Chemical Peels: What They Actually Do, and Why the Name Frightens People

The word chemical does this treatment no favours at all, and it hides a very ordinary idea: taking away the layers your skin's damage is sitting in. Here's what a chemical peel removes, what the Obagi Blue Peel RADIANCE is, and what the blue is for.

Put the words chemical and peel next to each other and something in most people flinches, which is a shame, because the idea underneath them is one of the plainest in skincare. Give us a few minutes and you'll have the whole of it, including what the blue in the Obagi Blue Peel RADIANCE is actually for.

What a chemical peel actually does

Here is the entire treatment in one sentence. A peel applies a carefully controlled chemical solution to the surface of your skin, removing its damaged outer layers, and the skin that surfaces in their place is smoother, softer and more even.

That really is it. Everything else on this page hangs off that one line.

Now, where has that damage been sitting all this time? Answer the question and the whole treatment turns rather ordinary.

Think of a wooden kitchen table that's been in a family for twenty years. There are rings where hot mugs stood, a scratch from something that should never have been dragged across it, and a paler patch along the side that gets the afternoon sun through the window. Take that table back by a layer and you haven't bought a new one, and nobody has added a single thing to it. It is the same wood it always was. Every one of those marks was only ever living in the part that came away.

Your skin keeps its history in much the same place. Sun damage, uneven colour, the marks that acne left behind long after the acne itself packed up: those sit in the outer layers, which is exactly why taking those layers away changes what you see in the mirror. Nothing is being covered over, and nothing foreign is arriving on your face. What you're looking at afterwards is your own skin, one layer down.

Why the word chemical puts people off

Now let's deal with the word itself, because it's doing this treatment a great deal of harm on nothing more than a misunderstanding.

Chemical describes what a thing is made of. It's a category rather than a warning, and it's an enormous category. The sharpness in a lemon is citric acid. The vitamin C in the orange sitting beside it is ascorbic acid. Neither of those has ever frightened anybody, because we know them by what they do rather than by what they're called.

And here's the part that tends to raise a smile. The word acid has already walked through this clinic wearing a completely different hat. Hyaluronic acid is what our dermal fillers are made of: a substance your own skin makes and steadily loses as the years go by. Same word, entirely different feeling attached.

So the name turns out to be the least useful thing about it. What matters is control: how much is applied, how deeply it works, and whether the person applying it can see what is happening while it is happening.

Which is precisely where the blue comes in.

What the Obagi Blue Peel is, and what the blue is for

The peel we use at Broadway Retreat is the Obagi Blue Peel RADIANCE, a recognised standard in clinical peels. It uses trichloroacetic acid in a blue base. That's a mouthful of a name, and it comes from the same habit we just met: chemistry names a substance after the parts it's built from, the way citric and ascorbic got theirs. The blue is the part that matters here, and it isn't decoration. It's the most useful thing about the whole product.

The blue lets your practitioner see exactly how deeply the peel is working on every area of your face, as it happens. So the depth is controlled rather than guessed.

Picture standing on a bridge over a river on a clear day. You can see at a single glance where the water runs shallow and where the bed drops away beneath it, the whole width of the river at once, without putting a foot in anywhere to find out. Take the colour out of that water and you'd be reduced to wading in and hoping.

That's what the blue is doing, with one difference in your favour: the person reading the depth is also the person setting it, right there as they work. And the phrase worth holding on to is on every area of your face. Your forehead isn't being treated on an assumption borrowed from your cheek, and every part of you is seen for itself as the work goes on.

You might reasonably ask why any of that is your business rather than ours. Here's why: the depth of your peel is what your result turns on, and it's what your healing period turns on too. It gets agreed with you at your consultation, where we assess your skin and settle on the depth your particular concerns call for, and that happens before anything at all is applied to your face.

What chemical peels genuinely help with

Peels are aimed at a specific family of complaints, and they have a satisfying amount in common with one another.

Acne is on the list, along with the scarring it leaves behind, and those are really two problems arriving under one name. Most faces carry more than one kind of mark once acne has finished with them, and the kinds behave differently, so we look properly rather than treating every mark as the same thing. If scarring is the main reason you're reading, our piece on why acne scars sit below the surface is worth your time, and we keep a whole suite of scar treatments so the method gets matched to the actual scar in front of us.

