Avocados—Your Skin’s Moisturizing BFF
Avocados aren’t just for toast, babe, they’re a full-blown skincare hack, a moisturizer you can eat. Packed with healthy fats, including oleic acid, they help lock in moisture and strengthen your skin’s barrier, giving you a plump, hydrated, and radiant look.
It’s also rich in vitamin E, which helps fight free radicals and protects your skin from oxidative stress. And let me tell you, avocado doesn’t only help with the skin; it helps with hair growth!.
Avocados contain biotin, which promotes keratin production, resulting in healthy hair and nails. So, yeah, avocado is a total glow-up in a bite.
You can try adding an avocado:
- To your smoothies
- Mashing it on sourdough with lemon
- Slicing into salads for an extra glow-up
Sweet Potatoes—The Beta-Carotene Bomb
Think of sweet potatoes as your skin’s secret weapon against dullness. They’re packed with beta-carotene, a plant-based compound your body turns into vitamin A—the same powerhouse ingredient found in retinol.
A high-vitamin A diet helps your skin cells renew faster, meaning your dull, dead layers get replaced with fresh, radiant, and firm skin. Studies show that beta-carotene may even offer natural sun protection over time.
Snack ideas:
- Roast sweet potato wedges with paprika
- Mash with olive oil and cinnamon
- Add cubes to nourish bowls with greens + tahini
Tomatoes—Natural SPF in a Fruit
Okay, tomatoes aren’t a replacement for sunscreen (don’t play), but they do contain lycopene, a powerful antioxidant that protects your skin from sun-induced aging. They also help fight off dullness and uneven skin tone.
A study published in the British Journal of Dermatology found that participants who ate tomato paste daily had 33% more protection against sunburn and higher levels of procollagen, which helps to keep the skin firm.
But here’s the real tea: not only does eating tomatoes help with your skin, but applying them directly to your skin can also work wonders. It helps with exfoliation, acne control, oil reduction, and pore tightening. That’s a big win for your glow game.
Glow hacks:
- Add cherry tomatoes to pasta
- Cook with olive oil to boost lycopene absorption
- Try tomato juice with a squeeze of lemon in the morning
Spinach—The Glow-Getter Green
Spinach is your skin’s detox bestie. Rich in vitamins A and C, folate, iron, and all glow boosters, it helps with collagen production, supports cell repair and blood circulation, and reduces signs of aging, making your skin look plump and youthful.
Blended spinach can help detoxify your skin from within, fade dark circles, and prevent breakouts caused by hormonal imbalances. So, just a cup a day, and your skin might just start thanking you with a whole new level of radiance.
Nuts & Seeds—Your Skin’s Favorite Crunch
Almonds, walnuts, chia seeds, and flaxseeds contain good fats, zinc, and selenium that your skin craves. These nutrients regulate oil production, reduce inflammation, and strengthen your skin barrier.
