Aloe Vera for Skin: Possible Benefits, Uses and Safety

Aloe vera is one of the world's best-known plants used in skincare.

The clear gel found inside aloe leaves is included in moisturisers, after-sun products, creams, shampoos and many other cosmetic products.

You may also have seen claims that aloe vera can remove stretch marks, reverse ageing, cure acne, heal eczema, treat psoriasis or rapidly repair damaged skin.

The scientific evidence does not support all of these claims.

Research suggests topical aloe vera gel may have some useful properties, particularly for certain minor skin problems, but evidence varies considerably depending on the condition. NCCIH

It is therefore important to separate what research suggests from what has simply become popular folklore.

What Is Aloe Vera?

Aloe vera is a succulent plant that grows in warm climates and is also commonly grown as a houseplant.

Different parts of the leaf can produce different substances.

The inner portion of the leaf contains the clear gel commonly used in topical skincare products.

A different substance known as aloe latex comes from the outer part of the leaf.

This distinction is important because applying aloe gel to the skin and consuming aloe products by mouth have very different safety considerations. NCCIH

What Is Aloe Vera Gel Used For?

Topical aloe products are commonly marketed for:

• moisturising skin,
• soothing minor irritation,
• after-sun skincare,
• minor burns,
• acne,
• psoriasis,
• wound healing and
• general skincare.

However, being traditionally or commercially used for something does not necessarily prove that it works.

Some applications have been researched much more thoroughly than others.

Can Aloe Vera Moisturise the Skin?

Aloe gel is commonly incorporated into moisturising skincare products.

Some people enjoy its lightweight texture, particularly when they do not want a heavy or greasy cream.

However, aloe vera should not automatically be considered superior to established moisturisers.

People with very dry skin, eczema or another skin disorder may need products specifically designed to protect the skin barrier.

If a product causes burning, itching or redness, stop using it.

Can Aloe Vera Help Burns?

This is one area where research has shown some potential.

NCCIH reports that clinical research suggests topical aloe gel may speed burn healing and reduce burn-related pain. NCCIH

However, we need to interpret this cautiously.

A Cochrane review examining aloe vera for acute and chronic wounds concluded that there was not enough high-quality clinical evidence to establish aloe vera as an effective wound treatment. Cochrane

So we should not tell readers that aloe vera definitely heals burns faster.

More importantly, aloe vera is not a substitute for appropriate first aid or medical treatment for a serious burn.

Aloe Vera Is Not Burn First Aid

If you have just burned your skin, do not immediately cover the injury with aloe vera or another cream.

For appropriate burn first aid, cool the affected area using cool or lukewarm running water for 20 minutes as soon as possible.

Do not use ice, iced water, butter or greasy creams on a fresh burn.

Significant burns and burns affecting certain areas of the body require medical assessment.

Aloe vera should never delay appropriate burn treatment.

What About Sunburn?

Aloe vera is widely associated with after-sun products.

A cool aloe-containing gel may feel soothing on mildly sunburned skin, but that does not mean aloe “repairs” all the skin damage caused by ultraviolet radiation.

Sunburn is evidence that UV radiation has damaged the skin.

The more important strategy is preventing excessive UV exposure in the first place through measures such as appropriate shade, clothing and sunscreen.

Aloe vera should therefore never be marketed as something that makes sun exposure safe.

Can Aloe Vera Treat Acne?

There is some preliminary evidence, but it is limited.

NCCIH reports that two small studies suggested topical aloe gel, when used alongside other treatments, may improve acne. NCCIH

That's very different from saying aloe vera cures acne.

Acne can range from mild to severe, and treatments with much stronger clinical evidence are available.

Persistent, painful, scarring or severe acne should be appropriately assessed rather than relying solely on aloe gel.

Can Aloe Vera Treat Psoriasis?

Some research has investigated aloe vera for psoriasis.

NCCIH describes the available evidence as a small amount of research, rather than established proof of effectiveness. NCCIH

Psoriasis is a chronic inflammatory condition and can require prescription treatment.

People with psoriasis should therefore not discontinue prescribed medicines because they have started using aloe vera.

If you want to try a complementary product alongside treatment, discuss it with an appropriate healthcare professional.

Can Aloe Vera Cure Eczema?

The evidence is not strong enough to say that it can.

NCCIH specifically notes that there is not enough reliable information to determine whether aloe vera is helpful for eczema. NCCIH

This is particularly important because aloe itself can occasionally cause skin reactions.

Eczema treatment often focuses on maintaining the skin barrier with appropriate emollients and controlling inflammation when necessary.

Do not replace prescribed eczema treatment with aloe vera without professional advice.

Does Aloe Vera Remove Stretch Marks?

There is no good basis for promising that aloe vera will remove stretch marks.

Stretch marks are extremely common and can develop when the skin stretches or shrinks relatively quickly.

They may occur during:

• pregnancy,
• puberty,
• periods of rapid growth,
• weight changes and
• other circumstances.

Many creams and oils are marketed as stretch-mark treatments.

A moisturising product may make the skin feel softer, but this is not the same as removing established stretch marks.

Therefore, the claim in the old KandyWandy article that aloe vera gel reduces stretch marks should not be presented as established fact.

Does Aloe Vera Fight Ageing?

This is another claim that needs moderation.

