What the gurus are saying

Gurus consistently praise Prequel's hypochlorous acid spray as an effective, affordable alternative to pricier competitors like Tower 28, with transparent labeling of pH and active percentage. The standout appeal is its fine mist application and versatility for acne, rosacea, irritation, and post-procedure healing. One caveat: the fine mist delivers product less efficiently than harsher sprays, so it depletes faster despite the lower price point.

"It's a significantly lower price point than the Tower 28 spray. The formulas are very comparable to each other. However, I kind of hate the Tower 28 packaging and I really like the Prequel packaging instead. This one has such a finer mist compared to the Tower 28 one, which is a little bit of a harsher, more direct, intense spray. This one is a very fine mist. The downside of a fine mist is that you end up going through it a lot quicker because there's more of the mist kind of lost in the air. Even though this one is more affordable than the Tower 28 spray, I do think they last about the same amount of time because the Tower 28 spray is a little bit harsher, which means you're getting all the formula delivered to your skin as opposed to the Prequel spray, which is kind of just half of it is kind of floating through the air. I personally really enjoy the Prequel packaging because the Tower 28 one is just a little bit too intense and jarring, especially when I spray it on my face in the morning."

"I love this one because it's packaged really well. It has a great pH, very simple ingredients, and it's not overpriced. It's just such a simple product. We don't need to be spending like $30 or more on hypochlorous acid. That's insane. It's like a one fix all type of product. It can help acne, rosacea, eczema, sensitive skin, can help fix or repair your skin barrier. It's great to use after the gym to cut down on bacteria on the skin. It's really, really great addition to any skincare routine."

"The best hypochlorous acid spray I've used this year by Prequel, very transparent formulation of this product here. I love this. You can use hypochlorous acid for so many things. It's one of these products that you should just keep on hand. You have it when you need it."

"I've been trying Prequel, this is also under $15. I love that this has the pH listed, it has the percentage of hypochlorous acid in it. I love to live for transparent skincare packaging, so this is a must."

"It's a nice hypochlorous acid. I've used Tower 22 and briefly the one by minimalist, and this felt really really good. I like it. If you are into hypochlorous acid, this is a good one."

"I'm going to go in with this from Prequel, it is the hypochlorous acid. This is not part of the instructions but whenever I do any kind of treatment I really do like to use hypochlorous acid. It just kills any bacteria and it feels good, helps with that redness."

"Hypochlorous acid is great for people who have reactive skin, it's antibacterial, antimicrobial, it's also just really soothing for the skin. This one's from Prequel, it's my favorite one out there, it's really affordable. I really just love the way it sprays, it's nice and soothing. I love using hypochlorous acid especially after I work out, like right after the gym when I'm not going directly into the shower, I spray this on and it helps you to just not break out. It is so nice, but I especially think it's great for post shave and when you cut yourself."

"I love it for rosacea because I'm constantly testing skincare as well and I'm breaking out my skin twice a month. Hypochlorous acid in general, over the last four months I've been using it, healing sped up definitely. Things after Botox as well and filler, giving quick sprits of that after, I feel like things are healing a bit more and calming and soothing."
Approved
"It's kind of a really great all rounder for things like acne flare ups. It's anti-microbial, anti-bacterial, so it helps calm down redness and irritated skin, breakouts. My rosacea has been silent since I've been using it. This is an amazing one from Prequel. It's really affordable compared to other ones on the market. I usually do this before any other skincare and just kind of let it dry down, after cleanse and go into it. If you're struggling with redness, skin irritation, breakouts, rosacea give Hypochlorous Acid a try."

"One thing I've added to my dermaplaning routine is I've started incorporating hypochlorous acid in the beginning to cleanse my face as well as in the end to soothe it. I've been using the one from my brand Prequel."

Fix Redness on the Face and Body | Dr. Sam Ellis
"Hypochlorous acid is a really gentle topical but it also has anti-inflammatory and antimicrobial properties so if someone kind of has chronic low-grade inflammation of their skin incorporating hypochlorous acid spray one to two times a day may help calm some of that inflammation and in turn reduce visible signs of redness. I recommend it so much and it's something that has done wonders in my own skincare routine."
