Dry, Flaky Skin: What's Actually Causing It and How to Fix It

#TLDR

  • Dry, flaky skin (xerosis) results from moisture loss, a compromised skin barrier, or the wrong products.
  • Dry skin (a skin type) and dehydrated skin (a temporary condition) have different causes and different solutions.
  • A damaged skin barrier is often the root cause, and over-exfoliating or using harsh cleansers makes it significantly worse.
  • The right moisturizer contains ceramides, hyaluronic acid, and/or glycerin — not just water.
  • If flaking persists after adjusting your routine, a professional skin assessment can identify the exact cause and the right treatment plan.

What Is Dry, Flaky Skin?

Dry, flaky skin — medically called xerosis — is one of the most common skin concerns across all ages and skin types. Mayo Clinic describes it as skin that looks and feels rough, itchy, flaky, or scaly when the outer layer loses essential moisture and natural oils.

What surprises many people: you don't need cold weather to develop it. In Miami, where high outdoor humidity sits alongside constant indoor air conditioning, skin regularly loses moisture from the dry, cold air inside offices, cars, and homes — even in the middle of summer.

Flakiness happens when dead skin cells accumulate on the surface faster than the skin can shed them, or when the skin's protective barrier breaks down and can no longer hold onto moisture. Both mechanisms are fixable — but the fix depends on which one is at work.

What Causes Dry, Flaky Skin?

Mayo Clinic and UPMC HealthBeat identify the most common triggers:

Environmental factors

  • Cold or low-humidity air, including air-conditioned indoor spaces
  • Sun exposure and UV damage, which strip the skin's protective oils
  • Air pollution, which degrades the skin's outer protective layer

Lifestyle and habits

  • Hot showers or baths, which dissolve the skin's natural lipid film
  • Harsh, foaming cleansers that strip oil from the skin's surface
  • Overwashing the face

Age

  • Skin produces fewer natural oils as you get older, making xerosis more common after the mid-30s

Health and medications

  • Certain medications — diuretics, retinoids, antihistamines — reduce skin hydration
  • Conditions like diabetes and hypothyroidism can affect the skin's moisture balance

Your skincare products

  • Products with high alcohol content, fragrance, or strong actives (acids, retinol) can compromise the skin barrier and trigger flaking — more on this in the routine section below

CeraVe's guide to dry skin on the face notes that while dryness can affect all skin types at any age, people with chronically dry or sensitive skin are at greater risk — and may experience the condition year-round rather than just seasonally.

Dry Skin vs. Dehydrated Skin: What's the Difference?

These two conditions look similar but have different root causes, and treating the wrong one produces little improvement.

Dry skin is a skin type. According to CeraVe, it results from a lack of sebum (oil) production. People with dry skin naturally produce less of the oil that forms the skin's protective barrier. This is a chronic condition that requires ongoing management.

Dehydrated skin is a temporary condition. As Healthline explains, it occurs when the skin lacks sufficient water — and it can affect any skin type, including oily skin. Dehydrated skin typically appears dull, with more prominent fine lines, while dry skin feels tight, rough, and flaky.

The fix differs for each:

  • Dry skin needs moisturizers: products that add oil back into the skin, such as creams with ceramides or fatty acids
  • Dehydrated skin needs hydrators: ingredients that draw water into the skin, like hyaluronic acid or glycerin

Many people have both conditions simultaneously, especially after extended sun exposure or a summer of outdoor activity. When you're unsure which applies to you, a skin assessment from a licensed esthetician is the fastest way to get clarity and avoid guessing with the wrong products.

What Ingredients Actually Fix Dry, Flaky Skin?

Not all moisturizers address dry skin effectively. According to Jennifer Wong, DO, a dermatologist with Water's Edge Dermatology, "the best moisturizers for dry skin contain two or three key ingredients, no fragrance, and not too much water." She also cautions that popular gel or gel-cream moisturizers are often too light for people with true dryness.

The ingredients that genuinely work:

Ceramides

Ceramides are lipids (fats) that make up the structural "mortar" of your skin barrier. When ceramide levels drop, the barrier breaks down and moisture escapes. Replenishing ceramides topically helps seal the barrier. Mountain Dermatology Specialists identifies ceramides alongside cholesterol and fatty acids as the three critical components of a healthy skin barrier.

Hyaluronic Acid

A humectant that draws water from the environment and deeper skin layers into the surface. It works best when applied to slightly damp skin, then sealed with a cream or oil on top. Without that seal, it can actually draw water out of the skin in very dry conditions.

Glycerin

Another potent humectant — gentler and less discussed than hyaluronic acid, but equally effective at pulling water into the skin. CeraVe lists glycerin as a top ingredient for dry skin relief.

Shea Butter and Plant Oils

These are emollients and occlusives. They form a film on the skin that slows water evaporation, making them especially useful for very dry or persistently flaky skin.

A professional-grade option: GlyMed+ Elite Cell Protection Balm is a clinical occlusive balm formulated to lock in moisture and shield the skin's surface from environmental stressors — a strong choice for very dry or persistently flaky skin. It ships directly through the Skincare Concierge MIA store.