Skin ageing is influenced by numerous factors, including:

• age,
• genetics,
• ultraviolet radiation,
• smoking,
• environmental exposure and
• general health.

A moisturising skincare product can temporarily make dry skin look and feel smoother.

That does not mean it reverses biological ageing.

There is not enough evidence to describe aloe vera as an anti-ageing treatment capable of restoring youthful skin.

For preventing premature skin ageing, protecting the skin from excessive UV exposure and avoiding smoking are much better established strategies.

Can Aloe Vera Heal Cuts?

Do not assume aloe vera should be applied to every cut or wound.

A Cochrane systematic review looked at aloe-derived products for acute and chronic wounds.

The researchers concluded that there was an absence of high-quality clinical trial evidence supporting aloe vera topical agents or dressings for treating acute and chronic wounds. Cochrane

That means the old article's broad statement that aloe helps skin “heal more rapidly” should not be retained as a general fact.

Proper wound care depends on the type and severity of the injury.

Is Aloe Vera Good After Shaving?

Some people use aloe-containing products because they find the cooling gel comfortable after shaving.

However, it should be considered a cosmetic choice rather than a medically necessary aftershave treatment.

If shaving causes repeated cuts, painful irritation, persistent bumps or infection, simply applying aloe may not address the underlying problem.

Using appropriate shaving techniques and suitable skincare products may be more important.

Can Aloe Vera Cause Skin Reactions?

Yes.

“Natural” does not mean a product cannot cause side effects.

NCCIH says topical aloe gel is generally well tolerated, but there have been occasional reports of:

• burning,
• itching,
• rash and
• eczema. NCCIH

Stop using the product if you develop a significant reaction.

If the reaction is severe, persistent or associated with swelling or breathing difficulty, seek appropriate medical help.

Should You Patch Test Aloe Products?

If you have sensitive skin or have reacted to skincare products previously, it can be sensible to try a small amount on a limited area first rather than immediately covering a large area of skin.

Remember that commercial aloe products can contain many ingredients besides aloe vera.

Fragrances, preservatives and other ingredients may sometimes be responsible for irritation.

Read the ingredient list if you have known allergies or sensitivities.

Is Fresh Aloe Straight From the Plant Better?

Not necessarily.

Using a plant directly does not automatically make a treatment safer or more effective.

Aloe leaves contain different substances, and homemade preparation makes it harder to control exactly what is being applied.

Commercial topical products can also vary substantially in composition and aloe concentration.

If you choose an aloe skincare product, use it according to its instructions and avoid assuming that a higher aloe percentage guarantees a medical benefit.

What About Drinking Aloe Vera?

This requires considerably more caution.

Topical aloe gel and aloe products taken by mouth should not be treated as equivalent.

NCCIH reports that oral aloe latex can cause:

• abdominal pain,
• cramps and
• diarrhoea.

Oral aloe leaf extracts have also been associated with cases of acute hepatitis. NCCIH

There are also potential medication interactions.

Aloe Latex Is Particularly Important

Aloe latex is different from the clear inner gel commonly associated with skincare.

NCCIH reports that in the United States, the FDA required manufacturers in 2002 to remove aloe latex from over-the-counter laxative products because manufacturers had not provided the necessary safety data. NCCIH

This is a good example of why “natural” products should not automatically be assumed safe for internal use.

Pregnancy and Breastfeeding

NCCIH advises that aloe—whether gel, latex or whole-leaf extract—may be unsafe when taken by mouth during pregnancy and breastfeeding. NCCIH

Anyone considering oral aloe during pregnancy or breastfeeding should discuss it with an appropriate healthcare professional.

Aloe Vera and Medicines

Herbal products can interact with medicines.

NCCIH specifically recommends that people taking medicines speak with their healthcare provider before using aloe vera or other herbal products because potentially harmful interactions can occur. NCCIH

This becomes particularly important when aloe is being consumed rather than simply used as a cosmetic skin product.

What Aloe Vera Cannot Be Reliably Claimed to Do

Based on current evidence, KandyWandy should not tell readers that aloe vera:

• reverses ageing,
• removes stretch marks,
• cures eczema,
• cures psoriasis,
• cures acne,
• heals every wound,
• instantly repairs sun-damaged skin, or
• guarantees faster healing.

Some of these areas have preliminary research, but preliminary evidence is not the same as a proven treatment.

A Sensible Approach to Aloe Vera

If you enjoy using an aloe-containing skincare product and it does not irritate your skin, it may have a place in your normal skincare routine.

Just keep expectations realistic.

Think of aloe primarily as a topical skincare ingredient with some promising but limited therapeutic evidence, rather than a treatment for dozens of unrelated health problems.

For diagnosed skin diseases, significant burns, infected wounds, persistent rashes or unexplained skin changes, appropriate healthcare assessment is more important than experimenting indefinitely with home remedies.

The Bottom Line

Aloe vera has been used for skincare for generations and remains a common ingredient in cosmetics.

Research suggests topical aloe gel may have some potential for burns and possibly certain other skin conditions, but the evidence is not strong enough to support many of the dramatic claims commonly made about the plant. NCCIH

Topical aloe is generally well tolerated, although some people develop irritation or allergic-type skin reactions.

Oral aloe requires greater caution because different aloe preparations can cause adverse effects and interact with medicines.

So aloe vera can be part of a skincare routine—but it should not be presented as a miracle cure.
