To treat dark circles, the best topical treatment depends on the cause. For hyperpigmentation, look for eye creams containing Vitamin C, Kojic Acid, Niacinamide, or Retinol, which help brighten the skin. If dark circles are due to tiredness or visible blood vessels, creams with Caffeine (to constrict vessels) and Hyaluronic Acid (to plump the skin and reduce shadows) are highly effective. Always apply sunscreen daily to protect the delicate eye area. Additionally, prioritise 7-8 hours of sleep and good hydration. If these over-the-counter options don't work, a dermatologist can recommend stronger treatments like chemical peels or fillers.
