Exfoliation involves eliminating dead skin cells and accumulated debris from the outermost layer of your skin, known as the epidermis.

You can employ either a chemical or physical exfoliation method to shed the old cells. This practice helps to prevent the blockage of pores/follicles and unveils the fresher, more vibrant skin beneath.

Exfoliation aids in the natural cellular turnover of your skin. This process begins in the deepest layer of the epidermis, where new cells begin. These young, fresh cells move upward through the various layers of the epidermis until they reach the surface of the skin. As these once-new cells make their way to the surface of the skin, they become lifeless, dry, and flaky.

Meanwhile, the process continues as a fresh set of new cells progresses from the base layer toward the surface to replace the dry, dead skin cells.  Although skin cell turnover is a natural progression, it slows down as one ages. Typically, in healthy, youthful skin, this cycle transpires every 28 days or so. However, as you grow older, it tends to slow down, ranging from 40 to 60 days, or potentially even longer.

Consequently, these dry, flaky dead skin cells aren’t replenished as swiftly, leading to a lackluster complexion, uneven skin tone, and breakouts resulting from obstructed pores.

It’s crucial to monitor how your skin responds to exfoliation. It’s easy to overdo it, which can lead to potential skin issues. If you notice redness, flakiness, dry patches, or a “waxy” appearance, it’s a sign that the exfoliation product you’re using may be too potent for your skin type or that you’re using it too frequently.

Over-exfoliation can compromise the skin’s natural barrier, stripping away essential oils. This can result in dehydration, the development of broken capillaries, and even new acne breakouts. Additionally, your skin may become more sensitive to other skincare products that were previously well-tolerated.

How does Exfoliation Benefit Your Skin?

Exfoliation offers multiple benefits for your skin’s appearance. It can lead to a brighter complexion and enhance the absorption of topical skincare products, maximizing their effectiveness. Additionally, consistent exfoliation aids in preventing clogged pores, reducing the occurrence of breakouts. Over time, it stimulates collagen production, a crucial element for achieving radiant and vibrant skin. Collagen not only supports skin elasticity but also helps diminish the visibility of fine lines and related sagging.


In the world of skincare, there are primarily two main approaches to exfoliation: physical and chemical. Within physical exfoliation, there are two distinct techniques: manual and machine-based.

There are several types of chemical exfoliation methods, each utilizing different types of acids or enzymes to promote cell turnover and reveal smoother, more radiant skin. Here are some of the main types:

Manual Exfoliation

This is the type of exfoliation most people know best and involves using your hands to manually slough off dead skin cells with textured products, such as scrubs, textured cloths, or sponges. Treatments including microdermabrasion and dermaplaning also fall under this category.

1. Scrubs: Manual exfoliation involves using products that contain small abrasive particles like corundum (microdermabrasion crystals), sodium bicarbonate (baking soda), sugar, or salt granules. To effectively remove dead skin cells, you gently massage these products onto your skin. The frequency of this method can vary depending on your skin type but is generally recommended 1–4 times per week. Regular exfoliation can help achieve a coveted radiant complexion by reducing dullness and improving skin tone, even addressing concerns like acne.

2. Machines, Devices & Other Tools:

Beyond manual techniques, there are various other tools and devices for physical exfoliation:

  • Facial Scrubbing Devices: These devices offer an advanced method for physical exfoliation. They can include facial scrubbers and microdermabrasion tools, designed to effectively remove dead skin cells and impurities. Cleansing devises are beneficial for clarifying and brightening dull or compromised skin, unclogging pores, and reducing excess oil without over-drying. Some facial cleansing brushes are made with gentle, anti-bacterial, clinical-grade silicone that provides a comfortable exfoliating experience while boosting blood circulation, leaving your skin with a radiant glow.
  • Face Mitts and Washcloths: Textured face mitts or washcloths are another handy option for manual exfoliation. They help slough off dead skin and impurities when used in your skincare routine.
  • Microdermabrasion: Microdermabrasion is a manual exfoliation method that involves using a specialized device to gently remove the outer layer of skin. This non-invasive procedure helps to unclog pores, stimulate collagen production, and reduce various skin concerns like fine lines, wrinkles, acne scars, hyperpigmentation, and sun damage. It enhances the absorption of skincare products and results in smoother, more even-toned skin with a healthy glow. While quick and generally painless, multiple sessions are often recommended for optimal results. Microdermabrasion is suitable for most skin types, but individuals with specific skin conditions may not be suitable candidates. Overall, it’s a popular choice for achieving a refreshed, rejuvenated complexion.

Whether you choose manual or machine-based methods, the key to successful exfoliation is to find the approach that suits your skin type and needs best. Remember, exfoliation should be a regular part of your skincare routine, but moderation is essential to avoid over exfoliation and irritation.

Chemical Exfoliation

Chemical exfoliation offers several advantages. It can be tailored to different skin types and concerns, and its effects are often more gradual and subtle compared to the immediate results of physical exfoliation. Regular use of chemical exfoliants can lead to improved skin texture, reduced fine lines, diminished hyperpigmentation, and a brighter complexion.

Alpha Hydroxy Acids (AHAs):

  • Examples: Glycolic acid (from sugar cane), Lactic acid (from milk), Citric acid (from citrus fruits), Malic acid (from apples), Tartaric acid (from grapes).
  • AHAs are water-soluble acids that work on the skin’s surface to loosen and remove dead skin cells. They are effective for addressing issues like fine lines, uneven skin tone, and sun damage.

Beta Hydroxy Acids (BHAs):

  • Examples: Salicylic acid (synthesized from salicin).
  • BHAs are oil-soluble acids that penetrate deeper into the pores. This makes them particularly effective for treating acne, blackheads, and congested skin. Salicylic acid is well-known for its ability to unclog pores and reduce inflammation.


  • Examples: Papain (from papaya), Bromelain (from pineapple), Pumpkin enzymes (from pumpkin).
  • Enzymes work by breaking down the proteins that hold dead skin cells together. This leads to a gentle and natural exfoliation. Enzymatic exfoliation is generally milder and suitable for sensitive skin types.
  • For best results, apply a thin layer of enzyme-based products to damp skin 1–4 times a week, allowing them to sit for 15 minutes before gently massaging and rinsing them off in circular motions. Enzymatic exfoliation is typically milder than acid-based exfoliation, making it suitable for sensitive skin types

Retinoids (Retinol, Retin-A):

  • Derived from Vitamin A, retinoids stimulate cell turnover and promote the production of collagen. They can be considered a form of chemical exfoliation due to their ability to shed dead skin cells and unclog pores.

Fruit Acids (Natural Acids):

  • Examples: Malic acid (from apples), Citric acid (from citrus fruits), Tartaric acid (from grapes).
  • These are naturally occurring acids found in various fruits. They provide a mild exfoliation and can be found in some skincare products.

Each type of chemical exfoliant offers unique benefits and suits different skin types and concerns. It’s important to choose the right type and concentration based on your individual skin needs, and to use them in accordance with recommended guidelines to avoid over-exfoliation and potential irritation.

However, it’s important to use chemical exfoliants with care. Starting with a lower concentration and gradually increasing frequency allows the skin to acclimate. Additionally, wearing sunscreen is crucial when using chemical exfoliants, as they can increase sun sensitivity.

Overall, chemical exfoliation is a versatile and effective method for achieving smoother, more youthful-looking skin. It’s a valuable addition to any skincare routine, helping to address a wide range of concerns and promote a healthy, radiant complexion.
