Include tomatoes in your daily diet to keep your skin firm and protect it against sunburn (equivalent of a very low factor sun cream).

Tomatoes contain a powerful antioxidant called Lycopene, which offers protection against sunburn. A study conducted at Manchester and Newcastle Universities found that people who added five tablespoons of tomato paste to their daily diet had 33 percent more protection against sunburn, and much higher levels of pro-collagen, a molecule which gives the skin its structure and keeps it firm.
