How does Moisturiser Work?

After seeing so so many beauty blogs reviewing so many different kinds of moisturiser, I couldn’t help but wonder how does moisturiser work?

Those of you who have followed this blog for some time know that I love doing kind of sciencey-things-made-fun posts. If you have any ideas for posts, please let me know in the comments!!

As for moisturiser, it’s one of the few beauty products I use. Moisturiser and eye liner is pretty much my whole morning routine.

WHAT

Your skin has three layers: the epidermis, dermis, and a layer of fat. The top layer, the epidermis is usually made of 15% water and when it falls to around 10%, your skin starts to fell dry.

We all know what that feels like: yucky.

Drying out sometimes happens when you use strong soaps that reach down deep and clean out stuff. That’s a good thing but they sometimes take too much water and good oil with them, leaving skin dry.

Drying out can also happen when your skin sheds cells too quickly and in white flakes.

This is when the question of how does moisturiser work comes in.


 

HOW

Moisturiser is basically drops of oil suspended in water and held together with stabilisers (doesn’t that make it sound cool?!). It both restores oil and water in skin and also helps regulate cell turnover (that’s why its important to keep using moisturiser).

Now-a-days, a bunch of other things are often added to moisturisers. From anti-oxidants for anti-ageing to UV-protection, moisturiser has started doing so much more than just, well, moisturising.

There are generally three things in moisturisers that all work in different ways.

Humectants absorb moisture from the air and hold it (sounds like sorcery right?!).

Emollients fill the spaces between cells to smooth skin.

Preservatives, well, preserve the moisturiser.

It’s pretty easy to find a moisturiser for just about anything. Depending on the additives, they can be used for:

+ anti-ageing
+ sun protection
+ evening skin tone
+ clearing acne & blemishes
+ foundation (gotta love a good BB or CC cream)
+ making skin look less shiny

… and oodles of others along with combinations of all the above.

 

So clearly, how moisturiser works isn’t a simple answer but it’s definitely still one of my favourite products.
