Vitamins significantly influence skin health, contributing to hydration, collagen synthesis, and protection against oxidative damage. In topical care, vitamins are harnessed in various formulations such as creams, serums, lotions, and wash products, directly benefiting the skin's surface. These formulations enhance hydration, promote collagen biosynthesis, and provide protection against oxidative stress. Cosmetic procedures leverage vitamins in peels, mesotherapy, and postlaser treatment products, aiding skin recovery and rejuvenation. Systemic therapy involves incorporating vitamins into dietary supplements designed to combat the aging process from within. The multifaceted roles of vitamins necessitate nuanced considerations for potential side effects, contraindications, and adherence to regulatory frameworks.

Although aesthetic procedures aim to enhance appearance, dermatologists are tasked with ensuring patient safety and adhering to ethical medical practices. In certain situations, refusing treatment may represent the most appropriate clinical decision. The term persona non grata, originally used in diplomacy, serves as a useful metaphor in aesthetic dermatology to describe patients for whom cosmetic procedures may be unsuitable due to ethical, medical, or psychologic concerns. We discuss situations in which dermatologists may need to decline aesthetic procedures and highlight specific patient profiles that require caution. We examine ethical considerations, including informed consent, patient autonomy, and the physician's duty to avoid harm. Additionally, we focus on psychologic aspects, particularly unrealistic expectations, social media-driven aesthetic demands, and psychiatric comorbidities like body dysmorphic disorder. Recognizing these high-risk situations is crucial for maintaining professional integrity and minimizing complications in aesthetic practice. Finally, we review legal safeguards for patients who may not be suitable for aesthetic procedures.
