Dr Ramon Grimalt, lecturer in dermatology at the Faculty of Medicine and Health Sciences, and Vicente Cisneros, a sixth-year student on the Bachelor’s Degree in Medicine, have published the scientific article “Dual topical therapy: the future of stretch marks?”, which reviews the most effective topical treatments for stretch marks.

Stretch marks are linear scars that appear as a result of mechanical stretching of the dermal tissue. They are a very common condition that primarily affects girls during puberty and, increasingly, boys as well, owing to emerging aesthetic trends in bodybuilding. Beyond their dermatological impact, stretch marks can cause significant psychological discomfort, particularly during life stages characterised by hormonal changes. To determine the most effective topical therapies for this condition, the authors analysed the available scientific evidence on topical treatments according to the evolutionary phase of the stretch marks.

They conclude that tretinoin is the most effective treatment in the early phases, whereas in more advanced stages it is recommended to combine it with 20% glycolic acid to improve the clinical appearance of the skin and reduce the width of the lesions.

The study also highlights the importance of preventive medicine, particularly during periods of hormonal change, and emphasises the need for a comprehensive approach that considers not only the dermatological aspects but also the impact of stretch marks on patients’ mental wellbeing.

For Vicente Cisneros, collaborating with Dr Grimalt has provided an opportunity to gain first-hand experience in clinical research and high-level scientific communication.  “Taking part in a review published in an international journal has allowed me to consolidate my vocation for medicine and explore a speciality such as dermatology before completing my degree,” he explains.
