Waking up with a cystic mountain on your chin is a universal rite of passage. It’s painful. It’s red. Honestly, it’s just plain annoying. When you're standing in the aisle at Target, staring at a wall of sleek, $40 glass bottles promising "botanical miracles," it’s easy to overlook the humble, white-and-blue tube of 10 benzoyl peroxide gel up and up. It looks medical. It looks boring.
But it works.
Most people treat acne treatments like a "more is better" scenario. They slather on high concentrations and then wonder why their face is peeling off like a lizard in the desert. There is a specific way to use a 10% concentration—which is essentially the "maximum strength" available without a doctor's signature—without destroying your skin barrier. We’re going to talk about why this specific generic brand has a cult following, the science of why it kills bacteria, and how to actually apply it so you don't end up with chemical burns.
Why the Up and Up Formula Hits Different
The active ingredient here is straightforward: Benzoyl Peroxide (BPO). The "10" refers to the percentage of the medication in the gel. In the world of dermatology, 10% is the heavy hitter. It’s an organic compound that works by introducing oxygen into the pores. Since Propionibacterium acnes (the bacteria that causes those deep, painful bumps) can't survive in oxygen-rich environments, the BPO basically suffocates the breakout from the inside out.
Why buy the Up and Up version instead of a name brand like Clean & Clear or Neutrogena? Honestly, it’s the inactive ingredients. Many users find the Target formulation to be slightly less "gritty" than other generics. It’s a water-based carbomer gel. This means it doesn't feel like a heavy grease slick on your face, which is the last thing you want when you're already dealing with overactive sebaceous glands.
Dr. Andrea Suarez, a board-certified dermatologist known online as Dr. Dray, has frequently pointed out that for many patients, the brand name doesn't matter as much as the vehicle of delivery. The Up and Up gel uses a simple delivery system that allows the BPO to penetrate the follicle effectively. Plus, it costs about a third of the price of the national brands. If you’re using this daily, that price gap adds up to a lot of coffee money over a year.

The Myth of the 10% Concentration
Here is a bit of a reality check. Studies, including a landmark one published in the International Journal of Dermatology, have shown that 2.5% benzoyl peroxide is often just as effective as 10% for treating inflammatory acne, but with significantly less irritation.
So why does the 10 benzoyl peroxide gel up and up even exist?
It’s for the stubborn cases. It's for body acne. It’s for the people whose skin has become "used" to lower concentrations. If you have "tough" skin or you’re dealing with back acne (bacne), that 10% kick is exactly what you need to break through the thicker skin in those areas. However, if you have sensitive or dry skin, jumping straight to the 10% gel is like trying to put out a candle with a firehose. You’ll get the job done, but you might take the table down with it.
How to Use 10% Benzoyl Peroxide Without Ruining Your Life
If you just smear this all over your face like a moisturizer, you are going to regret it. Your skin will turn red, it will itch, and it will flake. To use this product like a pro, you have to understand the "Short Contact Therapy" method or the "Sandwich" method.
Short Contact Therapy is a game changer. You apply the 10 benzoyl peroxide gel up and up to your clean, dry skin. You let it sit for maybe five to ten minutes. Then, you wash it off. Because BPO works incredibly fast, those few minutes are often enough for it to kill the bacteria, but not long enough for the medication to sink deep into the stratum corneum and cause massive dehydration.

The Sandwich Method is better for leave-on use.
- Wash your face with a gentle, non-medicated cleanser.
- Apply a thin layer of a basic moisturizer (think CeraVe or Vanicream).
- Apply a pea-sized amount of the 10% gel ONLY to the affected areas.
- Apply another layer of moisturizer on top.
This creates a buffer. It slows down the absorption rate and keeps your skin's moisture locked in while the BPO does the dirty work.
A Warning for Your Towels
There is one major downside to this product that has nothing to do with your skin. Benzoyl peroxide is a bleach. It’s a literal oxidizing agent. If you apply this and then wipe your hands on a navy blue towel, that towel is going to have orange spots by tomorrow morning. It will ruin your favorite pillowcases. It will ruin your expensive t-shirts.
Pro tip: Only use white towels and white pillowcases when you have this in your routine. Or, make sure you are washing your hands like a surgeon after every application.
Real Results vs. Marketing Hype
You’ll see a lot of reviews online saying this "cured acne overnight."

It didn't.
Acne is a slow-moving biological process. While BPO can reduce the redness and size of a pimple in 24 hours by killing the bacteria and reducing inflammation, it doesn't stop the cause of the acne, which is often hormonal or related to excess oil production. You have to be consistent. It usually takes about four to six weeks of regular use to see a genuine decrease in new breakouts.
What the 10 benzoyl peroxide gel up and up is exceptionally good at is treating "inflammatory" acne. These are the red, painful bumps. It is significantly less effective for "comedonal" acne—those tiny little skin-colored bumps or blackheads. For those, you’d be better off looking at a retinoid like Adapalene (which Target also sells under the same brand).
Safety and Sun Sensitivity
When you use a 10% gel, you are essentially stripping away the top layer of dead skin cells. This makes your "new" skin underneath extremely vulnerable to UV damage. You cannot skip sunscreen. If you use this gel in the morning and go for a walk without SPF 30, you aren't just risking a sunburn; you're risking post-inflammatory hyperpigmentation. That’s the fancy term for those dark purple or brown spots that stay on your face for months after a pimple heals. Use the BPO to kill the acne, use the sunscreen to prevent the scars.
Practical Steps for Success
Ready to try it? Don't just dive in headfirst.
- Patch test first. Put a tiny dab behind your ear or on your inner forearm for 48 hours. If you don't itch or swell, you’re likely good to go.
- Start slow. Use it every other night, or even every third night. Your skin needs to build up a tolerance to the 10% strength.
- Moisturize like it's your job. Use products with ceramides and hyaluronic acid to repair the barrier that the BPO is inevitably going to stress out.
- Watch for the "Purge." Sometimes, your skin gets worse before it gets better as the BPO forces underlying gunk to the surface. Stick with it for at least a month unless you have an actual allergic reaction (hives or extreme swelling).
- Keep it away from your eyes. The skin around your eyes is the thinnest on your body. BPO near the eyes can cause massive puffiness and irritation, even if you didn't put it directly on the eyelid.
The 10 benzoyl peroxide gel up and up is a tool. It's a powerful, cheap, and effective tool that has survived decades of skincare trends for one reason: it kills the bacteria that causes acne. Respect the percentage, protect your skin barrier, and keep your colored towels far away from the bathroom vanity.
