Nourish: Feed Your Skin From Within
Your diet shows on your skin
One of the largest studies on food and skin followed 4,025 women aged 40–74. Those who ate more vitamin C had fewer wrinkles and less age-related dryness. A higher intake of linoleic acid – an essential fatty acid found in seeds, nuts and plant oils – was linked with less dryness and thinning of the skin, while diets high in fat and carbohydrates overall were linked with more wrinkles.
The study shows a link, not proof of cause and effect – but it matches what we know about how skin is built: vitamin C is needed to make collagen, and linoleic acid is a building block of the skin barrier.
Eat for your skin
In a randomised trial, women who ate 55 g of tomato paste with olive oil every day for 12 weeks – rich in the red pigment lycopene – had better protection against UV-induced redness and signs of less collagen damage than the control group. It is not a replacement for sunscreen, but it shows that colourful plant foods can support the skin from within.
Omega-3 fatty acids, from oily fish, walnuts, flaxseed or algae, are also being studied for their potential to help protect skin against UV damage. Berries, citrus, peppers and leafy greens add vitamin C.
Water – with a nuance
Does drinking more water give you more hydrated skin? A study of 49 women found that adding about two litres of water a day for a month improved hydration in both the surface and the deeper layers of the skin – most clearly in those who drank little to begin with.
In other words: if you already drink enough, more water won’t transform your skin. If you don’t, it’s one of the simplest things you can change.
Feed the barrier from the outside
The skin barrier is made of lipids – ceramides, cholesterol and fatty acids. Plant oils and butters are rich in fatty acids similar to the skin’s own, so they can support the barrier from the outside while your diet does its part from within.
Reboost Balm is built on shea butter and argan oil, Lift Serum contains prickly pear seed oil rich in linoleic acid and vitamin E, and Recovery Serum adds ceramides. Read more about vitamin C and vitamin E in Nature’s Most Potent Superfruits.
