Dry Skin
Dry skin is skin that has lost the oils and water it needs to stay soft and sealed. It looks dull or flaky, feels tight, and often itches. Most of it improves within a couple of weeks with a change in washing habits and a good moisturizer, though stubborn cases sometimes point to another condition underneath.

What is it?
Top things to know about Dry Skin
- The skin lacks hydration. Xerosis means the outer skin cannot hold adequate water.
- The barrier holds moisture. Natural water-binding substances and lipids help retain water; when disrupted, skin feels tight, rough, flaky or itchy.
- It is not about drinking water. Dry skin is not simply proof that someone is drinking too little.
- Moisturizers work two ways. Humectants such as glycerin attract water, while occlusives such as petrolatum reduce evaporation.
What it looks like
What Dry Skin looks like
Dry skin feels tight, rough and sometimes itchy. It may look dull, flaky or scaly, and in more severe cases, fine cracks appear, giving a cracked or crazy-paving look. It is most common on the lower legs, arms, hands and sides of the trunk. Dry skin is often worse in winter, with hot showers, harsh soaps and aging, as the skin makes less oil.
Where it shows up
Dry skin often affects the arms, lower legs and hands; it can occur more widely.
Arms
Locations along the forearms.
Hands and wrists
Hand, finger or wrist locations.
Lower legs
Locations on the lower legs.
On different skin tones
Dry Skin on different skin tones
On lighter skin, dry skin may look pink, flaky or dull. On brown and Black skin, it often looks gray or ashy, which makes dryness very visible. Regular moisturizing usually restores the skin's normal look on every skin tone.
What happens in Dry Skin?
The outer skin does not retain enough water when its barrier becomes less effective. Changes in skin fats and moisture reduce flexibility and can lead to roughness, flaking or cracks.
- Less moisture is retained: The outer layer loses its flexibility.
- The barrier becomes less effective: Changes in skin fats allow more water loss.
- Flaking and cracks appear: Dry surface cells shed unevenly.
Causes and triggers
What causes Dry Skin
Causes
Why it happens
Dry skin happens when the skin loses water faster than it can hold it, usually because its outer barrier is weakened.
Some people inherit a weaker barrier, often linked to eczema.

Daily care
Daily care for Dry Skin
Moisturize on damp skin
Within three minutes of the shower.
Cream or ointment, not lotion
Lotions are mostly water.
A gentle, fragrance-free cleanser
Only where it is needed.
Shorter, cooler showers
Five to ten minutes, warm not hot, once a day.
Ointment under gloves overnight
Apply a plain ointment and use comfortable gloves to protect dry hands overnight.
A humidifier in the bedroom
Works on the air, not the skin.
Wear gloves
For washing up, cleaning and cold weather.
Take an oatmeal bath
Modest relief for itch, gentle on broken skin.
Cold rather than hot for itch
A cool compress settles itch; a hot shower worsens it.
Keep nails short
Limits damage while the barrier rebuilds.
Avoid: Long, hot showers and baths
Heat dissolves skin oils.
Avoid: Bar soap and foaming cleansers
Squeaky skin means the oils went.
Avoid: Washing the whole body every day
Water alone suffices for limbs and trunk.
Avoid: Indoor heating and air conditioning
Dry air pulls water out.
Avoid: Wind and cold air on exposed skin
Faces, hands and lips go fastest.
Avoid: Scrubs, loofahs and brushes
Strips the barrier holding water in.
Avoid: Alcohol-based toners and witch hazel
They remove the little oil left.
Avoid: Strong actives on dry skin
Retinoids, acids and benzoyl peroxide increase water loss.
Avoid: Fragranced products on cracked skin
Cracks let fragrance deeper.
Avoid: Scratching and rubbing
Damages the layer holding water in.
Avoid: Wool and rough fabrics
An irritant on skin that lost its cushion.
Avoid: Waiting to moisturize
Cream on damp skin traps water already there.
Avoid: Stopping as soon as it looks better
The barrier rebuilds slower than flaking clears.
