Structure of facial skin

The skin is made up of 3 layers, according to their depth:

  • the epidermis, the superficial layer
  • the dermis, the intermediate layer
  • the hypodermis, the deepest layer

In cosmetics, the formulas interact with the upper layer of the skin: the epidermis. This layer of the skin which is in contact with the outside is very thin, only a few millimetres, unlike the dermis which is 30 to 40 times thicker. The epidermis has many pores, which allow sebum and sweat to pass through, forming the protective and moisturising film of our skin: the hydrolipidic film, or lipid barrier.

The skin on the body and the skin on the face do not have the same needs. On the one hand, facial skin is more exposed to external aggressions than body skin. In addition, facial skin can be mixed, dry, oily… In order to preserve it for as long as possible from external aggressions, and to slow down the appearance of the signs of ageing, we try to moisturise and protect the epidermis of the face, and therefore to preserve this natural shield which is the lipidic barrier of our skin.

Moreover, the epidermis is a particularly sensitive area for sensoriality, as it contains many nerve endings.

Our ingredients for formulas especially for facial care

Sophim offers natural ingredients that are sensitive to the skin of the face, moisturising, restoring the skin’s lipidic barrier and sensorial.

Our squalane ingredients are ideal for facial care formulas. This is because squalane has biomimetic properties and penetrates our skin very well, as it is derived from squalene, a lipid produced by our body. A highly moisturising emollient with a unique non-greasy feel, squalane is recognised for its properties in restoring the skin’s lipid barrier. As a protective agent, it also contributes to the hydration of facial skin, and helps prevent it from drying out by reducing insensible water loss. Its mineral counterpart, hydrogenated polyisobutene, has similar properties.

Cosmetic vegetable oils and butters are also quality ingredients with benefits for moisturising the face. Generally rich in essential fatty acids, these ingredients are often used in moisturising creams. Depending on the plant origin of the oil or butter, other benefits can be highlighted in the final formula: for example, raspberry oil has a composition richer in antioxidants, ideal for protecting mature skin.

Our range of natural waxes of olive origin bring texture and sensoriality to formulas dedicated to the face.
