Skin Nourish Watermelon Smoothie Recipe

↓ Jump to Recipe

Created by a Registered Dietitian, this Skin Nourish Watermelon Smoothie is skin food in a glass. Watermelon is a hydrating fruit packed with skin-friendly nutrients, including vitamin C, lycopene, and water. Blend it with flaxseed meal, chia seeds, Greek-style yogurt, and mint, and you get a refreshing, protein-rich smoothie with fiber and healthy fats. Plus, nutrients your body uses to make collagen, which helps keep skin firm and smooth. (Dairy-free.)

One glass provides 24 grams of protein for around 300 calories.

Watermelon is rich in the antioxidant lycopene, a carotenoid that gives it its bright red color. Lycopene may help protect your skin from the effects of too much sunlight, like redness, uneven tone, and early signs of aging. It works like a gentle, natural boost to your skin’s defenses. Flax and chia seeds add fiber and healthy fats, while Greek-style yogurt provides the amino acids proline and glycine—key building blocks your body uses to make collagen. The result? A smoothie that tastes amazing and helps your skin glow from the inside out.

This Watermelon Smoothie recipe was inspired by my Juice with Chia Seeds and Blueberry Mango Smoothie with Chia Seeds (no banana) on my site.

👩🏼‍🌾 Ingredients & Health Benefits

Below are some notes about the ingredients from me, as an expert in nutrition.

Watermelon, chia seeds, flaxseed meal, mint, Greek yogurt, nondairy milk, and hemp hearts in a blender.

Watermelon: Hydrating and rich in lycopene and vitamin C to support skin health.
Flaxseed meal: High in omega-3s and fiber to reduce inflammation and support gut-skin balance. When your gut is balanced and healthy, it can reduce inflammation and support immune function, keeping skin clear and calm.
Greek-style yogurt: Packed with protein and collagen-building amino acids like proline and glycine.
Hemp hearts: 3 tablespoons of hemp hearts give you egg-level protein, plus skin-loving essential fats and minerals like zinc and magnesium.
Nondairy milk: Adds creaminess and nutrients like calcium and vitamin D, depending on the type. Soymilk contains isoflavones, natural plant compounds that may help reduce wrinkles, lighten dark spots, and boost skin hydration. In one study, women who took soy protein with isoflavones for 6 months saw smoother, more even-toned skin and better moisture.
Mint: Refreshing and rich in antioxidants.
Chia seeds: Packed with fiber, omega-3s, and antioxidants, chia seeds support gut and skin health—and naturally thicken smoothies thanks to their gel-like texture.
Date (optional): Naturally sweet and rich in fiber, potassium, and antioxidants that support digestion and provide long-lasting energy without added sugar.

See the printable recipe card below for quantities.

🍉 Substitutions

Frozen banana: Add half a frozen banana instead of dates for a thicker texture and natural sweetness.
Ice cubes: Add 2 to 4 cubes for a frostier texture without adding calories.
Yogurt: Use Greek-style yogurt for extra protein. For a nondairy version, go vegan with high-protein options like soy or pea protein–based Greek-style yogurt (e.g., Kite Hill).
Milk: Any unsweetened plant milk works. Soy milk adds more protein, while almond or oat milk gives a lighter feel.

📖 How to Make A Skin Nourishing Watermelon Smoothie

This is an overview. The full instructions are in the recipe card below.

How to cut a watermelon with a sharp knife.

Cut the watermelon (quick-cut trick): Chop the melon in half. Flip the half over so the rind faces up (won’t roll away). Score it both ways like a checkerboard. Pop out the long sticks, chop into cubes, and snack on the extras or store for later. Optional: freeze the cubes for a frostier smoothie.

Pour the nondairy milk into the blender, then add Greek-style yogurt, watermelon cubes (use frozen for a frostier smoothie), flaxseed meal, hemp hearts, chia seeds, and mint.

✔️ Expert Tips

Chia seeds: Let your smoothie sit for 5 minutes after blending—this gives the chia seeds time to thicken the texture naturally, making it creamier without any added ingredients.
No need to grind chia: If you're blending your smoothie, whole chia seeds break down just fine—no grinding needed.
Storage: Refrigerate leftover Skin Nourish Watermelon Smoothie in an airtight jar for up to 2 days.
