What is in our Moisturiser?

Everywhere we go or look, we see moisturise this, moisturise that. We go into the store and we grab a moisturiser because it says so on the package but what exactly is in our moisturisers?? What substance is the reason our face stays moisturised?

I have created a reasonable amount of words to read with so much value to leave you

The main goal of moisturisers is to attract moisture from the air and hold water in the outermost layer of your skin, but moisturisers can also serve as a barrier to protect that layer from damage. The groups of ingredients that help moisturisers accomplish these goals are occlusive, humectants and emollients.

Occlusive ingredients block TEWL by forming a hydrophobic film on the skin surface. Transepidermal water loss (TEWL) is the amount of water that passively evaporates through skin to the external environment due to water vapor pressure gradient on both sides of the skin barrier.

Some occlusive ingredients include:

  • Beeswax
  • Cetyl alcohol
  • Cocoa butter
  • Dimethicone
  • Glyceryl stearate
  • Grape seed oil
  • Lanolin
  • Lecithin
  • Petrolatum
  • Mineral oil
  • Squalene

Humectants take moisture from the air and hold it in your skin. They also pull water from the dermis (second layer of the skin) to the epidermis (top layer of the skin) and bond with the water molecules.

Some humectant ingredients include:

  • Glycerin
  • Butylene glycol
  • Honey
  • Sorbitol
  • Hyaluronic acid
  • Jojoba oil
  • Aloe vera
  • Lactic acid
  • Glycolic acid
  • Urea
  • Sodium Lactate

Emollients fill in tiny gaps where the skin may be flaked or cracked. They use the moisture collected by humectants to do their job.

List of Emollients that are safe to use:

  • Shea butter
  • Mango butter
  • Cocoa butter
  • Dimethicone
  • Cyclomethicone
  • Almond oil
  • Avocado oil
  • Cyclopentasiloxane
  • Glyceryl stearate
  • Olive oil
  • Lanolin oil
  • Isohexadecane
  • Beeswax
  • Cosmetics-grade mineral oil
  • Cosmetics-grade petrolatum
The Three Parts of a Moisturiser

In conclusion, moisturisers are used to do three things to the skin; draw water from the air and bond with water on the skin. This is done by the humectants. Secondly, it forms a layer on the skin to prevent water loss/evaporation from the skin, this is done by occlusive ingredients in the moisturisers and lastly, the emollients fill in the dry and flaky gaps in the skin with the moisture collected by humectants.

Hope this gives you an insight of why everyone says moisturise.
