Dry vs. Dehydrated Skin: What’s the Difference + Why It Matters for Your Moisturizer

If your skin feels tight, flaky, or dull, your first instinct may be to use the thickest moisturizer you can find. However, dry skin and dehydrated skin are not the same thing, and knowing the difference is important when putting together a skincare routine.

If you’ve been trying endless moisturizers without seeing the desired results, this guide will help you understand the difference between dry and dehydrated skin, why it matters, and tips on finding the right moisturizer for your unique skin concerns.

What Is Dry Skin?

Dry skin is a skin type caused by a lack of natural oils, (also called sebum) produced by the sebaceous glands. If you have dry skin, it means there’s a lack of lipids to lock in moisture and protect the skin’s barrier

Common Signs Of Dry Skin

  • Flaky or rough texture
  • Small pores
  • Dull or ashy appearance
  • Skin tightness, especially after cleansing
  • Visible fine lines

How To Care For Dry Skin

If you have dry skin, products that restore the skin’s natural barrier are the best. Here are tips on how to care for dry skin.

What Is Dehydrated Skin?

Dehydrated skin isn't a skin type, but a temporary condition caused by a lack of water in the skin. Unlike dry skin, (which lacks oil) dehydrated skin lacks hydration and can happen to anyone, even someone with oily or combination skin

Common Signs Of Dehydrated Skin

  • Your skin may feel tight, especially after cleansing even if it looks shiny
  • Dull or tired appearance
  • Dehydration exaggerates fine lines, especially around the eyes and mouth
  • Increased oiliness or breakouts
  • Sensitivity or irritation

How To Care For Dehydrated Skin

To combat dehydrated skin, it’s important to hydrate and strengthen your skin’s natural barrier.

  • Drink plenty of water throughout the day to restore hydration from within.
  • Avoid over-exfoliating or using harsh treatments like alcohol-based toners that may further strip the skin.
  • Use water-based, hydrating products. Shop our recommended products:

Common Myths About Dry & Dehydrated Skin  

Dehydrated skin means you’re not drinking enough water

While staying hydrated is important, dehydrated skin can also result from external factors like harsh weather or overuse of drying skincare products.  

Oily skin can’t be dehydrated

Oily skin can be dehydrated, especially if you’re using too many oil-controlling or mattifying products that strip your skin of water.  

Exfoliating more will fix flaky skin

Flakiness from dehydration or dryness often means your skin needs more moisture, not more scrubbing. Too much exfoliation can strip your barrier and make both issues worse.

You only need to moisturize in winter

Sun, wind, indoor AC, and even stress can all trigger dehydration—even in the summer. Keeping your skin balanced is important all-year round.
