Aloe Vera
INCI · Aloe Barbadensis Leaf Juice · also Aloe, Aloe Barbadensis
How it works
Aloe vera leaf juice is a gel-like extract containing polysaccharides, glycoproteins, and small amounts of vitamins, minerals, and enzymes. The polysaccharide fraction, primarily acemannan, forms a humectant film that hydrates the skin surface and has documented anti-inflammatory activity by inhibiting prostaglandin production. Glycoproteins in the gel are associated with accelerated healing of minor wounds and irritation, and the extract's mild antimicrobial compounds may contribute to its traditional use on minor skin injuries.
The evidence
Clinical studies support aloe vera's role in reducing erythema and inflammation, including in the context of mild sunburn and post-procedure skin. Research on wound healing has shown that aloe-containing preparations can shorten healing time for minor abrasions compared to untreated controls, and some studies report benefits for radiation-induced skin reactions during cancer treatment. Evidence for anti-aging or acne claims is weaker and largely limited to small or industry-funded trials, so aloe is best regarded as a soothing and hydrating agent rather than a corrective active for pigmentation or wrinkles.
Suitability
- Sensitive and reactive skin: reduces redness and calms irritation
- Sun-exposed skin: traditional and evidence-supported after-sun care
- Oily and acne-prone skin: lightweight, non-greasy hydration
- Post-procedure skin: supports comfort during barrier recovery
Concentration
Aloe vera gel is used at concentrations ranging from a few percent as an additive up to 100% in pure leaf gel products. There is no established upper safety limit for topical use, though products made from whole-leaf extract (rather than purified inner-leaf gel) carry a higher risk of latex-related contact irritation due to residual aloin content.
Conflicts & combinations
- Pairs well with panthenol and allantoin for compounded soothing effects
- Commonly combined with centella asiatica in redness-focused formulations
- No known conflicts with acids, retinoids, or vitamin C
- Patch testing is advised for those with a known allergy to plants in the Liliaceae family

Can aloe vera be used on the face daily?
Yes, aloe vera gel is generally safe for daily use, especially on sensitive or sun-exposed skin.
Does aloe vera help acne?
It may reduce redness and inflammation associated with acne, but evidence for treating acne directly is limited.
Is aloe vera good for sunburn?
Yes, it is one of the better-studied soothing agents for mild sunburn and post-sun redness.
Can aloe vera cause an allergic reaction?
Yes, contact allergy is possible, particularly with whole-leaf extracts; patch testing is recommended.
Is pure aloe vera gel better than store-bought products?
Purified inner-leaf gel carries lower allergy risk than whole-leaf extract, which may contain irritating latex compounds.
