Fruit, Fruit, Fruit and MORE fruit.
There are an incredible amount of fruits that can give you anti-aging benefits. This involves more than just eating fruit as well. You can make masks, lotions, and creams just by blending up some fruits that you can find at the grocery store. Tomatoes are truly a miracle.
I have a list of some benefits and which fruit to use on my website which can be seen here if you are interested. Maybe not entirely for ageing but tips on overall health, nails, facial care etc. Hope this helps.
