Those Tiny Dots on Your Nose Aren’t Blackheads — Here’s What Sebaceous Filaments Really Are

Don’t be misled by face filters or edited images of celebrities—real skin has texture. It’s normal to have areas that are darker, like under the eyes, or spots that are puffy, wrinkled, freckled, marked, or uneven. These are all natural features. However, some skin issues, such as severe acne or dryness, can be uncomfortable and might signal underlying health concerns. Due to unrealistic beauty standards that promote flawless, smooth skin, people often mistake natural features for problems. For example, sebaceous filaments are often confused with blackheads, but they actually serve an important function in maintaining healthy skin.

Sebaceous Filaments: What You Need to Know

You might have noticed tiny dots scattered across your face—particularly on your nose, cheeks, chin, or forehead. While they might look like clogged pores or blackheads, they’re likely sebaceous filaments. These are tube-like structures inside your pores, and they shouldn’t be picked at.

“Sebaceous filaments can resemble blackheads, but they’re typically lighter in color—more tan or gray—and they play a key role in skin health, so it’s best not to disturb them,” explained Dr. Dendy Engelman, a board-certified dermatologist in New York City. “They naturally help transport oil from the sebaceous glands to the skin’s surface, keeping it moisturized and protecting it from environmental damage.”

Despite looking similar, they’re actually quite different. “Pimples are typically caused by bacteria or fungus and appear as raised bumps that may have a white or black top—what we commonly call whiteheads or blackheads,” explained Dr. Purvisha Patel, a board-certified dermatologist, in an interview with Skin Wellness Dermatology. “In contrast, sebaceous filaments consist only of oil and keratin, without any bacterial involvement. They’re completely harmless.” While they might not be visually appealing, sebaceous filaments aren’t a cause for concern and don’t usually require a dermatologist’s attention—unlike persistent or severe acne.

Are Sebaceous Filaments Common?

Everyone has sebaceous filaments, but they tend to be more noticeable in some people than others. Just like many aspects of skin health, factors such as genetics and age play a major role. For example, individuals with thicker hair follicles often have more visible filaments. During puberty, sebaceous glands become larger and more active, making the filaments more apparent. As we age, the skin naturally loses elasticity, causing pores to stretch and the filaments to stand out more.

According to the Cleveland Clinic, one factor you can control is your skincare routine. Over-washing or frequent sun exposure can dry out the skin, prompting sebaceous glands to enlarge in an effort to produce more oil and keep the skin hydrated.

Why You Shouldn’t Pick at Sebaceous Filaments

You might have come across videos showing how to extract sebaceous filaments—while they may be oddly satisfying to watch, skincare experts strongly advise against trying it yourself. These thread-like structures are essential for keeping the skin naturally lubricated, helping it stay soft and moisturized.

Even if you do remove them, the results are temporary. Within a few weeks, the pores will fill with sebum again, and the filaments will reappear. A more effective and skin-friendly approach is using a good cleanser to help minimize the appearance of pores—though it won’t eliminate them completely.

Additionally, squeezing sebaceous filaments can harm your skin and worsen its appearance. “Applying too much pressure can injure the outer layer of skin, causing breaks, scabs, or even infections,” explained Dr. Joshua Zeichner, a board-certified dermatologist from New York City. Other possible effects include redness, inflammation, dark spots, pimples, and scarring. To prevent these problems, avoid picking at your skin and consult a professional if you want safe removal.

Lately, beauty influencers have been promoting a trend called “skin gritting,” which claims to remove sebaceous filaments. The method starts by softening the skin with an oil-based cleanser, followed by applying an acid exfoliant. Next, a clay product infused with essential oils is used, and finally, the face is massaged with the oil cleanser for up to 15 minutes.

Grit on the Skin: Real or Residue?

“Using a combination of an exfoliating acid, a purifying mask, and an oil can provide a deeper cleanse by helping to remove pore-clogging debris,” explained Dr. Engelman. “However, much of the gritty residue you feel is often just leftover product from your skincare routine. Over time, this method can actually cause the skin to loosen and pores to appear larger.”

Cleaning Sebaceous Filaments: What Works and What Doesn’t

Keep in mind that sebaceous filaments are a natural and healthy part of your skin. While social media influencers might promote quick fixes for flawlessly smooth skin, that’s not how real skin works. Instead of aiming for “perfect” skin, focus on maintaining its health.

Luckily, you can develop a skincare routine that helps reduce the appearance of sebaceous filaments. Look for products containing ingredients like alpha hydroxy acids, oil-absorbing clay, retinol, salicylic acid, sulfur, and vitamin E. At the same time, steer clear of pore-clogging ingredients such as petroleum, coconut oil, shea butter, and tea tree oil. Keep your cleansing routine simple—using too many products isn’t always beneficial. Introduce new products gradually to see how your skin responds and avoid making things worse.
