Aging of upper arm skin, induced by intrinsic and extrinsic factors, often results in a loss of contour, elasticity, and firmness, and an increase in laxity, crepiness, roughness, and photodamage. A topical body firming moisturizer (TBFM) was developed to target all aspects of skin aging.
The aim of this study was to evaluate the efficacy and tolerability of the TBFM for upper arm firming and rejuvenation.
Forty female subjects, 40 to 60 years old, Fitzpatrick skin type II to V, with mild to moderate laxity, crepiness, and photodamage on the upper arms, were recruited into the study, 10 of whom were selected for biopsy analysis. Subjects were randomly allocated to apply the TBFM and placebo moisturizer on the assigned arms twice daily for 12 weeks. At each visit, efficacy and tolerability evaluation, self-assessment, and standardized clinical photography were performed. Ultrasound measurements were performed at baseline, week 8 and week 12.
Efficacy evaluation by a clinical grader and bioinstrumentation analysis showed the TBFM improved all skin parameters of the aged upper arm while outperforming the placebo moisturizer after 12 weeks. Clinical photography showed the test product toned and firmed the skin. The TBFM was well tolerated and well perceived by the subjects. Ultrasound images indicated an improvement in skin density and skin structure at week 12.
This clinical trial indicates that the TBFM was well tolerated and was effective in improving crepey, lax, and photodamaged skin of the upper arms after 12 weeks of treatment twice daily.
