For safe and effective skin brightening, look for over-the-counter creams containing active ingredients like Vitamin C, Niacinamide, Kojic Acid, Azelaic Acid, or Alpha Arbutin. These ingredients gently target uneven skin tone and dark spots. For stronger concerns, a dermatologist may prescribe Hydroquinone, which should only be used short-term under medical supervision. Always perform a patch test on your jawline first to check for any irritation. Most importantly, apply a broad-spectrum sunscreen of SPF 30 or higher daily, as sun exposure can reverse the benefits of these treatments. I highly recommend consulting a dermatologist to find the best option for your specific skin type.