Treatments
Treatments for Dry Skin
A thick, fragrance-free cream
A cream or ointment from a tub, not a lotion from a pump — lotions are mostly water and evaporate. Put it on damp skin within three minutes of the shower, and again before bed. Timing matters more than which one you buy, and several of the most effective are inexpensive drugstore creams. Give any of them two weeks before deciding.
Hydrocortisone 1%
A few days of over-the-counter steroid cream can break the itch-scratch cycle when dry skin has turned red and itchy and moisturizer alone is not holding it. Use it twice a day for no more than a week, on the itchy patches only, with the moisturizer continuing around it. If you need it repeatedly, that is a reason to be seen rather than to keep buying it.
Urea
The best choice for thick, scaly skin on heels, shins and elbows, because it softens and dissolves the scale as well as holding water. Ten to twenty percent for general dryness, forty percent for hard heel skin. It is the alternative to scrubbing, which removes the barrier along with the flakes. It stings on cracked or broken skin, so heal the cracks first.
Petrolatum
The most effective sealer there is, cutting water loss from the outer layer by more than any other single ingredient. It works best as the last step over a cream, and under cotton gloves or socks overnight it does more for cracked hands and heels in three nights than a cream does in three weeks. It is greasy, which is the only real objection to it.
Ceramides
Ceramides are part of the fatty glue that dry skin has lost, so a cream containing them replaces the actual missing material rather than just covering it. They are the ingredient with the most evidence behind them for rebuilding the barrier over weeks, and they are the reason certain inexpensive drugstore creams are recommended so often. They are slow rather than dramatic, and they belong in your everyday cream.
Glycerin
Pulls water into the outer layer and holds it there, which is why almost every good moisturizer has it high on the list. It works best paired with something that seals, such as petrolatum or dimethicone, because water drawn in with nothing over the top simply leaves again. In very dry indoor air, glycerin alone is not enough.
Lactic Acid
Loosens stuck-together flakes chemically and draws water in at the same time, so it suits rough, bumpy dryness on the arms and legs. It is gentler than urea on large areas but stings more on cracks and on freshly shaved skin. Use it two or three times a week alongside a plain cream, not instead of one.
Colloidal Oatmeal
A lukewarm oatmeal bath gives modest but genuine relief from the itch, and it is gentle enough for broken and cracked skin, which most itch treatments are not. Ten to fifteen minutes, then straight into a cream on damp skin. It settles the itch for a few hours; it does not repair the barrier that caused it.
Dimethicone
A silicone that forms a breathable seal over the skin, so it holds water in without the greasiness of petrolatum. That makes it the practical option for hands during the day and for anywhere clothes have to go straight back on. It seals but replaces nothing, so it works best in a cream that also contains ceramides or glycerin.
Hyaluronic Acid
Holds a great deal of water, which makes skin look plumper straight away, but it seals nothing. In dry indoor air or a cold winter it can pull water up out of the deeper skin and let it evaporate, leaving the surface tighter than before. It is only useful here applied to damp skin with a cream over the top.
Squalane
A light oil that is close to one the skin makes itself, so it sits comfortably on the face and rarely causes spots. It softens and adds a little seal. It replaces very little of what dry skin has actually lost, so it works as a finishing layer over a ceramide cream rather than as the moisturizer itself.
Shea Butter
Rich and pleasant on ashy shins and elbows, and thick enough to stay where it is put. It seals reasonably well and replaces some fatty acids, but it does not contain the ceramides the barrier is short of. Unrefined versions carry a natural scent that can irritate cracked skin, so a fragrance-free formulation is the safer pick.
Coconut Oil
It seals reasonably and it feels good, and that is most of what it does. It replaces very little of what the skin lost, it clogs pores in some people, and on the face and back it can cause spots. If you like it, use it over a cream rather than instead of one — it is a lid, not a repair.
