What is aloe vera?

Aloe vera is a green, cactus-like plant that belongs to the lily family. Renowned since ancient times for its medicinal uses, it thrives in hot, dry climates, and is cultivated in subtropical regions across the globe. With its long, thick, juicy leaves, containing gel-like, water-filled tissue, it has a host of health-promoting nutrients, including vitamins, minerals, amino acids, and antioxidants.

It is celebrated for its anti-inflammatory properties, powerful effects on skin health and success in treating various ailments. While you can extract the gel directly from the plant, shop-bought aloe vera products are also widely available.

There are a long list of aloe vera-based options to choose from:

• Raw: Raw aloe vera is extracted directly from the gel inside the plant.

• Ointment, gels and lotions: These are for external use and may include additional ingredients.

• Skincare products: Many moisturisers, cleansers, or shampoos contain aloe vera. They may also include additional ingredients for a pleasant smell or to extend their shelf life.

• Supplements: These are usually found in capsule or powder form.

• Drinks: Aloe vera juice is made from the gel inside the leaves - it's often diluted with water or fruit juice to improve the taste.

Dr Hannah Kopelman is a dermatologist specialising in skincare and hair loss. She is also host of the Derm Club podcast.

Kopelman explains that one of the primary benefits of aloe vera is its ability to hydrate your skin without leaving it greasy, making it suitable for all skin types, including oily and acne-prone skin.

She says: "It contains polysaccharides that help retain moisture in your skin, as well as antioxidants, vitamins A, C, and E, which protect the skin from free radical damage and support its natural healing processes."

How is aloe vera good for your skin?

Although it is made up of 99% water, aloe vera is rich in skin-boosting ingredients. Its mix of vitamins, minerals, and enzymes makes it a powerful topical treatment for skin health.

الفيتامينات والمعادن

Aloe vera contains vitamins such as A, C, and E that help fight off damage in your body, along with other vitamins - for example, B12, folic acid, and choline. It also has minerals such as calcium, magnesium, and potassium.

Sugars

The simple sugars in aloe vera (fructose and glucose) boost cell energy, while the complex sugars (glucomannans/polymannose) help hydrate your skin.

Enzymes

Enzymes are proteins that accelerate chemical reactions in your body. The enzymes in aloe vera help calm irritated skin.

Saponins

Saponins act like natural soap, keeping things clean and germ-free.

Fatty acids

Aloe vera is a source of healthy fats (cholesterol, campesterol, β-sitosterol, lupeol) that have inflammatory and antiseptic properties.

Lignin

This is a molecule that helps creams and lotions deliver their ingredients deeper into your skin.

Auxins and gibberellins

These plant hormones can speed up wound healing and soothe irritation.

حمض الساليسيليك

Aloe vera contains salicylic acid that possesses anti-inflammatory and antibacterial properties.

Inflammation relief

Aloe vera, with its natural anti-inflammatory properties, may help soothe inflammation from skin conditions such as eczema and psoriasis. It can also help calm red and inflamed acne.

Healing support

For minor wounds such as cuts, scrapes, and burns, aloe vera can speed up the healing process. This is because it helps new skin cells grow faster and soothes inflammation.

According to Kopelman, aloe vera can assist in wound healing and minimise the appearance of scars.

She says: "Its growth hormones - gibberellins, and polysaccharides - stimulate the growth of new cells. This helps in the repair of damaged skin and speeds up the healing process."

Skin elasticity

Aloe vera hydrates dry skin and reduces the appearance of wrinkles by encouraging collagen and elastin production. It also helps your skin to shed dead cells, which makes your skin feel smoother.

"Regular use of aloe vera can also help improve skin texture and reduce the appearance of fine lines and wrinkles, thanks to its ability to boost collagen production and improve skin elasticity," Kopelman explains.

Germ fighting

Aloe vera can also fight off infections caused by fungus, bacteria, and viruses.

Is drinking aloe vera good for your skin?

Drinking aloe vera offers fewer health advantages than applying it to your skin. Though oral consumption of aloe vera is linked with various wellness benefits, strong scientific evidence is still developing. Studies suggest aloe vera may be effective in fighting inflammation and that it may improve heart health, aid digestion, and maintain healthy blood sugar levels, cholesterol, and weight.

However, several studies state that taking aloe vera juice orally may have harmful side effects on your body such as:

• غثيان.

• التقيؤ.

• الإسهال.

• Stomach pains.

• Liver inflammation (hepatitis).

• الإمساك.

The laxative effects of aloe vera can also flush out electrolytes, such as potassium, which are important for your body's functions.

Although aloe vera juice boasts potential health benefits, research on its safety for drinking is limited. Given the wealth of studies supporting its topical use, it's best to only apply aloe vera directly onto your skin. This might be a safer option until more conclusive research on oral consumption is available.
