Dehydrated skin: Causes and how to treat it

Dehydrated skin is a very common, and often misunderstood, skin concern caused by a lack of water in the skin. It can affect all skin types, including oily skin, and is frequently confused with dry skin. Understanding the causes of dehydrated skin, how to recognise the signs, and how to restore moisture effectively is key to keeping skin comfortable, radiant and balanced.

A personalised skincare routine helps address dehydration while respecting your skin type and lifestyle. A skin diagnosis can guide you towards the most suitable hydrating products.


Dehydrated skin causes


Several internal and external factors can lead to dehydration:



-Cold weather, wind or air conditioning

-Sun exposure and heat

-Over-cleansing or harsh formulas

-Hot showers

-Stress, fatigue or lack of sleep

-Not drinking enough water



These factors weaken the skin barrier, increasing water loss and making dehydration more likely.



Signs of dehydrated skin


Common signs of dehydrated skin include:



-Tightness, especially after cleansing

-Dull or tired-looking complexion

-Fine lines caused by dehydration

-Rough texture or dry patches

-Skin that feels uncomfortable despite using moisturiser

-Oily skin with surface dryness



How to treat dehydrated skin


The best dehydrated skin treatment focuses on restoring and retaining moisture while supporting the skin barrier.

1. Use gentle, hydrating formulas

Choose skincare that cleanses without stripping and helps the skin retain water.

2. Layer hydration

Lightweight gels and hydrating serums help replenish moisture at the heart of the skin, even for oily skin types.

3. Lock in moisture

Follow with a body moisturiser adapted to your skin type to help limit water loss throughout the day.

4. Protect the skin barrier

Healthy skin retains moisture more effectively. Look for formulas inspired by plant science that support comfort and balance.

FAQ


What is the difference between dehydrated skin and dry skin?

Dehydrated skin lacks water and is a temporary condition, while dry skin lacks oil and is a skin type. Dehydrated skin needs hydration-focused care, whereas dry skin benefits from nourishing formulas rich in lipids. Skin can be both dry and dehydrated at the same time.

Should I still moisturise if my skin is dehydrated?

Yes. Hydration and moisturising work together. Hydrating products help replenish water in the skin, while moisturisers help lock in that moisture and reduce water loss throughout the day.

Can oily skin be dehydrated?

Yes. Dehydration can affect all skin types, including oily and combination skin. When skin lacks water, it may produce more oil to compensate, leading to shine alongside surface dryness or tightness.

How long does it take to improve dehydrated skin?

With a consistent, well-adapted routine, skin can feel more comfortable and supple quickly. Supporting the skin barrier and maintaining hydration daily helps prevent dehydration from returning.
