To safely address uneven skin tone or hyperpigmentation, look for over-the-counter products containing active ingredients like Vitamin C, Niacinamide, Kojic acid, Azelaic acid, or Glycolic acid. For more pronounced dark spots, prescription-strength ingredients like Hydroquinone or retinoids can be highly effective under medical supervision. Crucially, apply a broad-spectrum sunscreen (SPF 30 or higher) daily, as sun exposure triggers melanin production and reverses progress. Please avoid unregulated creams containing strong steroids, which can damage the skin. I highly recommend consulting a dermatologist to design a safe, tailored regimen for your skin type.
