ABSTRACT

BACKGROUND: Dyspigmentation and photodamage are common concerns in patients who seek aesthetic consultation. A number of treatment modalities have been utilized to address this issue. 1927 nm thulium fiber laser is a fractionated non-ablative laser that has been shown to be safe and effective in treatment of photoaging. Topical retinoids have been used for over two decades for photoaging to promote epidermal hyperplasia and collagen synthesis and to decrease melanin production. There has been lack of data to support the combination of topical retinoids with laser treatments in the management of facial dyspigmentation and photodamage. OBJECTIVE: The primary objective of this study is to evaluate the benefits and subject satisfaction resulting from use of a 1927 nm thulium fiber laser with and without 0.05% tretinoin lotion for facial dyspigmentation and photodamage. RESULTS: Both groups showed a significant change in Investigator Assessed Overall Hyperpigmentation and Investigator Assessed Overall Photodamage over time (P<0.001). No statistically significant differences were seen between groups at any time point as measured by investigator reported and subject reported efficacy scales except for Subject Global Aesthetic Improvement Scale and Subject Satisfaction at 30 days after laser treatment, at which patients who received 0.05% tretinoin lotion reported a lower level of improvement (2.8 ± 0.86 in the treatment group vs 2 ± 0.85 in the vehicle group, P=0.009) and lower patient satisfaction when compared to the vehicle group (2.87 ± 1.55 in the treatment groups vs 1.53 ± 0.64 in the vehicle group, P=0.001). CONCLUSION: In our study, patients tolerated the combination of 1927 nm thulium fiber laser and 0.05% tretinoin lotion well. Both groups resulted in significant reduction of hyperpigmentation and photodamage. Subject satisfaction and perceived improvement were temporarily lower at 30 days only when, combining 0.05% tretinoin lotion with 1927 nm thulium fiber laser. Future studies are needed to investigate the impact on efficacy when combining laser procedures with a longer duration of use or a higher concentration of topical tretinoin.
