The skin has remarkable properties of protection and defense against external aggressions, so it is very important that its health is permanently maintained. The main purpose of this research paper consisted in the formulation of two moisturizing creams based only on natural ingredients. The main ingredients were: fresh lavender flowers, aloe vera gel and coconut butter. The moisturisers were organoleptically, physicochemically and microbiologically analysed. The organoleptic tests showed that the moisturizing creams homogenized very well, did not show phase separations and the smell was very pleasant, specific to lavender. The pH values, between 5.0 and 5.3, were close to the optimal recommended, 5.5, which means that their use will have positive effects on the skin. Following the determination of the acidity index, values between 1.68 and 1.91 were obtained, which means that the products can be used safely, as they have not undergone alteration processes. Microbiological analyses showed low contamination with bacteria and fungi, as both lavender and aloe vera are known for their antibacterial and antifungal effects.
