Lip darkening can occur for several reasons. One common cause is prolonged sun exposure, which leads to increased melanin production in the lips, resulting in darker pigmentation. Smoking is another significant factor, as it can cause lips to darken over time due to the toxins in cigarettes. Hormonal changes, such as those experienced during pregnancy, menopause, or the use of birth control, can also contribute to lip pigmentation issues. Additionally, harsh lip products that dry out the lips or constant lip biting can further exacerbate discoloration. IPRAD Skin & Laser Clinic offers a safe and effective way to address these causes through advanced laser treatment, which targets and breaks down excess pigmentation to reveal the natural pink color of your lips.