Sun damage comes next, and it's the one people underestimate most, because it arrives so slowly that no single summer ever seems to be the culprit. Pigmentation belongs here too, which simply means colour sitting unevenly in your skin: the patches that turned up at some point and then declined to leave.

Then the fine lines and the wrinkles, and finally the one that quietly sends a great many people looking in the first place. Dull, tired skin texture. That's the one where nothing in particular is wrong with your face and yet the surface of it looks flat and weary, whatever you've been putting on it at night.

Here's the thread running through all five. Every one of them shows itself in the material at the top of your skin, and a peel is a treatment that takes the top of your skin away. It answers those concerns for the same reason a key answers a lock.

Which also explains how it sits alongside the other things we do to skin. Microneedling asks your skin to rebuild from underneath, so its results build over months. Our thirty-minute microdermabrasion facial exfoliates the very surface with fine crystals and sends you back out with no downtime at all, and our piece on what that half hour takes off goes through it properly. That's three treatments working at three depths, and a good many faces want more than one of them across a year. It takes very little to settle which one yours is asking for, once your face is in front of us.

It isn't only for your face

This surprises people, and it's worth knowing before you book anything, because the areas nobody thinks to ask about are often the ones giving the game away.

Peels also treat the neck, the chest, the hands and the arms. Those are the parts of you that live in the same daylight as your face all year and get a fraction of the attention, which is why a photograph now and then catches them out when your face has nothing at all to answer for.

And peels work on all skin types, which is a sentence a good many people have been waiting a long time to read. If you've ever quietly wondered whether this treatment was even available to your skin, there's your answer.

Where a peel honestly stops

Every treatment has a boundary, and it's worth knowing a peel's before you book, because a good treatment pointed at the wrong problem will let you down through no fault of its own.

A peel works on the material of your skin. It doesn't put volume back. A hollow that sits there while your face is completely still is a place where fullness has gone, and replacing it is the job of dermal fillers instead.

It doesn't relax a muscle either. Lines that mostly turn up when you move, when you frown or smile or raise your brows, are made by small facial muscles creasing the skin, and anti-wrinkle injections are what those call for. Those two get mixed up constantly, so if you're not certain which of them you've been looking at, our piece on Botox and fillers sorts it out in about three minutes.

And it doesn't lift. Better skin is still skin in the same position, so where the position itself has changed, a jawline that has softened its border or a cheek sitting lower than it used to, that's a thread lift conversation or a surgical one.

None of that is a mark against peels. It's the ordinary business of a treatment being genuinely good at one job, and it's a far happier thing to hear now than to work out for yourself long after an appointment.

What the appointment involves, and the days after it

The consultation comes first, always. We assess your skin and agree the depth of peel your concerns call for, and that is the appointment doing most of the real work, because the depth is the decision everything else follows from.

Then the peel is applied, with the blue base letting your practitioner control the depth precisely across every area of your face.

After that, the damaged outer layers lift away over the following days, revealing the fresher skin beneath as they go. There is a healing period, we give you aftercare guidance for it, and we talk you through that properly rather than leaving you to look it up on your phone at eleven at night.

Now the question everybody wants answered before they book: how much peeling are you actually going to see? We're going to give you a conversation instead of a number, and the reason is an honest one. How much your skin does depends on the depth we agree at your consultation, so it's a question with an answer about your face rather than an answer in general. You'll be told exactly what to expect, by someone who has looked at your skin, before anything is applied to it.

One thing we can say plainly, though. A peel asks nothing like what invasive treatment asks of you: real change in the skin itself, without the recovery an operation demands.

Who a chemical peel tends to suit

After enough consultations, a handful of familiar people keep walking through the door.

People whose complaint is the material of their skin, not the shape of their face. They like how they look; they'd just like the top of their skin in better condition.

People carrying the evidence of sun they enjoyed at the time and have thought about rather differently since.

People with uneven colour, who have spent a small fortune on things promising to even it out from the outside.

People whose acne cleared up years ago, while the marks it left never quite got the message.

And people who want a treatment aimed squarely at the top of the skin, because they've worked out that the top of the skin is where the thing bothering them actually lives.
