Hello and welcome to healthcaremagic I have gone through your concern and i have understood it. Dark circles can be quite difficult to treat. Melalite -XL cream should never be used for dark circles because it is not meant for dark circles and moreover it can cause irritation and further thinning of the already thin skin around the eye. Hereditary seems to play a significant role. In allergy prone individuals, a condition or state of atopy exists & these atopic individuals more often than not manifest with dark circles under the eyes. It also depends a lot on your lifestyle pattern- diet, sleep, computer / TV use and stress. Stressors/ Strain due to working for long hours on computers & lack of sleep play a major role too. Dark circles due to thin under eye skin, the thin skin makes the blood vessels under the skin very prominent and hence this appears dark. You could benefit from using a cream containing Vitamin K and Retinol( EGA cream). Use it once a day for at least 3 months to notice a difference. Another important cause of undereye dark circles is Iron deficiency Anemia. As can be judged from some of the reasons cited, good hydration, regular 6-8 hours of sleep, addressing stressors and a multivitamin and Iron supplement by themselves will go a long way in correcting this issue. Skin lightening cream containing glycolic acid, kojic acid, Vit C can be helpful in reducing the appearance of dark circles. Glycolic acid and Arginine peels are the two commonly used peels by dermatologists for undereye dark circles. You can try a few peeling sessions (6-8 sessions). regards
