The Acne Guide
Back, chest and shoulder acne. Does laser work beyond the face?
Laser for active acne isn't a face-only treatment. Pink's long-pulsed Nd:YAG protocol also treats the back and buttocks, using the same gland-calming mechanism that treats facial breakouts, with body skin and treatment areas calibrated at consultation rather than a single fixed setting applied everywhere.
If you've spent years assuming laser for acne was something people did for their face, you're not alone, and you're not wrong to have assumed it. Most of what gets written about acne treatment defaults to the face without saying so. Meanwhile the breakout on your back has been there long enough that you've stopped mentioning it, mostly because a t-shirt covers it and nobody's asked.
It also treats the body. Pink's long-pulsed Nd:YAG protocol, the same one covered in laser for active acne, extends to the back and buttocks as named, bookable treatment areas, not as an afterthought tacked onto a facial course.
Does the same laser treat back and chest acne?
Yes, the mechanism doesn't change by location. As explained in more depth in Pink's main article on laser for active acne, the long-pulsed Nd:YAG at 1064nm works by reaching the overactive gland and the inflammatory tissue around it, calming the process driving the breakout rather than targeting a lesion on the surface. That mechanism is the same whether the skin in question is on a cheek or a shoulder blade. If you want the fuller explanation of how and why it works, that article is the place to read it. This one is about what's different when the area is your back, chest or shoulders rather than your face.
What's actually different about treating body acne?
A few things, and they're worth naming honestly rather than glossing over.
It's often been there longer. Facial acne tends to get addressed sooner, partly because it's harder to ignore and partly because there's no shirt to pull over it. Back and chest acne is easier to keep private, and easier to keep putting off. By the time people come in asking about it, it's often more established than a comparable facial presentation would be, simply because it's had a longer, quieter run.
Friction and occlusion play a bigger role. The back, chest and shoulders sit under clothing, backpack straps, sports bras and gym equipment in a way the face doesn't. That combination of sweat, friction and material sitting against skin for hours at a time is a genuine aggravating factor for this pattern, distinct from what drives facial breakouts. It's not the only cause, and it's not something you need to diagnose yourself before booking a consultation, but it's part of why body acne behaves the way it does.
Body skin is thicker. The skin on the back in particular is structurally different from facial skin, and treatment area and approach are calibrated for that at consultation. This isn't a case of running the facial setting on a bigger patch of skin. It's a separate calibration, done by a clinician looking at your actual skin, the same way facial treatment is.
What does this mean for scarring?
Because body acne, and back acne in particular, tends to be more inflammatory and often goes untreated for longer, it's also more prone to leaving marks or genuine scarring behind. If that's already happened, and what you're looking at now is less about active breakouts and more about the texture or marks they left, that's a different conversation. Pink's articles on the different types of acne scarring and how acne scars are treated cover that ground.
Where is this actually treated on the body?
Pink's Active Acne Treatment page lists Full Back, Half Back and Buttocks as booking areas alongside the facial areas (Full Face, Cheeks, Forehead, Décolletage, Neck, Face & Neck). Area and session count are set at consultation against what your skin is actually doing, the same way they are for a facial course. There's no separate body-acne product to search for. It's the same treatment, extended to where the breakouts are.
Frequently Asked Questions
Does Pink treat chest and shoulder acne, or only the back?
The mechanism and consultation approach apply across the torso. Pink's current named booking areas on the body are Full Back, Half Back and Buttocks, and a consultation is the right place to talk through a chest or shoulder presentation and how it fits the available areas.
Is back acne treated differently from facial acne?
The underlying mechanism is the same long-pulsed Nd:YAG protocol described in Pink's main active-acne article. What changes is the calibration: body skin is generally thicker than facial skin, and treatment area and approach are adjusted for that at consultation rather than applied as a fixed setting regardless of location.
Why does back acne seem worse than my facial acne ever was?
A few reasons can combine. Back acne is easier to leave untreated for longer because it's hidden by clothing, and friction, sweat and occlusion from clothing, backpacks and gym equipment are aggravating factors specific to the back, chest and shoulders. Body acne also tends to skew more inflammatory, which is part of why it can look more established by the time someone seeks treatment.
Can body acne leave scars the way facial acne can?
Yes, and because it often goes untreated for longer, it can be more prone to leaving marks or true scarring behind. If that's already the case for you, Pink's articles on types of acne scarring and how acne scars are treated are the next useful read.
More on Pink's Active Acne Treatment
If the back, chest or shoulders are where your acne actually lives, the next honest step is the same as it would be for facial acne: a proper look at your skin. Pink's Active Acne Treatment page sets out how the Nd:YAG course works across both face and body areas, including how areas and sessions are structured once your skin has been assessed in person.
