Parched, dry skin, that feels like it is one size to small.
This is often referred to in dermatology as a lipid, dry skin.
It characteristically has small pores, which secrete only a minimal amount of oil (sebum).
ROLE OF MOISTURIZERS
Moisturizers Ingredients will vary, depending on the type of skin the formula is for.
The best moisturizer for a dry skin usually contains protective ingredients, such as emollients, which help to keep the barrier function intact.
However, a formula for an oily skin, should ideally contain ingredients that help to slow the flow of oil from the sebaceous glands.
Likewise, a formula for blemishes, should contain anti-bacterial and anti-microbial ingredients.
DRY OR DEHYDRATED?
There is often confusion around the role of humectants and moisturizing ingredients in skin care.
So I want to take a moment to review these two formulas:
BEST MOISTURIZER FOR DRY SKIN
The best moisturizers for a dry skin creates an occlusive film, this is what improves the texture, giving the skin its soft, smooth feel.
Many occlusive ingredients help create a barrier on the skin, repairing and protecting the skin from environmental conditions.
The best moisturizer for dry skin, should contain emollient ingredients.
Emollients help to keep the surface lubricated and protected, they include ingredients such as Silicones, Shea and Cocoa butter.
Lipids have a protective role on the skin, helping to improve the barrier function, they patch up gaps between the cell walls.
Some of the best moisturizers contain lipid ingredients; these include Phospholipids, Sphingolipids or Glycosphingolipids, which are more commonly known as Ceramides, Cholesterol and Fatty Acids.
BEST MOISTURIZER FOR DEHYDRATED SKIN
This is where the confusion comes in.
A dry skin is a skin type and lacks oil, therefore the above ingredients are going to be perfect.
However a dehydrated skin is a condition that lacks moisture, this is something I discuss further in the article the clear skin difference.
If you have dry skin then I have three little words to say to you, hydration, hydration, hydration, and humectants are going to be your new best friend, because dehydrated skin loses its ability to hold water.
The main role of humectants is to form hydrogen bonds that contain molecules of water, essentially they are substances that are designed to absorb water from the air.
