Whether you’re a seasoned skin-care enthusiast or just dipping your toes into the world of acids and scrubs, exfoliation can be confusing. How often? Which products? Mechanical or chemical? Here’s a complete guide to demystifying the process, so you can glow confidently—without going too far.
Why exfoliation matters more than you think
Exfoliation is often hailed as the secret to soft, glowing skin—but for many of us, it’s also one of the most misunderstood steps in a skincare routine. Should you exfoliate daily? What kind of exfoliant is best for your skin type? And how do you know when you’ve gone too far?
At its core, exfoliation is the process of removing dead skin cells from the surface of your skin. This not only reveals a brighter complexion underneath, but also helps improve texture, unclog pores, and allows your other skincare products to penetrate more effectively. “Exfoliation can have significant benefits for your skin when done safely and correctly,” explains board-certified dermatologist Dr. Tiffany Jow Libby. Esthetician Shani Darden agrees, noting that nearly every skin type can benefit from regular exfoliation—if done right.
How often should you exfoliate?
The ideal exfoliation frequency isn’t one-size-fits-all. It depends on your skin type, the kind of exfoliation you’re doing, and the rest of your skincare routine. If you’re just starting out, Dr. Libby suggests exfoliating once or twice a week and slowly building up to three times a week—if your skin can handle it.
The key is listening to your skin and not overdoing it. Redness, irritation, tightness, or flaking are all signs you might be pushing too hard. Darden recommends avoiding multiple active ingredients on the same day (like exfoliants and retinoids), and spacing them out to avoid stressing your skin. It’s also wise to read product labels carefully to ensure you’re not unknowingly doubling up on exfoliating ingredients across your routine.
Choosing your method: mechanical vs. chemical
There are two main types of exfoliation: mechanical (also known as physical) and chemical. Mechanical exfoliation involves physically sloughing off dead skin using scrubs, brushes, or dermaplaning tools. This is often what people first think of when they hear the word “exfoliate.”
Chemical exfoliation, by contrast, relies on acids—like AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids)—to dissolve the glue that holds dead skin cells together. Chemical exfoliants have become increasingly popular for good reason: they tend to be gentler on the skin and often deliver more consistent results. “Start by using a cleanser once a week that contains salicylic acid, glycolic acid, or lactic acid,” advises Dr. Libby. From there, you can increase the frequency depending on your skin’s tolerance.
For sensitive or rosacea-prone skin, she recommends lactic acid for its hydrating and gentle properties. For oily or acne-prone skin, salicylic acid is a go-to because it’s oil-soluble and can penetrate deep into clogged pores.
Still too harsh? Darden suggests using cotton gauze to gently remove your cleanser. “The gauze will provide a light exfoliating effect,” she says. “It’s a great alternative for anyone with very sensitive skin.”
Signs of over-exfoliation—and how to fix it
It’s easier than you think to over-exfoliate, especially when you’re eager to chase that elusive glow. One red flag? Your skin feels squeaky clean. While it might sound like a good thing, that sensation often signals that you’ve stripped your skin’s natural barrier.
“Over-exfoliated skin is usually dry, itchy, red, and uncomfortable,” says Dr. Libby. If you’ve gone too far, the best thing to do is hit pause. Stop all actives—including exfoliants and retinoids—and focus on healing and hydration. Switch to a gentle cleanser, avoid exfoliating ingredients, and layer in a hydrating serum with hyaluronic acid both morning and night. Above all, give your skin time to recover. Once the barrier is repaired, you can begin reintroducing actives slowly, ideally one at a time.
Don’t forget your body—but know where to draw the line
While facial exfoliation gets most of the attention, your body can benefit too. The skin on your body is generally thicker and can often tolerate more vigorous exfoliation. Darden recommends using a gentle physical scrub like the Nyakio Kenyan Coffee Body Scrub once a week. “It’s effective and leaves the skin feeling luxurious,” she notes.
Dr. Libby, however, leans toward chemical exfoliants for the body as well. She suggests opting for a body wash that contains ingredients like glycolic or salicylic acid to help with texture, keratosis pilaris, or body breakouts.
That said, not every body part needs—or can tolerate—exfoliation. “Avoid exfoliating the lips,” warns Dr. Libby. “The skin there is thinner and has no oil glands, making it more prone to damage.” Instead, opt for a hydrating lip balm. Similarly, proceed with caution when exfoliating your neck and chest. These areas are often more sensitive than the rest of your body and may not tolerate exfoliants as frequently as your face.
Final thoughts: gentle consistency wins the glow
The journey to radiant skin doesn’t require scrubbing daily or layering acids aggressively. In fact, the opposite is often true. The best exfoliation strategy is one that’s consistent, balanced, and tailored to your unique skin type and concerns.
By choosing the right method, paying attention to your skin’s responses, and giving it time to adjust, exfoliation can be one of the most rewarding steps in your skincare routine. And remember—sometimes the best glow comes not from doing more, but from doing just enough.
