One of the most common skincare mistakes I see is avoiding moisturizer.
Many people believe moisturizers are only necessary for dry skin. Others worry that moisturizing will make their skin oily, clog pores, or contribute to breakouts. As a result, they skip one of the most important steps in maintaining healthy-looking skin.
What many people do not realize is that hydration and oil production are not the same thing. Skin can be oily and dehydrated at the same time. In fact, some of the most dehydrated skin I see belongs to people who describe themselves as oily.
Daily moisturizing helps support hydration, maintain skin comfort, and strengthen the skin barrier. If you're unfamiliar with the role the skin barrier plays in overall skin health, read our guide to What Is the Skin Barrier? Regardless of skin type, it remains one of the simplest and most important habits for healthier-looking skin.
Why Every Skin Type Needs a Moisturizer
One of the biggest misconceptions in skincare is that oily skin does not need moisturizing.
Many people assume that moisturizers need to feel rich, heavy, or deeply occlusive to be effective. What many people do not realize is that hydration and oil production are not the same thing.
Skin can be oily and dehydrated at the same time. This is one of the most misunderstood skin conditions and something I discuss in more detail in Why Is My Skin Oily But Dehydrated? In fact, some of the most dehydrated skin I see belongs to people who describe themselves as oily. When the skin lacks moisture, it may compensate by producing more oil, creating an imbalance that can contribute to congestion and breakouts.
Whether your skin is dry, oily, sensitive, acne-prone, or aging, daily moisturizing helps maintain comfort, balance, and resilience.
What Moisturizers Actually Do for the Skin
Help Maintain Hydration
Moisturizers help reduce water loss from the skin and support hydration throughout the day. Properly hydrated skin tends to appear smoother, healthier, and more radiant.
Support the Skin Barrier
The skin barrier acts as the body's first line of defense against environmental stressors. Moisturizing helps support this protective barrier and promotes better moisture retention.
Improve Comfort and Resilience
Well-moisturized skin often feels less tight, less reactive, and more comfortable overall. Skin that is properly hydrated is generally better equipped to tolerate active ingredients such as retinoids, exfoliants, and vitamin C.
Improve the Appearance of Skin Texture
Consistent moisturizing can help soften rough areas and improve the overall appearance of skin texture and smoothness.
Help Reduce Transepidermal Water Loss (TEWL)
One of the primary functions of a moisturizer is helping reduce transepidermal water loss (TEWL), the natural process by which water evaporates from the skin into the environment.
While some water loss is normal, excessive TEWL can leave skin feeling dehydrated, tight, sensitive, and uncomfortable. Moisturizers help support the skin barrier and improve moisture retention, making it easier for the skin to hold onto the hydration it already has.

Why People Avoid Moisturizer
"My Skin Is Oily"
Oily skin still requires hydration. The key is choosing a moisturizer appropriate for your skin type and concerns.
"Moisturizers Break Me Out"
Not all moisturizers are created equal. Heavy, occlusive formulas may not be suitable for everyone, but lightweight moisturizers can provide hydration without overwhelming acne-prone skin.
"I Use Hydrating Serums Instead"
This is one of the most common misconceptions I encounter.
Many people replace moisturizer with hydrating serums, believing they serve the same purpose. While serums can be excellent treatment products and hydration boosters, they are not designed to replace a moisturizer.
Think of a serum as a booster. It may deliver hydration and beneficial ingredients, but it does not necessarily provide the lasting moisture support that a moisturizer is designed to offer.
In most routines, the two work best together. A serum helps enhance the routine, while a moisturizer helps seal in hydration and support the skin throughout the day.
Choosing the Right Moisturizer
For Oily, Combination, and Acne-Prone Skin
Lightweight moisturizers can help maintain hydration without feeling heavy or greasy. The goal is balance, not stripping the skin of moisture. My recommendation: Daily Moisturizer.
For Dry or Depleted Skin
Richer moisturizers can help support comfort, reduce the feeling of tightness, and provide additional barrier support. My recommendation: Onerta® Cream Barrier.
For Sensitive Skin
Focus on moisturizers that prioritize hydration and barrier support while minimizing unnecessary irritation. Depending on your skin's needs, Daily Moisturizer or Onerta® Cream Barrier can both be excellent options.
What Insisting on Moisturizing Has Taught Me About Skin
For years, I have encouraged clients to moisturize consistently, even when they were convinced they did not need to.
Some believed their skin was too oily. Others worried that moisturizer would clog their pores or contribute to breakouts. Many replaced moisturizer with hydrating serums, assuming the two served the same purpose.
Time and again, I observed the same pattern: skin often became more comfortable, balanced, and resilient when moisturizing became consistent.
Some of the most meaningful improvements I have seen did not come from adding stronger actives or more complicated routines. They came from supporting the skin with the basics and giving it what it needed every day.
Daily moisturizing may not be the most exciting step in skincare, but it remains one of the most important.
FAQ
Do I need a moisturizer if I have oily skin?
Yes. Oily skin still requires hydration. The goal is to choose a moisturizer appropriate for your skin type and concerns.
Can moisturizer cause breakouts?
Some formulas may not be suitable for acne-prone skin, but properly chosen moisturizers can help support balance and hydration without contributing to congestion.
Is a hydrating serum the same as a moisturizer?
No. Serums and moisturizers serve different functions and often work best when used together.
How often should I moisturize?
Most people benefit from moisturizing twice daily, once in the morning and once in the evening.
What happens if I stop moisturizing?
The skin may become increasingly dehydrated, uncomfortable, and less resilient over time.
Healthy-looking skin is rarely the result of a single product. More often, it comes from consistent habits practiced every day. Daily moisturizing remains one of the simplest and most effective ways to support the skin's long-term health and appearance. Skin rarely complains about being properly moisturized, but it often lets you know when it isn't.
If you're not sure where to begin, start with a cleanser, a moisturizer, and a consistent routine. The basics often accomplish far more than people expect.
