Detailed answer

Toners are primarily used to balance the pH of the skin, remove any residues left after cleansing, and prepare the skin for moisturizers or serums. While toners can improve overall skin health, they do not have specific properties to target dark circles. Dark circles are commonly caused by factors such as genetics, thinning skin, blood vessels showing through the skin, or pigmentation issues. To address dark circles, it is recommended to use products specifically formulated to target this concern, such as eye creams containing ingredients like vitamin C, retinol, niacinamide, or peptides. Additionally, lifestyle changes, including getting enough sleep, managing allergies or sinus issues, and protecting the delicate under-eye area from sun exposure, can also help reduce the appearance of dark circles.
