That can be especially critical to keep in mind if you’re treating acne, since many acne-fighting ingredients, like salicylic acid and glycolic acid, can be drying on skin—which is how they work. “Skin that is too dry will produce more oil to compensate,” says Dr. Ibrahim. “Those that live in dry climates can also benefit from applying moisturizer, as dry air stimulates the sebaceous gland, too.”
Is serum or moisturizer better for oily skin?
It depends on your skin. If you live in a humid climate, a hydrating serum may offer enough nourishing ingredients for your skin. That may be the case in the summer, too, says Dr. Ibrahim, who notes that sunscreens often contain emollient ingredients that offer moisture.
However, for most people, a true moisturizer may be better. “Although a hydrating serum can provide moisture, it typically lacks the emollient ingredients that lock in moisture and provide a protective barrier,” says Dr. Lolis.
What to look for in a moisturizer for oily skin
First, look for the word “non-comedogenic” on the packaging. That means that it won’t clog the pores, which could trigger acne. Next, look for gel-like or lightweight textures, says Dr. Ibrahim. “These moisturizers tend to have a higher ratio of humectants and emollients over occlusives,” he explains. If you don’t want to do a deep dive into an ingredient list, the texture can often be a quick tip-off as to whether it’s suitable for oily skin.
However, a peek at the ingredient list can still be helpful. Dr. Lolis recommends looking for lightweight hydrators, such as hyaluronic acid and glycerin; as humectants, these draw water into the skin. She also points to niacinamide, which can help regulate oil production, whereas salicylic acid can help unclog pores and fight bacteria.
On the other hand, steer clear of butters and waxes. “Those with oily skin may find that a moisturizer that’s higher in occlusives to be too rich, as if it just sits on top of the skin,” says Dr. Ibrahim. He also advises against formulas that contain waxes or wax esters, as they can also feel too heavy for oily skin.
How often should you be moisturizing if you have oily skin?
Moisturizing should be a daily habit. Apply it directly after your serum to help seal in active ingredients and lock in moisture. Again, the only shift in your routine should come with the seasons: a hydrating serum in the summer may suffice, whereas a standard moisturizer is preferable the rest of the year.
Can moisturizer cause acne in oily skin?
Depending on the formulation, it’s entirely possible for moisturizer to cause acne, especially if it contains comedogenic ingredients—meaning they clog pores. To avoid that, “always look for moisturizers that are non-comedogenic,” says Dr. Lolis.
