Dark circles or discoloration under the eyes can be caused by several factors, including heredity, allergies, sleep deprivation, dehydration, thinning skin due to aging, and sun exposure. Treatments vary based on the underlying cause. If fillers didn't provide the desired results, here are a few other options you could consider: 1. Topical Creams: Some creams and serums contain ingredients like retinol, vitamin C, and caffeine that can help to lighten the under-eye area. These are usually applied daily. 2. Laser Therapy: Laser treatment can reduce the appearance of blood vessels and pigment that contribute to dark circles. The procedure stimulates collagen production, which can thicken the skin and reduce the visibility of blood vessels and pigment. 3. Chemical Peels: A light chemical peel can help to lighten the under-eye area and stimulate new skin growth. 4. Microneedling: This treatment uses tiny needles to create small wounds in the skin, which stimulates collagen production and can help to reduce dark circles. 5. Intense Pulsed Light (IPL) Treatment: This is a type of light therapy that can target and break down pigment, reducing the appearance of dark circles. 6. Surgery: In some cases, a surgical procedure known as blepharoplasty may be considered. It can help to remove excess fat and skin in the under-eye area, reducing the appearance of dark circles. Remember, it's important to consult with a dermatologist or a cosmetic surgeon to discuss these options and decide what's best for you based on your specific needs and health history. They can also help you understand potential risks and benefits of each procedure.
