10 Amazing Sweet Potato Benefits for Skin You Need to Know

What Makes Sweet Potato A Skin Superfood?

Although they go by the name potatoes, they are not potatoes. Sweet potato is a naturally sweet, starchy root vegetable that is considered highly nutritious. It is a powerful skin superfood that helps boost collagen synthesis, encourage skin cell turnover and protect against environmental damage that contributes to skin ageing. Sweet potatoes come in various varieties, each with a distinct micronutrient profile that benefits the skin in different ways. These include:

• Orange-fleshed: These are the popular ones we often see and are loaded with beta-carotene.
• Purple-fleshed: A purple-fleshed sweet potato is rich in anthocyanins known for antioxidative and antimicrobial properties.
• White-fleshed: A good source of vitamin C, potassium and fibre, white-fleshed sweet potato helps maintain your skin health.

Sweet potatoes help manage conditions such as acne, eczema, hyperpigmentation, and premature ageing, while also providing nutrition and health benefits. Let us learn about the nutritional profile of sweet potatoes in the following section.

Top 10 Skin Benefits of Eating Sweet Potato

Regularly eating sweet potatoes can offer a host of benefits. Here are the top 10 sweet potato benefits for skin:

1. Offers Anti-Ageing Protection

Orange-coloured sweet potatoes are rich in beta-carotene, a potent antioxidant that helps fight against radical damage. Further, it prevents the formation of wrinkles and fine lines. The vitamins C and E in sweet potatoes support collagen synthesis and protect the cell membranes. Consuming sweet potatoes regularly as a part of your diet helps maintain the firmness and elasticity of your skin.

2. Brightens & Evens Skin Tone

Sweet potatoes are rich in vitamin C, which is known to inhibit the pigment responsible for melanin production. Regular intake of vitamin C-rich foods, such as sweet potatoes, helps brighten the skin and reduce the appearance of dark spots, sun-induced hyperpigmentation, and post-inflammatory hyperpigmentation (PIH). Gradually, it gives you an even skin tone.

3. Helps Control Acne

Sweet potato has a low glycaemic index (GI) and is rich in vitamin A. We all know that foods with a high GI spike insulin levels, leading to increased sebum production and acne.

4. Hydrates Skin Deeply

Sweet potato is a hydrating food, with a natural water content of approximately 77%. Consuming it regularly maintains the overall skin moisture from within. Moreover, it contains potassium, which helps maintain cellular fluid balance and keeps the skin plump.

5. Protects From Sun Damage & UV

Purple-coloured sweet potatoes are rich in anthocyanins, which help protect the skin from the sun’s harmful UV rays and prevent damage.

6. Reduces Skin Inflammation

Sweet potatoes contain anti-inflammatory properties that help soothe inflammatory skin conditions.

7. Supports Skin Repair & Wound Healing

Sweet potatoes are a good source of Vitamin A, which helps in cell renewal and wound healing. Regular consumption of sweet potatoes supports faster recovery by promoting the formation of new skin tissue, speeding up the repair of damaged skin barriers, and reducing the formation of scar tissue.

8.  Improves Skin Texture & Smoothness

The Vitamin A, Vitamin C, and manganese present in sweet potatoes help support collagen synthesis, promoting smoother, more refined skin texture.

9.  Reduces Dark Circles & Puffiness

Potassium in sweet potato balances the sodium-potassium equation. This further helps control fluid retention around the under-eye and minimise puffiness. It also contains small amounts of Vitamin K, which can help reduce the appearance of dark circles.
10. Supports the Gut-Skin Axis
Sweet potato is an excellent source of dietary fibre (around 3g/100g) and resistant starch, which helps maintain a healthy gut. This further helps reduce inflammation, improve skin texture, and manage inflammatory skin conditions such as eczema and psoriasis.

Here’s a table that depicts how the key nutrients in sweet potatoes help manage specific skin concerns:

How to Eat Sweet Potato For Maximum Skin Benefits?

How you eat a sweet potato can amplify your skin benefits. Here are the best cooking methods dermatologists usually recommend to maximise the benefits of sweet potato for skin while retaining all its nutrients.

1. Boiling

Boiling sweet potatoes is the way to consume them, especially for individuals with acne-prone skin. Boiled sweet potatoes have a lower GI of approximately 44. On the other hand, a baked sweet potato has a GI of 94 (high).

2. Steaming

Steaming is another preferred way to consume a sweet potato, as it preserves Vitamin C and most of the B vitamins. Steaming a purple variant helps retain more anthocyanins.

3. Roasting with Healthy Fats

For a little yummiest taste, roast a sweet potato with healthy fats like cold-pressed olive oil or coconut oil. You can even pair it with avocado. This way, the absorption of beta-carotene from the sweet potato will be the maximum.

4. Eating with Skin

Can you eat a sweet potato with the skin? Well, absolutely yes. Eating a sweet potato without peeling helps with the much-needed antioxidants such as chlorogenic acid and carotenoids. Make sure you wash the skin thoroughly before consuming it.

What Is The Recommended Daily Intake?

How much sweet potato should one eat to reap its benefits? Always consume a sweet potato in the required quantity as recommended by your dermatologist or nutritionist. Half of a medium-sized sweet potato (with skin) contains about 100-150 g, which is generally the suggested intake.
