Three different things can cause a soft or firm bump under the eye. Xanthelasma is a flat, pale-yellow cholesterol deposit. "Cholesterol spots" is a lay term most people use to describe xanthelasma. Milia are small, hard, white keratin cysts. Each has a different origin, a different texture, and a different treatment path. This page puts all three side by side so you can tell them apart in one read.
For the full picture on xanthelasma specifically, including causes, cholesterol links, and all treatment options, see the full xanthelasma guide.
Key takeaways
Texture and color are the fastest separators for under-eye bumps.
- Xanthelasma (cholesterol spot): flat, soft, pale-yellow plaque with a cholesterol origin.
- "Cholesterol spot" is not a separate condition. It is the everyday name for xanthelasma.
- Milia: small, hard, white keratin cyst with no cholesterol connection.
- Soft and yellow means xanthelasma. Hard and white means milia.
- If you are not certain, especially near the eyelid margin, see a dermatologist before any at-home treatment.
What each one actually is
Understanding the origin of each growth is the fastest way to separate them.
Xanthelasma
Xanthelasma is a deposit of cholesterol and lipids that accumulates in the skin cells (macrophages) of the eyelid area. Those lipid-loaded cells cluster in the dermis just under the eyelid skin, producing a soft, flat, yellowish patch. The American Academy of Dermatology classifies it as the most common type of xanthoma (lipid-deposit skin growth) and notes it as a benign cutaneous marker of lipid metabolism. It sits most often near the inner corner of the upper eyelid but can appear below the lower lid as well.
Cholesterol spots (the term)
"Cholesterol spots" is not a clinical diagnosis. It is a lay description that most people use to describe xanthelasma. When someone says they have cholesterol spots on or under their eye, they almost always mean xanthelasma. The two terms describe the same condition. There is no separate clinical entity called a "cholesterol spot" that differs from xanthelasma.
Milia
Milia are small cysts filled with keratin (a structural skin protein), not cholesterol. They form when dead skin cells become trapped beneath the surface rather than shedding normally. The result is a hard, smooth, white dome, typically 1 to 3 millimeters across. Milia do not have a cholesterol connection. They can appear anywhere around the eye, including the lower eyelid and the orbital area below the eye. For a detailed breakdown of milia specifically, the milia under the eye guide covers identification and removal in full.
Side by side: the comparison table
Read this once, then we will walk through the cues in plain English. The xanthelasma column is highlighted because it is the condition this cluster goes deeper into. The third row shows that "cholesterol spot" is a name, not a separate condition.
The most useful separator at a glance: xanthelasma is flat, soft, and yellow. Milia are hard, round, and white.
Xanthelasma and cholesterol spots: are they different things?
No. In clinical dermatology, the deposit is called xanthelasma (or xanthelasma palpebrarum). The NIH MedlinePlus skin-conditions reference and Mayo Clinic both use xanthelasma as the standard term. "Cholesterol spot" is the everyday name that patients and some general-interest websites use for the same thing.
The reason for the confusion: xanthelasma is caused by cholesterol and lipid accumulation, so calling it a "cholesterol spot" is literally accurate, just not the clinical term. If your search history includes "cholesterol spots under eyes," you are researching xanthelasma.
One practical note: "cholesterol spot" can also occasionally describe xanthomas elsewhere on the body (elbows, Achilles tendons, hands). Those are in a different anatomical zone and require a different treatment approach. Under the eye and on the eyelids, a cholesterol deposit is xanthelasma.
For the research on whether xanthelasma confirms high cholesterol levels, see are xanthelasma a sign of high cholesterol. The short version: roughly half of cases occur with entirely normal lipid panels.
How to tell xanthelasma from milia under the eye
The under-eye zone is where this distinction matters most, because both xanthelasma and milia can appear there, and they respond to different removal methods.
The four identification cues
Feel it. Xanthelasma is soft. If you press very gently (do not apply real pressure to the orbital area), a xanthelasma deposit gives slightly rather than feeling like a hard bead. Milia feel firm, like a tiny marble under the skin.
Look at the color. Xanthelasma is pale yellow or cream. Milia are distinctly white or off-white. If what you see is clearly white, not yellow, milia is the more likely candidate.
Look at the shape. Xanthelasma is flat or nearly flat. Milia are raised domes. An under-eye growth that is noticeably round and raised points toward milia.
Check the location more specifically. Xanthelasma forming below the lower lid tends to sit toward the inner corner. Milia under the eye are typically distributed across the entire orbital area, sometimes appearing in small clusters.
If you are still uncertain after this check, the three-way comparison with syringoma added (another condition that clusters under the eye) is in the complete xanthelasma vs milia vs syringoma guide.
The one structural cue that separates all three
Color and location can mislead. The one cue that holds across almost every case:
- Xanthelasma (cholesterol spot): flat, waxy, yellow plaque
- Milia: round, hard, white dome
If what you have is flat and yellow, treat it as xanthelasma. If it is round, hard, and white, treat it as milia. Each has its own removal approach and its own appropriate tool.
Flat and yellow is xanthelasma. Round and hard and white is milia. That single cue resolves almost every under-eye case without a doctor visit.
At-home treatment
For confirmed xanthelasma under the eye, the plasma pen is the at-home method that matches the mechanism used in clinical settings: delivering focused plasma energy to the lipid deposit so the skin can renew. Treatment takes about 5 minutes per spot. A small protective scab forms and falls off on its own between Days 3 and 7. By Weeks 2 to 3, the treated area has typically renewed.
The OcuraLife 6-in-1 Skin Imperfection Removal Pen offers 9 adjustable power settings, which matters for the delicate under-eye area. Use conservative settings near the eye and confirm the deposit is not resting directly on the eyelid margin before treating at home. For deposits on or within a few millimeters of the lash line, the clinical route is the right call.
For the full breakdown of at-home vs clinical options, including what does not work on cholesterol deposits, see the at-home removal guide.
When in doubt, see a dermatologist
If you are not certain whether the growth is xanthelasma or milia, see a dermatologist before any at-home treatment. The treatments differ, and using the wrong approach delays resolution. Specifically, see a dermatologist if:
- You cannot confidently tell xanthelasma from milia by the cues above.
- The deposit sits directly on the eyelid margin or within a few millimeters of the lash line.
- The growth has changed quickly in size, color, or shape.
- The growth is irregularly shaped, pigmented, or bleeds. Those features do not belong to xanthelasma or milia and need professional evaluation.
- You have multiple new deposits appearing before age 35, which warrants cardiovascular assessment per research reviewed on NCBI.
When to see a dermatologist
See a dermatologist rather than treating at home if any of the following applies.
- You are not confident whether the growth is xanthelasma or milia. The treatments differ and using the wrong approach delays resolution.
- The deposit sits directly on the eyelid margin or within a few millimeters of the lash line.
- The growth has changed quickly in size, color, or shape.
- The growth is irregularly shaped, pigmented, or bleeds. Those features do not belong to xanthelasma or milia and need professional evaluation.
- You have multiple new deposits appearing at a younger age (under 35), which warrants cardiovascular assessment per research reviewed on NCBI.

The bottom line
"Cholesterol spots" and xanthelasma are the same condition: a soft, flat, pale-yellow lipid deposit, most common after 40, with a sometimes-but-not-always connection to elevated cholesterol. Milia are hard, white keratin cysts with a completely different origin and a different removal path. The fastest separator is texture and color: soft yellow means xanthelasma; hard white means milia.
