As women age, the body’s ability to repair and protect skin cells naturally declines—leading to thinner skin, dullness, and fine lines. Board‑certified dermatologist Dr. Monique Chheda explains that certain nutrients become especially important after age 40 because they support processes like collagen production, antioxidant defense, inflammation control, and skin repair.
“For women over 40, five important nutrients for maintaining youthful, radiant skin are vitamin C, vitamin E, vitamin A (primarily through carotenoids), omega‑3 fatty acids, and zinc. These nutrients support collagen production, antioxidant defense, inflammation control, and skin repair—all processes that naturally decline with age,” Dr. Chheda says. “Skin aging reflects cumulative damage and slower repair over time. These nutrients become increasingly important after 40 and play a meaningful role in maintaining healthy, radiant skin.”
Here’s how each one helps—and where to find them.

1. Vitamin C
Vitamin C plays a central role in maintaining skin structure by supporting collagen formation and protecting against environmental damage that accelerates aging.
“Vitamin C is essential for collagen synthesis and acts as a powerful antioxidant. It helps protect skin from UV exposure and environmental stressors that accelerate fine lines, wrinkles, and loss of firmness,” says Dr. Chheda.
Where to find it: Citrus fruits, kiwi, berries, bell peppers, and leafy greens.
2. Vitamin E
Vitamin E helps protect cell membranes and strengthen the skin’s moisture barrier, which can improve hydration and help you achieve that natural glow.
“Vitamin E is a lipid-soluble antioxidant that protects skin cell membranes," and it "helps to improve smoothness and overall skin radiance,” says Dr. Chheda.
Where to find it: Nuts, seeds, olive oil, and spinach.
3. Vitamin A (Carotenoids)
Vitamin A, particularly in the form of carotenoids, supports healthy skin cell turnover and helps shield the skin from UV damage, promoting a more even, luminous complexion.
“Vitamin A plays a key role in skin cell turnover. From a dietary standpoint, carotenoids like beta-carotene and lycopene act as antioxidants that accumulate in the skin, helping protect against UV-induced damage,” says Dr. Chheda.
Where to find it: Carrots, sweet potatoes, leafy greens, tomatoes, and peppers.
4. Omega-3 Fatty Acids
Omega-3s help maintain the skin’s lipid barrier and reduce chronic inflammation, supporting hydration, elasticity, and a softer, more resilient appearance.
“Many people don’t get enough omega-3s from their diet alone,” says Dr. Chheda. “Supplementation can be very helpful, especially for those following a vegetarian or vegan lifestyle.”
Where to find it: Salmon, sardines, trout, chia seeds, and flaxseeds.
5. Zinc
Zinc supports skin repair, collagen integrity, and inflammation — all key for maintaining resilience as skin renewal slows down over time.
“Zinc is critical for skin repair, DNA synthesis, and inflammation control. As we age and skin renewal slows, adequate zinc helps support wound healing, collagen integrity, and overall skin resilience,” says Dr. Chheda.
Where to find it: Shellfish, pumpkin seeds, legumes, and whole grains.
Food First, Supplements When Needed
When it comes to nutrients, Dr. Chheda recommends a food‑first approach whenever possible.
“I generally recommend a food‑first approach, with targeted supplementation when dietary intake or absorption is insufficient," Dr. Chheda notes.
That means prioritizing colorful, whole foods for most of your nutrients—and considering supplements, especially omega‑3s, if you aren’t meeting needs through diet alone.
