Buriti Oil
Buriti Oil
Refined Buriti Oil, extracted from the pulp of fruits, is rich in oily acids and high concentration of carotenoids, especially vitamin A, which grant antioxidating, renewing, and regenerating action. Those features are beneficial for the treatment of restauration and hydration of the skin after exposure to sunlight. Buriti Oil can be used on all sort of skins, including delicate ones.
ABOUT BURITI OIL
Origin: Native of the Amazon, Caatinga and Cerrado biomes.
EFFICIENCY EVALUATION
A study has assessed the hydration maintenance of superficial layer of the skin using the Corneometry and TEWL (Transepidermal Water Loss) methods in individuals submitted to topic treatment using Buriti Oil in different concentrations.
The skin is the largest human organ and is divided in three layers: epidermis, dermis, and hypodermis. It is constituted of a barrier responsible for mechanical protection, coating, sensorial functions, and thermal regulation
The stratum corneum is the first layer of the epidermis, formed by cells called corneocytes, which are connected by a complex lipid matrix. This layer is comprised of approximately 10 to 20% water, and the hydration percentage depends on the balance between water supply to the skin and loss through evaporation. The loss of water depends on the quantity of corneocytes layers. This means that the higher the number of layers, the longer it takes for water to pass through, consequently diminishing evaporation.
In addition to natural evaporation, some external factors influence the level of hydration of the skin and the destruction of the protective barrier, such as low atmospheric humidity, pollution, very low temperatures, and the use of abrasive products like, solvents, detergents, excessive use of soap and other chemical compounds. The level of water loss depends on the intensity of the exposition of the skin to those factors. Intense dehydration of the skin favours the depletion of important features such as firmness and elasticity
The usage of hydrating cosmetics can prevent the loss of water by two means:
- Formation of a barrier against superficial evaporation;
- Hydration of the stratum corneum (through the water contained in those formulas, or through absorption of atmospheric water).
IN THIS CONTEXT, EFFICENCY OF THE BURITY OIL WAS PROVEN FOR THE MAINTENANCE OF SKIN HYDRATION AND DIMINISHING LOSS OF TRANSEPIDERMAL WATER.
-
Corneometry
- According to the results, the hydration granted by the BURITI OIL moisturizer samples at 0,5%, 1.5% and 3,0% presented significative difference after 2hrs, 4hrs, 6hrs, and 8hrs of application when compared to the standard. This indicates that BURITI OIL can maintain the skin hydration for at least 8 hours.
- The BURITI OIL moisturizer samples at 0,5%, 1,5%, and 3,0% have significantly increased skin hydration up to approximately 50%, 36%, and 27% respectively, when compared to the standard.
-
 Loss of transepidermal water
- According to the obtained results, it was possible to observe a decrease in transepidermal water loss (TEWL) until 8 hours after the application of the samples at 1,5% and 3,0%, and until 4 hours for the sample containing BURITI OIL at 0,5%. This could be an indicative of the decrease in TEWL due to the formation of a film on the skin.
