Cell membrane

What is the cell membrane?

The cell membrane is the layer that separates the inside of cells from the outside. That is, it protects the cells from any external agent. Another of its functions is to transport substances into and out of the cell.

What is the cell membrane made of?

  • Glycerophospholipids
  • Molecules composed of glycerol
  • A phosphate group
  • Two chains of lipids, such as fatty acids

What affects the cell membrane?

In addition to age, there are other factors, both external and internal, that can affect the cell membrane and be reflected in the skin.

  • Sun exposure. Too much sun damages our skin. Therefore, we can use moisturizers, anti-inflammatories and antioxidants to reduce the severity of this damage.
  • Stress causes cellular dehydration. Relaxation and enjoyment benefits the whole body.
  • Lack of sleep
  • Dehydration.
  • Diseases.
  • Bad nutrition. Not following a good diet deprives the body of the nutrients needed to produce healthy cells.
  • Chronic inflammation.

For our skin, the cell membrane also retains water and oxygen. It is the basis for healthy skin, because when it is compromised, cells cannot survive.

This causes initial damage to the skin, the first wrinkles and flaccidity appear.

The problem is that cells lose their ability to retain water as the years go by. When we are babies, 75% of our body is made up of water, while when we are over 30 it starts to drop to 50%.

Fortunately, we can take care of the cells that form the skin to boost its hydration and slow down or even reverse the aging process.

From this, we can conclude that hydration or water retention is the key to maintaining healthy skin. and young. This hydration must be supported by fatty acids to strengthen the cell membrane.

Permeabilization of the cell membrane

Transdermal electroporation increases skin permeability by applying short pulses of high voltage.

Mesolux’s RealDeep technology goes a step further by facilitating the introduction of actives of different molecular weights by opening the cell membrane through high-voltage pulses. This allows the active ingredient to enter the skin and act on the target cell.

By increasing the permeability of the skin cell membrane, it is possible to administer actives that will reach deeper into the skin and therefore have a greater effect.

Commitment to quality

This text on the cell membrane has been written by professional editors and reviewed by Sisneo’s medical-aesthetic team. In addition, we have relied on experts in medicine, engineering and aesthetics as a source of information, as well as specific studies to maintain the quality of what we publish.

At Sisneo Bioscience we are committed to publish truthful and contrasted information. And to update or correct it as soon as new knowledge becomes available.
