Science
Mechanism of Action
It enhances skin barrier function by upregulating epidermal differentiation markers like involucrin and filaggrin, and boosts hydration through increased aquaporin-3 expression and hyaluronan synthesis. Its rich flavonoid content also provides antioxidant benefits and may help reduce melanin production.

Key findings
- 01 Cosmetic preparations containing 1% to 2% aloe extract, including A. arborescens, may offer auxiliary sunburn protection by absorbing UV radiation (max absorption ~294 nm).
- 02 In vitro studies on human keratinocytes show the flower extract upregulates involucrin, filaggrin, and aquaporin expression, along with hyaluronan synthesis, enhancing skin barrier function and protecting against UVB-induced damage.

Formulation
Stability
The extract is generally stable at room temperature (~27°C) but shows instability and color changes (yellow-brown) at higher temperatures (40°C) or alkaline pH due to degradation of active components.
Conflicts
- Alkaline environments (pH > 7.0)
- Strong oxidizing agents
Safety
Safety Profile
The CIR Expert Panel stated in 2020 that data were insufficient to support the safety of Aloe Arborescens flower/leaf extracts, requesting 28-day dermal toxicity studies. For all Aloe species, the industry-established limit for anthraquinone impurities is 50 ppm to avoid phototoxicity.

Verdict
While promising in vitro for hydration, barrier support, and antioxidant effects, more clinical and safety data are needed to fully assess its cosmetic utility and safety profile.
