Efficacy and Tolerability of a Double-Conjugated Retinoid and Alpha Hydroxy Acid Cream in Subjects With Mild to
Background:
Topical retinoids influence the rate of cellular turnover and improve skin clarity and photoaged skin. Consequent cutaneous irritation reduces adherence resulting in suboptimal outcomes. A formulation comprised of a double-conjugated molecule containing a retinoid and an alpha hydroxy acid (AHA) has been purposefully developed for individuals with blemish-prone skin.
Design And Methods:
A 12-week study conducted in subjects with mild/moderate blemish-prone skin evaluated skin clarity utilizing the Investigators Global Assessment Scale (0-Clear to 4-Severe). Changes in the appearance of pores were evaluated using a 6-point scale (0-None to 5-Severe). Adverse Events (AEs) and subject satisfaction were captured. A secondary analysis evaluated visible, quantitative changes in pores.
Results:
Twenty subjects enrolled; 19 subjects completed the study. Mean percent improvements in appearance from baseline in skin clarity were demonstrated at weeks 4 (43%; P<.0001), 8 (48%; P<.0001) and 12 (50%; P<.0001). Mean percent visible improvements from baseline in pores were observed at 4, 8, and 12 weeks (33% [P<.0001]; 21% [P=.04] and 25% [P=.0006], respectively). AEs were mild and transient. By 8 weeks, all subjects reported improvement in overall appearance and that their skin was healthier looking. Secondary quantitative analysis (n=6) demonstrated an 18% mean improvement in the appearance of pores from baseline at week 12.
Conclusions:
A double-conjugated retinoid/AHA cream specifically developed for individuals with blemish-prone skin demonstrated early improvements in the appearance of skin clarity and pores over 12 weeks. AEs were mild and transient. Subjects reported high levels of satisfaction in the overall appearance and quality of skin. J Drugs Dermatol. 2022;21(1):54-59. doi:10.36849/JDD.6415.
