We include apple powder in Sun-Kissed because apples are high in antioxidant polyphenols and flavonols, including procyanadins and quercetin. Studies suggest that quercetin may be associated with reduced skin damage in response to UVB exposure by slowing collagen degradation and reducing inflammatory markers.

The beautiful red beet gets its color from red pigments called betalains that act as antioxidants. Beets are also rich in carotenoids and vitamin C. Carotenoids accumulate in the skin and may act as antioxidants to support your skin's defense against sun damage. Vitamin C is also an antioxidant and is necessary to form collagen.

Green algae produces high levels of astaxanthin, a highly bioavailable antioxidant similar to beta-carotene. One study of human skin cells has shown that astaxanthin may help lessen hyperpigmentation in response to inflammatory chemicals that can be released by UV exposure. Astaxanthin is also being researched for its potential to help slow or reduce issues like moisture loss, rough skin, and the appearance of aging in skin.

Carotenoids are a group of molecules that give fruits and vegetables their orange, yellow, and red colors. The most famous carotenoids include beta-carotene, which is found in carrots and pumpkin, and lycopene, found in tomatoes and watermelon. Carotenoids accumulate in the skin and may act as antioxidants to support your skin's defense against sun damage. One study found that taking beta-carotene may be associated with reduced appearance of wrinkles and a more healthy response to UV light. Another set of studies has found that consuming beta-carotene may be associated with reduced risk of sunburn.

You've probably heard about the benefits of the Mediterranean diet, many of which relate to eating olives and olive oils. Olives have high levels of phenolic compounds like the antioxidant hydroxytyrosol. We use an olive fruit extract standardized to hydroxytyrosol levels because studies suggest that hydroxytyrosol may reduce inflammatory signalling and cellular senescence (a marker of aging) in skin cells exposed to UVA light.
