Aloe extract is a substance derived from the leaves of the Aloe vera plant (and related species). It's a widely used ingredient in cosmetics, skincare, and health products, renowned for its soothing, moisturizing, and potential healing properties. The extract can be made from different parts of the leaf, leading to two primary forms with very different uses and safety profiles.

1. Source and Types of Extract

The Aloe vera leaf consists of three main layers:

Green Rind (Outer Skin): Protective and bitter.
Latex (Yellowish Sap): A layer just beneath the rind.
Gel (Inner Leaf Pulp): The clear, mucilaginous, and water-rich core.

The type of "aloe extract" depends on which part is processed:

Extract Type	Source	Primary Use & Properties
Aloe Vera Gel	Inner Leaf Pulp	Topical (on skin): Soothing, moisturizing, cooling. Oral: As a dietary supplement.
Aloe Latex	Yellowish Sap	Oral (historically): A powerful laxative due to compounds called anthraquinones. Note: This form is now heavily restricted or banned in many countries due to safety concerns.

When you see "aloe extract" in most modern lotions, creams, or gels, it typically refers to the inner leaf gel.

2. Key Components and How They Work

The benefits of aloe gel extract are attributed to its complex chemical composition, which includes:

Water (~99%): Makes it an excellent hydrator.
Polysaccharides (especially Acemannan): These long-chain sugars are believed to be the primary active compounds. They have moisturizing, anti-inflammatory, and immune-modulating effects.
Amino Acids: Building blocks for skin repair.
Antioxidants (Vitamins C, E): Help protect the skin from free radical damage.
Enzymes & Salicylic Acid: Have mild anti-inflammatory and exfoliating properties.

3. Common Uses and Purported Benefits

Topical Application (On the Skin)

This is the most common and well-supported use.

Soothing Sunburns and Minor Burns: Aloe's cooling effect and anti-inflammatory properties provide immediate relief and are thought to promote healing. It is a staple in after-sun products.
Moisturizing Skin: Its lightweight, non-greasy texture hydrates without clogging pores.
Supporting Wound Healing: Some studies suggest it can accelerate the healing of minor cuts and abrasions by improving blood flow and reducing inflammation.
General Skin Conditions: Used to soothe skin affected by psoriasis, eczema, and acne due to its anti-inflammatory properties.

Oral Consumption (As a Supplement)

Aloe vera juice or capsules (made from the filtered or decolorized inner leaf gel to remove laxative compounds) are marketed for:

Digestive Health: Claimed to soothe the digestive tract.
Antioxidant Support: To combat oxidative stress.
Note: The scientific evidence for oral benefits is much weaker than for topical use, and safety is a greater concern.

4. Important Safety Considerations

Topical Use: Generally very safe for most people. A patch test is recommended for those with sensitive skin, as rare allergic reactions can occur.
Oral Use (Aloe Gel): Considered possibly safe when the laxative compounds (anthraquinones) have been removed. However, it can cause stomach cramps or diarrhea in some individuals.
Oral Use (Aloe Latex): UNSAFE. The anthraquinones are strong irritants to the digestive tract. Long-term use has been linked to serious issues, including electrolyte imbalance, kidney problems, and potential carcinogenicity. Its use as a laxative is banned by the FDA in the U.S.

Summary

In essence, aloe extract—specifically from the inner leaf gel—is a valuable natural ingredient prized for its ability to soothe, cool, and hydrate the skin. Its effectiveness in treating sunburns and moisturizing is well-established. However, it is crucial to distinguish between the safe topical gel and the hazardous latex, especially when considering oral consumption.
