Social media can make the ordinary seem extraordinary. Take exfoliation, for instance, the process of removing dead cells from the skin’s surface. If you’ve been scrolling through TikTok recently, you might think this time-honored skincare practice can rejuvenate your aging epidermis.
However, that might be setting the bar a bit too high.
Exfoliation isn’t going to fix anyone’s wrinkles. While exfoliation does have its benefits, it can also irritate and inflame the skin if done improperly or with unsuitable tools or chemicals.
How is exfoliation done?
Exfoliation can be achieved through two main methods: mechanical and chemical. Each method has its own advantages.
Mechanical (or physical) exfoliation uses tools like brushes, sponges, or scrubs containing abrasive particles to physically remove dead skin cells. Physical exfoliation can improve skin luster by shedding a dead layer of skin that can make it look dull. It can also help unclog pores, reducing some types of acne.
Chemical exfoliation, on the other hand, uses chemicals like alpha and beta hydroxy acids or salicylic acid to dissolve dead skin cells. Chemical exfoliants work on a micro-level to help dissolve excess skin cells and reduce uneven pigmentation on the skin’s surface. They also restore skin glow, improve acne, and give the skin a little more shine.
Why do skin care products often promote exfoliation?
Perhaps hundreds of skin care products, from body washes to cleansers to face masks, are labeled as exfoliating. However, I’m skeptical about why such a wide array of products emphasize this feature.
It’s advantageous for a cosmetics company to sell consumers more products in a skincare line. But it’s buyer beware, because this is a completely unregulated market, and cosmetic companies can make claims that don’t have to be substantiated in actual clinical trials.
Do we need to exfoliate our skin?
Nothing happens if you don’t exfoliate — you just walk around with bumpy or slightly dry skin, which is inconsequential except for cosmetic reasons.
No one has to exfoliate, but it can be helpful to exfoliate the arms and legs. As we age, these areas get more dry than other parts of the body, and people notice they build up a lot more flaking skin and an almost fish-scale appearance.”
This phenomenon may or may not be a sign of keratosis pilaris, a common but harmless skin condition characterized by rough, bumpy “chicken skin” on the upper arms and thighs. Physical exfoliators are a good first choice because keratosis pilaris covers areas that have tougher skin than the face.. But it’s fine to use a cleanser or lotion containing a chemical exfoliant instead. Either type can improve skin texture and the skin’s appearance.
Can exfoliation harm our skin?
Yes, both physical and chemical exfoliation techniques can do more harm than good, depending on several factors. Sensitive skin is more likely to become irritated or inflamed by any exfoliant. And overdoing it — whether by rubbing too hard or using a a product with higher concentrations of acid — can trigger irritant contact dermatitis, which can look red, angry, and chapped.
Natural Exfoliants
Exfoliation is a crucial step in any skincare routine, but not all methods are created equal. While highly acidic chemicals and harsh mechanical exfoliants can effectively remove dead skin cells, they can also cause irritation, inflammation, and even damage the skin’s protective barrier. On the other hand, home exfoliation using natural products is a gentler, safer alternative.
Natural exfoliants like oats, sugar, and coffee grounds offer a physical exfoliation that’s less abrasive than harsh scrubs or chemical peels. These substances have a softer texture, which means they can effectively remove dead skin cells without causing irritation or micro-tears in the skin. They’re also less likely to disrupt the skin’s natural pH balance, which can lead to dryness, redness, and sensitivity.
Moreover, natural exfoliants often contain additional beneficial properties. For instance, honey is a natural humectant that helps retain moisture within the skin, while yogurt contains lactic acid, a type of alpha hydroxy acid that helps dissolve dead skin cells. These natural ingredients can provide additional benefits like hydration and brightening, making them a safer and more holistic approach to exfoliation.
- Oats: Ground oats make a gentle exfoliant that’s great for sensitive skin. They contain saponins that help remove dirt and oil, and their texture provides a light physical exfoliation.
- Coffee Grounds: The caffeine in coffee grounds can stimulate blood flow, which can help reduce the appearance of cellulite and give your skin a more even tone.
- Sugar: Sugar is a natural humectant that helps keep moisture within the skin. It’s a versatile exfoliant that can be used on both the face and body.
- Salt: Salt is a natural antiseptic and it may help kill bacteria even beneath the surface of the skin. It’s a coarser exfoliant that’s better suited for the body.
- Baking Soda: This versatile ingredient is great for exfoliating the skin. It’s fine enough to use on the face, but it’s also effective for a full-body scrub.
- Honey: Honey is a natural humectant that helps retain moisture in the skin. It also has antibacterial properties that can help soothe and heal skin.
- Yogurt: Yogurt contains lactic acid, a type of alpha hydroxy acid that helps dissolve dead skin cells. It’s a gentle exfoliant that’s great for sensitive skin.
- Papaya: Papaya contains the enzyme papain, which is excellent for breaking down keratin, a protein that acts as a glue to keep dead skin cells together. Applying mashed papaya or a papaya mask
