Acne flare-ups during exams are very common, especially when stress levels rise and sleep schedules get disturbed. This video explains how stress can worsen acne by increasing cortisol, a hormone that stimulates oil glands to produce more sebum. Extra oil can clog pores and create an ideal environment for acne-causing bacteria, leading to more pimples, inflammation, and slower healing. Stress may also weaken the skin barrier, making breakouts feel more stubborn. For stress-related acne, a simple routine works best: use a gentle cleanser, choose non-comedogenic products, and consider ingredients like niacinamide for oil control, salicylic acid for clogged pores, and benzoyl peroxide for acne-causing bacteria. Managing stress is just as important as treating the skin. Deep breathing, yoga, better sleep, hydration, and regular breaks can support clearer skin. If acne remains painful, severe, or persistent, a dermatologist can suggest stronger treatment options.