Triamcinolone Acetonide
A mid-strength steroid ointment for dry skin that has tipped into inflammation — the red-cracked plates of asteatotic eczema on the shins, or thickened patches that are being scratched nightly. Two weeks usually settles it, and the moisturizer carries on underneath and afterward. It is not for plain dryness, and it is not for open cracks or anything that might be infected.
Desonide
A gentler steroid used where the skin is thin or the person is small — the face, the eyelids, the neck, the folds, and children. It suits a child whose dry skin is itchy enough to wake them, alongside a heavy ointment. Short courses only, and the aim is always to get back to moisturizer alone.
Mupirocin
An antibiotic ointment for a single cracked fingertip or heel that has become yellow-crusted and sore. It treats the infection sitting in the crack, not the dryness that opened it, so the cream and the ointment both continue. If redness is spreading up the limb, this is not enough and antibiotic tablets are needed instead.
Outlook
What to expect with Dry Skin
Dry skin slides predictably if nothing changes, and reverses predictably once it does. Most people notice a difference within days, flaking settles in one to two weeks, and cracks on hands and heels take several weeks. The pattern is seasonal - maintenance, not a course.
- 1
Stage 1 · Tight
The skin feels tight after washing and looks slightly dull. Nothing shows to anyone else. The stage most people ignore.
- 2
Stage 2 · Flaking
Fine white or gray scale shows up. Moisturizer works but wears off within a day.
- 3
Stage 3 · Itching
Worst at night and after a hot shower. Scratch marks appear, and the skin looks inflamed as well as dry.
- 4
Stage 4 · Cracking
The skin breaks into a fine network of cracks. On the shins this can become the red-bordered, cracked-porcelain pattern of asteatotic eczema. Cracks here can be deep and painful.
- 5
Stage 5 · Infected
A crack breaks the skin. Yellow crust, spreading redness, warmth, swelling or pus mean a bacterial infection needing treatment.

When to seek care
Seek help if dryness persists despite moisturizers, itch disrupts sleep or the skin cracks and becomes infected. Sudden widespread dryness may need assessment for another cause.
Lookalikes
What else could it be?
Eczema
Plain dry skin is often spread evenly across areas such as the shins. Eczema forms itchier patches that flare repeatedly in the same places.
Psoriasis
Psoriasis usually has thick scale and a clear border you can trace. Plain dry skin has finer flakes and no distinct raised patch underneath.
Ringworm
Ringworm usually makes a round patch that grows outward from a scaly edge. Ordinary dry skin is more evenly spread, often on both sides.
Questions
Questions you might be asking.
Will drinking more water help my dry skin?
Not in any way you will notice, unless you are genuinely dehydrated. The water content of the outer layer depends on how well it seals itself, not on how much you drink. Fix the seal - shorter warm showers, a gentle cleanser, a cream on damp skin.
What is the best moisturizer?
No single best one, and the ones with most evidence are usually inexpensive. Look for a fragrance-free cream in a tub with ceramides and glycerin, plus petrolatum or dimethicone. Applying it to damp skin twice a day for two weeks matters more than which one.
Why is my skin itchy at night?
Several things line up in the evening. Body temperature rises, a warm shower has just stripped the skin, nothing distracts you, and scratching in your sleep goes unchecked. Moisturizing before bed, a cool bedroom and a humidifier all help.
Is dry skin the same as eczema?
No, though they overlap. Dry skin is a state the skin is in. Eczema is a condition where the skin is inherently leaky and inflamed, with itchy, poorly defined patches that come and go, usually from childhood and often with asthma or hay fever. Dry skin that keeps turning red or weeping in the same places is worth a look.
Should I be exfoliating the flakes off?
Not with a scrub. Scrubbing removes the barrier with the flakes and the dryness returns worse. For thick scale on heels, shins or elbows, a cream with urea or lactic acid softens it.
Can dry skin be a sign of something serious?
Usually not. But an underactive thyroid, kidney disease, diabetes and some medicines cause it, and generalized itch without a rash occasionally reflects a problem elsewhere. Worth checking is dryness or itch that starts suddenly in an adult, covers the body, disturbs sleep, or comes with fatigue or weight change.
