Exfoliation isn’t a must for everyone. Learn how to spot when your skin needs it, which formulas are a match, and how to avoid damaging your skin barrier.
From scrubs to serums, exfoliation is everywhere but too much of a good thing can quickly backfire and leave skin red, irritated and generally upset. Here’s how to make smarter choices for smoother, healthier-looking skin.
Exfoliation has become one of the most talked-about steps in skincare. It promises to reveal a glow, increase smoothness, and enhance skin’s clarity. It can deliver but only if it’s properly understood. The hard truth? It’s not a universal must-have. “I’m not really a fan,” says Dr. Marylise Plasqui, an aesthetic and anti-aging physician. The most important thing to understand about exfoliation is that it should be thought of as a targeted step that depends entirely on what your skin is going through, rather than a viral video.
Let’s start with what exfoliation really is.
What’s happening on your skin
Exfoliation isn’t just about smoothing a dry or bumpy complexion; it’s about removing what your skin would eventually shed on its own.
“From a dermatological perspective, exfoliation means removing the cells from the stratum corneum that accumulate on the surface of the skin,” says Dr. Plasqui. However, the natural cycle of your skin doesn’t necessarily need extra help with this.
“The epidermis renews itself from what we call the basal layer,” she explains, “Cells are produced there, then gradually move up, eventually dying and becoming keratinized, forming the stratum corneum.” That’s what is removed when we exfoliate, she says.
In other words, exfoliation speeds up a process your skin is already designed to handle.
Scrub, serum, lotion: what’s the difference?
The options for exfoliating products can feel overwhelming, but most formulas fall into two categories.
“We often talk about mechanical exfoliation and chemical exfoliation,” says Dr. Plasqui. The former includes scrubs, masks or cleansers that have a grainy texture. Using ingredients which can be derived from pumice stone, sugar, or kernels of seeds or nuts, mechanical exfoliation relies on granules massaged in gentle circular motions to buff off dead skin on the surface.
Chemical exfoliants, often found in serums, lotions, toners and peels, work slightly differently. They contain ingredients, such as enzymes, alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs), that break down the sticky bonds between dead skin cells. That process makes the old cells fall away from the barrier and leaves skin refined. Effective AHAs and BHAs include glycolic, lactic and salicylic acid, which also reduce excess sebum that can contribute to blemishes.
But here’s the key: you don’t need all of them. “Exfoliation should not be an automatic step for everyone,” says Dr. Plasqui, “It should only be done when the skin actually needs it.”

Who actually benefits from exfoliation?
Exfoliation is not a skin type decision. It’s a skin state decision. Carefully considering the state of your skin will help you identify whether it’s a suitable candidate for this targeted skincare step. “Exfoliation is more appropriate for thicker skin types or for skin showing signs of significant keratinization,” says Dr. Plasqui. That means your skin has accumulated a layer of excess dead cells. Having a dull complexion, being a smoker or vape user, or frequent exposure to the sun are additional factors that can make exfoliation right for you.
Still unsure if exfoliation is right for you? Let Noli help. The diagnostic tool takes out any guesswork, and assesses your skin using personalised data to find an unbiased match as needed.
There are also certain skin types that do not respond well to exfoliation. “If you have sensitive skin, you should absolutely avoid it,” she says, “Skin that is already struggling to renew itself or showing signs of stress should not be exfoliated, as it can make things much worse.”
When exfoliation becomes too much
Take note because this is big: for any skin type excessive exfoliation can do more harm than good. “Routines that recommend exfoliating every day, for example with an exfoliating lotion, are a clear no,” says Dr. Plasqui. This is a case where doing less will help you achieve better results. “The more you exfoliate, the more your skin will try to compensate, making you feel like you need to exfoliate even more,” she says. Being too aggressive can create a cycle that can lead to what the expert calls ‘over-polished’ skin, which has a distinct look and feel. “When the skin can no longer renew itself properly, its hydrolipidic film becomes unbalanced,” says Dr. Plasqui, “It becomes too shiny, thinner, and much more sensitive.” In a word: ouch.
The smarter way to exfoliate
Successful exfoliation requires moderation, which comes down to only doing it when needed. That could be once or twice a week, or bi-monthly, depending on your skin. If used thoughtfully as a gentle treatment, it can refine texture and boost radiance. When overdone, it disrupts everything your skin is trying to protect.
The takeaway? Listen to your skin, not the trend cycle.
Exfoliation isn’t a routine step. It’s a decision.The goal isn’t smoother skin at all costs. It’s skin that functions properly—and that starts with understanding what it actually needs.
If your skin actually needs exfoliation, here are a few formats that can work—depending on your profile.
