In short. Pigment, dullness and fine texture are within reach of a peel. The wrinkles, scarring and deeper damage it leaves untouched.
Key points
- If a line disappears when the skin around it is stretched gently, it is a surface line and a peel reaches it.
- If it remains, it lies deeper, and no number of surface peels will remove it.
- That single observation separates the problems a peel can answer from the ones it cannot, and it takes seconds to make.
A peel removes the surface layers of the skin in a controlled way, and what it can change follows directly from that. The problems that live in those layers improve; the ones that live beneath them do not, and it is worth being precise about which is which before a course is booked.
What it changes
Pigment that sits at the surface lifts with the layers removed, so uneven tone and sun-related discolouration often improve substantially, and the skin looks more even as it heals. Dullness improves along with it, because the dullest layer is the one being replaced. Fine crepe and superficial lines soften, and the surface feels smoother to the touch. A series of lighter peels builds a modest change over months with little downtime.
The stretch test
If a line disappears when the skin around it is stretched gently, it is a surface line and a peel reaches it. If it remains, it lies deeper, and no number of surface peels will remove it. That single observation separates the problems a peel can answer from the ones it cannot, and it takes seconds to make.
What it cannot change
Wrinkles that are present at rest. Textural scarring, which sits below the surface layers and needs a treatment that reaches that far. Pigment that lies deeper than the peel goes, which includes much of what is driven by a pigmentary condition rather than by sun alone. Loose skin, which a peel neither tightens nor repositions. Broken vessels, which belong to a light treatment rather than a peel. And the ageing process itself, which continues whatever is done.
What the course asks of you
Days of redness, tightness and flaking after each session, with makeup sitting poorly while the skin is renewing, and a period during which sun exposure has to be avoided. Sessions are spaced weeks apart. The result is judged against photographs taken before the course rather than against a mirror, because the change accumulates too slowly to see. And the maintenance is real: without sun protection the pigment that was lifted tends to return.
Where a peel plan goes wrong
- A course is sold for a wrinkle present at rest, which lies deeper than the treatment goes.
- Pigment is treated without establishing whether it is sun-related or driven by a pigmentary condition.
- Sun protection is treated as advice rather than as part of the plan, and the result fades within a season.
A peel is a good answer to surface pigment, dullness and fine texture, and a poor answer to a deep crease, a scar or loose skin. The pigment pages cover what drives discolouration, and the melasma pages explain why some pigment behaves differently from sun damage. What resurfacing reaches is the other side of the comparison.
Frequently asked questions
Will a peel remove my wrinkles?
Not the ones that are present at rest. A peel removes surface layers, so it improves fine crepe and superficial lines and leaves the deeper creases that come from years of movement and sun exposure. If a line is still visible when the skin around it is stretched, it lies deeper than the peel reaches, and a course of peels will not remove it however many sessions are used.
How much of my pigmentation will lift?
The pigment that sits in the surface layers often lifts substantially, which is why uneven tone and sun-related discolouration respond well. Pigment that lies deeper, or that is being driven by a condition such as melasma, behaves differently and may return or may darken after treatment. That is why the depth of the pigment, rather than its extent, is what the assessment establishes.
Does a peel tighten loose skin?
No. A peel changes the surface of the skin and does not reposition anything beneath it or remove redundancy. Skin that has lost elasticity keeps its looseness, and a face that has descended stays where it is. Where firmness or position is the complaint, a peel is answering a different question from the one being asked.
Risks & Limitations
- Both options work by injuring the skin deliberately, and pigment change is the risk they share. The risk rises with depth and is materially greater in darker skin tones, and conservative settings there are the clinical plan rather than a compromise.
- Post-inflammatory pigment change may take months to settle and may not settle completely. Treating it is harder than preventing it, and treating it with a further injury carries its own risk.
- Deeper treatment leaves skin open rather than flaking. Infection is a real risk while the skin is open, and an untreated infection can lead to scarring that is permanent.
- A cold sore flare can be triggered by either option in a patient who carries the virus. Antiviral cover before treatment reduces the risk rather than treating an outbreak that has already begun.
- Scarring after resurfacing is uncommon and is more likely after a deeper treatment, after an infection, or in a patient with a keloid tendency.
- Healing takes as long as it takes. Redness after resurfacing lasts for weeks and fades over months, and no clinician can shorten it or promise a date at which the skin will look unremarkable.
- Neither option reverses sun damage permanently. Pigment can return, the skin continues to age, and a result that is not protected with sun avoidance and sunscreen will not hold.
- Neither option tightens loose skin or repositions tissue that has descended. Those are surgical findings, and a plan that promises them with a peel or a laser has promised something the depth cannot deliver.
When to Seek Care
- Increasing pain, spreading redness, warmth or swelling in the treated area, particularly with a fever.
- Discharge that changes in colour or smell, or a wound that is not closing as expected.
- A cold sore outbreak after treatment, which needs antiviral treatment rather than time.
- A treated area becoming darker or lighter than the surrounding skin, because early pigment change is easier to manage.
- A firm, raised or thickening area in the treated skin, or a scar beginning to overgrow.
- Blistering, crusting or a burn that is not healing — contact the treating team the same day.
