Dry and dehydrated skin: what are the differences?

Dry skin: what is it?

Dry skin, also known as ‘cutaneous xerosis’, is a condition where the skin doesn't produce enough natural oil or sebum.

Decreased sebum weakens the skin's lipid barrier. This also leads to an increase in the permeability of the stratum corneum, allowing irritants to penetrate more easily which is more likely to result in feelings of skin discomfort more often.


What is dehydrated skin?

Dehydrated skin is characterised by a lack of water in its superficial skin layers, mainly in the epidermis. This often stems from the skin's inability to retain water on its own. The hydrolipidic film, made up of sebum and water, which acts as a protective barrier, is thus altered. This increases transepidermal water loss, leading to skin dehydration.

What is the cause?

Skin dryness and dehydration have different causes.

Environmental factors: climatic changes, such as cold, lack of humidity, wind, high temperatures and chronic exposure to the sun, contribute to water evaporating from the epidermis, encouraging dehydration. Hard water is also a factor in skin dehydration. By accumulating on the skin, limescale forms a barrier that reduces the skin's ability to absorb and retain water. This water loss contributes to skin dryness. Similarly, the build-up of limescale prevents the naturally-occurring sebum from being properly distributed, weakening the hydrolipidic barrier.

Poor skincare routine: dry skin can be caused by the use of harsh cleansing products, such as alkaline soaps, certain surfactants and bubble baths. Applying the wrong skincare routine also removes oils and sebum from the skin, making it drier.

Hormonal variations: last but not least, skin ageing and hormonal variations, particularly during the menopause, cause a drop in oestrogen levels. This hormonal decline has an indirect impact on sebum production and skin thickness, amplifying the sensation of dryness and causing more signs of ageing.

Lack of hydration: not drinking enough water can have a direct impact on the skin and serum production. That's why it's important to drink at least 1 litre of water a day, which can also include supplements in it.

Genetic factors: don't forget heredity, as some people have naturally dry skin because they produce less sebum. In fact, you need to follow an appropriate skincare routine to provide your body and skin with enough water.

What are their characteristics?

Dry skin: symptoms

  • No shiny, open pores: particularly on the face's T-zone.

  • Uncomfortable: dry skin can cause feelings of tightness, tingling and itching, particularly in dry, cold weather.

  • Dry or rough to the touch

  • it often has a cracked appearance : patches of dryness reminiscent of snakeskin or dead skin.

  • The skin is thinner: it tends to wrinkle easily, especially around the eyes, and can look older.

Dehydrated skin: symptoms

  • Dull complexion: the skin is tight and superficial fine lines of dehydration in the thinner areas may appear.

  • Increased sensitivity : the skin shows occasional redness and appears more sensitive.

  • Signs of roughness or uneven complexion may appear: the skin may also retain its shine, particularly in the T-zone.

What categories of dry skin are there?

Facial dryness can be classified into three stages, depending on the severity of the symptoms.

Mild dryness: this stage is characterised by mild dryness of the skin, often accompanied by slight itching or tightness. The skin may appear a little dull or dehydrated. There is usually no cracking, chapping or severe redness.

Moderate dryness: at this stage, the symptoms of dry skin are more pronounced. Skin may appear flaky, rough and cracked, and itching may be more intense. There may be redness and irritation.

Very dry skin: this is the most advanced stage. The skin is extremely dry, rough, cracked and even chapped in certain areas, such as the lips. The skin feels itchy and there is a burning sensation. It is advisable to consult a dermatologist if you find yourself in this situation.

Very dry skin: the right daily routine

Here are our tips to help you keep your skin hydrated and avoid the cracked skin effect.

  1. Moisturise regularly: choose products that are rich and moisturising enough to nourish deep down, protect against water loss and relieve the feelings of tightness and discomfort that can occur when skin is too dry. Opt for skincare products that are high in active moisturising ingredients, plant-based oils and butters, as well as phytoceramides.

  2. Avoid "aggressive" products and soaps. Cleansers containing soap or aggressive surfactants can be very drying for the skin. So it's important to choose gentle, superfatted, fragrance-free products. It's also advisable not to take long hot baths or showers as hot water can aggravate the phenomenon.

  3. Drink enough water. Remember that moisurising your skin starts from the inside. Internal hydration is essential to keep the skin supple and avoid dehydration, which exacerbates skin dryness.

  4. Avoid dry environments: saunas, exposure to the sun or other conditions that encourage skin dehydration.

Expert advice on moisturising and nourishing your skin

Carrier oils provide deep moisturisation while reinforcing the skin's natural lipid barrier. Unlike mineral oils, carrier oils are rich in essential fatty acids, vitamins and antioxidants, which play an active role in nourishing and protecting the skin. They also help to create a barrier on the skin's surface, locking in hydration and reducing skin's water loss.

What are the best ways to deal with dryness during pregnancy?

To look after your skin, choose moisturising and nourishing products that are specifically suited to you during pregnancy and breastfeeding. You should particularly avoid essential oils and perfumes, and always check product labels to make sure they are suitable for you. If in doubt, don't hesitate to consult a healthcare professional.

Why is my skin dry even though I moisturise it?

If your skin remains dry despite regular application of moisturisers, there may be several reasons for this:

  • A lack of lipids: dry skin needs to be nourished with fats (oils, butters) to strengthen the skin barrier. Moisturising alone is not enough.

  • Unsuitable products: some skincare products that contain alcohol or are too light may not be rich enough for your skin.

  • A poor routine: aggressive cleansing or excessive exfoliation can damage the skin barrier and make dryness worse.

  • A lack of internal water: dehydrated skin lacks water, so it's essential to drink enough throughout the day.

Adopting appropriate nourishing and moisturising skin care products, cutting down on aggressive cleansing and maintaining good internal hydration are the keys to making your skin feel pleasant again.

What creams and skincare products are needed for oily, dehydrated skin?

Oily skin can also be dehydrated if it lacks water, which can cause tightness and an excess of compensatory sebum. Here are the right skincare products for you:

  • Light moisturisers: choose gels or creams with hyaluronic acid, aloe vera or hydrosols (rose, orange blossom) for extra moisture without weighing the skin down.

  • Non-comedogenic carrier oils: such as jojoba or hazelnut oil, which regulate sebum while locking in moisture.

  • Gentle cleansing: avoid harsh cleansers and opt instead for floral waters or gentle cleansing gels to maintain skin balance.

The aim is to deeply moisturise while regulating sebum for balanced, radiant skin.
