How to Rejuvenate Your Skin Naturally?
Eat more essential fatty acids (EFA).
A diet rich in essential fatty acids can help prevent dry skin and signs of aging. EFAs are vital fats that our bodies need to function. Unfortunately, we cannot produce EFAs ourselves, which means we have to get them from our diet. Foods containing essential fatty acids can make your skin more hydrated and supple, reduce inflammation caused by sun exposure, and prevent premature skin thinning.  Some foods that contain essential fatty acids are rich in:
green leafy vegetables
Eat more fruits and vegetables.
Fruits and vegetables are rich in vitamins and antioxidants that are good for the skin. Vitamins C, E and D are important for skin health, and antioxidants help protect skin from sun damage. A healthy diet rich in vitamins and antioxidants can help prevent signs of skin aging.  One of the best ways to get more vitamins and antioxidants is to eat more fruits and vegetables.  Eat a little less every day. 1-2 cups of fruit and 2-3 cups of vegetables. Some of the best antioxidant-rich options include: 
Berries such as blueberries, raspberries, blackberries and strawberries.
red and green peppers
Take collagen supplements.
Collagen supplements can help reduce the signs of skin aging. There are many supplements with dubious claims that they can slow and reverse aging, but one supplement that may be effective is collagen. Although this research is preliminary, research suggests that collagen supplements can improve skin elasticity and hydration.  If you’re looking for a really effective skin-improving supplement, check out Collagen.
Be sure to speak with your doctor before starting any new supplements.
You can find collagen supplements online and at most vitamin and health food stores.
Follow the directions on the supplement to make sure you’re getting enough every day.
Try a facial massage.
Regular facial massage can reduce swelling and make the skin firmer. The idea behind a facial massage is that it improves facial drainage (making your face less puffy) and increases blood flow, which means more nourishment and collagen production for the skin. While you can book a professional facial massage, you can also do it at home with your hands, a jade roller, or other facial massage tools on the market. You can do it yourself. 
To massage your face at home with just your fingers, lubricate your skin with a cream or oil first. Starting at the bottom of the face, use your fingers to gently press the cheeks. 
Apply it on the face and massage around the eyes with just your fingertips. Start at the brow ridge and move around the eye to the outer corner.
Exfoliating can make skin look brighter and younger.
Exfoliating removes old dead skin cells for a smoother, more radiant and even-toned complexion.  The two main types of exfoliation are mechanical, using brushes, scrubs, etc. to remove dead skin cells. and chemicals, which involve the use of acids to dissolve old skin cells. The method that works best for you depends on your skin type. 
If you have dry, sensitive, or acne-prone skin, use a mild chemical exfoliant to avoid irritation.
If you have oily skin, try a mechanical exfoliation or use a stronger chemical exfoliant.
Exfoliate 2-3 times a week. If you have sensitive skin, trim it once a week. It’s tempting to exfoliate every day, but don’t do it — over-exfoliating strips your skin of its natural oils and causes inflammation, which can actually speed up the aging process.
