Ever notice tiny white bumps on your skin that look like whiteheads โ but donโt behave like them? If youโve tried to pop one and nothing happened (except irritation), youโre not alone.
According to dermatologist Sandra Lee, MD (aka Dr. Pimple Popper), these bumps arenโt pimples at all. Theyโre called milia โ and understanding what they are (and what theyโre not) is the key to treating them safely.
Fast Facts About Milia
- Small, firm white bumps caused by trapped keratin under the skin
- Very common in babies and newborns, but can appear at any age
- Not acne and not clogged pores, so typical acne treatments donโt work
- Popping does not remove them and can damage surrounding skin
- Can often be treated at home, but sometimes need a dermatologist

What are milia?
Milia are tiny, superficial cysts that form whenย keratin, a protein naturally found in skin, becomes trapped instead of shedding normally. They usually appear as small white or off-white bumps, typically under 3 millimeters.
Because milia sit just beneath the skinโs surface and arenโt connected to pores, they behave differently from acne. They arenโt caused by bacteria, excess oil, or inflammation, which is why squeezing or popping them doesnโt work.
Milia are usually painless and not itchy. The biggest risk comes from trying to remove them yourself, which can irritate the skin and increase the chance of scarring.

Can you prevent milia from forming?
Thereโs no guaranteed way to prevent milia entirely, but certain habits can help reduce how often they form. Prevention focuses on supporting normal skin turnover, so keratin is less likely to get trapped.
- Avoid heavy, occlusive products. Thick creams, makeup, or lip balms can slow natural shedding and trap dead skin cells at the surface. Instead, opt for lightweight hydration. Try:ย SLMD Hyaluronic Acid Moisturizer
- Exfoliate gently and consistently. Chemical exfoliants like alpha hydroxy acids and beta hydroxy acids help loosen dead skin so it can shed normally. If youโre new to exfoliation, start with a gentle option and build up slowly. Try: SLMD Salicylic Acid Cleanser,ย AHA/BHA Swipes.
- Support skin renewal over time. Retinol encourages healthy cell turnover, which can make milia less likely to form when used consistently and as tolerated. Try: SLMD Retinol Resurfacing Serum.
- Protect skin from daily sun damage. Sun exposure can interfere with normal shedding, so a lightweight moisturizer with SPF helps protect skin without feeling heavy. Try: SLMD Daily Moisturizer with SPF 15.
How do you treat milia?
Many milia resolve on their own as skin naturally renews itself. When treatment is needed, the goal is to soften trapped keratin and support gradual release โ not to aggressively target the bump.
Because milia arenโt acne, ingredients that kill acne-causing bacteria โ like benzoyl peroxide โ wonโt help. Instead, look for options that gently soften buildup while protecting the skin barrier.
Use targeted exfoliation carefully. Salicylic acid can help soften excess keratin when applied sparingly. Try: SLMD AHA/BHA Swipes.
Spot-treat existing bumps with care. These products are meant for occasional, localized use โ not daily, all-over application. Try: SLMD Salicylic Acid Pimple Patches or SA Acne Spot Treatment.
If milia are persistent, widespread, or especially bothersome, a dermatologist can remove them safely using professional extraction or in-office treatments like chemical peels or laser procedures.
Milia FAQs
Q: Are milia the same as whiteheads?
A: No โ they can look similar, but theyโre different. Milia are tiny cysts made of trapped keratin that sit just under the skinโs surface, while whiteheads are a form of acne that form inside pores from oil and dead skin. Because they form differently, milia usually wonโt respond to typical acne treatments.
Q: Can you pop milia?
A: You shouldnโt. Milia donโt have an opening like pimples, so squeezing them typically wonโt remove the bump โ it just irritates the surrounding skin and can lead to scarring. If a milia bump is stubborn or bothersome, a dermatologist can remove it safely.
Q: Do milia go away on their own?
A: Often, yes. Many milia gradually resolve as your skin naturally sheds and renews itself, but it can take time. If they persist, keep recurring, or you want faster removal, targeted at-home care or a dermatologist visit may be helpful.
Q: Why do milia show up around the eyes?
A: The skin around the eyes is thinner and more delicate, which can make it easier for keratin to become trapped โ especially if heavier creams are used in that area. Avoid using strong actives too close to the lash line unless your dermatologist has specifically advised it.
Q: When should you see a dermatologist for milia?
A: If milia donโt improve over time, keep returning, are widespread, or are bothering you cosmetically, a dermatologist can confirm the diagnosis and remove them safely. This is especially important for bumps near the eyes, where at-home picking or squeezing can cause more harm than good.
Dr. Lee's Last Word
Donโt try to pop milia โ youโll only irritate your skin. Gentle exfoliation and time usually help...and if theyโre stubborn, a dermatologist can take care of them safely.
