Dry Skin (Xerosis) Treatment in Danville, CA

Dry Skin Treatment in Danville, CA

Dry skin, or xerosis, happens when the skin loses too much water and its protective barrier becomes less effective. It can cause roughness, flaking, tightness, itching and cracks that sometimes bleed. Many cases improve with short warm showers, gentle fragrance-free cleansing and frequent use of a cream or ointment moisturizer. Persistent or severe dryness should be evaluated because eczema, psoriasis, medications and systemic health conditions can also cause very dry skin.

Dry skin happens when your skin loses more water than it can hold on to, and the protective layer on the outside stops working properly. It feels rough and tight, it flakes, it itches, and it can crack deeply enough to bleed. Most of it improves with short warm showers instead of long hot ones, a gentle fragrance free wash, and a thick moisturiser used often. If it will not settle, or if it is severe, get it looked at, because eczema, psoriasis, some medicines and some internal illnesses all cause very dry skin too.

What does excessively dry skin look and feel like?

What does very dry skin look and feel like?

Dry skin can range from mild tightness and fine flaking to painful fissures. The more the barrier is disrupted, the more likely the skin is to itch, sting, crack or become inflamed.

It ranges from mild tightness and a bit of flaking through to painful splits. The more damaged the protective layer, the more likely the skin is to itch, sting, crack, or become inflamed.

What causes dry skin?

What causes it?

Dry skin develops when water is lost from the outer skin barrier faster than it can be replaced. Environment, washing habits, work exposures, age, medications and skin or systemic disease can all contribute.

Water leaves the outer layer of your skin faster than it can be replaced. The weather, how you wash, what you handle at work, your age, your medicines, and skin or internal conditions can all play a part.

Low humidity / indoor heatingIncreases water loss from the skinCold winter air, dry climates, heated indoor air
Long or hot bathingRemoves surface lipids and increases barrier disruptionLong hot showers, frequent soaking
Harsh cleansers or solventsStrip protective oils and irritate the barrierStrong soaps, detergents, fragrances, cleaning chemicals
Frequent handwashing or wet workRepeated wet-dry cycles damage the barrierHealthcare, hairstyling, food service, cleaning
AgeSkin produces less oil and retains moisture less efficientlyDryness becomes more common with age
Skin/medical conditionsInflammation or systemic disease can cause persistent xerosisAtopic dermatitis, psoriasis and certain internal medical conditions

Dry air and indoor heating Pulls water out of your skin. Cold winter air, dry climates, and heated rooms.
Long or hot baths and showers Strip the natural oils off the surface. Long hot showers, and soaking.
Harsh soaps and chemicals Take the protective oils away and irritate the skin. Strong soaps, detergents, perfumes and cleaning products.
Washing your hands all day, or wet work Wet, dry, wet, dry damages the barrier. Common in healthcare, hairdressing, catering and cleaning.
Getting older Skin makes less oil and holds water less well, so dryness becomes more common.
Skin and medical conditions Eczema, psoriasis, and certain internal illnesses can all cause dryness that will not shift.

What is the best daily routine for dry skin?

What is the best daily routine?

The most effective routine is usually simple: limit hot water, cleanse gently and apply a thick fragrance-free moisturizer while the skin is still slightly damp. Repeat moisturizer whenever the skin feels dry.

The routine that works is usually the simple one: keep the water warm rather than hot, wash gently, and put a thick fragrance free moisturiser on while your skin is still slightly damp. Reapply whenever it feels dry.

Which moisturizer ingredients can help?

Which ingredients actually help?

The best moisturizer is one you can tolerate and use often. Dermatologists may recommend humectant and barrier-supporting ingredients such as glycerin, urea, lactic acid, ceramides, dimethicone or petrolatum depending on the location and severity.

The best moisturiser is the one you can put up with and will use often. Skin doctors tend to recommend ingredients that pull water in and ingredients that seal it there: glycerin, urea, lactic acid, ceramides, dimethicone or petroleum jelly, depending on where it is and how bad it is.

HumectantsGlycerin, urea, lactic acid, hyaluronic acidHelp attract and hold water in the outer skin layer
Barrier-supporting emollientsCeramides, dimethicone, oilsHelp smooth and support the skin barrier
OcclusivesPetrolatum and ointment basesReduce water loss; especially useful for very dry or cracked areas

Ingredients that pull water in Glycerin, urea, lactic acid, hyaluronic acid. They draw water into the outer layer and hold it there.
Ingredients that repair the barrier Ceramides, dimethicone, and various oils. They smooth the surface and rebuild the barrier.
Ingredients that seal it in Petroleum jelly and ointment bases. They stop water escaping, and they are particularly useful on very dry or cracked areas.

