What Causes Dry, Itchy Skin? A Simple Guide to Finding Relief

What causes dry, itchy skin is usually the same frustrating story in different outfits: your skin is losing water faster than it can hold on to it. The reason that’s happening determines the right solution.

So before you throw five random lotions at the problem, consider this: dry skin and itchy skin are connected, but they’re not always caused by the same thing. The goal is to figure out what’s causing your skin to react like it is so you can treat the cause instead of just chasing the itch.

Let’s explore what might be behind your skin troubles and how to get relief.

What Is Dry, Itchy Skin and Why Does It Happen?

Think of your skin like a brick wall. The skin cells are the bricks, and natural oils and moisture are the mortar holding everything together. When the mortar starts to crumble, gaps form, and your skin becomes dry, rough, and vulnerable to irritation.

But why does skin get itchy? When your skin loses moisture, nerve endings near the surface become exposed and irritated. Your boy sends signals to your brain saying, “Something’s wrong here,” which you feel as an itch. Scratching might feel good temporarily, but it actually damages your skin further and can create a vicious cycle of itching and scratching.

5 Things That Cause Dry, Itchy Skin and Their Solutions

The first thing you want to do is pin down what’s causing your dry, itchy skin. Start with a quick scan of your life.

If the itchiness flares up after showers, after you’ve used new products, after exfoliating, or after you’ve been out in the winter air, you may be dealing with barrier stress. If it showed up slowly over the years, aging may be part of it. If it’s intense, patchy, or comes with a rash, you may be dealing with dermatitis or eczema. If it’s stubborn and nothing seems to help it, you may have a vitamin deficiency, thyroid deficiency, or other medical issue.

1. Weakened Outer Barrier

This is one of the most common causes of dry, itchy skin, and it’s also the one that people accidentally make worse while trying to treat it. They may use harsh cleansers, fragranced body washes, scrubs, acids, or too-hot baths and showers that further exacerbate the problem.

The Fix:

1. Take a two-week break. Strip back your skincare routine to only the basics. No exfoliators, scrubs, or fragranced products, and no fancy serums that promise results in 24 hours.
2. Change your showering strategy. Keep showers shorter, use lukewarm water, and cleanse only what truly needs cleansing (underarms, groin, feet). For everything else, water is often enough while your barrier heals.
3. Moisturize immediately. Within a few minutes of your shower or bath, while your skin is still slightly damp, apply moisturizer. That’s when you can trap water in the skin instead of chasing it later. Our Calming Moisture and Body Repair Lotion are excellent options as they will help heal the skin while trapping moisture in, protecting the skin barrier, and restoring skin radiance.
4. Treat itchy skin. When the itch is really bothering you, treat it right away, so it doesn’t get worse. Our Rescue + Relief Spray is a great “interrupt button,” as it can calm itching quickly while replenishing moisture, boosting hydration, and encouraging skin repair.
5. Seal moisture in. This is where you create a protective barrier on your skin while it heals. Our CV Skinlabs Restorative Skin Balm is the kind of product that makes sense when skin feels thin, reactive, or rubbed raw. It’s an occlusive, yet breathable ointment that will help support the barrier while it rebuilds.

2. Dry, Itchy Skin from Aging

Aging skin tends to produce fewer oils, and the barrier recovers more slowly than it did in our youth. That doesn’t mean your skin is doomed—it just means you need a steadier rhythm of moisture and protection than you used to.

The Fix:

1. Moisturize every day. Switch from moisturizing when you remember to moisturizing every day. Make it part of your usual routine, moisturizing after every shower or bath. If you don’t shower that day, moisturize before getting dressed or before going to bed.
2. Moisturize twice a day. Moisturizing more than once a day is often the key to taking care of aging skin. Try applying moisture morning and night, and focus on areas that are bothering you most.
3. Switch to better products. Quality skin care products are important at any age, but as we get older, they become even more critical to maintaining healthy, comfortable skin. Go through all your products and ditch those that you bought simply because they smelled nice or were cheap. Then, seek out better solutions that have clean ingredients, as these will be more likely to keep up with what your skin needs at this age.
4. Build in itch support. Aging skin can itch simply because it’s dry, but once you scratch the irritation gets worse. Keeping our Rescue + Relief Spray around for those moments helps you avoid this problem. It contains ingredients like water lily, oat extract, and beta-glucan that quell itch and help calm, soothe, and heal the skin.
5. Go heavier at night. Your skin works to heal itself while you sleep, so before bed is the perfect time to apply a heavier balm to irritated areas. Our Restorative Skin Balm traps in moisture and helps speed healing and recovery from chronic dry, cracked skin. It’s perfect for hands, elbows, or any area that is giving you extra trouble.

