Winter skincare: how cold weather changes your skin and how to adapt your routine

Winter creates a specific skin environment that most people don't adapt their routines to — resulting in months of dryness, sensitivity, and barrier breakdown that reverses once they simply adjust what they're using. Here's the full picture.

What winter does to skin

Low absolute humidity

Cold air holds significantly less water vapor than warm air. Relative humidity describes water as a percentage of what the air can hold at a given temperature — but cold air's maximum capacity is far lower. When that cold, dry air hits skin, it draws moisture from the stratum corneum by osmosis.

Measured effect: Transepidermal water loss (TEWL) increases significantly in winter months. Studies show TEWL 20–40% higher in winter than summer in the same individuals, independent of their skincare routine.

Indoor heating makes it worse

Heated indoor air has extremely low absolute humidity — sometimes lower than desert conditions. A heated room in January can have 20–30% relative humidity, less than the Sahara at 25%. The combination of cold outdoor air stripping moisture from skin when outside, and dry heated air drawing moisture from skin when inside, creates continuous barrier stress throughout winter.

Cold temperature effects

Cold reduces the activity of enzymes responsible for natural ceramide synthesis and desquamation (normal skin cell shedding). Slower cell turnover means dead cells accumulate on the surface — contributing to dullness and texture.

Cold also causes vasoconstriction — reducing blood flow to skin and, over time, making skin look dull and gray compared to summer's naturally flushed glow.

Wind

Cold, dry wind physically disrupts the surface lipid layer and removes it from the skin. Wind chill is not just a temperature measure — it's a literal stripping force on the skin's protective film.

What to change in winter

Upgrade moisturizer richness

The most important winter routine adjustment. A gel moisturizer that worked perfectly in summer is insufficient for winter barrier demands.

The upgrade path:
Summer: Gel or gel-cream (Neutrogena Hydro Boost Gel)
Transition: Gel-cream or light cream (CeraVe PM Lotion)
Winter: Rich cream or balm (CeraVe Moisturizing Cream, La Roche-Posay Lipikar Balm AP+)

Add an occlusive layer at night: In winter specifically, petrolatum (Vaseline) applied as a thin film over your rich cream provides maximum TEWL reduction overnight. The "slugging" practice is most impactful in winter.

Switch to cream cleanser or reduce cleansing

Foaming cleansers that worked fine in summer may over-strip in winter when ceramide levels are already lower. Options:
Switch from foaming to cream or hydrating cleanser for the AM wash
Reduce AM cleansing to a water rinse only (especially for dry skin types)
Evening cleanse stays full (SPF and makeup removal required year-round)

Reduce exfoliation frequency

Winter skin is already turning over more slowly and is more barrier-compromised. Maintaining summer exfoliation frequency (3–4x per week AHA/BHA) often causes winter sensitivity and redness.

Winter adjustment: Drop to 1–2x per week exfoliation. If significant sensitivity develops, pause completely for 2 weeks, repair the barrier, and reintroduce at lower frequency.

Maintain retinoids — but buffer more

Don't stop tretinoin or retinol in winter — the anti-aging and acne benefits are year-round. But the drier, more compromised winter skin tolerates retinoids less well.

Winter retinoid strategy:
Apply a layer of ceramide moisturizer before retinoid (buffer sandwich technique)
Follow with another layer of moisturizer after
If irritation increases significantly, reduce frequency (every other night instead of nightly) rather than stopping

Don't skip SPF

UVA penetrates clouds and glass year-round. Winter doesn't reduce photoaging risk meaningfully (UVA, the primary photoaging driver, is relatively constant across seasons; UVB that causes sunburn is lower in winter but UVA remains). Snow also reflects UV — skiers and snowboarders face increased UV exposure.

Compliance drop in winter is the main risk. If your summer SPF is too heavy for winter, find a lighter texture (EltaMD UV Clear SPF 46 or similar) that doesn't feel occlusive on already-covered winter skin.

