Comparative Effectiveness of Clindamycin-Retinoid, Clindamycin-Retinoid-Dexamethasone, and 10% SM-hUCMSC Secretome Gel in the Improvement of Mild-to-Moderate Acne Vulgaris

Starting soon · Phase 1/Phase 2

Conditions studied: Acne Vulgaris

In brief

The goal of this clinical trial is to etermine and compare the effectiveness of three therapeutic regimens for mild to moderate acne vulgaris, such as, clindamycin-retinoid combination, clindamycin-retinoid-dexamethasone combination, and sekretome SM-hUCMSC 10% gel. The main questions it aims to answer are : * Is there a change in the number of inflammatory lesions (papules, pustules, nodules) and non-inflammatory lesions (open and closed comedones) before and after treatment in each treatment group? * Is there a difference in the reduction of acne vulgaris severity scores among the three treatment groups? * Are there differences in the rate of clinical improvement (time required to achieve a certain reduction in lesion count or severity score) among the treatment groups? * What are the incidence and characteristics of local adverse effects (erythema, burning sensation, skin dryness, irritation, hypo-/hyperpigmentation, and others) in each treatment group? * Are there differences in the impact of each therapeutic regimen on the risk of acne scar formation and improvement in skin quality (texture, elasticity, and color homogeneity)? * Does secretome gel demonstrate sufficient clinical potential and urgency as a safer and more prospective topical therapeutic alternative for acne vulgaris compared with retinol-clindamycin and retinol-clindamycin-dexamethasone 0.1% combinations? Participants will be allocated into three groups using simple block randomization. * Group A will receive a combination of clindamycin and a retinoid, applied thinly to the entire facial area once daily at night. * Group B will receive a combination of clindamycin, a retinoid, and dexamethasone, with the same method of application as Group A. * Group C will receive 10% SM-hUCMSC secretome gel, applied thinly to acne-affected areas twice daily (morning and night).
