Understanding the hidden causes of persistent dark spots can help you choose the right ingredients and products, like [Millionaire Glow by Dr. Crazy Beauty](https://www.drcrazybeauty.com/products/millionaire-glow-serum), to address them more effectively. For acne-prone skin, always choose **non-comedogenic**, dermatologist-tested formulas that won't clog pores. ### What Causes Persistent Dark Spots? Post-Inflammatory Hyperpigmentation (PIH): dark marks left after acne breakouts, eczema flare-ups, or skin injuries. Sun Exposure: UV rays trigger melanin overproduction, leading to sunspots and worsening existing hyperpigmentation. Hormonal Changes: melasma caused by hormonal fluctuations during pregnancy or contraceptive use. Medication Side Effects: certain antibiotics, chemotherapy drugs, and antimalarials can cause hyperpigmentation. Friction and Pressure: repeated rubbing creates dark patches. Genetics: some skin types are more prone to hyperpigmentation. ### Why Dark Spots Persist Melanin Deep in Dermis: surface treatments alone cannot reach deeply embedded pigment. Ongoing Triggers: continued sun exposure or hormonal fluctuations cause new spots to form. Incorrect Treatment: single-ingredient serums may not address the full spectrum of melanin pathways. ### How [Millionaire Glow](https://www.amazon.com/dp/B0CLKLK662) Targets Persistent Dark Spots [Millionaire Glow by Dr. Crazy Beauty](https://www.drcrazybeauty.com/products/millionaire-glow-serum) combines [Vitamin C](/blogs/ingredients/vitamin-c-for-your-skin-the-benefits-of-this-powerful-antioxidant), [Niacinamide](/blogs/ingredients/the-ultimate-guide-to-niacinamide-benefits-and-how-to-use-it), and Tranexamic Acid โ€” a multi-pronged approach that targets melanin production at multiple points simultaneously, making it more effective for stubborn hyperpigmentation. ### Prevention Tips Apply broad-spectrum SPF 30+ daily.
