5.   Oatmeal
Oatmeal soothes sunburn due to its antioxidant, antifungal and moisturizing properties. Oatmeal contains free radical scavengers called saponins. Oatmeal also stimulates T-cell production - boosting the immune system and helping regenerate the skin. Oatmeal can be mixed with water and used topically on sunburn or as an exfoliator prior to sun exposure.
6.   Cucumber
Cucumber helps the body produce collagen, the main structural protein in the skin. 96% of a cucumber is water, so cucumber is extremely hydrating. To benefit from cucumber’s skin care qualities the peel should also be consumed. The peel contains silica that firms up the skin. Additionally cucumber contains vitamin C, caffeic acid, potassium and vitamin K. Vitamin K helps the skin heal, so is great for soothing sunburn. Caffeic acid is high in antioxidants and helps protect the skin from oxidative stress and DNA damage.
7.   Tomatoes
Similar to strawberries, tomatoes contain lycopene, which is a carotenoid that gives the tomato its red color. Lycopene is an antioxidant that protects the skin from cellular damage. Tomatoes are also high in vitamin C – just one cup of tomato juice provides 188.9% DV of vitamin C. Tomatoes are also rich in antioxidants, anti-inflammatory and help balance the body’s pH.  One study  showed how the phytochemicals in tomatoes mitigated sunburn in animal models.
8.   Water melon
92% of watermelon is water, so they are great for keeping the skin hydrated. Watermelon is also filled with skin-healthy nutrients like vitamins A, B6 and C. Watermelon also contains the antioxidant lycopene and the amino acid arginine. Both help protect the skin from photoaging while aiding in blood flow and protein formation.
9.   Carrots
Carrots are bursting with beta-carotene, which the body converts to vitamin A. Beta-carotene also reduces inflammation from sunburn. Sun exposure creates additional free radicals so the vitamin C from carrots is also great to protect the skin from sun damage. Carotenoids signal gene expression at a cellular level and offer  photoprotective qualities  that can mitigate sun damage.
All of the foods listed above can be used topically or ingested to yield skin-healthy benefits.
