In short. The lower lid is the thinnest skin on the face, and material placed near the surface can be seen through it. Depth, amount, and what can be done afterwards.
Key points
- Ask how deep the material is planned to go, what keeps it there, and how much will be placed in the first session.
- Ask what the plan is if a tint appears rather than a softened shadow, and what can be done about it.
- A clinic that answers these without hesitation is describing a plan rather than a product.
The lower eyelid carries the thinnest skin on the face, and that fact is behind most of the ways this treatment goes wrong. Material placed close to the surface can be seen through the skin that covers it. The result is a grey or blue-grey shadow that looks, from a distance, like the darkness the patient came in to have treated.
Why the tint appears
Two things are happening. Some of it is the material itself, which has a colour of its own that becomes visible when only a thin layer of skin covers it. Some of it is the way light behaves in thin tissue: light passes through the skin, meets the pale or bluish layer beneath, and returns to the eye carrying that tone. The tint varies with the light in the room.
Depth is the decision
The standard approach places material deeply, against the bone and beneath the muscle, where it fills the hollow without sitting under the skin itself. The plane is chosen from the examination, and in a face with almost no subcutaneous layer the deep plane is not merely preferable but necessary. Placing superficially fills the surface directly, which is exactly why it shows.
Amount and substance also matter
Thin skin tolerates very little before its texture changes. Material placed in larger volumes in one session is more likely to be visible, and more likely to form a ridge along its track. The substance classes are not identical here either: the more fluid or less cohesive ones show through thin tissue more readily than the firmer ones.
The questions worth asking before you agree
Ask how deep the material is planned to go, what keeps it there, and how much will be placed in the first session. Ask what the plan is if a tint appears rather than a softened shadow, and what can be done about it. A clinic that answers these without hesitation is describing a plan rather than a product.
What can be done if it happens
Some of it resolves on its own. Beyond that, the reversible class can be partly broken down, and the honest version is that dissolving is incomplete, acts on your own tissue in the same area, and carries its own risks. Classes that cannot be broken down cannot be removed at all. Where a tint has been present for months and the skin has taken on the colour, dissolving does not always reverse it.
Contact the clinic rather than waiting if
- A tint is accompanied by pain, heat, redness or a firm lump that is not softening.
- The area becomes increasingly swollen after the first week rather than settling.
- There is any change in vision, or skin turning white, grey, mottled or dusky.

Frequently asked questions
Does the grey tint always go away?
Not always. A faint tinge on the day of treatment is often swelling and the material’s own colour, and much of it fades over the first weeks. A tint still present at the review is more likely to reflect the depth the material was placed at, though it can still improve over months as the material settles.
Does dissolving always remove a tint?
No. The enzyme removes the reversible material it can reach, and where a tint has become a change in the skin over months it does not always reverse it. Dissolving is also its own procedure, with bruising, swelling and a rare reaction risk of its own, and it acts on your own tissue in the same area.
Is there a way to test whether material will show through my skin?
There is no test that predicts it with certainty, which is why the decision rests on how much tissue sits between the skin and the muscle and on how thin the skin is. Where almost nothing sits between them, the honest answer may be to decline the treatment rather than place material that cannot be hidden.
Risks & Limitations
- The infraorbital vessels run close to the plane the material is placed in, and their position varies between people. Material entering one can travel toward the circulation around the eye: skin can be lost, and in rare cases vision is affected. This is time-critical rather than cosmetic.
- The lower lid is the thinnest skin on the face, so material placed too near the surface can show through it as a grey or blue-grey tint, and a lump here is visible in a way a lump in the cheek or the jaw is not. Only the reversible class can be broken down, and dissolving is its own procedure with its own risks rather than a clean undo.
- This region drains the worst on the face. Swelling lasts longer here than anywhere else, morning puffiness can persist for months, and repeated filling raises the baseline until the under-eye is puffy in a way that reads as a bag.
- Filling a bulge makes it worse: material placed beneath a herniated fat pad raises the surface around a mound that is still there, and the eye reads heavier rather than rested. Where the finding is a fat pad, the treatment that addresses it is an operation.
When to Seek Care
- Any change in vision, including blurring or a patch of lost sight — seek emergency care immediately.
- Severe pain out of proportion to the injection, or pain that is worsening rather than settling.
- Skin turning white, grey, mottled or dusky anywhere near the treated area.
- Swelling that is increasing after the first few days rather than settling, or fever with spreading redness, warmth or discharge.
