21 very surprising reasons for your dry skin and what to do about it

And no, the weather isn't the only factor.

“If you expose your skin to hot water for an extended amount of time, it's more prone to becoming dry, red and itchy,” Rick continues. And before you jump in the tub, “baths can be even worse than showers,."

Sadly, the best solution is to lower the temperature, or keep your hot showers short (around ten minutes). And, if you're having a bath, add a few drops of oil into the water. “Also make sure to only use body soap in the essential areas only (like underarms and groin), and moisturise right after showering,” says Rick.

3. Your room isn't ‘moist’ enough

Central heating in winter, or air-con during summer, can sap the skin of moisture. Charlotte Vøhtz, founder of Green People, advises placing bowls of water near your radiators or windows. Or, invest in a humidifier – this way, moisture will be released back into the air and your skin can benefit. This is especially beneficial in the bedroom, where many of us spend seven to eight hours sleeping.

4. You've ditched eating fruit

The absence of fruit and vegetables can have a detrimental effect on our skin. The UK’s leading nutritionist and author of Natural Alternatives to Sugar, Dr Marilyn Glenville, explains “what we eat has an effect on the mechanisms that are associated with skin ageing.” For instance, “vitamin C helps in the manufacturing of collagen,” which is essential for keeping our skin looking plump, hydrated and healthy. Better start packing an orange for your afternoon snack...

It's worth remembering that nutritional deficiencies in general could be the cause of your dry skin. A diet lacking in certain nutrients, such as essential fatty acids, can also be a contributing factor.

5. Alcohol and caffeine consumption

Both alcohol and caffeine are diuretics and this essentially means that they increase the product of urine. Dr Catherine Carney from Private Addiction Rehab Clinic, Delamere says: “Alcohol is a diuretic, meaning that when consumed, it can cause the body to remove fluids from the blood via the body’s renal system at a faster rate.”

This is why when you're out drinking, you may ‘break the seal’ and need to pass urine more often than normal. The extra production of urine causes the body to lose fluids faster and, as a result, lose moisture - leading to dry, dehydrated skin.

6. Not drinking enough water

An obvious one, but drinking enough water is key for healthy skin. “To really hydrate well, the average person should consume approximately two to three litres of water per day”, says Dr Michael Barnish, Medical Director for REVIV UK. “This is water - not tea, coffee, juice or alcohol - which actually dehydrate the body."

7. Using a moisturiser that's too heavy

If you think you’re solving the problem by diligently layering up your face and body cream, you could be, quite literally, masking the issue. Many of us respond to dry skin by slathering on the heaviest moisturiser we can find. Dr Rekha Tailor, Medical Director of the Health & Aesthetics Clinic, says this can do more harm than good.

“Thick and greasy moisturisers can weaken the skin’s barrier function and alter the skin's natural function of self-hydration. The skin becomes addicted to the use of moisturiser and therefore is unable to regulate itself. It is the skin's own self-regulation that keeps it looking youthful, therefore the need for the skin to self-regulate is extremely important.” Try these:

8. Applying your hyaluronic acid serum all wrong

Hyaluronic acid is the OG of skin hydrators, with a single gram holding up to six litres of water. But there is one caveat: there must be moisture in the air for it to grab onto in the first place.

So if you're slathering hyaluronic acid onto dry skin in a room where the heating is cranked up and humidity levels are low, you could actually be drying out your skin. “Hyaluronic acid will draw moisture from wherever it can find it to hydrate the surface of your face, including the deeper layers of your skin if there is no humidity in the air,” says aesthetic doctor Dr Sophie Shotter.

A good solution is to create a moisture sandwich: spritz on a face mist such as Rare Beauty Always An Optimist 4-in-1 Mist or Biossance Squalane and Hyaluronic Acid Toning Mist; apply your hyaluronic acid serum and top it all off with a ceramide moisturiser to lock hydration into the skin.

9. Skipping SPF

SPF is a year-round requirement for obvious reasons (preventing skin cancer and protecting your skin's DNA). But did you know that UV rays are also incredibly dehydrating for skin that already skews dry, sapping it of water? For this reason make your final layer of skincare a cream-based sunscreen with ingredients such as shea butter, glycerin and hyaluronic acid to restore moisture.

10. Using acne treatments and retinol

Salicylic acid is a core tenet of many on-the-spot products as it unclogs pores and reduces the inflammation that often leads to pigmentation marks. The only downside is that it can be drying, says skin and laser expert, Debbie Thomas, “which may lead to flaking and then irritation, so it is important not to overuse it and to balance active products containing salicylic acid with nourishing ones.”

Flaky red skin is a common side effect of retinol, too, because it speeds up cell turnover and the skin's self-exfoliation. Aesthetic doctor and skin expert Dr Ana Mansouri recommends staggering your retinol usage by “starting gently at a strength of 0.25% to 0.3% and slowly working your way up.” Also look for formulas containing niacinamide to offset the dryness.

11. Not going to bed early enough

No joke, your Netflix addiction could be drying out your skin. As entertaining as Succession is or binging sessions of Love Is Blind, limit your episodes and make sure you hit the hay early for the sake of your skin's rejuvenation.

Lack of sleep causes pH levels to drop and skin becomes unable to produce the moisture it needs. “Getting your eight hours a night promotes a healthy lifestyle, enabling your body to rest properly and your skin to repair each day,” says Dora Walsh, Registered Nutritionist at BANT.