The winter barrier repair protocol

For skin that has already become significantly dry, red, or sensitive from winter:

Phase 1 — Pause and repair (1–2 weeks):
Stop all exfoliants (AHAs, BHAs)
Stop retinoids temporarily
Stop vitamin C (L-ascorbic acid at pH 3 is an irritant for compromised barrier)
Routine: gentle cream cleanser → ceramide moisturizer → occlusive layer at night → mineral SPF in the morning

Phase 2 — Gradual reintroduction:
Once skin is comfortable and no longer tight or reactive, reintroduce one active at a time:
Restart retinoid first (every third night) with heavy moisturizer buffering
After 2–3 weeks stable: add BHA 1x per week
After another 2 weeks: assess whether additional actives are needed

Phase 3 — Winter maintenance routine:
Cleanse with cream/hydrating formula
Hyaluronic acid serum on damp skin
Ceramide-rich cream
Petrolatum occlusive at night
Retinoid 3x per week (reduced from summer frequency if needed)
SPF daily

Specific winter skin concerns

Hands

Hands have even fewer sebaceous glands than the face — they dry out fastest in winter, particularly with repeated handwashing. The skin on the backs of hands has no sebaceous glands at all.

Protocol: Apply hand cream immediately after every handwash. Keep it at the sink. Overnight treatment: thick layer of hand cream + cotton gloves for severely cracked or eczematous hands.

Best hand creams for winter: Neutrogena Norwegian Formula (glycerin concentrate; the gold standard for cracked hands), O'Keeffe's Working Hands (intensive; long-lasting occlusion), Curel Hydra Therapy (applied to wet skin before drying; unique delivery mechanism).

Lips

Lips have no sebaceous glands and a very thin or absent stratum corneum — they suffer dramatically in winter. Consistent petrolatum application is the most effective prevention.

Protocol: Aquaphor or plain Vaseline on lips overnight; EltaMD UV Lip Balm SPF 36 during the day. Stop flavored balms that encourage licking.

Feet and heels

Heel fissures (cracked heels) are a winter-specific phenomenon in many people. Thick keratin on the heel combines with dryness and constant pressure to create deep fissures.

Protocol: Urea 25–40% cream (Flexitol Heel Balm, CeraVe Healing Ointment) applied nightly with socks. Pumice stone before application. For very deep fissures: consult a dermatologist or podiatrist.

Eczema

Atopic dermatitis predictably worsens in winter — the low humidity reduces ceramide production further in already ceramide-deficient skin. Existing eczema patients should:
Increase ceramide moisturizer application frequency to 3x daily during winter flares
Use a humidifier in the bedroom (target 45–55% RH)
Reduce bathing temperature
Have prescription topical steroids or Dupixent ready for flares

The humidifier: most underrated winter skin tool

A bedroom humidifier running during sleep significantly reduces the nocturnal TEWL that dry heated air causes. Target 45–55% relative humidity in the sleep environment.

Practical options:
Ultrasonic humidifiers: quiet; efficient; require regular cleaning to prevent mold
Cool-mist evaporative: self-regulating humidity; slightly noisier
Avoid hot-steam vaporizers near skin (burn risk; less practical)

For patients with severe winter dryness or eczema, a humidifier often produces more improvement than any additional product purchase.

What not to do in winter

Switch to heavier everything: Some heavy, occlusive formulas are comedogenic for acne-prone skin. Upgrade moisturizer richness selectively — richer on dry areas (cheeks, hands, lips), not necessarily heavier on oily T-zones.

Skip cleanser entirely: The minimal viable winter cleanse is still a real cleanse in the evening to remove SPF and daily pollutants. Sleeping in the day's debris is not a winter shortcut.

Hot showers for warmth: The skin cost is high. Keep shower temperature comfortable but not hot even in winter — the ceramide stripping from a hot winter shower is worse than in summer because winter skin has fewer ceramides to spare.
