Is Your Skin Oily or Dehydrated? Here’s How to Tell (And What to Do About It)
When your skin is oily but still firm, or your makeup simply refuses to play nice no matter what you do, it's confusing. Are you using the wrong foundation? Is your moisturizer too hydrating? Or is your skin just being finicky?
The real issue might be this: you're treating oily skin, but your skin is actually dehydrated—or both.
Understanding the difference between oily and dehydrated skin is the most important first step in formulating an efficient skincare and makeup regimen. Misunderstanding your skin's message will mean using the wrong products, and more damage than benefit can be caused. Let's dissect.
Oily vs. Dehydrated Skin: What's the Difference?
Although they sound familiar, oily and dehydrated skin are different:
- Oily skin is a skin type, i.e., it's a permanent characteristic that overproduces sebum (oil).
Dehydrated skin is a short-term skin state—it means your skin is lacking water, not oil. Any skin type, oily skin or dry skin, can become dehydrated.
It's important because the management of oily skin (oil-controlling and mattifying products) can dry the skin further—and in reverse.
How to Identify Oily Skin
You likely have oily skin if you observe the following:
- A shiny appearance within hours of washing
- Persistent blackheads, whiteheads, or acne
- Bigger, open pores (especially in the T-zone)
-
Makeup "slides off" or wears down too soon
- Rarely experiences tightness or areas of dryness
Oily skin can be helped with gentle exfoliation, oil-free moisturizers, and matte-finish primers and foundations. Steer clear of rough cleansers that strip the skin, as they will cause your skin to produce more oil in an attempt to compensate.
How to Identify Dehydrated Skin
Dehydrated skin, however, appears differently:
- Skin tight, itchy, or sensitive after washing
- Fine lines are more noticeable (particularly around the eyes and mouth)
- Skin looks dull, flaky, or rough
- Tendency to irritate or become red
- Abrupt oily skin that senses "off," tight, or inflamed
One of the biggest signs of dehydration is when your skin is producing oil, but still senses dry on the inside. You might feel like you are oily, but really your skin is hungry for water.
To repair it, layer your skincare: begin with a hydrating serum, follow with a moisturizer that traps water, and don't over-exfoliate or use too many actives simultaneously.
Can Skin Be Oily and Dehydrated Simultaneously?
Yes—and it's surprisingly common! Particularly in tropical climates or during the changing of seasons, your skin may begin to produce more oil in order to protect itself, yet internally not be hydrated enough.
This combination results in:
- Shiny, oily-looking skin that remains tight
- Dry, flaky spots combined with acne
- Caked-on foundation in some areas and sliding off in others
To get your skin into balance:
- Use a moisturizing toner or mist before your serum
- Use a water-based, oil-free moisturizer
- Use hydrating face masks once or twice weekly
- Avoid stripping your skin with heavy foaming cleansers
How This Affects Your Makeup Application
Makeup looks its best on well-prepped skin. If your base isn't balanced, no amount of high-end foundation will last.
If you have oily skin:
- Use a mattifying primer
- Choose an oil-free foundation
- Set your makeup with a translucent setting powder
- Blot excess oil throughout the day using blotting sheets
If you have dehydrated skin:
- Start with a hydrating serum or mist
- Apply a hydrating primer and dewy foundation
- Avoid heavy powders—use a hydrating setting spray to set moisture
Mixing the right prep and skincare products ensures a smooth finish that lasts all day.
Product Types to Add to Your Skincare Routine
No matter your skin type, the right product types can balance and restore it.
For oily skin, use:
- Lightweight gel cleansers
- Lightweight gel moisturizers
- Clay or charcoal face masks
- Non-comedogenic mattifying primers
For dehydrated skin, use:
- Hydrating serums with hyaluronic acid
- Facial mists with rose water or aloe
- Cream-based moisturizers
