I’ve worked in health and wellness for years—including my time as a health advisor at the Life Extension Foundation—and one thing I’ve learned is this: your daily food choices can influence how your skin looks and feels as you get older.

The good news? You don’t need pricey products or complicated routines. Just real, skin-nourishing foods you can grab at any grocery store.

In this guide, I’ll break down the best skin-nourishing foods, the key nutrients that support collagen, hydration, and your skin barrier, and a few easy swaps that add up over time.

You don’t need pricey products—just real food like this that you can grab at any grocery store.

There’s a lot of hype out there, but certain nutrients can help support healthy-looking skin as we age. I’ll share the ones I rely on and easy ways to add them to everyday meals.

One thing I noticed?

Some foods seemed to make my face look puffier, especially around my eyes and lower face. Once I cut back on a few of those foods (I’ll show you below), I noticed less puffiness, especially around my eyes.

How food affects your skin as you age

As we get older, collagen production slows down, and our skin can become drier and less resilient. Food won't fix everything, but a healthy diet can help give your skin the nutrients it needs.

Certain nutrients, like vitamin C, healthy fats, and antioxidants, play a role in collagen production and normal skin function. It's not about finding one miracle food, but getting a good mix of nutrients over time.

Quick note: A sagging jowl line is one of those changes many of us start to notice over time. Now food alone won’t lift or reshape it. But what you eat can support skin hydration, collagen structure, and overall tone. I’ll cover the food side on this page and link you to my simple jawline lift routine.

Color-rich foods that support aging skin

A simple way to support your skin from the inside is to eat a mix of naturally colorful foods. Different colors tend to deliver different plant compounds that support skin resilience and overall skin health over time.

• Red & pink: tomatoes, red peppers, watermelon, strawberries (great everyday antioxidant support)
• Orange & yellow: carrots, sweet potatoes, squash, bell peppers (supports normal skin renewal)
• Green: spinach, kale, broccoli, mustard greens, avocados (collagen support + comfort for dry skin)
• Blue & purple: blueberries, blackberries, purple grapes (skin-cell protection support)
• Pink-ish seafoods: salmon, shrimp, egg yolks (supports elasticity and smoothness)
• Sulfur-rich: garlic, onions, leeks (collagen + keratin support — my grandmother swore by these)

You don’t have to eat all of these every day. Just pick a few favorites, mix and match, and add them where they fit. Smoothies are one of the easiest ways to sneak in berries, greens, chia seeds, yogurt, or avocado without making a whole meal out of it. See my glow smoothies for skincare after 40 for a few easy blend ideas.

Curious why these foods help your skin—and easy, real-life ways I actually use them—keep reading.

Sulfur-rich foods (like garlic, onions, and leeks)

Garlic, onions, and leeks are good sources of natural sulfur compounds. Your body needs sulfur to help make proteins like keratin, which helps keep your skin, hair, and nails strong. These vegetables also contain antioxidants that may help support healthy skin as we age.

I grew up eating garlic and onions in just about everything, thanks to my Polish grandmother. Back then, I didn’t know why she used them—I just liked the flavor.

My veggie tray before roasting. Garlic and onions add plenty of flavor, while the colorful vegetables bring a nice mix of nutrients.

ABZ Tip: I roast a big tray of vegetables once a week and always include onions or garlic. It’s one of the easiest ways I know to eat more skin-nourishing foods. They're great tossed into soup, salads, pasta, scrambled eggs, etc.

Vitamin C (citrus, berries, and peppers)

Vitamin C helps your body make collagen, the protein that gives skin some of its strength and structure. It also works as an antioxidant, helping protect cells from everyday damage.

You don't need mega doses. Getting enough vitamin C from foods like berries, citrus fruits, and bell peppers is a simple way to support healthy skin as you age.

ABZ Tip: I toss berries into yogurt or oatmeal and add red or yellow bell peppers to salads and quick stir-fries. I usually try to work one or two vitamin-C-rich foods into my day.

Plant pigments (carotenoids & lycopene): why color matters

The natural pigments that give fruits and vegetables their bright colors are called carotenoids. They act as antioxidants in the body, helping protect cells from everyday damage. That's one more reason I like eating a mix of colorful foods.

ABZ Tip: I also lean on leafy greens like spinach here—I keep frozen spinach on hand and toss it into soups, pasta, or blend it into my skin-clearing smoothies when I want something easy.

