For acne, scars, and tanning, the most effective approach is to use gentle, proven ingredients rather than fairness creams, as they safely improve skin tone over time. Look for creams or serums containing niacinamide (reduces marks and improves tone), retinol (helps fade scars and renew skin), or mild exfoliating agents like salicylic acid. Good options include Dot & Key CICA + Niacinamide Oil-Free Moisturiser for daily use, Dermatouch Salicylic Acid + Niacinamide Gel for acne control, and Minimalist Retinol Face Serum for reducing acne scars at night. Most importantly, use sunscreen every morning, as sun exposure worsens tanning and dark marks. Keep your routine simple: cleanser, treatment cream, moisturiser, and sunscreen, and avoid harsh or mixed creams without medical advice. If acne is severe or scars are deep, consult a dermatologist for stronger treatments.