3. Environmental Stress

If your skin gets worse in winter, on airplanes, in heated buildings, or during dry, windy weather, it may be due to environmental stress. Dry air in these areas pulls water out of your skin the same way it dries out a sponge on the counter.

The Fix:

1. Add moisture back into the air. A humidifier in the room where you sleep can make a bigger difference than you may expect.
2. Protect exposed skin. Cold wind and low humidity are a double hit, so gloves and long sleeves aren’t just for comfort—they can provide protection. Hats and scarves are also helpful.
3. Moisturize! Get into moisturizing as a part of your daily routine. Do it before you get dressed, after you brush your teeth, and after your shower. In dry months, lotion becomes maintenance the same way deodorant is.
4. Calm the itch. If your skin gets itchy during the day because the air is stripping it down, Rescue + Relief Spray can calm that prickly, irritated feeling without you needing to re-do your whole routine. You can also re-apply moisture wherever it’s needed.

4. Dry, Itchy Skin from Vitamin Deficiency

Certain vitamin deficiencies are associated with skin problems, including dryness, irritation, and itch, especially vitamins A, B12, D, and E. If your body doesn’t have what it needs to support healthy skin function, your skin can start showing it.

Vitamin B deficiencies, for example, are linked directly to skin disorders. A lack of vitamin B2 (riboflavin) can show up as cracked lips, red skin, and a greasy, scaly rash around the nose and mouth. A vitamin B3 (niacin) shortage may lead to pellagra, causing dark, rough patches, particularly on sun-exposed areas. A vitamin B5 (pantothenic acid) shortage can cause dryness, itching, and an increase in the risk of acne.

Vitamin C is crucial for collagen production, so a deficiency may lead to fragile skin that bruises easily, slow healing of rashes and wounds, and dry, rough patches. Vitamin E products skin from free radical damage, and a shortage may lead to increased skin sensitivity, dryness and flakiness, and dull skin tone.

Finally, vitamin D helps control skin inflammation, and a deficiency may show up as persistent dryness, peeling or scaling, frequent acne breakouts, or unexplained redness.

Keep in mind that skin problems can be caused by a range of issues, so don’t assume a vitamin deficiency is to blame. Get it checked out first.

The Fix:

1. Look for internal clues. Dry, itchy skin paired with fatigue, mood changes, tingling sensations, frequent illness, or slow wound healing may signal a vitamin deficiency.
2. Talk to your doctor. If you suspect a vitamin deficiency may be going on, don’t guess by taking random supplements. Talk with a clinician and ask for blood tests, particularly to check for levels of vitamin D and B12, because both low and overly high levels can cause issues.
3. Treat your skin. Continue to moisturize frequently and calm the itch with our Rescue + Relief Spray. You want to calm the skin as much as possible as you wait for longer-term changes to kick in.

5. Irritating Products

Sometimes the cause of your dry, itchy skin may be sitting in your bathroom cupboard. Fragrance is a common trigger, for instance, as are harsh cleansers, frequent exfoliation with harsh products, and even laundry detergents.

The Fix:

1. Do a simple reset. For 10-14 days, use only gentle, fragrance-free basics and pause anything extra. If your skin calms down, it could be that the problem was coming from your products.
2. Reintroduce them one at a time. Next, reintroduce your favorite products one at a time, every few days, so you can see how your skin reacts. This will help you identify what may be causing the flare-ups of dryness and itchiness.
3. Seek out clean products. If products are causing your skin to dry out and itch, they’re the wrong products for you. Consider getting rid of those with harsh ingredients like alcohol, synthetic fragrance, sulfates, and other ingredients we recommend you avoid. Then, switch to cleaner products with nourishing ingredients that will help your skin recover.
4. Keep itch relief on hand. It’s super important to avoid scratching, so keep our Rescue + Relief handy so you can calm your skin whenever it needs it.

Other Possible Causes of Dry, Itchy Skin

You could have more than one of the above issues causing your dry, itchy skin, so keep an eye out as you experiment to see what your best solution is. For example, you could have a weakened barrier and be dealing with aging skin at the same time, so you may want to combine solutions there for your best results.

It’s also important to consider that if your itching is widespread, severe, paired with a rash that won’t go away, or disrupting your sleep for weeks, it’s worth talking to a dermatologist or family doctor. Sometimes eczema, psoriasis, allergic contact dermatitis, thyroid issues, or other conditions may also be playing a role, and getting the right diagnosis can save you months of trial and error.

Dry, itchy skin can make you feel distracted, uncomfortable, and weirdly self-conscious, but once you match the solution to the cause, skincare usually gets easier. Give your skin a calmer routine, support while it heals, and instant itch relief, and you’ll be on your way.

If you had to guess, which of these causes sounds the most like it may be affecting you right now?
