- Research suggests vitamins like A, C, D, E, B7 (biotin), and B3 (niacin) are crucial for skin repair, collagen, and protection.
- It seems likely that minerals like zinc and selenium help with healing and antioxidant defense.
- The evidence leans toward essential fatty acids, especially omega-3s, reducing inflammation and maintaining hydration.
- Antioxidants such as coenzyme Q10, glutathione, and carotenoids likely protect against aging and sun damage.
- Amino acids and proteins, particularly collagen, seem essential for skin structure and elasticity.
- Peptides, like collagen peptides, may support skin firmness, though more research is needed.
- Probiotics and fiber, while not nutrients, likely benefit skin via gut health, with ongoing studies.
Vitamins and Their Roles
Vitamins are vital for skin health, supporting repair, collagen, and protection. Here’s a breakdown:
- Vitamin A helps repair and maintain skin, preventing dryness and supporting oil glands. Found in sweet potatoes, carrots, and spinach (WebMD – Nutrients for Healthy Skin).
- Vitamin C is key for collagen, protecting against UV damage, and reducing wrinkles. Get it from citrus fruits and bell peppers (Experience Life – 11 Vital Nutrients for Skin Health).
- Vitamin D supports cell growth and reduces inflammation, sourced from sunlight and fatty fish (Linus Pauling Institute – Skin Health).
- Vitamin E protects against oxidative stress, found in nuts and seeds (WebMD – Nutrients for Healthy Skin).
- Biotin (B7) prevents dermatitis, found in eggs and nuts (Biotics Research – 9 Essential Nutrients for Healthy Skin).
- Niacin (B3) reduces inflammation and supports hydration, found in mushrooms and whole grains (Biotics Research – 9 Essential Nutrients for Healthy Skin).
Minerals and Their Functions
Minerals like zinc and selenium are essential for healing and protection:
- Zinc aids wound healing and fights acne, and it is found in pumpkin seeds and shellfish (WebMD – Nutrients for Healthy Skin).
- Selenium, found in Brazil nuts and sardines, protects against skin cancer (Experience Life—11 Vital Nutrients for Skin Health).

Detailed Categorisation and Analysis
1. Vitamins: Essential Micronutrients for Skin Repair and Protection
Vitamins play critical roles in skin health, supporting cell repair, collagen synthesis, and protection against environmental damage. Below is a detailed breakdown:
- Vitamin A (Retinol, Carotenoids)
– Description: A fat-soluble vitamin, including retinol (active form) and carotenoids (precursors like beta-carotene).
– Role in Skin Health: Essential for skin repair, maintenance, and cell turnover. It prevents dry, itchy, and bumpy skin, supports oil gland function, and reduces signs of aging by promoting new cell growth and protecting against sun damage.
– Why It’s Essential: Deficiency can lead to dry, flaky skin and increased susceptibility to infections, highlighting its role in maintaining the skin barrier.
– Key Sources: Sweet potatoes, carrots, spinach, liver, fish, fortified dairy products.
– Supporting Evidence: Research from WebMD – Nutrients for Healthy Skin emphasizes its role in cell turnover and aging prevention. - Vitamin C (Ascorbic Acid)
– Description: A water-soluble vitamin and powerful antioxidant.
– Role in Skin Health: Crucial for collagen synthesis, providing structure and elasticity to the skin. It protects against free radical damage and UV rays, maintaining hydration and reducing wrinkles. It also aids in wound healing.
– Why It’s Essential: Low levels can cause bruising, bleeding gums, and slower healing, affecting skin integrity.
– Key Sources: Citrus fruits, strawberries, kiwi, bell peppers, broccoli.
– Supporting Evidence: Experience Life – 11 Vital Nutrients for Skin Health highlights its antioxidant and collagen-boosting properties.
2. Minerals: Inorganic Elements for Skin Structure and Repair
Minerals are crucial for enzymatic reactions and maintaining skin integrity. Here’s a detailed look:
-
- Zinc
– Description: A trace mineral essential for numerous enzymatic reactions.
– Role in Skin Health: Essential for skin health, wound healing, and fighting acne. It helps produce new skin cells and protects against UV damage.
– Why It’s Essential: Supports collagen synthesis, modulates inflammation, and maintains the integrity of the skin barrier. Deficiency can mimic eczema and impair healing.
– Key Sources: Pumpkin seeds, meat, shellfish, dairy products, wheat germ.
– Supporting Evidence: WebMD – Nutrients for Healthy Skin highlights its role in healing and acne control. - Selenium
– Description: A trace mineral with antioxidant properties.
– Role in Skin Health: Protects skin cells from oxidative damage and may reduce skin cancer risk. It also supports elasticity.
– Why It’s Essential: Enhances the skin’s antioxidant defence system.
– Key Sources: Brazil nuts, sardines, eggs, whole grains.
– Supporting Evidence: Experience Life – 11 Vital Nutrients for Skin Health notes its protective effects.
- Zinc
