Why Do We Need Moisturisers?

The effects of lack of sleep, exposure to smoke, or simply the pass of time and the normal aging process, tend to show on our skin. These show up in the form of unwanted wrinkles, and fine lines. We want to be able to combat them and reverse them!

There are many options available, from over the counter lotions and creams to more expensive solutions prescribed by dermatologists.

Why are moisturisers so important?

The basic function of moisturisers is to keep your skin moist. Moisturisers do this by holding water in the stratum corneum, the outermost layer of the epidermis.

Moisturisers have other functions as well. They can help protect your skin from the environment - applying moisturiser creams or lotions creates a barrier on your skin that keeps oils from escaping and harmful outside elements from coming in and causing dryness and irritation.

There are many moisturisers on the market that are formulated to treat many different skin types, including normal, dry, oily and sensitive skin. People with normal skin need a light moisturiser that contains natural oils, whereas people with dry skin may require heavier lotions with humectants to lock in the moisture. For those with oily skin, there are oil-free, noncomedogenic moisturisers. "Noncomedogenic" is a term applied to oils, lotions, and skin creams that do not block pores. The theory behind using lotions that are noncomedogenic is that by not blocking pores, they will reduce the incidence of pimples.

People with sensitive skin should look for moisturisers that are fragrance-free and contain few ingredients.

Very few moisturisers are able to penetrate deep into the skin layers. The only way they can do that is if its composition features molecules thin enough to able to work their way into the skin.

A lot of the skin moisturisers work by sealing in the moisture of your skin and preventing further loss. In this case, these products don't actually add to the moisture that is already there. At best, they rehydrate the topmost layer of the skin the way water soaks a dry piece of paper. But as for penetrating in to the deeper layers - well, the molecules of these product are often too big to do that, especially if they are oil-based. This is not necessarily a bad thing. In fact, using this type of sort of rehydrating may the best thing for your skin.
