See How Moisture Heals Dry Skin with Science

Learn how moisturising can make skin healthy again.

 

This is the top layer of your skin

 

This image represents your skin’s top protective layer, called the Stratum Corneum. It functions like a brick and mortar wall, protecting you from the outside world.

 

• The “bricks” are called corneocytes. These protective skin cells give the skin structure and strength and contain Natural Moisturizing Factor(NMF). NMFs draw in moisture and hold it in the cell.
• The “mortar” is made up of lipids. They form a continuous layer that surrounds the corneocytes – or skin cells (the “bricks”), providing elasticity and flexibility and helping to retain moisture in the skin.

 

Stages on How You Get Dry Skin before Moisturisation

 

1. Stage1

 

When your skin is healthy, it protects you from the elements

 

Skin that is healthy and properly hydrated is naturally capable of defending itself against the causes of dry skin and continuously repairing itself.

 

2. Stage2

 

Then stressors take moisture away from your skin

 

Skin stressors rob your skin of moisture. Such dry skin causes include everyday factors—dry weather, air-conditioning, even showering (during which water and harsh cleansers can wash way away skin’s natural moisturizing factors) can weaken the skin cells and deplete the lipid layer. These factors degrade your skin’s barrier, allowing more moisture to escape.

 

3. Stage3

 

Skin’s protective ability breaks down

 

As your skin gets drier, there’s a breakdown of normal, healthy processes. Without moisture, skin cells become fragile and your lipid layer becomes tighter and less flexible, setting the stage for cracked or damaged skin. As the moisture barrier becomes weakened and damaged, your skin becomes even more vulnerable to the environment, increasing moisture loss.

 

4. Stage4

 

You get dry skin

 

Moisture is lost and skin’s protective defenses are weakened. Skin feels rough and can start to feel itchy. Its natural exfoliation process is disturbed, causing visible flakes to form. Untreated dryness can lead to painful cracking and make the skin more vulnerable to the environment. At a cellular level, corneocyte development is impaired, so skin cells reach the surface underdeveloped and less able to protect against further damage.

 

5. Stage5

 

To recover, replenish lost moisture to heal dry skin

 

A moisturizer will immediately hydrate the skin and soften dry, stiff surface cells. Look for lotions with a combination of humectants, emollients and occlusives. Humectants hold water inside the skin, helping to promote NMF production. Emollients – like stearic acid or triglyceride oils – can replenish the lipid matrix. An occlusive like Vaseline Jelly replaces the lost protective lipid layer, creating a barrier to lock in moisture and protect against the causes of dry skin.

 

6. Stage6

 

Your skin develops healthy cells again

 

Healthy, strong cells grow in. The lipid layer is restored and NMF is produced normally. The natural exfoliation of skin’s top layer begins to occur without interruption.

 

How does moisture heal dry skin?

 

By providing the skin with additional moisture, you can help to restore its natural barrier function. This will reduce the risk of further irritation and keep the skin hydrated and healthy. There are many different types of moisturisers available, so it is important to choose one that is right for your skin type. For example, people with sensitive skin may benefit from using a hypoallergenic moisturizer. Whatever type of moisturizer you use, be sure to apply it regularly throughout the day to keep your skin well- hydrated.
