Uses and Benefits of Aloe

Aloe is a family of plants with medicinal properties. Aloe can be applied topically (to the skin) or taken orally (by mouth) to help prevent and heal certain health conditions, such as acne and burns.12

Aloe vera is the most common type in aloe-based products. It originates from the cactus-like Aloe barbadensis Miller plant.3 Research has found that the active compounds in aloe vera may help protect bones and prevent conditions like cancer and diabetes.4

Aloe is generally safe, but negative reactions, including allergic reactions and aloe poisoning, can occur. It can also trigger skin conditions like eczema.

Types of Aloe and Their Uses

There are over 500 species of aloe, which all have different characteristics and uses.5 Some of the more common types of aloe used in medicines and topical products include Aloe vera and Aloe arborescens.15

Aloe Vera (Aloe Barbadensis Miller)

Aloe vera originates from the Aloe barbadensis Miller plant, which contains over 200 bioactive compounds that support health. Most of these compounds reside in the inner clear gel of its leaves.6

Aloe vera is used in medicines and skincare products—often in gels and creams.4 It has shown moisturizing and wound-healing properties when applied directly to the skin.7 Its healthful compounds include polysaccharides, flavonoids, amino acids, and phenolic acids:6

Polysaccharides: Carbohydrate molecules that provide energy to plant cells. Some materials used for wound healing and medicines are derived from the polysaccharides in Aloe vera.8

Liu C, Cui Y, Pi F, Cheng Y, Guo Y, Qian H. Extraction, purification, structural characteristics, biological activities and pharmacological applications of Acemannan, a polysaccharide from Aloe vera: A review. Molecules. 2019;24(8):1554. doi:10.3390/molecules24081554

Flavonoids: Natural plant substances that contain anticancer, antioxidant, anti-inflammatory, and anti-viral properties. These substances have also been shown to protect the heart and brain.9

Amino acids: The basic building blocks of proteins. Amino acids perform many functions, including helping the body break down food and repairing body tissue. They also act as a source of energy for the body.10

Phenolic acids: Natural antioxidants that reduce the risk of oxidative stress in the body. A buildup of oxidative stress in the body can eventually lead to diseases such as cancer, heart disease, and diabetes.11

When applied to the skin, aloe might reduce symptoms of conditions like acne and burns.2

Aloe consumed orally has been shown to help with weight loss, cancer, diabetes, hepatitis (liver inflammation), and inflammatory bowel disease, or IBD (conditions that involve long-lasting inflammation of the digestive tract).42

Certain Aloe vera compounds, including aloin, may help protect the bones and slow the progression of bone diseases such as osteoporosis (bone loss). While research is promising, more clinical trials are needed to determine how Aloe vera and its compounds protect the body from certain conditions.4

Aloe Arborescens

Aloe arborescens has shown antioxidant effects in clinical studies.12 Antioxidants are compounds that inhibit the growth of free radicals—molecules that can harm the body’s cells. However, most research focuses on Aloe vera.12

Aloe arborescens contains a higher concentration of fatty acids than Aloe ferox or Aloe vera. These fatty acids efficiently coat the plant and act as a barrier to environmental stressors.12 They include linoleic acid and linolenic acid, which are polyunsaturated, omega-6 fatty acids considered essential fats (fats our bodies cannot produce on their own).1314

Polyunsaturated fats are a type of healthy fat needed for brain health and for the body’s cells to function properly. Omega-6 fatty acids help with cell function.1314

Aloe Ferox

Aloe ferox is one of the most widely used medicinal plants. It has shown promise in reducing body weight, body mass index (BMI), low-density lipoprotein (LDL) cholesterol, and fasting blood glucose (FBG). Research shows these health benefits may be driven by certain compounds found in aloe ferox that naturally detoxify and act as a natural laxative to promote bowel movements.15

Other studies show that Aloe ferox has antioxidant, antimicrobial, and anti-cancer properties.16

Further studies on aloe ferox are needed on safety and efficacy, as the plant can only be used for limited periods due to side effects.15

Aloe Perryi

Aloe perryi is an herb that has shown antioxidant, antibacterial, and anti-cancer effects in clinical studies.1718 Extracts are used in medicines to treat many conditions, including cancer. Research is still determining the most effective way to administer it.18

