how to get rid of dark circles under eyes

Dark circles have different causes, and the treatment depends on the type. Dark circles from pigmentation (brownish tones) respond to vitamin C serums or bleaching agents like hydroquinone, along with daily sunscreen under the eyes. Blue or purple dark circles are usually from visible blood vessels through thin under-eye skin — topical retinol creams can help thicken the skin over time, while caffeine-based eye creams temporarily constrict blood vessels to reduce appearance. For dark circles caused by hollows or deep tear troughs (shadows from bone structure), dermatologists can use injectable fillers like hyaluronic acid to smooth the area. At-home treatments like cold compresses, getting enough sleep, and staying hydrated help with puffiness and tired-looking eyes but won’t fix structural or pigmentation-based circles. source: Cleveland Clinic and Mayo Clinic
