Do I Still Need Moisturizer If I Have Oily Skin?

Many people have talked my ears off saying that if you have oily skin, you don’t need a moisturizer, because the assumption is that excess oil already means your skin has enough moisture. I personally used to skip moisturizer because many of the ones I’ve tried made my skin feel greasy, and with the weather in the Philippines, the last thing I want is that hot, slick layer on my face.

But experts have been pushing back against that idea, clarifying that moisturizer is still essential—yes, even for oily skin, because oily skin is not a sign of excess moisture. It may actually signal a lack of it. 

To find all the answers, I reached out to board-certified dermatologists to understand the misconceptions and how I should approach my relationship with moisturizer.

Getting the wrong idea

According to board-certified dermatologist Francesca Sy-Alvarado, MD, FPDS, “Moisturizer isn’t just about adding oil to the skin. It’s about maintaining a good balance of oil and water to maintain a healthy skin barrier.”

In addition, fellow board-certified dermatologist Raissa Francisco-Passion, MD, FPDS shared in a previous Allure Philippines interview that moisturization is vital. “Moisturization means lubricating the skin, thereby reducing dryness and transepidermal water loss.”

This is why moisturizers come in different forms, each serving a specific function. Dr. Alvarado-Sy explained that emollients help fill in the gaps between skin cells, smoothing the skin and helping prevent water loss. Occlusives, on the other hand, create a physical barrier on top of the skin that seals everything in.

Even oily skin relies on this balance to function properly. “So when your skin barrier is intact, it means that your skin is better at doing its natural processes, regulating oil production,” says Dr. Sy-Alvarado. It also becomes more resilient—better able to tolerate active ingredients and defend against environmental stressors like UV exposure, pollution, and even bacteria.

Can moisturizing oily skin really worsen breakouts?

One of the biggest concerns around moisturizers for oily skin is the fear of breakouts—because with that extra layer, I feel like my pores get clogged by moisturizers too.

However, Dr. Sy-Alvarado debunks that, saying it depends on the type of moisturizer you use. Heavier, more occlusive formulations can feel greasy and, in some cases, contribute to clogged pores. This is where the term “comedogenic” often comes in, referring to ingredients that can induce the formation of comedones under testing conditions.

When breakouts do occur, they are often linked to other underlying factors such as acne-prone skin, uncontrolled acne, or conditions like seborrheic dermatitis—not moisturizers themselves. Seborrheic dermatitis typically presents as red, scaly patches in oil-rich areas such as the T-zone, eyebrows, sides of the nose, and nasolabial folds.

“I want to clarify that moisturizers aren’t the main culprit in skin breakouts,” she says.

What would happen if I skip moisturizer?

Skipping moisturizer might seem like the move to stop adding oil on the face, but according to experts, it can have the opposite effect.

“The skin can actually become dehydrated because there’s still water loss, even if your skin looks oily. So your skin can actually produce more oil to compensate for the lack of hydration. And over time, if you overproduce oil it can lead to congestion of the pores, and even more sensitive skin,” explains Dr. Sy-Alvarado. 

This becomes more pronounced when using active ingredients like retinoids or benzoyl peroxide, which can further compromise the skin barrier if not properly supported.

How can I tell if my skin is actually dehydrated?

Oily skin and dehydration can coexist. “Signs of dehydration in oily skin can translate into sensitivity. You can have tightness or discomfort, even if you are visibly oily,” says Dr. Sy-Alvarado.

Other indicators include dullness, uneven texture, flakiness, or rough patches. Increased sensitivity—such as stinging when applying products—can also point to underlying dehydration. In some cases, worsening oiliness throughout the day may signal that the skin is overcompensating.

What type of moisturizer is suited for oily skin?

“We suggest that you get the right formulation of moisturizer that can help balance your skin. And again, I emphasize, it’s not about avoiding moisturizers, but more of choosing formulations that suit your skin type,“ reminds Dr. Sy-Alvarado.

In a tropical climate like the Philippines, where heat and humidity can make skin care feel heavier, choosing the right moisturizer becomes especially important.

“Our tropical weather could be a deterrent for some when it comes to applying moisturizers, but we should still give our skin the hydration it deserves,” says board-certified dermatologist Jella Mercado-Garcia, MD, FPDS in a previous Allure Philippines interview.

“For oily skin, I recommend gel-based moisturizers that are non-comedogenic to help prevent acne,” she says. “For drier skin, a light lotion or cream can help address dehydration without that heavy, sticky feel.”

Letting go of outdated beliefs

Moisturizers sometimes get all the blame, becoming the scapegoat for breakouts and being entirely shunned by those with oily skin—something I’m guilty of as well. But with expert advice, they still need to be in our vanity drawers, now that we better understand what works for our skin and how it behaves. 

For those with oily skin, letting go of moisturizers is not the solution; it’s about letting go of the old idea that moisturizers have no place in our routines.
