How To Use A Humidifier For Skin? Benefits And Risks

Written by Anjali Sayee

A humidifier adds moisture to the air, and that is what you need in dry conditions. Lack of moisture in the air (low humidity) impacts your skin negatively. Using a humidifier helps you balance out humidity levels in your room and prevents the skin from becoming dry and rough. This may even help delay the appearance of aging signs like wrinkles, a result of dry skin.

In this article, we further discuss the benefits of using a humidifier for the skin, how it works, which humidifier to choose, and a few tips to use it safely. Keep reading.

Benefits Of Using Humidifiers For Skin

1. Helps Reduce Water Loss From Skin

Low humidity levels compromise the skin barrier function (1). Such weather conditions cause the lipids and oils that bind the skin cells together to evaporate and expose the inner layers of the skin to external hazards. This weakened skin barrier function causes more water to be lost from the skin’s surface, making the skin rough and dry (2). The increased dryness may further lead to dry skin disorders (3).

Besides, a study suggests that fine wrinkles may form on the skin if exposed to low humidity levels for short periods (like 6 hours) (4). A humidifier can balance out low levels of moisture in the air (5).

2. May Help Manage Skin Disorders

Dry air in air-conditioned rooms can worsen skin conditions like senile xerosis (dry skin) and atopic dermatitis (red and itchy skin) besides making the skin rough (6), (7). Humidifiers add moisture to dry air and may keep such skin conditions from aggravating. A study shows that using a humidifier that generates nano-sized water particles may hydrate the skin better, improve the skin barrier function, and reduce transepidermal water loss (8). However, more studies are needed to assess this type of humidifier.

3. May Prevent Bacterial And Viral Infections

Certain bacteria or viruses thrive at both high and low humidity levels. These microorganisms can cause skin infections that deteriorate skin health and quality. Research shows that they are less likely to survive at a relative humidity level of 30 to 60% (5). A humidifier helps balance out the humidity level, preventing the microbes from affecting the skin.

4. May Protect Skin From Irritants And Allergens

As stated, low humidity levels affect the skin barrier function. As a result, irritants and allergens penetrate the skin (1). This may increase the risk of skin diseases and flare-ups in people with atopic dermatitis (red and itchy skin). A humidifier comes in handy by increasing the humidity levels.

What are the types of humidifiers available and how do they work? Let us discuss them in the next section.

Types Of Humidifiers And How They Work

Humidifiers are available in different types. These include:

  • Console humidifiers: Ideal for floor use and are encased in cabinets.
  • Portable humidifiers: Smaller and transportable.
  • Central humidifiers: Built into heating and air conditioning systems. They humidify the entire house.
  • Ultrasonic humidifiers: Create cool mists through ultrasonic sound vibrations.
  • Impeller humidifiers: Have a high-speed rotating disk that produces cool mist.
  • Evaporative humidifiers: Send moisture into the air using a fan to blow out air through a wet absorbent material like a belt or filter.
  • Steam vaporizer humidifiers: Use an electrical heating mechanism to heat water. The warm mist formed is then cooled before exiting the humidifier.

You can choose a humidifier depending on your needs. If you don’t know how to use it for improving your skin, here are some tips.

How To Use A Humidifier To Improve Skin— Tips To Consider

  1. Add water to the humidifier. Use bottled or distilled water as it contains fewer microorganisms and lower mineral content.
  2. Clean the humidifier regularly. It may contain microorganisms or dirt particles that may affect your skin and health. Clean portable humidifiers every third day. Empty the tank and use a brush or scrubber to clean them. Remove any scales, deposits, or film formed on the sides of the tank or on interior surfaces. Wipe all surfaces dry. Be sure to unplug the unit while cleaning.
  3. Do not use the humidifier in all climatic conditions. Use it only to balance out humidity and moisture conditions.
  4. Use demineralized cartridges and filters.
  5. The skin becomes dry and rough at low humidity. Switch on your humidifier before you get into the daily skin care routine. This helps your skin retain moisture for longer periods.

Using a humidifier during the day might improve your skin health. But is it alright to keep it running the entire night as you sleep? Read to know more.

Is Sleeping With A Humidifier Turned On Good For Skin?

Using a humidifier as you sleep is perfectly alright. It might even help you sleep better if you have dry and itchy skin, sinus issues, cold congestions, and cracked lips. Besides, applying your skincare products and sleeping with the humidifier running may promote uninterrupted sleep. It improves skin moisture and may even keep your scalp free of itching or dryness.

It is clear that a humidifier can improve skin health. But it may have some side effects too.

Things To Be Aware Of — Risk Factors

Research shows that the toxicity of biocides (pesticides or fungicides) mixed in the water of humidifiers may cause a particular pulmonary syndrome in pregnant women and children (9). Using a humidifier may also increase the humidity levels, which may support the growth of microorganisms that can cause infections (5). Using humidifiers may also cause thermal discomfort (exposure to either excess heat or excess cold) (6). Water mist sprays can be an effective alternative. They hydrate the skin without the drawbacks of a humidifier.

Stop using a humidifier if you experience any respiratory issues. Contact your doctor immediately.


Using a humidifier will help maintain the skin barrier function and protects the skin from UV rays and excess water loss. It keeps the skin hydrated and reduces the risk of dry skin disorders. Clean the humidifier regularly and use bottled or distilled water as it contains fewer microorganisms. Apply skincare products first and run the humidifier as you sleep. This helps prevent skin dryness, itching, or roughness. However, the toxicity of biocides mixed in the water of humidifiers may cause fatal pulmonary syndrome in pregnant women and children. Hence, take precautions and be well-informed before you purchase a humidifier. Consult a doctor if you face any respiratory issues.
