What Causes Dehydrated Skin?

We often think of the summer months as a time when our skin needs less hydration, not more. But that’s a critical mistake. Summer heat, sun exposure, and travel can all contribute to the causes of dehydrated skin and result in dehydration lines, irritation, and oiliness.

Understanding what causes dehydrated skin is the first step towards achieving healthier, more luminous, hydrated skin all season long. That’s why we’re diving deep into the causes and characteristics of dehydrated skin with an in-depth look at this common skincare concern and how to solve it.

Common Causes of Dehydrated Skin

Maintaining a healthy moisture barrier is the key to keeping skin healthy and hydrated. This microns-thin layer of shedding skin cells and lipids repels water, sealing nourishing moisture into the skin. A compromised moisture barrier can cause moisture to evaporate out of skin, causing dehydration.

This can occur due to:

  • Sun exposure
  • Air travel
  • Living or visiting a drier climate
  • Exposure to irritants such as salt water, pool water, or pollution
  • Forced air heating or cooling (aka AC)
  • Using too many skincare actives such as exfoliating acids
  • Stress

5 Characteristics of Dehydrated Skin

So how do you know if your skin is dehydrated? Look for any of these 5 characteristics of dehydrated skin:

  1. Dehydration lines – Wrinkles can form due to dehydration as moisture loss essentially deflates your skin. These dehydration wrinkles can show up anywhere, but are most common around the eyes and on your forehead.
  2. Shiny, oily skin – When your skin becomes dehydrated, the body often compensates by producing more of its natural protective oils – known as sebum – in an attempt to lock in moisture. The result: oily skin.
  3. Congestion – This additional sebum can mix with makeup and impurities, clogging pores.
  4. Irritation – As your skin loses moisture, it can become rough, irritated, and itchy.
  5. Redness – Red, chapped skin is also common when skin becomes dehydrated.

If you’re experiencing any of these skin concerns and suspect your skin is dehydrated, gently pinch one of your cheeks. If it wrinkles with gentle pressure instead of holding its shape, your skin is indeed dehydrated.