“If you’re finding it hard to sleep, you can help your body to drift off by following some key rules,” she continues. “Make sure you don’t eat too late or drink coffee post-lunch or alcohol. And make time to unwind and take a screen break before getting into bed.”

12. Over-washing without moisturising immediately after

Ever since the pandemic (unlocks sad but core memory), we’ve all naturally became accustomed to washing our hands and body more frequently, with many of us opting for harsher, antibacterial products and hand sanitisers laced with high percentages of alcohol.

Granted, washing hands frequently (and despite any particular virus), should be a habit we rightly become accustomed to – just don't forget to moisturise afterwards and, where possible, look for a hand wash and hand sanitiser that also contains hyaluronic acid. Good options include This Works Stress Check Clean Hands and Hand Shield.

13. Exposure to harsh chemicals

Exposure to harsh chemicals such as chlorine in swimming pools or chemicals in cleaning products can also cause dryness and irritation on the skin because these chemicals can disrupt the natural barrier function of the skin, leading to moisture loss and dryness.

Make sure to use protective clothing and gloves when handling chemicals, and avoiding prolonged exposure to these substances. In the case of unavoidable exposure such as, chlorine in swimming pools, use gentle, moisturising skincare products that can help repair the skin's barrier and replenish moisture loss.

14. Using fragranced products

Fragrance can irritate skin, causing cracked, sore patches to bloom across the body. While synthetic fragrances are often blamed for this reaction, allergic contact dermatitis can also be triggered by essential oils, which, according to skincare expert Paula Begoun, “impart scent through a volatile reaction, which can sensitise the skin.” If this is the case, try Paula's Choice Calm Mineral Moisturizer and Drunk Elephant Lala Retro Whipped Cream, both of which are fragrance free.

15. Certain medical conditions

Skin issues such as psoriasis and eczema can make your skin more prone to dryness. Seemingly unrelated conditions such as diabetes and lupus can also affect blood circulation to the hands, limbs and other body extremities, which increases the risk of dry, cracked and irritated skin.

If you're worried that your dry skin is the result of something more serious, speak to your GP who can find the most appropriate treatment for you.

16. Certain medications

Medical drugs, as we know, can always carry side effects and dry skin is a relatively common one. Some medications, such as diuretics, antihistamines, and antidepressants, can cause dehydration by increasing urine production or reducing fluid retention in the body, which leads to dehydration and can consequently turn the skin dry and flaky.

Other medications, such as retinoids, isotretinoin, and some chemotherapy drugs, can also affect the skin's natural oil production, which can also lead to dryness. These medications can reduce the production of sebum (the natural oil produced by the skin) – which helps to keep the skin moisturised and protected – so in turn, can make skin dryer.

To prevent dry skin caused by medications, it is important to speak with a healthcare professional about the potential side effects of any medications being taken.

17. Not exfoliating enough

There's a delicate line between over exfoliating in winter and not buffing enough. In winter, skin gets extra dry so there's an accumulation of dead cells on the skin's surface. If you fail to remove them, they act as roadblocks to the hydrating serums and moisturisers that you're applying. Better still, exfoliation signals to the deeper layer of skin to ramp up new cell production, which adds to its juicy glow.

18. Using harsh soaps, cleansers and hard water

Using harsh soaps or cleansers can cause dry skin because they can strip away the natural oils and moisture from the skin. The outer layer of the skin contains natural lipids and fatty acids that help to maintain the skin's barrier function and prevent moisture loss. But by using those harsh soaps and cleansers, you can actually disrupt this barrier function by removing them, which can leave the skin feeling tight, dry, and irritated.

It's also worth taking into consideration if your home taps carry hard water. Hard water is packed with minerals like calcium and magnesium, and although they sound great, in excess they can actually disrupt your skin barrier. They can team up to strip away your skin's natural oils and ultimately leave skin feeling very dry.

19. Hormonal changes

Fluctuations in hormones, particularly during puberty, pregnancy or menopause, can cause changes in the skin's oil production, leading to dryness. For example, the menopause can cause a decrease in oil production which can lead to dry skin and other related symptoms like itchiness and flakiness. It can also reduce moisture retention. This can also occur during pregnancy, where hormone levels can cause the skin to become less effective at retaining water, leading to dryness.

20. Genetics

Some people may be more prone to dry skin due to genetics. Genetics can play a role in causing dry skin because some individuals may inherit genes that affect the structure and function of the skin's natural barrier. Research has shown that some individuals may have genetic variations that affect the composition and function of the skin's barrier, making it more susceptible to dryness and other related symptoms.

For example, some individuals may have genes that cause them to produce less natural oils, which can contribute to dry skin. While some of us are born with genes that make us more prone to health conditions that cause dry skin, such as allergies, eczema, diabetes and kidney disease.

21. You're simply ageing

Skin undergoes a lot of changes in our 30s as its repair system slows down. One knock on effect is drier skin, which is also exacerbated by a steady decline in oestrogen – “a hormone that contributes to hydration and collagen levels,” adds Dr Mansouri. To compensate for a decrease in the amount of oil your skin produces, make sure your diet includes foods rich in omega fatty oils –like salmon, mackerel, walnuts and flaxseed oil. Also, look for skincare products containing barrier-building ceramides.
