Skin Structure and Cell functions

SKIN  FUNCTION AND STRUCTURE:

Micronedling has been popular procedure since early 90’s. It was developed and used by Dr. Desmond Fernandes to treat wrinkles and scars with hypodermic needles.

Microneedling increases the production of collagen and other healing factors by causing trauma to the skin. 

When the skin ages its decreasing collagen production which is contributing to wrinkles and other signs of aging.

Skin can also lose collagen due to injuries such as acne scarring, stretch marks or other scars.

It is important to know that doing microneedling procedure is not a quick fix. 

It takes at least 3 sessions or more to see the desired results.

Our clients are usually come to us for these particular issues: hyperpigmentation, wrinkles, dry skin and loose skin.

In order to help to resolve these problems, we need to regulate cell function.

The 3 key cells to focus on in order to restore healthy and younger looking skin are:

• Keratinocytes
• Melanocytes
• Fibroblasts

There are 3 functions of skin is to barrier defence, provides pigment for UV protection and provide strength and elasticity. The main function of the skin is to act as a barrier. 

Many skin problems can be seen on the outside and many problems may be laying on the deeper layers of the skin.

The first three layers of skin marrier defence are:

• Acid mantle – The acid mantle is the skin’s way to protect itself from bacteria, environmental pollutants, and moisture loss. The acid mantle is made up of natural oils, sweat, and dead skin cells, and is slightly more acidic in nature to prevent these harmful (naturally alkaline) contaminants from penetrating and damaging the skin.

• Corneocytes – are terminally differentiated keratinocytes and compose most if not all of the stratum corneum, the outermost part of the epidermis. They are regularly replaced through desquamation and renewal from lower epidermal layers, making them an essential part of the skin barrier property.

• Lipid bilayers – is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.

Dermis composed of 2 layers
The pepilary dermis – which is superficial zone beneith the dermis with thin, delicate colagen fibers and is highly vasculanized.

The reticular dermis – is composes the bulk of the dermis, is less vascular and demonstrates thick well organized collagen bundles.

When we do collagen induction therapy another name for microneedling, we make injuries by creating microscopic holes into the epidermis layer. Collagen fibers are laying parallel to the skin service. By creating injuries cells start communication between each other by producing more collagen into the skin.

Microneedling breaching these 3 layers ( acid mantle, corneocyte and lipid bilayers) and allowing nutritional products to penetrate deeper and trigger an immune response.

The skin consists of 5 different layers. The outer layer of the skin composed of entirely dead cells. 

There are 3 different sets of layers of the skin.

• Epidermis – first 5 layers
• Dermis- next 2 layers
• Subcutaneous tissue which is also known as hypodermis.

We need to keep the 3 layers healthy. When we neglect these 3 important layers, it causes inflammation and premature aging.

Microneedling breaching these 3 layers and allowing nutritional products to penetrate deeper and trigger an immune response.

Ok, now let’s move to the next lesson
