Chemical peel (Chemical exfoliation (chemexfoliation))

What is a chemical peel?

A chemical peel applies a solution to the skin that causes the outer layers to shed, so newer skin can come through. It is used to improve dull or uneven skin, mild sun damage, some pigmentation and fine surface lines, and sometimes acne.

Peels come in three broad depths. Superficial (light) peels affect only the outer layer and need a course for a gradual effect. Medium-depth peels reach a little deeper for more noticeable change but with more downtime. Deep peels reach further into the skin, can give the most change, but carry the most risk and the longest, most demanding recovery.

What a peel can achieve depends heavily on its depth, the solution used, your skin type and the practitioner's skill. Light peels give subtle results; deeper peels do more but are riskier. A peel does not lift sagging skin, remove deep folds or replace volume.

Peel depth and risk go hand in hand. Deeper peels carry a real risk of pigment changes and scarring, particularly in darker skin tones, and deep phenol peels can affect the heart and need medical monitoring.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Options at a glance

These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.

Preparing for your procedure

• Have a consultation with a suitably qualified practitioner who assesses your skin type and what depth is appropriate.
• Tell them about cold sores, a tendency to scar or keloid, recent sun exposure, pregnancy and all medicines and skincare.
• Mention if you take or have recently taken the acne medicine isotretinoin (Roaccutane), as resurfacing is usually delayed after it.
• Follow any skin-preparation routine you are given (for example specific creams or sun avoidance) in the weeks before.
• Use strict sun protection before and after, as sun exposure raises the risk of pigment problems.
• Arrange downtime appropriate to the peel depth, especially for medium and deep peels.
• Discuss antiviral tablets beforehand if you are prone to cold sores.

What happens

The skin is cleaned and prepared. The practitioner applies the chemical solution, usually with a brush or applicator, and leaves it on for a controlled time before neutralising or removing it. You may feel tingling, warmth or stinging, which is stronger with deeper peels.

Light peels take only a few minutes and you can usually return to normal activities. Medium and deep peels take longer, may need cooling or pain relief, and deep peels may be done with sedation or local anaesthetic and require monitoring of your heart and fluids.

Afterwards your skin may look red, tight or, with deeper peels, swollen, before it flakes and peels over the following days to weeks as new skin appears.

Is this procedure right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

Comfort, sedation or contrast choices

If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.

The main risks are pigment changes and, with deeper peels, scarring. People with darker skin tones are more prone to pigment problems and need careful assessment and an appropriate choice of peel. Deep phenol peels can be absorbed into the body and affect the heart, so they should only be done in a properly equipped, monitored setting by an experienced clinician. Strict sun protection before and after lowers the risk of pigment problems.

Published figures to discuss

The chance and type of complication depend strongly on peel depth, the solution used, skin type and aftercare, so a single complication rate is not meaningful across all peels. In general, light peels are low-risk, while deeper peels carry a real risk of pigment change and scarring, more so in darker skin. Picking the skin or sun exposure during healing increases these risks. Phenol-based deep peels carry a specific risk of heart rhythm problems from absorption.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

Recovery depends entirely on the depth. Light peels may cause only a day or two of flaking, while deep peels involve significant swelling, redness and peeling and can take two weeks or more before the skin looks presentable.

• Redness and a tight feeling soon after treatment
• Flaking and peeling over the following days
• Temporary darkening or extra sensitivity of the skin
• Longer-lasting pinkness after medium and deep peels
• Gradual improvement over a course of light peels rather than after one

Aftercare

• Use only the gentle cleansers and moisturisers your practitioner recommends.
• Apply high-factor sun protection every day and avoid sun exposure while healing.
• Do not pick, scratch or peel the flaking skin, as this can cause scarring or pigment changes.
• Avoid make-up, exfoliating products and active skincare until your practitioner says it is safe.
• Avoid saunas, heavy exercise and very hot environments while the skin settles.
• Take any prescribed antiviral or other medicines as directed.
• Attend follow-up, especially after a deep peel, so healing can be checked.