When is dry skin more than a simple moisture problem?

When is it more than just dryness?

Dryness that persists despite good skin care or comes with a rash, severe itch, widespread scale, deep fissures or recurrent infection may be caused by an inflammatory skin disease or another medical condition.

Dryness that will not shift despite good skin care, or that comes with a rash, severe itching, widespread scaling, deep splits, or repeated infections, may be caused by an inflammatory skin condition or by something else going on medically.

Who should consider a dermatology visit?

Who should come in?

A dermatology visit is useful when dry skin is persistent, severe, painful, sleep-disrupting, recurrent or difficult to explain. It is also important for people whose work exposures or medical conditions make skin-barrier damage harder to control.

Come in when the dryness will not go, when it is severe or painful, when it keeps you awake, when it keeps coming back, or when nobody can explain it. Also come in if your job or a medical condition makes it harder to keep on top of.

What treatment might a dermatologist add?

What else might a skin doctor add?

Treatment depends on the cause. A dermatologist may recommend a targeted moisturizer, keratolytic ingredient, short course of anti-inflammatory medication or treatment for an underlying condition. The goal is to heal the barrier and stop the cycle of itch and scratching.

It depends what is causing it. It might be a particular moisturiser, an ingredient that lifts the scale, a short course of something to calm inflammation, or treatment for whatever is underneath. The aim is to heal the barrier and break the itch and scratch cycle.

OUR APPROACH
For persistent dry skin, I would first simplify the routine before adding more products. Hot water, fragrance, scrubs and repeated cleanser can keep the barrier injured even when a patient is moisturizing. If the skin still does not improve, that is when I look more closely for eczema, psoriasis, contact dermatitis or an internal contributor.
For dry skin that will not shift, I would simplify the routine before adding anything to it. Hot water, perfume, scrubs and washing over and over can keep the barrier damaged even while someone is diligently moisturising. If it still does not improve, that is the point at which I start looking harder for eczema, psoriasis, a reaction to something, or an internal cause.
COMMON QUESTIONS

Questions patients ask

Is dry skin the same as eczema?

Is dry skin the same as eczema?

No. Dry skin can occur by itself, while eczema is an inflammatory skin condition that often includes dryness. Persistent itch and rash may need a dermatology diagnosis.

No. Skin can be dry on its own. Eczema is an inflammatory condition, which usually includes dryness but is more than that. Itching and a rash that will not settle need a proper diagnosis.

Should I use lotion, cream or ointment?

Lotion, cream or ointment?

For very dry skin, creams and ointments generally moisturize more effectively than thin lotions. The best choice depends on body area, skin type and comfort.

For very dry skin, creams and ointments work better than thin lotions. Which suits best depends on the part of the body, your skin, and what feels tolerable to use.

Can hot showers make dry skin worse?

Do hot showers make it worse?

Yes. Long, hot showers can strip protective lipids and worsen water loss. Warm water and shorter bathing are usually better.

Yes. Long hot showers strip the protective oils and let more water escape. Warm water, and shorter showers, are better.

What does “fragrance-free” mean?

What does fragrance free mean?

For sensitive or dry skin, fragrance-free products are generally preferred because fragrance can irritate the barrier. “Unscented” can still contain masking fragrance.

It means no perfume has been added. Perfume irritates dry and sensitive skin, so fragrance free is the safer choice. Watch out for unscented, which can still contain a masking perfume.

Why does my dry skin itch so much?

Why does it itch so much?

Barrier damage allows more water loss and irritation, which can trigger itch. Scratching then damages the barrier further, creating an itch-scratch cycle.

A damaged barrier lets more water out and more irritants in, and that sets off the itch. Scratching then damages the barrier further, which makes it itch more. That cycle is the problem.

Can dry skin get infected?

Can dry skin get infected?

Yes. Deep cracks and scratching can break the protective barrier, allowing bacteria to enter. Increasing pain, warmth, pus, spreading redness or fever needs medical attention.

Yes. Deep cracks and scratching break the skin open and let bacteria in. Increasing pain, warmth, pus, spreading redness or a fever needs medical attention.

If this is a medical emergency, call 911. For an urgent skin problem during office hours, call the practice on (925) 820-3376 rather than using a form, messages are not monitored continuously.
