What it is
Aloe Barbadensis Leaf Extract is derived from the leaves of the aloe vera plant, a stemless succulent with thick, fleshy, serrated leaves. In cosmetic use it is typically prepared as a hydroglycolic extract, though oil-based versions exist for the leaf's lipid fraction. The inner-leaf gel is rich in water-binding polysaccharides such as acemannan, and the extract is valued for moisturizing, emollient and skin-soothing properties broadly similar to those of aloe juice. In sunscreens it contributes a light, hydrating, conditioning feel rather than any sun-protective action.
Safety & warnings
Aloe vera is generally well tolerated topically, and purified, well-characterized cosmetic-grade aloe is considered suitable even for many people with sensitive skin. Allergic contact dermatitis does occur but is uncommon; reported reactions can include itching, redness or rash. Raw or unrefined aloe and aloe latex can contain anthraquinones such as aloin, which is regarded as a potential sensitizer, so refined cosmetic extracts with controlled impurity levels are preferred. People with a history of plant or cosmetic reactions may wish to patch test a new product first.
Origin & sourcing
It is a botanical ingredient sourced from Aloe vera (Aloe barbadensis), a succulent considered native to the southeastern Arabian Peninsula, particularly the Hajar Mountains of northeastern Oman and the eastern United Arab Emirates. The plant has since naturalized across North Africa, the Canary Islands and Mediterranean regions, and is grown commercially in countries including Mexico, India, the United States, Spain and South Africa, with much of the harvest directed to the cosmetics industry. The clear inner-leaf gel, which has a pH of roughly 4.4 to 4.7, is the part most commonly used.
History
Aloe vera has a long record of cultivation: the species was introduced to China and parts of southern Europe in the 17th century, and large-scale commercial production developed across multiple continents, much of it oriented toward cosmetic use. The leaves contain acemannan gel used topically alongside aloin, a bitter compound associated with the leaf latex.
Questions everyone asks
Does aloe vera in sunscreen provide UV protection?
No. Aloe Barbadensis Leaf Extract is a soothing, hydrating conditioning ingredient and is not a UV filter; the sun protection comes from the actual filters in the formula.
Is aloe extract good for sensitive skin?
Aloe is generally well tolerated, and purified cosmetic-grade aloe is often suitable for sensitive skin. Allergy is possible but uncommon, so a patch test is sensible if you react easily.
What does aloe extract do in a sunscreen?
It binds water and conditions the skin, giving a light, hydrating, soothing feel; it shares moisturizing, emollient and soothing properties broadly similar to aloe juice.
