Sleeping for 7–9 hours each night, can allow your body to repair and restore the skin. Good sleep enhances blood circulation, also lessens under-eye darkening and keeps the skin firm and healthy.
Drink more water
Dehydration dries out your skin and makes it lose volume, but using cucumber slices can help hydrate the area. When your body gets enough water every day, it helps your skin get firmer and makes the skin under the eyes less sunken and dull.
Protect your skin from the sun
Your under-eye skin is delicate and susceptible to UV rays. That’s because too much sun breaks down collagen, which makes the skin saggy and hollow. Wearing sunscreen and sunglasses protects the area, too, and helps keep its structure.
Use the right eye cream.
Eye creams with hyaluronic acid, peptides or caffeine can bring added hydration and firmness to the eye area, and are a great way to fix sunken eyes. They build circulation while also preventing the dryness that can create hollows.
Eat a healthy, balanced diet
The vitamins in fruits, vegetables, and foods with vitamins A, C, E, and K help support collagen production and skin repair going forward. While this keeps your under-eye area nicely hydrated and less likely to sink in or darken.
Limit alcohol and caffeine
Too much can dry out your skin and make your eyes look tired.