Astaxanthin & omega-3s (salmon, shrimp, and eggs)

Salmon and shrimp offer some nice skin benefits, especially as we get older. Omega-3 fats help support your skin's moisture barrier, while astaxanthin, a powerful antioxidant, shows promise for improving skin hydration and elasticity.

ABZ Tip: Fresh salmon can be expensive, so don't overlook canned salmon! I like adding it to scrambled eggs, salads, or making simple salmon patties. It's an affordable way to get more omega-3s into your diet.

Vitamin E & healthy fats (avocado, olive oil, and nuts)

Avocados, olive oil, and nuts provide healthy fats and vitamin E, nutrients that help keep your skin healthy. Vitamin E acts as an antioxidant, while healthy fats help support your skin's natural moisture barrier—especially important as skin tends to get drier with age.

ABZ Tip: I drizzle olive oil over veggies, add avocado to toast or salads, or grab a handful of nuts. Easy upgrades that actually taste good.

Polyphenols & EGCG (green tea, black tea, and grapes)

Green tea, black tea, and grapes contain polyphenols—natural antioxidants that help protect cells from damage. They're an easy, affordable way to add more skin-supporting nutrients to your diet.

Green tea also contains EGCG, an antioxidant being studied for its possible skin benefits. And if you like using green tea on your skin, too, try this green tea facial cleanser recipe.

ABZ Tip: I drink green or black tea often and sometimes reuse the tea bags as quick, chilled eye compresses. Simple, old-school, and it works for me.

Foods that may work against skin health when eaten often

What you eat regularly matters, too. Eating too much sugar and heavily processed foods may affect your skin over time.

One reason is glycation. That's when sugar attaches to proteins like collagen and elastin, which can make skin less firm and flexible as we age.

I first learned about glycation years ago when I worked at Life Extension Foundation. It stuck with me because collagen and elastin help give our skin its bounce.

Over time, glycation can make these proteins less flexible, which may contribute to wrinkles and changes in skin firmness. Diet is just one factor in skin aging, but it may also play a part in how our skin looks, including dullness.

Foods and habits that may affect your skin over time:

• Added sugars: Including hidden sugars in sauces, cereals, and sweet snacks.
• Refined carbs: White bread, crackers, and sugary baked goods, especially when eaten often.
• Fried and heavily processed foods: These can be high in saturated fats, salt, and calories.
• High-sodium meals: Frozen dinners and takeout can contribute to temporary puffiness in some people.
• Sugary drinks and alcohol: Easy sources of extra sugar or calories. Alcohol can also contribute to dehydration.

This doesn't mean you need to cut everything out. It's what you eat most often that matters, not the occasional treat.

Easy food swaps to support better skin

You don't have to change your whole diet to eat better. Sometimes, a few simple food swaps are all it takes to add more skin-friendly nutrients to your meals.

No rules, no pressure—just a few simple ideas you can try when it works for you.

Here are some of my go-to swaps:

• Sugary cereal → Plain Greek yogurt or oatmeal with berries or chia
• White bread toast → Sprouted grain toast with avocado
• Soda or sugary drinks → Iced green tea with lemon
• Potato chips → Roasted chickpeas or air fryer sweet potato chips.
• Candy or baked goods → A few squares of dark chocolate + almonds
• Creamy salad dressings → Olive oil with lemon or balsamic
• Full pasta bowl → Half pasta, half spaghetti squash (My favorite dinner swap—plus a great time to add that garlic!)

These aren’t rules—just easy ways to work in more nutrients without giving up flavor.

Example of my favorite skin-friendly snacks

When I want something salty, I grab a small bowl of olives. They're satisfying, provide healthy fats, and are easy to keep on hand.

For something sweet, I like a few squares of dark chocolate with almonds. Simple snacks that taste good and add a little extra nutrition to my day.

Not perfect—just smarter food swaps for skin health

Eating better doesn't mean giving up everything you enjoy. It's about making a few healthier choices most of the time.

And don't overlook frozen or canned vegetables, beans, and jarred tomato paste. I use them all the time! They're affordable, nutritious, and make it easier to put together a quick meal.

Takeaway: Small food choices, big skin difference

You don't need a perfect diet to support healthy skin. Small choices, like adding more colorful vegetables, healthy fats, and nutrient-rich foods, can make a difference over time.

I don't aim for perfect, either. I just try to eat well most of the time and enjoy the foods I love along the way.

Food is just one part of caring for your skin. For the topical side of things, including cleansing, moisturizing, exfoliation, and sunscreen, see my Skincare Over 40 Guide.
