The science behind your Microdermabrasion Facial!


Our skin can easily restore itself and here is how it does post microdermabrasion treatment!


Recently through my studies I have been able to encapsulate so much knowledge but I thought I must share in a way for you all to learn the greatness of this treatment and our skin! For Dermal specialists do the treatment but it is really your skin that does the hard work!



Firstly, What is microdermabrasion?


In clinic, there are two kinds of microdermabrasion treatments. Both mechanically exfoliate your outermost layer of skin but in different ways. The purpose of Microdermabrasion is to

disrupt and partially exfoliate your Stratum Corneum (outermost layer). The Diamond Microdermabrasion machine exfoliates with the use of a diamond tip that removes built up debris (dead skin) on the surface. This is through a vacuum suction that glides in back and forth motions on the skin to lift the debris off. This is done successfully with a educated and trained dermal specialist who completes numerous passes to remove debris, dirt, pollutants and more into the hand piece.


How does the skin recover from this treatment?

Your skin goes through 3 healing stages after treatment is performed. The purpose to the controlled trauma performed, is for your skin to naturally rebuild its own barrier function.


1) Inflammation stage

Your skin has just gone through some intended injury and instantly within minutes inflammation begins to arise. This is where your neutrophil and cytokine cells are sent for immediate response to start the repairing process. The point to understanding this stage is the normal reaction and response our skin has instantly after a microdermabrasion.


2) The rejuvenation stage

This occurs within hours of post treatment where the migration of 'stem cells' that are being produced are sent to your basal layer (within the top layer of skin). These cells are sent to repair the area and allow the tissue growth of new altered collagen to strengthen the skin's structure again.


3) Tissue repair

This is the last stage that can occur with 24 hours post microdermabrasion treatment where your TEWL (trans - epidermal water loss) increases. This however within 1 week resumes to normality and through studies have even shown a decrease in TEWL. This indicates how our skins barrier can strengthen post treatment and enhance your lipid bilayer (also in top layer of skin) (Rajan & Grimes, 2002).


What is your outermost layer of skin?


The Stratum Corneum (SC) is a vital part to protection, as without all of its components it cannot prevent threats in our environment such as pathogens (bacteria) from entering. It also is vital to sustain hydration. These elements provide its strength, resilience and ability for your skin to repair. Microdermabrasion is able to provide evidence that when non - invasive controlled injury is made, the skin will quickly repair itself and rebuild the SC strength and function in order to maintain its overall integrity.


Simplifying the Facts!

The SC is essential for the human skin as it can easily restore itself and can regenerate itself quickly after having physical or chemical injury to it such as a microdermabrasion treatment.


The benefits to having this treatment is how it improves your skin's overall integrity (health), this is through resurfacing the SC. It has been able to provide assistance to clients experiencing congested pores, uneven texture, pigmented acne scarring and more!



Here are the resources used from Victorian university database. These resources were used to create my assessment report upon the stratum corneum and the microdermabrasion treatment that disrupts the barrier. This assessment and the resources found inspired me to create my first blog article to teach you all!
