1. How a peel works
A peel applies a chemical agent that breaks the bonds between skin cells or coagulates protein to a controlled depth. The damaged tissue separates and is shed, and the skin repairs. The repair is the point: new tissue laid down in response to controlled injury tends to be more even in texture and pigment than what was there before.
Everything else follows from how deep that injury goes. Depth determines what conditions can be addressed, how long the skin takes to recover, and what can go wrong.
2. Superficial peels
These act on the epidermis, the outermost layer. Typical agents include glycolic and other alpha hydroxy acids, salicylic acid, mandelic acid and low strength trichloroacetic acid. Downtime is minimal: some redness, a day or two of tightness and light flaking.
What they realistically deliver is improved surface texture, a temporary reduction in dullness, some help with congestion and blackheads, and modest improvement in very superficial pigmentation over a course. They will not remove a static line, will not treat deep pigmentation and will not tighten anything. They are sold as a course, usually four to six sessions two to four weeks apart, and a single session is a demonstration rather than a treatment.
3. Medium depth peels
These reach through the epidermis into the upper dermis, usually with higher concentration trichloroacetic acid, sometimes in combination. This is a different proposition. Expect several days of visible peeling, a week or more before you would want to be photographed, and a period of pinkness that can last for weeks.
In exchange, the range of things that can improve widens: sun damage, some types of pigmentation, fine lines and superficial scarring. It is also where the risk profile becomes clinically significant. Post inflammatory hyperpigmentation, particularly in richer skin tones, is a real and common complication. Infection, prolonged redness and pigment loss are all possible.
4. Deep peels
Phenol based deep peels reach the mid dermis and produce the largest change of the three. They also carry the largest risks, including cardiac effects from systemic absorption during the procedure, permanent pigment change, prolonged healing and scarring. They require medical assessment, monitoring and structured aftercare.
A deep peel is a medical procedure. It should be discussed with a doctor with relevant training, in a setting equipped for it, and it is not something to arrange because a treatment menu offered it.
5. Skin tone changes the calculation
Richer skin tones carry a higher risk of post inflammatory hyperpigmentation after any controlled injury to the skin, including peels, lasers and microneedling. That is not a reason to avoid treatment. It is a reason for the assessment to include a proper discussion of your skin type, a conservative starting point, appropriate pre treatment and a plan for managing pigment change if it occurs.
A practitioner who treats every skin the same way with the same protocol has not accounted for the single most important variable in this treatment category.
Superficial chemical peel, single session
Superficial peels use inexpensive, well established acids, so the price is mostly the practitioner's time and the assessment. That is why the band sits low and why it is fairly tight.
Courses are the norm rather than the exception. Six sessions at the middle of this band is the number to compare against other options, not one session at the bottom of it.

6. What peels do not do
They do not tighten loose skin. They do not remove deep static lines. They do not treat vascular redness or thread veins, which need light based treatment. They do not stop skin ageing, and any improvement they produce is undone by sun exposure faster than most people expect.
They also do not replace a routine. Peeling skin every month while doing nothing between appointments is an expensive way to keep starting over. The evidence for daily sun protection and, where appropriate, a topical retinoid is stronger than the evidence for most in clinic procedures, and it costs less.
Medium depth peel, single session
A medium peel involves a genuine recovery period, a pre treatment regime, and follow up. The price reflects clinical time before and after the procedure as much as the procedure.
A medium peel priced like a superficial one is either not a medium peel or is not being supported with the assessment and aftercare it requires.

7. Aftercare, which is most of the outcome
Do not pick or pull peeling skin. Doing so is the most reliable route to scarring and pigment change. Keep the skin protected from the sun completely for the period the clinic specifies, and take that instruction seriously rather than as a suggestion. Expect the skin to be more reactive than usual for several weeks.
Ask before the appointment what the aftercare requires, what products you will need and what the plan is if the skin does not settle. Our page on aftercare that matters covers which instructions are supported and which are folklore.
8. Deciding whether a peel is the right tool
If the complaint is dullness and rough texture, a course of superficial peels is a reasonable and proportionate option, alongside or instead of microneedling.
If the complaint is pigmentation, the first question is what kind. Sun damage, melasma and post inflammatory pigmentation respond very differently, and melasma in particular can be worsened by aggressive treatment. That is a conversation for someone who can diagnose the pigmentation rather than simply treat it.
If the complaint is laxity, this is the wrong page and probably the wrong category. The British Association of Dermatologists publishes patient information that is a useful counterweight to a treatment menu.
