It is controlled exfoliation.
A chemical agent creates a controlled skin injury.
Chemical Peel vs Glycolic Acid Peel
Chemical Peel: An acid solution applied in the office to shed the top layers of skin. Superficial peels clear pores and fade brown marks; medium peels reach texture and deeper sun damage. It does not fix indented scars.
Glycolic Acid Peel: A chemical peel that uses glycolic acid, the smallest of the fruit acids. It brightens dull skin, softens rough texture and fades flat brown marks. It works on the surface only, and it has to be neutralized on time.
Choose Chemical Peel if…
Choose for brown marks, clogged pores or dull, sun-aged texture — not for indented scars.
- Melasma or dark marks alongside creams
- Clogged pores and mild acne
- You can avoid sun before and after
Choose Glycolic Acid Peel if…
Choose to brighten dull skin and fade flat brown marks with little or no downtime.
- Dull skin or rough texture
- Flat brown marks or clogged pores
- You want little downtime
Alternatives, not combined
Can you have both?
A glycolic peel is one type of chemical peel. You would choose one peel per session.

What is it?
There are three depths.
Superficial, medium and deep peels differ in recovery and risk.
The acid name is not enough.
A peel is not defined by ingredient or percentage alone.
Deep peels need a medical setting.
Phenol peels carry serious systemic risks.
It is a supervised peel.
A glycolic acid peel is an alpha-hydroxy acid exfoliation.
The percentage is not the whole story.
Acidity, contact time and technique matter.
High-strength home use is unsafe.
The FDA warns against unsupervised strong peels.
History matters.
Irritation, recent procedures, herpes and pigment risk are reviewed.

Diagram explanation
The agent and depth are selected: The clinician matches the peel to the skin and concern. Controlled chemical injury occurs: The chosen agent acts on the planned skin layers. Skin heals and renews: Results and recovery depend on the peel depth and technique.

The peel is applied: A clinician selects the formulation for the skin and goal. Outer cells loosen: Glycolic acid reduces cohesion in the superficial skin layers. The surface renews: Controlled exfoliation can improve selected superficial concerns.

Before your treatment
Chemical Peel
Glycolic Acid Peel
2–4 weeks before
2 weeks before: Sun and tanning: No tanning, no sunburn.
4 weeks before: Pigment cream: On deeper skin tones, a pigment-blocking cream first cuts the risk of dark patches.
2 weeks before: Sun and tanning: No tanning or sunburn for 2 weeks beforehand, and sunscreen daily.
Pigment cream: On deeper skin tones, and in anyone who marks easily, many providers pre-treat for 2 to 4 weeks with a pigment-blocking cream to lower the chance of dark patches.
Before you book: Events: Do not book a first peel in the days before an event.
The week before
Actives and hair removal: Stop retinoids, benzoyl peroxide and acids 3 to 5 days before.
Actives and hair removal: No waxing, threading or hair removal creams.
Actives and hair removal: Stop retinoids (tretinoin, adapalene, retinol), benzoyl peroxide and exfoliating acids 3 to 5 days before.

Arrival & prep
Skin is checked, photos taken, and you confirm what you have stopped using.
Skin is checked and usually photographed, and you confirm what you stopped using.
Treatment
Skin is cleaned and degreased, eyes and lips protected, acid brushed on in layers.
It stings and builds over 2 to 5 minutes, then gets neutralized. The visit takes 20 to 30 minutes. A light peel burns briefly and most people tolerate it; a medium peel is genuinely uncomfortable, and the burning can last an hour.
Skin is cleaned and degreased, eyes and lips protected, and the acid brushed on in a set order.
The provider watches for even pinkness, then neutralizes or floods the skin with water. It takes about 20 to 30 minutes. The sting is hot and prickly, climbs over 2 to 5 minutes, then stops seconds after neutralizing. Say so if it turns to burning, which is the signal to stop early.
Before you leave
Pink, tight skin, sometimes with mild swelling and stinging for a few hours.

First 24 hours
Days 1 to 3: Skin darkens slightly, dry and rough.
Day 1 to 3: Skin feels dry and rough and can look slightly darker before it sheds.
Days 2–7
Days 4 to 7: Light peels finish flaking.
Day 3 to 5: Flaking finishes and skin looks brighter underneath.
Weeks 2–4
Weeks 1 to 2: Some people break out for a week or two as clogged pores clear.
Week 1 to 2: A few spots in the first week or two as clogged pores clear are common, and settle on their own.

Cost
Per session
A superficial salicylic or glycolic peel runs about $100 to $300 a session in the US, a medium-depth peel about $400 to $900.
In the US a superficial glycolic peel usually runs about $100 to $250 a session, depending on the city, a medical office versus a spa, and whether it is bundled with a facial.
Insurance
Insurance rarely covers peels for acne or post-acne marks — they count as cosmetic.
Insurance does not cover peels done for brightness, texture or post-acne marks.
Questions
Chemical Peel
Glycolic Acid Peel
Individual Questions
Do chemical peels work for acne scars?
Not for indented scars. Peels fade the flat brown or red marks left after a spot — people call those scars, but they are discoloration. Depressed scars need microneedling, lasers, subcision, or filler.
Which peel is best for acne?
Salicylic acid, usually — oil-soluble, so it works inside the pore. Glycolic acid suits surface dullness and pigment. Some providers combine them, or use a salicylic-mandelic blend on deeper skin tones.
How many do I need?
4 to 6 sessions, 2 to 4 weeks apart, then maintenance. One peel gives a temporary glow.
Are peels safe on deeper skin tones?
Superficial salicylic and glycolic peels are, with good data behind them. Deeper peels can leave a lasting dark or light patch. Depth, not the acid, matters.
Will I actually peel?
Often not much, and that is fine. Sheeting does not mean it worked; mild flaking does not mean it did not.
How is a glycolic peel different from a salicylic peel?
Glycolic is water-soluble and works on the surface, so it suits dullness, rough texture and brown marks. Salicylic is oil-soluble and gets inside the pore, so it suits blackheads and whiteheads. Some providers blend the two.
What does neutralizing mean, and why does it matter?
Glycolic keeps working until it is stopped, either with a basic solution or by flooding the skin with water. The provider watches a timer and the skin at the same time. Peels left on too long are how burns happen.
Is a higher percentage better?
Not on its own. The pH and the contact time matter as much as the number. A well-judged 30% peel can do more than a careless 70% one.
Will I actually peel?
Often only lightly, and sometimes not at all. Fine flaking for a day or two is usual, and no flaking does not mean it failed.
How many will I need?
4 to 6 peels, 2 to 4 weeks apart, then maintenance every couple of months. One peel gives roughly a week of brightness.
Can I have one if I use tretinoin?
Yes, and skin on a retinoid usually peels more evenly. Stop it about 3 to 5 days before and restart once flaking has finished.
Keep exploring.
