Exfoliation is a method that is used to remove the dead skin cells and leave behind the fresh new skin cells. This gives the skin improved quality and appearance. Skin cells can become old and harden and lose moisture, and the appearance of the skin then becomes dull and dry, and the pores can become clogged. Exfoliation removes these old, dry, dull skin cells, and stimulates the renewal of new, healthy skin cells, leaving the skin looking young and smooth.

Physical exfoliants use a brush or a gentle abrasive to cause friction to remove the dead skin cells from the skin's surface. There are different exfoliant products designed to suit different skin types.

Chemical exfoliants use Alpha Beta Hydroxy acids, glycolic acid, enzymes, and retinal to remove dead skin cells. These substances dissolve the intercellular that attaches the skin cells to the skin surface. For the best and safest results with chemical exfoliants, an Esthetician will perform professional facial treatments over a period of six weeks. Enzymatic and hydroxyl acids are safe for home use and are available for personal use in the home. Glycolic acid is widely used in many skincare products.

In youth, the skin cell renewal process takes 25 to 30 days, but as we get older, this process slows down and can take up to 90 days. The slower, natural removal of skin cells causes dull, thick, saggy, and dehydrated skin. When you use an exfoliant, you help to remove the dead, dry cells that would typically take longer, and so you assist in helping the skin become hydrated, firmer, and much smoother. Exfoliation is very effective on mature and pre-maturing skin as it stimulates the cell renewal much faster than the body will do on its own.

When the skin is dehydrated, it doesn't contain enough moisture and will feel tight and stretched. When people have dehydrated skin, they tend to use lots of moisturizer in an attempt to moisten the skin, but moisturizer leaves the old skin cells stuck on the surface, and the skin appears dull and uneven. Exfoliation will remove those dead, dehydrated cells and will moisturize and hydrate the skin. These specific skincare products will reach much deeper into the layers of skin, helping to moisturize deeply and keep the skin hydrated, and there is then no need to use heavy moisturizing creams.

If you have oily and acne-prone skin, then you are likely to have five times more dead skill cells than healthy or dry skin. The fatty dead skin cells will clog the pores contributing to acne. Exfoliation will remove the dead skin cells, which help to remove the clogged pores and leave you with a fresher, brighter complexion.

Other skin problems are sun-damaged skin, hyperpigmented skin (which is caused by sun damage), or hormonal changes. These problems can increase the melanin of the skin, which can cause dark patches. Exfoliation can help to remove those dark patches by renewing the skin cells faster and preparing the surface for the use of products that help to reduce the melanin production and leave lighter skin.
