Exfoliation is a crucial step in any skincare routine, helping to remove dead skin cells, unclog pores, and reveal a brighter, smoother complexion. Both chemical exfoliants like AHAs/BHAs and physical exfoliants offer unique benefits. However, using them together can lead to over-exfoliation, causing irritation and damage to your skin. Understanding how to balance these powerful exfoliants is key to maintaining healthy, radiant skin.
Here’s everything you need to know about AHAs, BHAs, physical exfoliants, and how to use them safely without over-exfoliating your skin.
What Are AHAs/BHAs?
AHAs (Alpha Hydroxy Acids)
AHAs are water-soluble acids derived from fruits and milk. Common AHAs include glycolic acid, lactic acid, and mandelic acid. They work by breaking down the bonds between dead skin cells, allowing them to be sloughed off more easily. AHAs are effective in treating surface-level skin concerns such as dullness, fine lines, and uneven skin tone.
Benefits of AHAs
- Exfoliation: Removes dead skin cells and promotes cell turnover.
- Brightening: Improves skin tone and reduces hyperpigmentation.
- Anti-Aging: Reduces the appearance of fine lines and wrinkles.
- Hydration: Some AHAs, like lactic acid, have moisturizing properties.
BHAs (Beta Hydroxy Acids)
BHAs are oil-soluble acids, with salicylic acid being the most well-known. They penetrate deeper into the pores to remove excess oil and debris, making them ideal for acne-prone and oily skin.
Benefits of BHAs
- Exfoliation: Removes dead skin cells and unclogs pores.
- Anti-Acne: Reduces the occurrence of breakouts by penetrating and clearing pores.
- Anti-Inflammatory: Soothes and calms irritated skin.
- Oil Control: Helps to regulate sebum production.
What Are Physical Exfoliants?
Physical exfoliants use small, abrasive particles or tools to manually slough off dead skin cells from the surface of the skin. Common physical exfoliants include scrubs with ingredients like sugar, salt, or crushed nuts, and tools like cleansing brushes or exfoliating gloves.
Benefits of Physical Exfoliants
- Immediate Results: Provides instant smoothness and a polished appearance.
- Stimulates Circulation: Enhances blood flow, promoting a healthy glow.
- Versatile: Can be used on various parts of the body for effective exfoliation.
The Risks of Over-Exfoliation
Signs of Over-Exfoliation
- Redness and Irritation: The skin may become red, inflamed, and sensitive to touch.
- Dryness and Flaking: Excessive exfoliation can strip the skin of its natural oils, leading to dryness and peeling.
- Breakouts: Over-exfoliation can disrupt the skin barrier, leading to increased breakouts and acne.
- Increased Sensitivity: The skin may become more sensitive to other skincare products and environmental factors.
Why Over-Exfoliation Happens
Over-exfoliation occurs when the skin’s natural barrier is compromised due to excessive removal of dead skin cells. This can happen when combining multiple exfoliants (like AHAs, BHAs, and physical exfoliants) too frequently or using them in high concentrations without allowing the skin to recover.
How to Safely Incorporate AHAs/BHAs and Physical Exfoliants
Alternate Between Chemical and Physical Exfoliants
One of the best ways to avoid over-exfoliation is to alternate between chemical exfoliants (AHAs/BHAs) and physical exfoliants. For example, you can use a chemical exfoliant a few times a week and a physical exfoliant once a week. This approach allows your skin to benefit from both types of exfoliation without overburdening it.
Start Slow and Build Tolerance
If you’re new to exfoliation, start slow and gradually build up your skin’s tolerance. Begin with a lower concentration of AHAs or BHAs and use them less frequently. As your skin adjusts, you can increase the frequency and concentration. For physical exfoliants, start with gentle products and avoid harsh scrubs that can cause microtears in the skin.
Pay Attention to Your Skin’s Response
Always listen to your skin. If you notice signs of irritation, redness, or increased sensitivity, reduce the frequency of exfoliation. Your skin’s needs can change due to various factors such as weather, stress, and hormonal fluctuations, so adjust your exfoliation routine accordingly.
Hydrate and Soothe
After exfoliating, it’s essential to hydrate and soothe your skin to support its barrier function. Look for products containing hydrating ingredients like hyaluronic acid, glycerin, and soothing agents like aloe vera, chamomile, and ceramides. These will help to restore moisture and calm any irritation.
Use Sunscreen
Exfoliation can make your skin more sensitive to the sun. Always apply a broad-spectrum sunscreen with an SPF of 30 or higher during the day to protect your skin from UV damage. Reapply as needed, especially if you’re spending extended periods outdoors.
Consider Your Skin Type
Your skin type can influence how often you should exfoliate and which types of exfoliants to use. For example:
- Sensitive Skin: Use gentle exfoliants and limit exfoliation to once or twice a week.
- Oily/Acne-Prone Skin: BHAs can be particularly effective, but avoid overuse and harsh physical scrubs.
- Dry Skin: AHAs with moisturizing properties, like lactic acid, can be beneficial. Exfoliate less frequently to avoid dryness.
- Combination Skin: Alternate between different types of exfoliants and adjust the frequency based on how your skin responds.

Conclusion
Exfoliation is a key component of a healthy skincare routine, but it’s essential to use both chemical and physical exfoliants wisely to avoid over-exfoliation.

Remember to hydrate, soothe, and protect your skin from the sun to maintain its health and vitality.
