8 Essential Nutrients for Glowing Skin
Last updated 29 June 2026 · 10 min read
Glowing skin is not just about looking shiny or dewy. It is usually a sign of skin that is well hydrated, well protected and supported by a consistent routine, a balanced diet and enough daily care to keep the skin barrier happy.
While skincare can make a visible difference to the way your skin looks and feels, it works best when paired with the basics your body needs from the inside out. Nutrients such as vitamin C, vitamin A, zinc, omega 3 fatty acids, vitamin E, biotin, water and antioxidants all play different roles in skin health, from collagen support to hydration, oil balance and repair.
This guide explains the 8 essential nutrients for glowing skin, where to find them in food and how to support your glow topically with Australian skincare products available at VAMS Beauty.
KEY TAKEAWAYS
- Glowing skin is supported by both topical skincare and whole-body nutrition.
- Vitamin C, zinc, vitamin A, omega 3 fatty acids and vitamin E are especially relevant to skin health.
- Daily broad-spectrum SPF is essential in Australia, because UV exposure contributes to premature ageing and skin damage.
- Hydration matters, but water alone will not replace a moisturiser, serum or sunscreen.
- The best glow routine is consistent, barrier-supportive and matched to your skin type.

The 8 Essential Nutrients for Glowing Skin
Skin is an organ, which means it needs nutrients, hydration and protection to function well. A topical product can help support the surface of the skin, but nutrition supports the biological processes underneath, including collagen formation, cell renewal and wound healing.
1. Vitamin C: the collagen-supporting antioxidant
Vitamin C is one of the best-known nutrients for glowing skin because it supports normal collagen formation and acts as an antioxidant. Collagen is a structural protein that helps give skin its firmness and bounce. When skin is exposed to UV radiation, pollution and daily stressors, antioxidants help reduce the impact of free radicals, which are unstable molecules that contribute to oxidative stress.
From food, vitamin C is found in citrus fruits, strawberries, kiwi fruit, capsicum, broccoli, tomatoes and leafy greens. For most people, a varied diet is the best place to start. Better Health Channel notes that vitamins and minerals are needed by the body in small amounts and are best obtained from a healthy, varied diet that includes the five food groups.
In skincare: vitamin C is commonly used to brighten the look of dull skin, support a more even-looking tone and improve radiance over time.
2. Vitamin A: the skin renewal nutrient
Vitamin A supports normal skin function and plays a role in the way skin cells grow and renew. In skincare, vitamin A derivatives such as retinoids are well known for supporting smoother-looking skin, but they are not suitable for everyone, especially during pregnancy or breastfeeding unless cleared by a healthcare professional.
Food sources of vitamin A and beta-carotene include sweet potato, carrots, pumpkin, spinach, kale, apricots, eggs and dairy foods. Rather than thinking of vitamin A as a “more is better” nutrient, aim for balance. High-dose vitamin A supplements can be harmful and should only be used with professional guidance.
In skincare: if your skin does not tolerate retinoids, gentle exfoliation and barrier support can still help improve dullness and uneven texture.
3. Zinc: the skin health and sun protection mineral
Zinc is an essential mineral involved in immune function, wound healing and skin health. Healthdirect Australia notes that zinc supports skin health and that low zinc can contribute to skin changes and slow wound healing.
Food sources include pumpkin seeds, lentils, chickpeas, beef, oysters, nuts, wholegrains and dairy foods.
Topically, zinc oxide is widely used in mineral sunscreen. In Australia, sunscreen matters because UV radiation is one of the biggest contributors to premature ageing, pigmentation and skin damage. Cancer Council Australia recommends SPF50 or SPF50+ broad-spectrum sunscreen when UV levels are 3 or above, along with other sun protection measures such as clothing, shade, hats and sunglasses.
4. Omega 3 fatty acids: the comfort and barrier-support nutrients
Omega 3 fatty acids are essential fats, meaning the body cannot make enough on its own and needs them from food. They are important for general health and may help support skin comfort, especially when dryness and inflammation are part of the picture.
Food sources include salmon, sardines, trout, chia seeds, flaxseeds, walnuts and hemp seeds. If you do not eat fish, plant-based omega 3 sources can still be helpful, though the body converts them differently.
In skincare: botanical oils rich in essential fatty acids can help soften the skin surface and support a more comfortable-feeling barrier. They do not replace dietary omega 3s, but they can be beautiful for dry, mature or dull skin.
5. Antioxidants: the free radical defenders
Antioxidants are compounds that help defend against oxidative stress. In skin terms, oxidative stress can be triggered by UV exposure, pollution, smoke and other environmental factors. Over time, this can contribute to dullness, uneven tone and visible signs of ageing.
Antioxidants are found in colourful plant foods such as berries, grapes, leafy greens, citrus fruits, herbs, cocoa, green tea and deeply coloured vegetables.
In skincare: antioxidants are often used in serums, moisturisers and facial oils to help support radiance and environmental defence. Ingredients such as vitamin C, vitamin E, Kakadu Plum, grape extracts and botanical oils are all commonly used for this reason.
6. Water: the everyday hydrator
Water supports whole-body health, including the skin. Dehydration can make skin look flatter, tighter or more tired, but drinking more water is not a magic cure for every skin concern. Skin hydration also depends on your barrier, environment, skincare routine and whether your skin can hold onto water.
Water-rich foods include cucumber, watermelon, oranges, soups, leafy greens and berries. If you drink coffee, exercise, spend time in air conditioning or live in a hot climate, you may notice your skin feels better when hydration is more consistent.
In skincare: humectants such as glycerin and hyaluronic acid help draw water into the upper layers of the skin, while moisturisers and oils help reduce water loss from the skin surface.
7. Vitamin E: the lipid-loving skin smoother
Vitamin E is a fat-soluble antioxidant. It works well in skincare because it sits comfortably within oil-based formulas and can help condition the skin surface. In food, vitamin E is found in nuts, seeds, avocado, spinach and plant oils.
Vitamin E is often paired with vitamin C in skincare because both are antioxidants. In a glow routine, vitamin E-rich oils and creams can be especially helpful for skin that feels dry, rough or lacking softness.
In skincare: look for vitamin E in facial oils, moisturisers, serums and creams designed to soften and nourish the skin barrier.
8. Biotin: the beauty vitamin with a balanced role
Biotin, also known as vitamin B7, is involved in the metabolism of fats, carbohydrates and proteins. It is often marketed for hair, skin and nails, but most people who eat a varied diet get enough biotin from food.
Food sources include eggs, nuts, seeds, wholegrains, legumes and bananas. If you suspect a deficiency or are considering supplements, it is best to speak with a healthcare professional. Some supplements can interfere with pathology tests, so they should be used thoughtfully.
In skincare: biotin is less commonly used as a hero topical ingredient than vitamin C, vitamin E or zinc oxide. For a glow routine, it is usually more useful to focus on a balanced diet, daily SPF, hydration and barrier support.
How Nutrients Support Your Skincare Routine
Nutrition and skincare do different jobs. Food supports the body from within, while skincare supports the skin surface. For glowing skin, the strongest approach is not one or the other, it is both.
| Nutrient | Supports | Skincare pairing |
|---|---|---|
| Vitamin C | Collagen formation and antioxidant defence | Vitamin C serum |
| Vitamin A | Skin renewal and normal skin function | Gentle exfoliation or retinoid alternative |
| Zinc | Skin health and wound healing | Zinc oxide mineral SPF |
| Omega 3s | Comfort and barrier support | Nutrient-rich facial oil |
| Water | Hydration and whole-body function | Hydrating toner, serum and moisturiser |
