The Beauty Blogger's Guide to Exfoliation

Thursday, February 25, 2016

Exfoliation is one of the most overlooked steps on people’s skincare regimens. It is also one of the most important. People seem to be aware of the fact that using an exfoliant is crucial, but they are often unsure of why it’s necessary.

An Intro to an Essential Skin Care Step

The skin that you are seeing right now is actually dead skin cells. It sounds far-fetched, but your skin sheds approximately 35,000 skin cells per minute. It is part of a 28-cycle where our skin is constantly exfoliating itself. This process slows down around the age of 35 and skin may appear bumpy or uneven and dull as if it has lost its glow.

These skin symptoms are caused by an accumulation of dead skin cells on the sratum corneum, or the top most layer of the skin. When we exfoliate the skin, we are speeding up cell turnover by sloughing off the accumulated dead skin cells. The result? A fresher, more radiant complexion with a smoother texture.

Exfoliation also helps your other skin care products work better. Picture an old door that you would like to repaint. The door is peeling, with layers of paint and environmental debris. If you attempted to paint over the door, the door would still be peeling and worn. It would be uneven and the painted would not be smooth and flat. Instead, what would you do first? To get a smooth paint finish, chances are you would scrape off the old paint, sand it down, and prep it for the rest of your painting.

This concept can be applied to your skin. If your skin is dull and uneven with an accumulation of dead skin cells, your other skin care products will not work as efficiently. Once you have exfoliated, however, the active ingredients in your skin care treatments will penetrate more deeply and reach the pores. Another perk? Your skin will look younger with regular exfoliation.

Mechanical vs. Chemical: Which is better?

There are two main varieties of exfoliation, each with its own advantages. It’s a matter of finding the best treatment for your skin’s needs.

What does the Derm say?

I recently talked to board-certified dermatologist Dr. R. Sonia Batra of Batra Dermatology in Santa Monica, CA to get the scoop on skin sloughing. She broke down the two key types of exfoliation -- mechanical and chemical -- and explained the benefits of each.

Mechanical Exfoliation

Mechanical exfoliation, or physical exfoliation, uses scrubs, sponges, microdermabrasion and brushes to buff off dead skin cells. Dr. Batra recommends this form of exfoliation to older people whose skin is becoming dry or showing signs of dullness, as opposed to those with oily and acne prone skin.

Just say NO to nutshells: What to look for in a manual exfoliant

  • When choosing a facial scrub, be sure it is free of nut shells, as they can scratch the skin and do more harm.
  • Avoid scrubs with polyethelene beads, as these are bits of plastic that harm the earth. 
  • Look for natural fibers in sponges and brushes as opposed to synthetic. 
  • Mechanical exfoliation should be done no more than twice a week. 

Products to try:

Bliss Micromagic Microdermabrasion Treatment contains volcanic pumice and aloe vera to remove surface impurities.

One Love Organics Cleansing Sponge is made of 100% pure plant fibers and bamboo charcoal to gently exfoliate and clean the pores. Simply apply your gentle cleanser to the sponge and use instead of a traditional washcloth. ($10)


Chemical Exfoliation


Chemical exfoliation is different. You may hear it referred to as chemical peeling, even though a true chemical peel is not a procedure one would do at home. A chemical exfoliant involves the use of skin care products formulated with hydroxy acids (alpha, beta, etc.), retinoids, or enzymes to loosen the connection between skin cells and stimulate cell turnover. Chemical exfoliation can remove several layers of skin, help correct sun damage, and treat wrinkles. Dr. Batra recommends this type of exfoliation is for acne prone skin. NEVER use a manual (scrubby) exfoliant on acne. It is one of the worst things you can do!

Choosing the right chemical exfoliant


  • Beta hydroxy acid (look for salicylic acid) is best for acne, blackhead, whiteheads and rosacea. BHAs, unlike other hydroxy acids, can penetrate and unclog the pores. Another benefit of BHAs is that they are anti-bacterial. 
  • Alpha hydroxy acids are best for sun-damaged or dry skin. These acids cannot unclog pores. Of the different AHAs, glycolic has the smallest molecular size and is best able to penetrate the skin. 
  • Retinol (topical Vitamin A) works to encourage cell turnover from the deepest layers up, as opposed to working primarily on the outer layers. It is effective for deeper wrinkles. 
  • Fruit enzymes are ideal for congested skin. Looks for products containing pineapple or papaya, because they contain bromelain and papain to lift off dead skin cells. 

Chemical exfoliants to try at home:

ZENMED AHA/BHA Complex is used like a toner and exfoliant in one. AHA helps to improve the look of patchy, flaky skin while the BHA works to unclog bacteria from the pores. ($20)

RoC Retinol Correxion MAX Wrinkle Resurfacing System targets deep lines and wrinkles over time using a stable form of retinol. ($30)

Caudalie Glycolic Peel features papaya enzymes and glycolic acid to stimulate cell renewal. It works well on sun damaged skin. ($39)


You can get too much of a good thing.

A word of caution when it comes to skin exfoliation. Many people are so happy with the results they see from their exfoliation that they decide to do it daily instead of as recommended. Excessive exfoliation can damage the skin and even make you look older. Use your products only as recommended and you’ll see your long-lost glow beginning to return.
