Answer
Mixing two finished cosmetic formulations like a body lotion and an aloe gel base is generally not recommended. Each formulation is designed with a specific balance of ingredients, pH, and stability. Combining them can lead to unpredictable results, such as:
- Instability (separation, change in texture)
- Reduced effectiveness of active ingredients
- Compromised preservation, potentially leading to bacterial growth
- Skin irritation or other adverse reactions
It is best to use each formulation separately as intended or to create a new formulation from individual ingredients if you wish to combine the benefits of certain components.