Aloe perryi contains many phytochemicals (plant chemicals) that help fight disease. These include flavonoids and other compounds, including:18

Glycosides: Plant-derived compounds of one or more sugars that combine with a hydroxy compound (a compound of one oxygen atom chemically bonded to one hydrogen atom). Glycosides have shown anti-inflammatory and antioxidant activities that help with disease prevention and management.19

Proteins: Complex molecules that play many roles in the body. They are required for the function, structure, and regulation of the body’s tissues and organs. Proteins contain amino acids, which help the body digest food, repair body tissue, and produce energy.20

Phenols: Antioxidants with anti-inflammatory actions that help prevent the buildup of oxidative stress in the body that can lead to chronic (long-lasting) conditions like diabetes, cancer, and heart disease.21

The flowers of Aloe perryi have been studied for their rich phytochemical content, which might help prevent the growth of cancer cells.22

How To Use

Aloe dosages depend on the type and usage. While aloe has been used as a laxative in juices and other consumable products, it is no longer approved for this use by the U.S. Food and Drug Administration (FDA) because of a lack of safety data.3

Aloe vera gel can be applied to the skin as an ointment to speed up wound and burn healing, or to help treat acne.322Aloe vera is also found in drinks, capsules, powders, and food flavorings (as an additive).3

Aloe arborescens can be consumed as a juice or applied as a gel. The dosage varies depending on the condition being treated.2312

Aloe ferox can be consumed as a supplement.15 One study provided participants with two capsules per day at a dosage of 460 milligrams (mg) for two weeks, followed by a 2-week break. This cycle was repeated three times. After three months, participants saw significant improvements in body weight, body mass index (BMI), low-density lipoprotein cholesterol (LDLc), and fasting blood glucose (FBG).15

Extracts of Aloe perryi are used in medicinal settings for wound healing and to treat conditions like cancer.18 A healthcare provider administers the medication and treatment.

Always discuss dosages and uses of aloe with your healthcare provider before adding it to your routine.

Safety and Side Effects

When consumed by mouth or applied to skin correctly, aloe is safe and well-tolerated.2 However, people who are pregnant should avoid taking it.2 Other risks include aloe poisoning and allergic reactions.

Aloe Poisoning

Aloe poisoning can occur if certain preparations (such as in the form of whole leaf extract, latex, or gels) are swallowed.24 Symptoms of aloe poisoning include:25

Severe abdominal pain

Vision loss

Difficulty breathing

Diarrhea

Rash

Swelling of the throat

Vomiting

Skin irritation

Call your local emergency number or a local Poison Control Center if you experience any of the above symptoms after using aloe. You can also call the national toll-free Poison Control hotline at 1-800-222-1222. Get medical help right away if you think you have aloe poisoning.25

Aloe Allergy

Some people are allergic to aloe. Symptoms of an aloe allergy include:25

Chest pain

Tightness in the throat

Rash

Breathing difficulty

Other Side Effects

Other side effects include skin reactions, gastrointestinal (digestive) reactions, and acute hepatitis. For example:2

Topical use of aloe gel may cause burning, eczema, and itching (pruritus). If this happens, discontinue use and speak to your healthcare provider.

Oral use of aloe latex may cause cramping or abdominal pain.

Consuming aloe leaf extracts between periods of anywhere from three weeks to five years has been associated with cases of acute hepatitis.

Choosing An Aloe Product

When selecting an aloe product, factors to consider include the intended use, whether it is taken orally or applied topically, and the type of aloe.

Supplements are not regulated by the FDA, but the FDA has approved Aloe vera as a food additive for flavor.263 If taking an aloe supplement, check the label to see if it is third-party tested. This means the product has been tested for quality and only contains the ingredients listed on the bottle.27

When choosing aloe-based creams or gels, opt for ones made from whole-leaf extracts that have been decolorized. Whole-leaf extracts of aloe vera that have not been properly processed have been linked to cancer.28

Speak to a healthcare provider if you are unsure which type of aloe is right for you. Always take aloe products as prescribed or instructed on the product package.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
