Do you trust scientific evidence regarding the use of dietary supplements for treating acne?
Recent dermatological research presented in Carlsbad offers evidence that isotretinoin use does not affect adult height or restrict the use of laser skin therapies. These findings provide clarity for patients and families navigating acne treatment decisions.
Why it matters
Patients and parents frequently express concerns about whether acne medication impacts bone growth or limits cosmetic procedure options. Clarifying these safety profiles can help families make more informed decisions about long-term treatment plans with their clinicians.
A 2026 study tracking military service members found no clinically significant difference in adult height between isotretinoin users and nonusers. Furthermore, an international consensus panel reported 82% agreement that energy-based devices can be safely utilized during treatment.
The players
Dr. Carol Cheng
A researcher at the University of California, Los Angeles, who presented findings on dermatological treatments.
American Society for Dermatologic Surgery
A professional medical organization that established task forces to evaluate laser therapy safety.
The details
Clinical practice suggests continuing medication for two months after skin clearance to reach a higher cumulative dosage, which a 2025 study linked to a lower risk for relapse. Experts have also determined there is insufficient evidence to support delaying non-ablative laser therapy for those on treatment. While some acne patients consider supplements, evidence for zinc is inconsistent and linked to gastrointestinal side effects, whereas other options like green tea extract require further vetting.
Timeline
2001-2015: Danish study tracked military recruits for height data.
2017: Task force evaluated non-ablative laser therapy delays.
2022: Report published on energy-based devices and isotretinoin.
2023: Systematic review of acne supplements published.
2025: Study linked cumulative isotretinoin dosage to relapse risk.
Health Landscape
This research builds upon the standards established by the 2022 international consensus panel on energy-based devices regarding clinical safety. It shifts the focus from historical caution to evidence-based management of acne treatment and its related cosmetic interventions.
If you are concerned about side effects or acne relapse, consider discussing cumulative dosage strategies with your dermatologist. Be sure to ask your provider if non-ablative laser therapies are appropriate for your specific skin goals during your course of treatment.
The takeaway
Current research suggests that common concerns regarding bone growth and laser therapy safety during acne treatment are largely unsupported by clinical evidence. If you are pursuing long-term care, ask your doctor about the recommended two-month post-clearance extension to minimize potential relapse.
