Retinaldehyde cream effectively reduced facial redness (erythema) in most rosacea patients within five months. While it also improved spider veins (telangiectasia), the effect was less pronounced and took longer to appear.

Area of Science:

  • Dermatology
  • Cosmetic Science
  • Retinoid Research

Background:

  • Facial rosacea presents with vascular signs like persistent erythema and telangiectasia.
  • Retinoic acid is anecdotally suggested for mild rosacea treatment.
  • Retinaldehyde, a precursor to retinoic acid, offers a potential therapeutic option.

Purpose of the Study:

  • To evaluate the efficacy of topical retinaldehyde in patients with facial rosacea.
  • To assess the impact of retinaldehyde on erythema and telangiectasia.
  • To utilize clinical and instrumental measurements for objective assessment.

Main Methods:

  • An exploratory study involving female patients with facial rosacea.
  • Application of 0.05% retinaldehyde cream once daily for six months.

  • Monthly clinical assessments using a 4-point severity score for erythema and telangiectasia.
  • Instrumental evaluation of erythema via spectrophotometric measurement of the a* parameter.

    • Main Results:

    • Approximately 75% of patients showed clinical improvement in erythema after five months (p < 0.05).
    • Spectrophotometry revealed a significant reduction in erythema (a* parameter) by about 15% after two months (p = 0.001).
    • A clinical response in telangiectasia was observed in 46% of patients after six months, though not statistically significant.

    Conclusions:

    • Topical retinaldehyde demonstrates beneficial effects on the vascular component of rosacea.
    • Retinaldehyde is effective in reducing persistent erythema associated with rosacea.
    • Further investigation into retinaldehyde for rosacea treatment is warranted.
