks. The MASI score was calculated at the 1st, 6th, and 12th weeks respectively to assess the improvement. A score lower than 10 was classified as mild, 11-20 as moderate, and over 20 as severe melasma. A 25% improvement in the MASI score would be considered the threshold for effective treatment.
