The stratum corneum is the differentiated part of the epidermis, as it contains a thick layer of keratin and lipids that form an efficient barrier, selectively regulating water permeability. This barrier is rich in essential fatty acids, such as linoleic (Omega 6), linolenic (Omega 3), and arachidonic acids. These are located between the keratinocytes, constituting a true barrier to skin absorption.
The lack of these essential fatty acids causes several changes and mainly disorganization in the keratinization process, favoring an increase in transepidermal water loss (TEWL) resulting in rough, xerotic, opaque, and scaly skin. The restoration of skin hydration occurs due to the increase in superficial humidity, the diffusion of dermis-epidermis water, the production of intracellular lipids in the epidermis, and the restoration of the barrier function of the epidermis.
Developed by Vevy, Efaderma® is an active ingredient composed of a rich association of essential fatty acids, such as linoleic, linolenic, and arachidonic acid, identical to those found in our skin, capable of restoring physiological balance, restoring the barrier function of the stratum corneum, reducing transepidermal water loss (TEWL) and reestablish the skin's natural hydration conditions.
Efaderma® is an emollient with high moisturizing potential. Restoring the barrier function of the epidermis reduces transepidermal water loss, modulates the function of the sebaceous glands, and helps with the permeability of active ingredients due to its affinity with the skin. It is an ideal ingredient for skin, hair, and nail care applications. It is also recommended in cases of hyperkeratosis.Active ingredients (or INCI)