What to avoid: fragrances, high concentrations of alcohol, and overly watery formulas that feel refreshing but evaporate without delivering lasting hydration.

Is My Skin Barrier Damaged?

The skin barrier — technically called the stratum corneum — is the outermost layer of your skin. Mountain Dermatology Specialists describes it this way: skin cells act as the bricks, and lipids (ceramides, cholesterol, fatty acids) act as the mortar holding everything together. Together, they lock moisture in and keep bacteria, allergens, and pollutants out.

When the mortar breaks down, skin loses water faster, becomes more reactive, and starts to look rough and flaky.

Signs your barrier is compromised:

  • Products that never bothered you before now sting on contact
  • Persistent redness or patchy irritation with no obvious cause
  • Skin that feels tight within minutes of cleansing
  • Flaking that doesn't respond to regular moisturizer

Paula's Choice notes that a compromised barrier also reduces tolerance to active ingredients like retinol or acids — so if your skin has recently become reactive, the barrier is likely the culprit rather than any single product.

Repair takes consistent effort over several weeks. The protocol: simplify your routine, stop all actives temporarily, and use ceramide-rich, fragrance-free products twice daily until the skin stabilizes.

A professional-grade option: GlyMed+ Elite Barrier Repair Cream with Amino Acids is formulated specifically to rebuild a compromised barrier, delivering the lipids and amino acids the skin needs to restore its protective function. It ships directly through the Skincare Concierge MIA store.

Can My Skincare Routine Be Making It Worse?

Yes — and more often than people expect.

Westlake Dermatology identifies over-exfoliation as a leading cause of ongoing flakiness, noting that acid-based products or scrubs used too frequently strip the skin's natural oils and cause "irritation, inflammation, and long-lasting damage to the skin barrier." The rate of over-exfoliation has become a common skincare concern, especially with the growing popularity of at-home peels and acid-based serums.

Other routine-related culprits:

  • Foaming or sulfate-based cleansers that strip the skin's oil film
  • Alcohol-heavy toners that evaporate and leave skin drier than before
  • Retinol without adequate moisturizer as a buffer
  • Multiple actives (vitamin C, AHA, retinol) layered in the same routine without a skin adjustment period

A good rule: if dry skin appeared or worsened after you added a new product, that product is the likely cause. Strip the routine back to the basics — a gentle cleanser, a ceramide-rich moisturizer, SPF — then reintroduce actives one at a time after the skin recovers.

Should I Exfoliate Dry, Flaky Skin?

The instinct to scrub away flakes makes sense, but the approach and timing matter.

The Strategist consulted three estheticians on this question and found a clear consensus: "most exfoliators strip skin of moisture rather than deposit it, so you should address the dry skin first" before reaching for an exfoliant. Going straight to exfoliation on already-compromised skin tends to make flaking worse, not better.

The American Academy of Dermatology's guidance on safe exfoliation at home recommends factoring in your skin type before choosing a method and notes that dry skin can be fragile and prone to irritation from physical scrubs.

The balanced approach:

  • Exfoliate, but gently and infrequently. Once a week with a mild lactic acid product suits most dry skin types.
  • Skip harsh physical scrubs, which create micro-tears and worsen flaking on dry skin.
  • Hydrate first. If your skin is currently flaring, restore moisture for 1 to 2 weeks before reintroducing any exfoliant.
  • Stop immediately if exfoliation causes redness, stinging, or more dryness. These are signs the barrier is too compromised to tolerate it.

Lactic acid is particularly well-suited for dry, flaky skin: it removes dead cells gently and also functions as a humectant, drawing water into the skin as it works.

A professional-grade option: GlyMed+ Elite Peptide Micro Scrub is a gentle exfoliant formulated with peptides that removes dead skin cells without disrupting the skin barrier — well-suited for dry or sensitive skin that reacts to harsher scrubs. It ships directly through the Skincare Concierge MIA store.

When Should I See a Professional?

Some dry skin responds to a better routine and the right products. But there are situations where a professional assessment gives you answers that trial-and-error cannot.

Consider booking a skin consultation when:

  • Flaking persists despite consistently using the right products for 4 to 6 weeks
  • You're not sure whether your skin is dry, dehydrated, or both
  • Your skin has suddenly become reactive or sensitive after a product change
  • You want a personalized product recommendation instead of guessing at the drugstore
  • You've experienced seasonal or post-summer changes and want to reset your routine before fall

A licensed esthetician with clinical experience can assess your skin's actual moisture levels, barrier health, and oil production — then recommend a targeted treatment plan. This differs from a general beauty counter consultation, where recommendations are based on preferences rather than a skin analysis.

The Bottom Line

Dry, flaky skin is a symptom with several possible causes. Whether the issue is a dry skin type, temporary dehydration, a damaged skin barrier, or a product-related reaction shapes every decision from which moisturizer to buy to whether exfoliation will help or hurt.

The most consistent pattern in professional skincare: clients who simplify (fewer products, gentler formulas, consistent hydration) see better results faster than those who layer on more. Start simple, choose ingredients that repair rather than strip, and — if flaking persists — get a professional assessment rather than continuing to guess.

Your skin has the capacity to recover. It just needs the right support.
