Ramadan fasting alters circadian cortisol secretion patterns and may influence insulin sensitivity and glucose metabolism. Changes in sleep duration and meal timing can contribute to transient hormonal imbalance. In some individuals, these shifts may exacerbate inflammatory skin conditions such as: • Acne vulgaris • Rosacea • Seborrheic dermatitis • Melasma Increased late-night sugar consumption may further worsen acne-prone skin due to glycemic spikes and inflammatory cytokine activation. When planning aesthetic procedures for patients with active inflammatory dermatoses, clinicians should evaluate disease stability and avoid aggressive interventions during flare-ups.
