Your skin is like a house plant: skin moisture barrier

Your skin is made up of three primary layers – the epidermis (top layer), dermis (middle layer) and subcutaneous tissue (bottom layer). But your moisture barrier comes into play on the outermost layer of your epidermis, known as the stratum corneum. This layer comprises a wall of cells containing oils and fats that act as a layer of protection from bacteria, irritants and environmental aggressors (a.k.a pollution and UV damage). This layer also sheds dead cells when we exfoliate our skin and is strengthened with electrolytes and nutrients to prevent water and moisture loss (preventing dryness and dehydration).

Why is it so important:

Your moisture barrier is vital to help the skin remain supple, plump and hydrated.

Your moisture barrier is made up of fats like butter to put in a very simple way without getting too scientific. Like butter in a sandwich it holds skin cells together to prevent cracks or gaps from forming on the skin. So when your moisture barrier functions properly it can draw in moisture effectively and defend itself.

Infact the skin's barrier is considered by many experts to be the cornerstone of the entire healthy skin equation. Meaning if you understand yours, you'll have a much easier time avoiding common skin concerns from acne to dullness.

Most issues we have with our skin is due to a skin barrier that becomes compromised.

However there is a lack of education on this although its been said to be the '101 of esthetician school'.

You may be wondering why the title' your skin is a houseplant'. Imagine your skin is a plant, says Dr Bhatti New York based dermatologist., the leaves are nice and soft and everything is great. But if you stop watering the plant, or the heat is turned up or in very hot climates the house will tend to get really hot during the day.

It then becomes too dry and there is not enough humidity, the leaves turn dry, they crack and become brittle.

That is what happens to the skin barrier if you're not caring to the hydration; the skin reacts to the environment, because it has no protection. if you keep the barrier controlled, hydrated, its going to feel like that smooth, soft leaf.

The to Improving your skin barrier depends on if your skin is dry or oily. If your are an oily skin then you cannot be splurging on Vaseline or Aquaphor it will clog pores. It doesn't add to hydration it just helps to occlude the pores to prevent moisture loss. Thus if your have acne prone skin, slugging on these products is probably not for you.

If you have dry skin or eczema then this method may help.

So you don't need to do this if you have normal to oily skin as this may cause breakouts by blocking pores and causing irritation.
