Treating Dark Circles
The best way to get rid of dark circles is to prevent them in the first place. You may not be able to completely stop them from occurring, but they are much easier to treat if you look at your lifestyle and try to determine why you’re getting them. This is also a good way to improve the look of your skin overall, because anything contributing to dark circles is good for the rest of your skin.
Eat Well
The best prevention of dark circles under the eyes is to eat, drink and sleep well, reduce stress and combat fatigue. The food you eat can affect your complexion, and you need to ensure you’re getting enough vitamins and minerals. When you provide your body with the right nutrients, your complexion becomes more radiant regardless of age. Nourished skin is more plump, so the appearance of dark circles is reduced.
Inadequate antioxidants or lack of vitamins like Vitamin K, Vitamin B12 mainly causes dark circles. Vitamin deficiency is caused due to improper diet. Diet should be balanced to get rid of dark circles; you should have plenty of water, fruits, green leafy vegetables especially kale, cabbage and spinach.
Eat a whole-foods, plant-based diet, drink plenty of water, and avoid alcohol and soft drinks. Further, don’t smoke, and use a sunscreen when outside, as these tips can go a long way in preventing circles and wrinkles.
Get Enough Sleep
Inadequate sleep is the main cause for dark circles, because eyes get strained if you don’t sleep well and makeup should be removed before going to sleep. Ideal sleeping time is 7 to 9 hours which varies with different people depending on their lifestyle. Make habit of sleeping for sufficient time so that you may see some changes regarding dark circles. Drugs and alcohol are also causes for the dark circles as they affect the quality of sleep. Poor absorption of vitamins leads to the lack of sleep, because it reduces adrenal function.
Avoid Smoking
Smoking makes your blood vessels appear more prominent and darker as it causes vascular issues.
