In my dermatology practice, women over 40 ask what helps skin age well. My five basics are vitamin C, vitamin D, vitamin A from beta carotene, zinc, and selenium. C supports collagen. D supports the barrier and calms inflammation. Beta carotene helps tone. Zinc helps repair. Selenium supports antioxidant enzymes. Food first. Citrus, peppers, berries, and kiwi give vitamin C. Fatty fish or fortified dairy helps vitamin D. Orange vegetables cover beta carotene. Oysters or pumpkin seeds add zinc. Brazil nuts add selenium. I add a supplement only when diet or labs show a gap. In 2025, Pullar et al studied 24 adults eating two SunGold kiwifruit daily, about 250 mg vitamin C, for 8 weeks. Skin vitamin C, thickness, and epidermal renewal increased.
Vitamin C, Vitamin E, Vitamin A in its retinol form, zinc, and collagen-supportive minerals like silica are the ones I tend to focus on for women over 40. Each of these plays a part in keeping skin resilient--whether that's through supporting elasticity, maintaining moisture, or helping the skin handle oxidative stress. Vitamin C is central to collagen production and helps temper free-radical damage. Vitamin E adds another layer of antioxidant support and helps the skin hold onto moisture. Vitamin A influences how quickly skin cells renew themselves, though it's potent enough that it should be used with some guidance. Zinc contributes to repair and helps calm inflammation, and silica supports the structure of collagen and other connective tissues. Food should always be the starting point. Vitamin C shows up naturally in citrus, peppers, and berries. Vitamin E is abundant in nuts, seeds, and plant oils. You'll get Vitamin A from orange vegetables and dark greens. Zinc is available in legumes, shellfish, and whole grains, while silica is found in oats, brown rice, and even bananas. That said, absorption can slow as we age, and sometimes diet alone doesn't cover what the skin needs, so supplements can play a useful supporting role. A mix of both--good nutrition paired with well-formulated supplements--tends to be the most realistic approach, ideally with a clinician keeping an eye on things over time.
I tell people worried about aging skin to look at their plate first. Colorful produce, nuts, and seafood give you the vitamins A, C, E, zinc, and omega-3s that actually work. I see patients who focus on food get more natural results. Supplements can help, but food is always number one. Talk to your doctor to see what your skin responds to.
My work at Superpower shows that for women over 40, vitamin C, E, D, zinc, and collagen are key for keeping skin springy and repairing itself. We find people who get these from foods like citrus, nuts, and leafy greens have more stable results. Still, if your bloodwork shows you're low, add a supplement since everyone's body absorbs things differently.
I look at five nutrients with the most importance to me when working with women over forty who would like their skin to appear clearer and evenly toned, over time. Those nutrients include Vitamin C, zinc, selenium, copper, and Vitamin D, and Vitamin C is what helps keep your collagen levels consistent while helping you get a bright appearance. Zinc will help control the inflammation of acne or other skin irritations and support skin repair after an episode of irritation. Selenium will protect skin cells from everyday stress that leads to visible signs of aging. Copper will support the structural integrity of your collagen so your skin can maintain its elasticity. Vitamin D helps regulate your body's immune system responses, which many times manifests as less redness and less dryness on the surface of your skin. Nutrients need to be delivered through food first because that way your body will get them in their most natural forms. Berries, bell peppers, and citrus fruits are good sources of vitamin C. Oysters, beef, and pumpkin seed contain zinc, brazil nuts and seafood contain selenium, and copper can be found in cashews, cacao, and organ meats. Because your body absorbs vitamin D better through sunlight than through diet, blood tests help determine if you have real nutritional gaps that require supplementation.

A: Vitamin C, Vitamin A (ideally from food as beta carotene), Vitamin E, Zinc, Selenium. These five support collagen, healthy cell turnover, antioxidant defense and calmer inflammation, which all matter as skin naturally thins and dullness shows more easily after 40. Q: what are the benefits of taking these vitamins and minerals? A: Vitamin C supports collagen and helps brighten the look of uneven tone. Vitamin A supports smoother texture and more even looking skin renewal, but too much preformed vitamin A can be harmful so dose matters. Vitamin E, Selenium help defend against oxidative stress that contributes to dullness and visible aging. Zinc supports wound healing, barrier repair and inflammation control which can mean fewer flare ups and faster recovery from irritation. Q: where can we find these vitamins and minerals and is best to consume them through food or supplement/both? A: Food first is best because it comes with protein, healthy fats and phytonutrients that help skin in a more complete way. Vitamin C is high in citrus, berries, kiwi, bell peppers and broccoli. Beta carotene sources for vitamin A include sweet potatoes, carrots, spinach and kale, while Vitamin E is found in almonds, sunflower seeds, avocado and olive oil. Zinc is in seafood, meat, beans and pumpkin seeds, while Selenium is in eggs, fish and Brazil nuts, often 1 to 2 nuts can be enough. Supplements can help when diet is limited or labs show a true gap, but I advise avoiding megadoses since excess vitamin A, Zinc, Selenium and Vitamin E can cause side effects or interact with medications.
