Introduction

Minéral 89 (M89), comprised of 89% Vichy mineralizing water and hyaluronic acid, has been formulated to help strengthen and restore skin barrier.

Aim

Assess tolerance and efficacy of M89 in post-esthetic procedures and dry skin-related facial dermatoses.

Method

Adults post-esthetic procedure or presenting with inflammatory dermatoses (47 subjects; mean age 40.9 ± 13.2 years; any Fitzpatrick or skin phototype), applied M89 for 4 weeks, once or twice daily, as an adjuvant treatment. Information on clinical signs and subject-reported symptoms, skin characteristics, tolerance, and subject and investigator satisfaction were collected.

Results

Following 4 weeks of M89 use, significant decreases with complete resolution of erythema (27.6%), desquamation (29.8%), irritation (32%), and skin dehydration (35.8%), as compared to baseline signs and symptoms, were observed. Overall grading improvements for erythema (84.8%; p < 0.001), desquamation (91.7%; %; p < 0.003), irritation (91.7%; %; p < 0.015), and skin hydration (46.2%; p < 0.015) were noted. There was no significant improvement in papules and pustules. Evaluation of subjective signs demonstrated significant decreases in skin sensations such as burning (-73%; p < 0.0001), itching (-71%; p < 0.0001), stinging-tingling (-66.7%; p < 0.0001), as well as in skin dryness (-60%; p < 0.0001). M89 texture was rated very pleasant by 90% of patients. Investigators assessed M89 tolerance to be either good or very good (93%), and satisfactory or highly satisfactory impact on patient's skin (91.5%).

Conclusion

M89 is a highly tolerable adjuvant treatment that significantly improved clinical signs and symptoms related to a compromised skin barrier in various facial dermatoses and post-aesthetic procedures.
