When we talk about glowing skin, most conversations start and end with creams, serums and facials. But according to a Stanford expert, that approach only scratches the surface. Real skin health begins much deeper inside the body.
In a recent Instagram post, Stanford expert Prashant Desai explained that skin health is influenced by inflammation, collagen strength, gut health and hydration, not just by the products we apply daily. What you eat and how your body functions internally can shape how your skin looks on the outside.
Why Skin Health Starts From Within
According to Prashant Desai, HYDRATION is one of the most overlooked factors affecting skin quality. Even mild dehydration can reduce skin elasticity and make it appear dull and tired. Water-rich foods like cucumber help maintain hydration from within, supporting firmness and a healthier glow.
He also points out the role of ANTIOXIDANTS in slowing skin ageing. For example, Pomegranate is rich in polyphenols such as ellagitannins and flavonoids. These compounds help reduce oxidative stress in the body and protect collagen from breaking down. Since collagen is responsible for skin strength and smoothness, protecting it is essential for youthful-looking skin.
GUT HEALTH is another major player. Papaya contains papain, a digestive enzyme that supports better digestion. A healthier gut is directly linked to clearer skin through what scientists call the gut–skin axis. When digestion improves, inflammation often goes down, which may result in fewer breakouts and less redness.
HEALTHY FATS also matter more than many realise. Avocado provides monounsaturated fats and vitamin E, both of which help repair the skin barrier. A strong barrier keeps moisture in, supports healing, and improves overall skin radiance.
The Role of Inflammation
Inflammation is often the hidden enemy behind many skin problems. Acne, redness, pigmentation and premature ageing are all linked to chronic inflammation in the body.
As mentioned by Prashant Desai, natural compounds like curcumin from turmeric and gingerols from ginger help reduce inflammatory markers such as CRP and TNF-α. Lower inflammation can calm irritated skin and support a more even tone over time.
This explains why topical products alone may not deliver lasting results. While creams work on the surface, nutrition changes how the skin functions at a biological level. When the body is nourished properly, the skin responds naturally.
A Smarter Way To Support Skin Health
There is no single “superfood” or overnight solution. Skin health improves when hydration, gut health, healthy fats and anti-inflammatory foods become part of daily life.
According to Prashant Desai, eating for your skin is not a trend but a long-term habit. When nutrition supports the body from within, skincare products can work better as a supporting tool, not the main solution.
In the end, clear and youthful skin is less about what you apply and more about how well you care for your body every day.