• High-factor sunscreen ready
• Recommended gentle cleanser and moisturiser
• Antiviral tablets if prescribed for cold sores
• Time off appropriate to the peel depth booked
• Written aftercare instructions
• A contact route for problems or signs of infection

Scars and how they heal

Light peels do not normally cause scars. Deeper peels carry a real, if uncommon, risk of scarring, including raised or keloid scars, particularly if the skin is picked while healing or if you are prone to scarring. Pigment changes (darker or lighter patches) are more common than true scars and are more likely in darker skin. Sun protection and not picking the skin reduce these risks.

⚠ Get urgent help if…

• Spreading redness, heat, swelling, pus or fever (signs of infection)
• Painful blisters, crusting or skin breakdown beyond what you were told to expect
• A cold sore outbreak spreading across the treated area
• Skin that is unusually dark, white or scarred as it heals
• Severe or worsening pain rather than settling discomfort
• After a deep peel: palpitations, dizziness or feeling unwell (seek urgent medical help)

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A good result is smoother, brighter, more even skin, with some improvement in fine lines or pigmentation. Light peels give subtle, gradual change over a course; deeper peels give more but with more risk and downtime. The final result is judged once the skin has fully healed, which can take weeks after a deeper peel.

A peel improves the skin surface. It cannot lift sagging skin, remove deep folds or replace lost volume, and results vary with skin type and sun habits afterwards.

Results are not permanent. Skin keeps ageing and responds to sun exposure, so improvements fade over time. Light peels are often repeated as maintenance, while the effect of a deeper peel can last longer. Daily sun protection and good skincare help results last. How long any peel lasts varies a lot between people.

Related tests, treatments or support

Peels are sometimes used alongside other skin treatments such as laser resurfacing, or with injectables that treat different problems (anti-wrinkle injections for movement lines, fillers for volume). Combining treatments, or having peels too often or too deep, can increase the risk of irritation, pigment problems and scarring, so spacing and planning matter. A careful clinician tailors this to your skin rather than stacking treatments.

Follow-up & long-term care

Light peels usually need review only to plan the next in a course. Medium and especially deep peels need follow-up to check healing, manage redness or pigment changes, and guide when you can resume normal skincare and sun exposure.

• Daily high-factor sun protection to protect results and reduce pigment problems.
• A gentle, suitable skincare routine as advised.
• Repeat light peels periodically if recommended, rather than over-treating.
• Review with your practitioner if pigmentation or texture concerns return.

Repeat, follow-on and what comes next

• Light peels are usually repeated as a course rather than 'revised'.
• Pigment changes after a peel may need creams, time, sun avoidance or further treatment to settle.
• Scarring after a deep peel can be hard to correct and may need specialist input.
• An under-treated result may be improved with further sessions, but over-treatment cannot simply be reversed.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

• Clear written aftercare with sun-protection and no-picking advice.
• A plan for what to do if pigment changes, infection or scarring occur.
• Antiviral cover arranged if you are prone to cold sores.
• Follow-up appropriate to depth, with close review after deep peels.
• Honest advice on realistic results and spacing of repeat treatments.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• The depth and type of peel, and the solution used
• Who performs it and their training (a deep peel needs an experienced clinician)
• Number of sessions in a course
• Whether monitoring, sedation or local anaesthetic is needed (deep peels)
• Skin-preparation products and aftercare included
• Clinic location and setting

• The practitioner's fee and their qualifications
• The peel depth and type, and the number of sessions
• Whether skin-preparation products and aftercare are included
• For deep peels, whether monitoring and follow-up are included
• What is covered if there is a pigment problem, infection or scarring
• Cancellation policy and total cost of a course

On the NHS? Cosmetic chemical peels are private only, though some peels for skin conditions such as acne or pigmentation may be provided by an NHS dermatology service when clinically indicated.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a specialist safely

• Check the specialist is on the GMC Specialist Register for this area.
• Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
• You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
• Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including any follow-up — before you decide.
