Vegetable oils have long been used on the skin for cosmetic and medical purposes because they have been found to have many positive physiological benefits.
Rich in triglycerides, FFAs, tocopherols, sterols, stanols, phospholipids, waxes, squalene, phenolic compounds.
Moisturizers improve skin hydration and viscoelasticity.
EMOLLIENT
Long chain-saturated fatty acids are essential fatty acids examples of emollient. Emollients influence skin physiology and pathology by exerting many effects on skin barrier function, such as eicosanoid production, membrane fluidity, cell signaling, improving skin repair, and permeability, playing an important role for therapeutic benefits.
HUMECTANT
Vegetal oil function as a humectant by improving the skin hydration and increasing the stratum corneum water content. It improves the skin hydration by attracting and binding moisture from the environment if the humidity is more than 70% or draws moisture from deeper dermis to the epidermis.
OCCLUSIVE
Vegetal oil acts as a protective barrier to the skin by an occlusive effect, allowing the skin to retain moisture through creating a hydrophobic barrier over the skin. Therefore, it prevents water evaporation and results in a decrease in the TEWL value from the stratum corneum. It also promotes the desquamation of corneocytes and improves the skin's barrier function.
