When it comes to radiant, glowing skin, most people think skincare first. But here’s the truth: no topical serum can replace what you feed your skin from the inside. Your skin is your body’s largest organ, and what you eat directly affects its hydration, elasticity, brightness, and resilience.

The Skin-Nutrition Connection

Healthy skin starts at the cellular level. That glow you’re after? It’s a reflection of how well your skin is regenerating, repairing, and protecting itself from daily stressors and your diet plays a massive role in all of that.

Scientific evidence now supports the power of specific micronutrients like vitamins A, C, D, and E, zinc, selenium, and omega-3 fatty acids in improving skin quality, radiance, and elasticity. These nutrients help combat oxidative stress, reduce inflammation, and support collagen production three essential pillars of skin health.

The Core Nutrients for Radiance

Let’s break down the main players that support a naturally luminous complexion:

• Vitamin C
  Critical for collagen synthesis, vitamin C acts as a powerful antioxidant and brightens the skin. Low levels can lead to dullness and slower wound healing.
• Vitamin A (retinoids and carotenoids)
  Helps regulate skin cell turnover and supports the skin barrier. Deficiencies are associated with dry, flaky skin.
• Vitamin E
  Works alongside vitamin C to protect skin from oxidative damage. It’s especially beneficial when it comes to preventing premature ageing.
• Vitamin D
  Supports skin immunity and has anti-inflammatory properties. It’s involved in skin barrier function and healing.
• Zinc and Selenium
  Essential for tissue repair, antioxidant defence, and overall skin structure. Zinc is also key for controlling oil production and calming inflammation.
• Biotin (Vitamin B7)
  Often recommended for hair, skin, and nails — a deficiency can cause scaly rashes and brittle skin.
• Omega-3 Fatty Acids
  Reduce skin inflammation, improve hydration, and may help with conditions like eczema or psoriasis.
• Polyphenols and Phytoestrogens
  Found in colourful fruits, vegetables, and legumes, these plant compounds improve circulation and help protect collagen and elastin from environmental stress.

What the Research Says

Multiple studies show that diets rich in antioxidants and essential fatty acids are linked to better skin texture, fewer wrinkles, and higher skin hydration levels. For example, a 2024 study combining oral collagen peptides with vitamins and minerals found that participants had significantly improved skin elasticity, radiance, and texture after just three months.

Another study found that a topical complex of vitamin B12 and adenosine triphosphate (ATP) enhanced skin glow and firmness by improving collagen pathways and pigment balance.

Meanwhile, low-glycemic diets and probiotic-rich foods like kefir or fermented vegetables appear to reduce skin inflammation and help regulate the microbiome both on your skin and in your gut.

What to Limit (or Avoid)

A high-sugar, high-fat diet is one of the fastest ways to sabotage your skin. Excess sugar increases advanced glycation end products (AGEs) compounds that stiffen collagen and accelerate wrinkles. Ultra-processed foods also lack the micronutrients your skin desperately needs for repair and resilience.

Hydration matters too. Dehydrated skin looks tired and dull. While water alone won’t hydrate skin like a serum, not drinking enough will definitely show in your complexion.

Supplements: Do They Work?

Some supplements like collagen peptides, curcumin, and astaxanthin show promise for enhancing skin glow, reducing fine lines, and improving texture especially when used alongside a good diet. However, the exact dosage, timing, and long-term effects are still being researched.

If you’re considering a skin-targeted supplement, make sure it includes vitamin C and zinc, as co-factors to support collagen metabolism. And remember: no supplement can undo a poor diet.

What About Skin Elasticity?

Elasticity is what gives skin that bounce-back effect and as we age, we naturally lose it. Micronutrients, particularly vitamin C, vitamin E, zinc, and antioxidants, are proven to support skin structure and reduce wrinkle formation when paired with collagen peptides.

Studies also suggest that increased intake of green and yellow vegetables, plus healthy fats, can lead to firmer, more elastic skin particularly in women aged 30 and up.

Final Thoughts

Radiant skin isn’t about perfection. It’s about nourishment, inside and out. While no food is magic on its own, consistently including nutrient-rich options like berries, leafy greens, oily fish, seeds, sweet potatoes, and nuts gives your skin what it needs to glow.

If you’re dealing with dullness, dryness, or premature signs of ageing, look at your plate before your skincare shelf. Sometimes, glowing skin starts with what’s on your fork.
