Aloe Vera for Skin: Benefits, Limits & Safety

Aloe vera has a long history in personal care, and aloe gel is widely used in soothing and moisturizing formulas. But aloe has also accumulated a long list of exaggerated internet claims—from “detoxing” the body to curing digestive, immune and skin diseases.

The evidence is much more modest. Topical aloe and oral aloe should not be treated as the same thing.

What topical aloe can do

In a well-formulated cosmetic, aloe can contribute to a lightweight, soothing and hydrating skin feel. Topical aloe gel is generally well tolerated, although occasional burning, itching, rash and eczema have been reported.

What aloe cannot be assumed to do

A cosmetic aloe product should not be expected to cure eczema or psoriasis, eliminate acne, balance your body’s pH, cure asthma or allergies, treat infections, prevent heart disease or produce weight loss. Those are medical claims that require a very different level of evidence.

Is drinking aloe the same as applying it?

No. Aloe products taken by mouth have different safety considerations. The National Center for Complementary and Integrative Health notes that oral aloe latex can cause abdominal pain, cramps and diarrhea, and certain aloe leaf extracts have been associated with liver injury. Aloe can also interact with medications.

People who are pregnant or breastfeeding should consult a healthcare professional before taking aloe by mouth.

How to use topical aloe more safely

• Patch test if you have reactive skin or a history of plant allergies.
• Stop if you develop persistent burning, itching or rash.
• Do not use a cosmetic as a substitute for medical treatment of an infected, blistered or severe skin condition.
• For sunburn, cool the skin, protect it from further sun exposure and seek care for extensive blistering or systemic symptoms.

Bottom line

Aloe can be a pleasant, useful cosmetic ingredient for hydration and a soothing skin feel. It is not a cure-all, and oral aloe deserves considerably more caution than a topical cosmetic.
