Give yourself a hand—or two.
Use a good hand cream frequently, and look for one that has sunscreen included. Brighten dull hands by exfoliating regularly: mix sea salt with lemon juice and gently scrub into your hands with a soft toothbrush.
Eat more greens and reds.
Vitamin K—in kale and other green vegetables—helps your blood coagulate, reducing the impact of bruising. Lycopene in tomatoes gives the skin powerful protection against UV rays.
Eat oily fish.
Salmon and other oily fish are rich in DMAE (dimethylaminoethanol), a compound that boosts muscle tone and is one of the must-have ingredients in expensive “mature” skin creams. Eating oily fish twice a week offers the same benefits.
