Removing dry skin comes down to two steps: gently clearing away the dead, flaky cells on the surface, then restoring moisture so new skin stays soft. The approach differs depending on whether you’re treating your face or body, and the products you layer on afterward matter just as much as the exfoliation itself. Here’s how to do it effectively without damaging the healthy skin underneath.
Why Dry Skin Builds Up
Your skin’s outermost layer, the stratum corneum, acts as a barrier that holds moisture in and keeps irritants out. When that barrier is compromised, water escapes through the skin faster than it should. This process, called transepidermal water loss, leaves skin dehydrated, tight, and flaky. The dead cells that would normally shed on their own start clumping together instead, creating that rough, patchy texture.
Common triggers include low humidity, hot showers, harsh soaps, aging, and certain skin conditions like eczema. In people with eczema, research from Acta Dermato-Venereologica found that water loss is elevated even in skin that looks clinically normal, suggesting the barrier defect runs deeper than the visible dryness. Whatever the cause, the fix involves removing the buildup and then reinforcing the barrier so it doesn’t happen again as quickly.
Chemical vs. Physical Exfoliation
There are two main ways to clear dead skin: chemical exfoliants that dissolve the bonds holding dead cells together, and physical exfoliants that manually scrub them off. Both work, but they suit different skin types and body areas.
Chemical Exfoliants
Alpha-hydroxy acids (AHAs) like glycolic acid and lactic acid weaken the “glue” between dead skin cells so they slough away on their own. They’re generally milder than scrubs, which makes them a better fit for sensitive or dry skin that’s already irritated. Because they don’t involve any rubbing, there’s less risk of overdoing it. The tradeoff: AHAs increase sun sensitivity, so you’ll need sunscreen the following day.
Urea is another chemical option worth knowing about, especially for stubborn dry patches on the body. Products with less than 10 percent urea hydrate dry skin. Between 10 and 20 percent, urea becomes actively exfoliating, breaking down and loosening flaky buildup. Concentrations above 20 percent are reserved for very thick, calloused skin or nail issues.
Physical Exfoliants
Scrubs, washcloths, brushes, and exfoliating mitts physically buff away dead cells. They can improve rough texture and even fine lines over time, and some research suggests regular physical exfoliation may stimulate collagen production. The downside is that they can create micro-tears in the skin, leading to redness, irritation, or infection. If your skin is already dry and sensitive, a gentle washcloth is safer than a coarse sugar or walnut shell scrub.
Face and Body Need Different Approaches
Facial skin has a thinner outer barrier than body skin, which makes it more permeable to products but also more vulnerable to irritation. It loses moisture faster and turns over cells more quickly. Body skin, particularly on the back and thighs, has a thicker dermis that can handle more aggressive treatment.
This matters for product selection. Exfoliating body scrubs and lotions often contain higher concentrations of active ingredients that would irritate your face. A body lotion with 15 percent urea might work perfectly on rough elbows but sting or redden your cheeks. Always use products specifically formulated for the area you’re treating. For the face, stick to gentle AHAs or a soft washcloth. For the body, you can use stronger acids, urea-based creams, or textured scrubs.
How Often to Exfoliate
If you have dry or sensitive skin, twice a week is the maximum frequency dermatologists typically recommend. If you’re also using retinoids or other products that cause dryness, scale back to once a week or even every other week. More frequent exfoliation strips away healthy cells before they’ve had a chance to mature, which worsens the dryness you’re trying to fix.
Pay attention to how your skin responds after each session. If it feels smooth and comfortable, your frequency is fine. If it feels tight, stings when you apply other products, or looks red and blotchy, you’re overdoing it.
The Right Way to Moisturize After
Exfoliation clears the path, but moisturizing is what actually resolves dry skin long term. Effective moisturizing involves two types of ingredients, applied in a specific order.
First, apply a humectant. Humectants like hyaluronic acid, glycerin, and aloe draw water from the air into your skin. They’re water-based and lightweight. Second, layer an emollient or occlusive on top. These are oil-based ingredients like petroleum jelly, shea butter, jojoba oil, or grapeseed oil. They create a physical seal over the skin that prevents moisture from escaping. If you reverse the order and apply the oil-based product first, it blocks the humectant from reaching your skin.
Timing matters too. Apply your moisturizer to damp skin, ideally within a few minutes of showering or washing your face. When skin is already wet, a moisturizer can seal that water in. If you wait until skin is completely dry, occlusive products may actually trap dryness rather than hydration. One exception: medicated creams and retinoids should go on dry skin, because damp skin increases absorption and can cause irritation.
Signs You’ve Gone Too Far
Over-exfoliation is surprisingly easy to mistake for progress. One telltale sign is a tight, waxy sheen that looks like a healthy glow but is actually raw, overexposed skin. Other classic signs include redness, burning, peeling, and small bumpy breakouts that weren’t there before. You might also notice that products you’ve used comfortably for months suddenly sting or cause redness.
If this happens, stop all exfoliation immediately. Switch to a simple routine of a gentle cleanser and a rich, fragrance-free moisturizer. It can take one to two weeks for the barrier to recover. Resist the urge to scrub away the flaking that occurs during healing, as that’s your skin repairing itself. When you eventually resume exfoliating, start at a lower frequency and with a milder product than whatever caused the damage.
Building a Simple Routine
For most people dealing with dry, flaky skin, an effective routine doesn’t require a dozen products. Here’s what it looks like in practice:
- Daily: Wash with a gentle, fragrance-free cleanser. While skin is still damp, apply a humectant (a serum or lotion with hyaluronic acid or glycerin), then seal with an emollient cream or petroleum jelly.
- One to two times per week: Exfoliate with a mild AHA product or a soft washcloth. On the body, you can use a urea-based lotion in the 10 to 20 percent range for both exfoliation and hydration in one step.
- As needed: Use a richer occlusive (like petroleum jelly or shea butter) on particularly dry spots such as elbows, knees, heels, and shins. These areas have fewer oil glands and lose moisture faster.
Hot water strips natural oils from the skin, so keep showers warm rather than hot, and limit them to 10 or 15 minutes. Pat skin dry with a towel rather than rubbing, and apply your moisturizer right away while that surface dampness is still present. These small adjustments, done consistently, often make a bigger difference than any single product.
