Interesting! Eating lots of antioxidants (sweet potatoes, tomato paste, greens) can protect our skin just like wearing SPF 4 sunscreen (without the nasty chemicals) 😎 🌱💪🏼💕
Sunscreens work almost immediately and offer much stronger shielding from the sun than dietary protection, which builds up slowly over weeks. Dietary protection only achieves an SPF of 4, compared to the SPF of 10 to 40 (or even higher) that we can get from topical sunscreens.
On the other hand, sunscreens have to be deliberately applied in sufficient amounts and with sufficient coverage––including all the hard-to-reach places––and then can still rub off, wash off, or be sweated off, whereas protection from plants is ever-present and built-in all over.
For example, eating a lot of antioxidant-rich foods, such as tomato paste, for ten weeks (but not four) before swimsuit season can reduce the redness of a sunburn by 40 percent. So, if we forget to reapply our sunscreen, our diet can help as a secondary approach to protecting our skin.
We should eat more antioxidant-rich plants and apply our sunscreen to protect our skin. Combined, these modalities complement each other.
