Hi thanxs for posting your question on healthcaremagic. Firstly don t panic. Dark circles can be due to various reasons.So lets rule out that first. -Pigmentation irregularities. These can cause darker circles under the eyes. -Sun exposure. This can increase melanin production. -Thinning from age. Aging thins the skin, making veins and vessels more obvious as your fat and collagen depletes over time. -Heredity. Establish whether or not this condition runs in your family, as under-eye dark circles are believed to frequently be hereditary. This doesn’t mean that you can’t do anything about the conditions, but you should be prepared for minimal success when trying to get rid of them. -Any allergies or nasal congestion. -excessive stress,lack of proper sleep. -nutritional deficiency of vit B12,VIT K. Hope it will help you to rule out the cause. My advice would be,you can try an eye cream containing vit k and retinol,these two ingredients reduce puffiness and discoloration significantly. Long-term daily use seems to have the greatest effect. You can visit a dermatologist if the condition persists. Hope it helped. Regards, Dr neha.
