VI Peel vs ZO 3 Step Peel
The VI Peel is finished when you leave the clinic. Everything after that is aftercare — products that protect the skin while it sheds. The ZO 3-Step Peel keeps going at home for several days. Its third step is a cream you keep applying yourself, and it counts as part of the treatment rather than as recovery care.

Side by side
The differences that matter
What it is
VI Peel
A branded pre-mixed peel
Made by Vitality Institute Medical Products. Clinics buy it in sealed variants. Each targets a different concern and comes with a take-home kit.
ZO 3-Step Peel
A branded peel built as three steps
Made by ZO Skin Health. The first two steps are done in the clinic. You complete the third at home over the days that follow.
What you actually do
VI Peel
One visit, then a week of aftercare
You go home with the solution still on your skin. Nothing goes on your face for four hours. Then the post-care kit begins.
ZO 3-Step Peel
One visit, then a defined home phase
The clinic does the first two steps, then hands over the third with instructions for the days after.
What happens at home
VI Peel
Aftercare, not treatment
Post-care kit products only, for the full shedding week. SPF 50 daily, cool water, gentle cleansing. No exercise for 3 to 4 days, or a week if you get dark marks easily.
ZO 3-Step Peel
An active step, plus aftercare on top
The home step is part of the peel, not recovery care. Missing it, or doing it wrong, is not the same as skipping a moisturizer.
What is actually in it
VI Peel
Named acids, but no percentages
The face formulas name five actives. Two are trichloroacetic acid and phenol. The others are retinoic acid, salicylic acid and vitamin C. Other variants add hydroquinone or benzoyl peroxide. No strengths are given.
ZO 3-Step Peel
Not published by the maker
Clinic pages often quote a specific acid mix and percentage. None of it traces back to ZO. Treat any strength you are quoted as the clinic's claim.
What the evidence looks like
VI Peel
One small study of 30 people
Everyone in it also got botulinum toxin the same day, so the peel's own effect cannot be separated out. There was no control group. Reported gains were 60 percent for wrinkles, 59 percent for even pigment and 70 percent for skin tone.
ZO 3-Step Peel
No published trial identified
Searches for studies of ZO peels return nothing. That is an absence of evidence, not proof it does not work.

VI Peel
Downtime and sessions
VI Peel
Shedding starts around day three
It runs three to four days. The maker suggests three to six peels, every four to six weeks, then about four a year. That is a protocol, not a trial result.
ZO 3-Step Peel
A multi-day course by design
The shedding phase falls inside the home phase. The maker publishes no session count. Ask the clinic what course they advise, and why.
Cost
VI Peel
No reliable published price
No society survey, dataset or list price exists. Everything out there is clinic menu pricing.
ZO 3-Step Peel
No reliable published price
The same gap applies. Ask whether the take-home products are in the quote or billed on top. That is where the two most often differ.
Who tends to be happy with it
VI Peel
- Best for - Someone who wants the treatment finished when they walk out.
- Best for - Anyone whose week cannot fit a daily task at a fixed time.
- The mindset - The clinic owns the result. Your job is sunscreen and patience.
- Worth knowing - The four-hour rule matters. Nothing goes on the skin until it has passed.
ZO 3-Step Peel
- Best for - Someone happy to take an active part for several days after the visit.
- The mindset - Half of this happens at your bathroom sink. Read the sheet first.
- Worth knowing - Get the home instructions in writing before you book.
Skin tone
VI Peel
The VI Peel maker says all its treatments are safe for all skin tones. No published trial supports that. Its own aftercare gives people prone to dark marks a longer break from exercise, which is the more useful signal.
Common questions
Questions Patients Ask
What is the actual difference between a VI Peel and a ZO 3-Step Peel?
Where the treatment finishes. The VI Peel is applied in the clinic and everything after that is aftercare. The ZO peel is built as three steps, with the third completed by you at home over the following days as part of the treatment. One is an appointment; the other is an appointment plus a home phase.
Do I have to do anything at home after a VI Peel?
Yes, but it is protection rather than treatment. No makeup or topical products for the first four hours, then post-care kit products only for the shedding week, SPF 50, cool water and gentle cleansing, no exercise for 72 to 96 hours (seven days if you are prone to hyperpigmentation), no swimming for 7 to 10 days and no direct sun for seven days.
How strong is the ZO 3-Step Peel?
Nobody outside the company can tell you. ZO does not publish the formula or the concentrations where the public can read them, and the specific percentages quoted on clinic pages cannot be traced back to the manufacturer. If the strength matters to your decision, ask the clinic for the manufacturer's written instructions for use.
Which costs more?
There is no reliable published price for either, so any comparison would be guesswork. No professional society, government dataset or manufacturer publishes a price for a branded peel. When you ask a clinic, ask specifically whether the take-home products are included in the quoted price - that is where the two most often differ.
Which is better for sun damage and uneven tone?
Neither has been shown to be better, because neither has been tested against the other or against anything else. The VI Peel's only published data comes from an uncontrolled 30-person study in which the peel was given with botulinum toxin on the same day, and no published trial of the ZO peel has been identified. The peels with actual comparative evidence for pigment are unbranded agents such as glycolic acid, Jessner's solution, TCA and salicylic-mandelic combinations, and those trials mostly find them about equal to each other.
Is either one FDA approved?
No. The FDA stated on 30 July 2024 that it has not approved any chemical peel products and that consumers should only use them under the supervision of a dermatologist or licensed and trained practitioner. No peel holds a drug approval or a device clearance. That is a statement about the regulatory route, not a judgment that peels do not work.
What happens if I miss a day of the home step?
Ask the clinic that question before you book, and get the answer in writing. With a peel whose third step is part of the treatment rather than aftercare, missing a day is not the same as skipping a moisturizer, and there is no published protocol you can look up to work it out yourself.
Safety to keep in mind
Neither peel is FDA approved, because no chemical peel product is. In a drug alert dated 30 July 2024 the FDA said it has not approved any chemical peel products, and that consumers should only use them under the supervision of a dermatologist or a licensed, trained practitioner. Neither is FDA cleared either — no chemical peel has been cleared as a device. What is regulated federally is the claims a seller makes: in July 2024 the FDA acted against sellers of very high-strength peel solutions sold direct to the public, treating them as unapproved new drugs. Who may legally apply a peel is set state by state.
Neither manufacturer publishes ingredient percentages, and neither has to: professional-use-only products are exempt from the ingredient-declaration rules that apply to consumer cosmetics. ZO also gates its professional product area, so its protocol and formula are not public. If peel strength matters to your decision, ask the clinic for the manufacturer's instructions for use in writing.
