Exfoliation - what is it and why should I do it?

I get a lot of questions from my clients about exfoliation - what it is, how to do it properly, why it's important and so on.  I thought it was time to dispel the myths and get some good information out to you!

Exfoliation involves the removal of the oldest dead skin cells on the skin's outermost surface, and has been used for many years to help maintain skin. Exfoliation is involved in the process of all facials, during microdermabrasion or chemical peels at medical spas. Exfoliation can be achieved through mechanical or chemical means, and is important for skin health.

New skin cells are created in the skin's lower layer, the dermis. Over time, cells migrate to the surface of the skin and become more acidic. During their 30 day journey, they die and become saturated with keratin. Keratin is important because it protects the skin from outside elements. Through the aging process, and after menopause for women, the natural process of skin erosion becomes uneven, which gives skin a dry and rough character. Exfoliation removes the outer layer to reveal the newer skin beneath. This shedding of the outer layer unclogs pores, keeps skin clean, and helps reduce acne breakouts. Exfoliation should always be done after cleansing the skin. Exfoliation is important for men as it exposes the hair follicles, allowing a better shave. It is possible to over exfoliate, which dries and irritates the skin. The face is the part of the body most sensitive to exfoliation.Hence, provided that exfoliating causes the skin to dry out, it is very important to moisturize it, because dry skin can lead to wrinkle development.

Mechanical Exfoliation
This process involves physically scrubbing the skin with an abrasive. Mechanical exfoliants include microfiber cloths, adhesive exfoliation sheets, micro-bead facial scrubs, crepe paper, crushed apricot kernel or almond shells, sugar or salt crystals, pumice, and abrasive materials such as sponges,loofahs, brushes, and simply fingernails. Facial scrubs are available in over-the-counter products for application by the user. People with dry skin should avoid exfoliants which include a significant portion of pumice, or crushed volcanic rock. Pumice is considered a good material to exfoliate the skin of the feet. Microdermabrasion and Micro Diamondabrasion are also considered mechanical methods of exfoliation.

Chemical Exfoliation
Chemical exfoliants include scrubs containing salicylic acid, glycolic acid, fruit enzymes, citric acid, or malic acid which may be applied in high concentrations by a medical professional, or in lower concentrations in over-the-counter products. Chemical exfoliation may involve the use of products that contain alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs), or enzymes that act to loosen the glue-like substance that holds the cells together, allowing them to ease away. This type of exfoliation is recommended for people treating acne.  I have several great treatments available - just ask!

Exfoliation with Hair Removal

Some methods of hair removal also help exfoliate the skin.

• Waxing is a mechanical process which is done with the intention of plucking the hair, which also functions as a mechanical exfoliant. As this is done every two to eight weeks, it is not performed as frequently as many exfoliate, so it does not fully substitute for a regimen, but may substitute for a normal session in a regimen.
• Nair is an example of a chemical hair removal product which also functions as a chemical exfoliant. It is done more frequently than waxing (once a week rather than once a month) since it only destroys hair partially below the skin, rather than destroying the entire root as with waxing. Using it weekly can substitute for a weekly exfoliant regime. It is a very aggressive chemical and cannot be used on the face so other exfoliants would need to be used on the face.
• Wetshaving also has exfoliating properties; first, the action of moving a shaving brush vigorously across the skin washes the surface and removes dead skin at the same time. After applying the lather with a brush, the use of a double-edged safety razor or straight razor removes dead skin simply by the fact that the aforementioned razors are dragged much closer across the skin and remove dead skin more effectively than a cartridge or electric razor.
